TEAS Practice
11 - ANS-in mammals there are ___ major organ systems
5 quarts - ANS-How much blood does an adult have?
absorption - ANS-the passage of nutrients through plasma membranes into the blood or
lymph and then to the body
acidois - ANS-hyperventilation can increase blood pH during ____ (blood pH too low)
actin - ANS-the thin filament is composed of _____
action potential - ANS-messages sent across the plasma membrane of neurons when it
is stimulated past a necessary threshold
afferent (sensory) nerves - ANS-bring signals from the sensory organs and the muscles
to the central nervous system
airway - ANS-nose, nasal cavity, mouth, pharynx, larynx, trachea, bronchi, and bronchial
network
alkalosis - ANS-high blood pH, slowing breathing will help lower blood pH
all - ANS-____ cells contain DNA and RNA and can synthesize proteins
alveoli - ANS-one cell thick allowing for gas exchange with blood capillaries that
surround them
anaphase - ANS-the pairs of chromosomes called sister begin to pull apart and may
bend, when they are separated they are called daughter chromosomes, grooves appear
in the cell membrane
arterial blood pressure - ANS-transports oxygen poor blood into the lungs and oxygen
rich blood to the body tissues
arterioles - ANS-where adjustments are made in blood delivery to specific areas based
on complex communication from body systems
,atrial contraction - ANS-fills the ventricles
autonomic nervous system (ANS) - ANS-maintains homeostasis within the body through
direction from the hypothalamus, controls functions of internal organs, blood vessels,
smooth muscle tissues, and glands, regulates HR, breathing rate, body temp, and blood
pH
axon - ANS-insulated by oligodendrocytes and myelin sheath, contains gaps called
nodes of Ranvier, transmits impulses away from the cell body, terminates at the
synapse
Bartholin's glands - ANS-produce a mucus secretion to lubricate the vagina
bile - ANS-useful in breaking down fasts and is stored in the gall bladder between meals
blood - ANS-helps maintain internal environment in animals by carrying raw material to
cells and removing waste products, helps stabilize internal pH and hosts various kinds
of infection fighters
blood - ANS-transports oxygen to cells and removes wastes, also carries hormones and
defends against disease
blood pressure - ANS-the fluid pressure generated by the cardiac cycle
bone - ANS-a hard tissue that supports and protects softer tissues and organs. Its
marrow produces red blood cells.
brainstem - ANS-(midbrain, pons, medulla oblongata)
info from body is sent to brain and info from brain is sent to body through____
important part of respiratory, digestive, and circulatory functions
bronchi - ANS-two short branches located at the lower end of the trachea that carry air
into the lungs.
bronchial network - ANS-extend into the lungs and terminate in millions of alveoli
Bulburethral/ Cowper's Gland - ANS-secrete a fluid into the urethra to neutralize the
acidity to the urethra
, calcium ions are released - ANS-when an action potential reaches a muscle fiber
capillary beds - ANS-diffusion sites for exchanges between blood and interstitial fluid
cardiac muscle tissue - ANS-involuntary muscle that is found only in the heart, cells are
striated
cardiac veins - ANS-collects deoxygenated blood from heart muscle tissue empty into
(coronary sinus) right atrium
cartilage - ANS-cushions and provides structural support for body parts
Caudal - ANS-toward the tail
cell - ANS-basic organizational unit of all living things
cell body - ANS-contains nucleus and other organelles
cell cycle - ANS-prices by which the cell reproduces, involves cell growth, duplication of
genetic material and cell division
cell differentiation - ANS-the process by which a cell becomes specialized for a specific
structure or function.
cell membrane - ANS-defines cell by acting as a barrier, helps keep cytoplasm in and
substances located outside of the cell out, also determines what is allowed to enter and
exit
Cell membrane (plasma membrane) - ANS-thin, semipermeable membrane of lipids and
proteins. isolates the cell from it's external environment while still enabling
communication w/ outside environment
centrioles - ANS-cylinder-shapes structures near the nucleus that are involved in
cellular division (occur in pairs)
centrosome - ANS-Pair of centrioles located at right angles to each other and
surrounded by protein, involved in mitosis and the cell cycle
