3 areas of the brain - CORRECT ANSWER: cerebrum
cerebellum
medulla (brain stem)
3 types of muscle - CORRECT ANSWER: cardiac
smooth
skeletal
3 types of neurons - CORRECT ANSWER: sensory
interneurons
motor neurons
accessory organs - CORRECT ANSWER: In the GI tract, organs that play a role in
digestion but not directly part of the alimentary canal.
These include the liver, the gallbladder, the pancreas
adrenal gland (funct, hormones assoc.) - CORRECT ANSWER: on the kidneys
fight or flight hormone
regulate water balance, BP and joint articulation
,adrenaline steroids (cortisone)
aerobic respiration - CORRECT ANSWER: Respiration that requires oxygen,
sequentially releasing energy and storing it in ATP
glucose is used to obtain energy
OPPOSITE of photosynthesis
aerobic respiration begins at the __ and ends at the __ - CORRECT ANSWER:
cytoplasm and ends in the mitochondria
after absorption, products of digestion goes to - CORRECT ANSWER: blood and lymph
alimentary canal - CORRECT ANSWER: Also known as the gastrointestinal (GI) tract of
the digestive tract, the alimentary canal is the long muscular "tube" that includes the
mouth esophagus, somatch, small intesitne, and large intestine.
carries out stages of digestive process (mechanical and chemical digestion and absorb
ion)
alveoli - CORRECT ANSWER: tiny sacs of lung tissue specialized for the movement of
gases between air and blood
amylase - CORRECT ANSWER: enzyme in saliva that breaks the chemical bonds in
starches
anaerobic respiration - CORRECT ANSWER: Respiration in the absence of oxygen.
This produces lactic acid
less efficient
,anus - CORRECT ANSWER: A muscular opening at the end of the rectum through
which waste material is eliminated from the body
appendicular skeleton - CORRECT ANSWER: limbs of body
ateries - CORRECT ANSWER: transport blood away from the heart
muscular (carry blood at high pressures)
atrioventricular valve - CORRECT ANSWER: either of two heart valves through which
blood flows from the atria to the ventricles
atrium - CORRECT ANSWER: upper chamber of the heart that receives and holds
blood that is about to enter the ventricle
autonomic PNS - CORRECT ANSWER: This nervous system provides involuntary
control over smooth muscle, cardiac muscle, and glands.
external environment
axial skeleton - CORRECT ANSWER: trunk of body
axon - CORRECT ANSWER: the extension of a neuron, ending in branching terminal
fibers, through which messages pass to other neurons or to muscles or glands.
axon terminal - CORRECT ANSWER: The endpoint of a neuron where
neurotransmitters are stored.
, bile - CORRECT ANSWER: a mixture of salts and phospholipids that aids in the
breakdown of fat
blood - CORRECT ANSWER: type of connective tissue that is made up of a variety of
cells suspended in liquid called plasma
blood of embryo and mother are - CORRECT ANSWER: never directly connected
blood vessel function in bones - CORRECT ANSWER: provide nutrients and oxygen
take away wastes
brain - CORRECT ANSWER: located in the skull and controls most functions in the
body
brain stem includes - CORRECT ANSWER: medulla oblongata and pons and midbrain
and parts of the hypothalamus
bronchi - CORRECT ANSWER: The passages that branch from the trachea and direct
air into the lungs
bronchioles - CORRECT ANSWER: small subdivisions of the bronchi that are dead
ends with tiny air sacks called alveoli at the end
capillaries - CORRECT ANSWER: tiny blood vessels that connect arteries and veins
walls allow materials to enter and leave blood
carbohydrate (enzymes, end products and important locations) - CORRECT ANSWER:
1. amylase, sucrase, maltase
