The following are health and medical definitions of terms that appear in the papaya (carica papaya) - oral article.
Allergic reaction: The hypersensitive response of the immune system of an allergic individual to a substance.
Breast milk: Milk from the breast. Human milk contains a balance of nutrients that closely matches infant requirements for brain development, growth and a healthy immune system. Human milk also contains immunologic agents and other compounds that act against viruses, bacteria, and parasites. Since an infant's immune system is not fully developed until age 2, human milk provides a distinct advantage over formula.
Breathing: The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction and then exhaled due to muscle relaxation.
Chest: The area of the body located between the neck and the abdomen. The chest contains the lungs, the heart, and part of the aorta. The walls of the chest are supported by the dorsal vertebrae, the ribs, and the sternum. Also known as thorax.
Chest pain: Pain in the chest that can be a result of many things, including angina, heart attack (coronary occlusion), and other important diseases. Chest pain is a warning to seek medical attention, so one should try not to ignore chest pain and 'work through it.'
Diabetes: Refers to diabetes mellitus or, less often, to diabetes insipidus. Diabetes mellitus and diabetes insipidus share the name "diabetes" because they are both conditions characterized by excessive urination (polyuria).
Dizziness: Painless head discomfort with many possible causes including disturbances of vision, the brain, balance (vestibular) system of the inner ear, and gastrointestinal system. Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions ranging from lightheadedness, unsteadiness to vertigo.
Drain: A device for removing fluid from a cavity or wound. A drain is typically a tube or wick. As a verb, to allow fluid to be released from a confined area.
Enzymes: Proteins that act as a catalysts in mediating and speeding a specific chemical reaction.
Esophagus: The tube that connects the pharynx (throat) with the stomach. The esophagus lies between the trachea (windpipe) and the spine. It passes down the neck, pierces the diaphragm just to the left of the midline, and joins the cardiac (upper) end of the stomach. In an adult, the esophagus is about 25 centimeters (10 inches) long. When a person swallows, the muscular walls of the esophagus contract to push food down into the stomach. Glands in the lining of the esophagus produce mucus, which keeps the passageway moist and facilitates swallowing. Also known as the gullet or swallowing tube. From the Greek oisophagos, from oisein meaning to bear or carry + phagein, to eat.
FDA: Food and Drug Administration.
Flush: (1) A redness of the skin, typically over the cheeks or neck. A flush is usually temporary and brought on by excitement, exercise, fever, or embarrassment. Flushing is an involuntary (uncontrollable) response of the nervous system leading to widening of the capillaries of the involved skin. Also referred to as a blush (or, as a verb, to blush). Flushing may also be caused by medications or other substances that cause widening of the capillaries, such as niacin. (2) Flush also means to wash out a wound or body area.
Generic: 1. The chemical name of a drug. 2. A term referring to the chemical makeup of a drug rather than to the advertised brand name under which the drug may be sold. 3.A term referring to any drug marketed under its chemical name without advertising.
Heartburn: An uncomfortable feeling of burning and warmth occurring in waves rising up behind the breastbone (sternum) toward the neck. It is usually due to gastroesophageal reflux disease (GERD), the rise of stomach acid back up into the esophagus. Heartburn has nothing whatsoever to do with the heart. It is a popular nonmedical term. It is medically called pyrosis.
Herbal: 1. An adjective, referring to herbs, as in an herbal tea.
Infant: A young baby, from birth to 12 months of age.
Infection: The invasion and multiplication of microorganisms such as bacteria, viruses, and parasites that are not normally present within the body. An infection may cause no symptoms and be subclinical, or it may cause symptoms and be clinically apparent. An infection may remain localized, or it may spread through the blood or lymphatic vessels to become systemic (bodywide). Microorganisms that live naturally in the body are not considered infections. For example, bacteria that normally live within the mouth and intestine are not infections.
Intestinal parasite: A parasite (an organism that lives in or on and takes its nourishment from another organism) in the intestinal tract. Intestinal parasites include both helminths and protozoa. Helminths are worms such as tapeworms, pinworms, and roundworms. All of these worms can live, but typically not reproduce, inside the human intestine. In contrast to worms, which are composed of many cells, protozoa are single-celled organisms that can multiply inside the body. Examples of protozoa that can live in the intestinal tract are Giardia and Cryptosporidium.
Laboratory: A place for doing tests and research procedures, and for preparing chemicals and some medications. Also known as lab.
Liver: The largest solid organ in the body, situated in the upper part of the abdomen on the right side. The liver has a multitude of important and complex functions, including to manufacture proteins, including albumin (to help maintain the volume of blood) and blood clotting factors; to synthesize, store, and process fats, including fatty acids (used for energy) and cholesterol; to metabolize and store carbohydrates (used as the source for the sugar in blood); to form and secrete bile that contains bile acids to aid in the intestinal absorption of fats and the fat-soluble vitamins A, D, E, and K; to eliminate, by metabolizing or secreting, the potentially harmful biochemical products produced by the body, such as bilirubin, from the breakdown of old red blood cells and ammonia from the breakdown of proteins; and to detoxify, by metabolizing and/or secreting, drugs, alcohol, and environmental toxins.
Liver disease: Liver disease refers to any disorder of the liver. The liver is a large organ in the upper right abdomen that aids in digestion and removes waste products from the blood.
Mouth: 1. The upper opening of the digestive tract, beginning with the lips and containing the teeth, gums, and tongue. Foodstuffs are broken down mechanically in the mouth by chewing and saliva is added as a lubricant. Saliva contains amylase, an enzyme that digests starch. 2. Any opening or aperture in the body. The mouth in both senses of the word is also called the os, the Latin word for an opening, or mouth. The o in os is pronounced as in hope. The genitive form of os is oris from which comes the word oral.
Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia. Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors.
Pancreas: A spongy, tube-shaped organ that is about 6 inches long and is located in the back of the abdomen, behind the stomach. The head of the pancreas is on the right side of the abdomen. It is connected to the upper end of the small intestine. The narrow end of the pancreas, called the tail, extends to the left side of the body. The pancreas makes pancreatic juices and hormones, including insulin and secretin. Pancreatic juices contain enzymes that help digest food in the small intestine. Both pancreatic enzymes and hormones are needed to keep the body working correctly. As pancreatic juices are made, they flow into the main pancreatic duct, which joins to the common bile duct, which connects the pancreas to the liver and the gallbladder and carries bile to the small intestine near the stomach. The pancreas is thus a compound gland in the sense that it is composed of both exocrine and endocrine tissues. The exocrine function of the pancreas involves the synthesis and secretion of pancreatic juices. The endocrine function resides in the million or so cellular islands (the islets of Langerhans) that are embedded between the exocrine units of the pancreas. Beta cells of the islets of Langerhans secrete insulin, which helps control carbohydrate metabolism. Alpha cells of the islets of Langerhans secrete glucagon, which counters the action of insulin.
Pancreatitis: Inflammation of the pancreas. Of the many causes of pancreatitis, the most common are alcohol consumption and gallstones. Other causes include medications (azathioprine, estrogen, thiazides, metronidazole, valproic acid, and tetracycline), trauma, abdominal surgery, abnormalities of the pancreas and intestine, and infections such as mumps. Acute pancreatitis usually begins with pain in the upper abdomen that may last for a few days. The pain may be sudden and intense, or it may begin as a mild pain that is aggravated by eating and slowly grows worse. The abdomen may be very tender. Other symptoms may include nausea, vomiting, and fever. The patient often feels and looks very sick. Chronic pancreatitis usually follows many years of alcohol abuse and may cause pain; malabsorption of food, leading to weight loss; and diabetes, if the insulin-producing cells of the pancreas (islet cells) are damaged.
Parasite: A plant or an animal organism that lives in or on another and takes its nourishment from that other organism. Parasitic diseases include infections that are due to protozoa, helminths, or arthropods. For example, malaria is caused by Plasmodium, a parasitic protozoa.
Pharmacist: A professional who fills prescriptions and, in the case of a compounding pharmacist, makes them. Pharmacists are very familiar with medication ingredients, interactions, and cautions.
Poison: Any substance that can cause severe organ damage or death if ingested, breathed in, or absorbed through the skin. Many substances that normally cause no problems, including water and most vitamins, can be poisonous if taken in excessive quantity. Poison treatment depends on the 'substance.
Poison control center: A special information center set up to inform people about how to respond to potential poisoning. These centers maintain databases of poisons and appropriate emergency treatment. Local poison control centers should be listed with other community-service numbers in the front of the telephone book, and they can also be reached immediately through any telephone operator.
Pregnancy: The state of carrying a developing embryo or fetus within the female body. This condition can be indicated by positive results on an over-the-counter urine test, and confirmed through a blood test, ultrasound, detection of fetal heartbeat, or an X-ray. Pregnancy lasts for about nine months, measured from the date of the woman's last menstrual period (LMP). It is conventionally divided into three trimesters, each roughly three months long.
Pregnant: The state of carrying a developing fetus within the body.
Prescription: A physician's order for the preparation and administration of a drug or device for a patient. A prescription has several parts. They include the superscription or heading with the symbol "R" or "Rx", which stands for the word recipe (meaning, in Latin, to take); the inscription, which contains the names and quantities of the ingredients; the subscription or directions for compounding the drug; and the signature which is often preceded by the sign "s" standing for signa (Latin for mark), giving the directions to be marked on the container.
Prothrombin: A coagulation (clotting) factor that is needed for the normal clotting of blood. A cascade of biochemical events leads to the formation of the final clot. In this cascade, prothrombin is a precursor to thrombin.
Rash: Breaking out (eruption) of the skin. A rash can be caused by an underlying medical condition, hormonal cycles, allergies, or contact with irritating substances. Treatment depends on the underlying cause of the rash. Medically, a rash is referred to as an exanthem.
Warfarin: An anticoagulant drug (brand names: Coumarin, Panwarfin, Sofarin) taken to prevent the blood from clotting and to treat blood clots and overly thick blood. Warfarin is also used to reduce the risk of clots causing strokes or heart attacks.
