Phys - Definitions Flashcards
Physiology Definitions
adhesion
abnormal union of bodily tissues
(i.e. a knot)
Physiology Definitions
alveoli
air sacs of the lung where gas exchange takes place
millions of sacs make up the lungs
Physiology Definitions
anemia
deficiency of red blood cells
Physiology Definitions
artery
carry blood away from the heart
Characteristics:
thick walls
rounded lumen
no valves
pulsations
Physiology Definitions
arterioles
smallest branches of arteries
Physiology Definitions
arthro
joint
Physiology Definitions
ATP
(adenosine triphosphate)
supplies muscles w energy
Physiology Definitions
DNA
(deoxyribonucleic acid)
material that contains the information that determines inherited characteristics
Physiology Definitions
emphysema
disease in which the tissues of the lungs lose elasticity, making breathing difficult
Physiology Definitions
glycogen
form of glucose stored in the liver
used for quick energy, but results in muscle fatigue
Physiology Definitions
hemoglobin
iron-contained protein in red blood cells that carries oxygen for delivery to cells
Physiology Definitions
interstitial
space between cells/tissue/stuff in the body
Physiology Definitions
lactic acid
waste prodeuct produced during the anaerobic metabolism of glucose
contributes to muscle fatigue during exertion and development of oxygen debt
Physiology Definitions
ligament
connects bone to bone
Physiology Definitions
lymph
fluid that circulates throughout the lymphatic system
Physiology Definitions
myositis
inflammation of muscle tissue
Physiology Definitions
peristalisis
contraction of smooth muscle tissue to propel food/chyme through digestive tract
Physiology Definitions
plasma
fluid portion of blood consisting of a pale yellowish fluid containing proteins, salts, and other substances
Physiology Definitions
scoliosis
lateral S-curve in the spine
