Anatomy and Physiology In Health and Disease

Antibiotic a substance that acts against bacteria; it inhibits bacterial growth Bacteria a single-celled microscopic organism that does not contain a nucleus Body Cavity a region or space containing organs in a multicellular organism Cells basic unit of structure for all living things Diaphragm a large muscle that aids in breathing Mediastinum the middle section of the chest activity Meninges membranes that cover the rain and spinal cord Multicellular composed of two or more cells Organs two or more tissues working together Systems a group of organs working together to accomplish a specific task Tissues a group of cells working together to perform a function Unicellular composed of one cell Cardiac pertaining to the heart Gland structure that synthesizes and releases a substance Homeostasis a state of dynamic stability in a changing environment (alternatively, maintaining a relatively constant internal environment in spite of changes in the external environment) Hormone the body's chemical messengers Metabolism sum of the chemical reactions that take place in body Acquired Disease a disease that is not genetic in origin Bacteria a single-celled microscopic organism that has no nucleus Disease disorder which causes disruption in structure or function of an organ or system Fatigue general feeling of lack of energy or sleepiness Fever an increase in body temperature in response to infection Fungi nonphotosynthetic, single or multi-cellular eukaryotic organisms that have a cell wall Genetic Disease a disease of genetic origin that can be passed on to offspring Inflammation a condition where a site becomes red, swollen, and painful Insulin the hormone secreted by the pancreas that aids in regulating blood sugar Pain an uncomfortable feeling that can be mild or severe Parasite an organism that lives at the expense of another living organism Virus a microscopic agent that causes infection; it is not a cell and is not considered living Acute a situation that is difficult or bad; refers to an immediate situation Benign noncancerous Carcinogen a cancer-causing agent Chemotherapy using chemical agents to combat disease Chronic a long-term condition or situation that is bad or difficult Genes the unit of heredity composed of DNA Genetic relating to genes or inheritance Malignant cancerous Mutation a mistake or error in the DNA code Prognosis the expected course of a disease Radiation high-intensity electromagnetic waves Terminal a disease that will lead to death Tumor an abnormal growth of tissue Amputation removal of a limb Hyperglycemia high blood sugar Hypoglycemia low blood sugar Insulin a chemical produced by the pancreas needed in the use of glucose for energy Ketones a biological molecule produced during fat breakdown Socioeconomically Disadvantaged an individual of minority status who is living at a low-income level Ulceration the development of an open sore Abscess a localized collection of infected fluid and pus Pandemic an epidemic of disease that spans the globe Prognosis the expected outcome of a disease Third World Country a developing country with poor standard of living, poor human rights, and many social issues
