a pathologic condition that results when the blood pH increases to more than 7.45. In serious cases, it can lead to coma

molecule containing thousands of genes that make up an individual's genetic code. Often referred to as a double helix, DNA is inherited from parents and carries the code for an individual's characteristics such as eye or hair color, height, etc.
digestive system
body system referring to organs in the gastrointestinal (GI) tract that break down food chemically and physically into nutrients that can be absorbed by the body's cell and allow the elimination of waste products of digestion
a specific, measurable condition characterized by specific clinical symptoms, patient history, and laboratory or radiology results
a generic term referring to any pathologic condition of the mind or body
anatomical term meaning distant or away from point of attachment
surface region of the body characterized y the back (or posterior) area and including the cranial and spinal cavities
endocrine glands
ductless glands that release their secretions (hormones) directly into the bloodstream
exocrine glands
glands that secrete fluids through channels or ducts (e.g. sweat, saliva, mucus, digestive juices).
frontal plane
imaginary line running lengthwise on the body from side to side, dividing the body into anterior and posterior sections
gastrointestinal system
also referred to as the digestive system; body system that breaks down food chemically and physically into nutrients that can be absorbed and transported throughout the body to be used for energy by all body cells and, to eliminate the waste products of digestion through the production of feces.
located on a chromosome, it is a unit of heredity capable of reproducing itself exactly during cell division; it is made of segments of DNA
the study of blood and blood-forming tissues
the process of blood cell formation that occurs in the bone marrow
hemoglobin (Hgb)
the molecules that carry oxygen and carbon dioxide in the RBCs.
means literally "remaining the same"; also referred to as a steady-state condition, it is a normal state that allows the body to stay in a healthy balance by continually compensating with necessary changes
body substances secreted from glands that play a role in growth and development, fluid and electrolyte balance, energy balance, and acid-base balance
human immunodeficiency virus (HIV)
a virus spread by sexual contact or exposure to infected blood
a subjective, non-measurable term for any departure from wellness (pain, suffering, distress)
the study of diseases of the immune system; allergic disorders
integumentary system
body system referring to skin, hair, sweat and oil glands, teeth, and fingernails; involved in protective and regulatory functions
directional term meaning towards the sides of the body
directional term meaning toward the midline of the body
pigment in the skin that provides color and protects underlying tissues from absorbing ultraviolet rays
protective membranes that cover the brain and spinal cord
metabolic acidosis
a pathologic condition that occurs when the kidneys cannot eliminate acidic substances (e.g., in diabetes mellitus). It can result in kidney (renal) failure and death
metabolic alkalosis
a pathologic condition that results from excessive vomiting or an abnormal secretion of certain hormones that cause's excess elimination of hydrogen ions (from CO2)
an important bodily function that allows the formation or breakdown of substances (e.g., proteins) for the purpose of using energy
the study of microbes; microbiologic tests typically use specialized media to detect the growth of infectious microbes from bodily specimens
