step 2 krebs cycle
carbon dioxide, NADH
step 3 electron transport chain
NADH , ATP
which steps take place in mitochondria?
2 and 3
which step froms the most ATP?
What is the effect of temperature on respiration (glucose metabolism)?
increase rate of reproduction because cellular respiration increases (bark beetle example)

yes after puberty
what is the male hormone?
enviornmental tobacco smoke
second hand smoke and exhaled smoke
large number of chemicals in tobacco smoke
nicotine, tar, carbon monoxide
why does second hand smoke contain more carbon monoxide?
higher concentrations of toxic chemicals are present
pathway of air from enviornment to blood in the body
what is the function of cilia located in the trachea?
stop lung damage, sweeps away bacteria through saliva
What effect does smoking have on the cilia?
lungs contain alveoli...they are sacs of what?
are the sites of gas exchange with blood capillaries
when the diaphram contracts what happens to the pressure and air movement?
When the disphragm relaxes what happens to pressure and air movement?
push air out of lungs
What are the characteristics of a health lung?
pink, alveoli makes lungs spongy
large irregular air sacs/shrinking blood sacs
What happens during emphysema?
damage to lungs and air sacs/harder to breathe

42% in one year, 5 years 16%
blood is comprised of
platelets, plasma, and cells
red and white cells
trigger blood clotting. needs proteins

whch chamber recieves oxygen rich blood?
which chamber recieves oxygen poor blood?
which chamber sends blood to the whole body?
which chamber sends blood to the lungs?
any vessel that carries blood AWAY from heart
carries blood TOWARD the heart
oxygen exchange in lungs and body. exhange of waste such as carbon dioxide and urea
How do lungs get rid of carbon dioxide?
central nervous system
spinal cord, brain
peripheral nervouse system
connect to CNS
recieve sensory receptors
transfer and interpret impulses
control of muscles and glands
impulses/intructions to muscles and glands
cells of nervous system
neurons and Glia
non neuronal cells
Neuron Components- dentrites
branched projections of a neuron
neuron components- cell body
protoplasmic protusions that extrude from the cell body of a neuron
N.C.- synapse between neurons
permits neurons to pass an electrical or chemical signal to another cell
what is the input part of a neuron?
what is the output part of a neuron?
what is action potentials?
short lasting event, electrical membrane potential of cell rapidly rises and falls
Where does action potentials occur?
excitable cells- neurons
