Air is drawn down into the lungs as there is positive pressure in the lungs
What is the name of the volume of air inhaled with each breath
vital capacity
residual volume
peak flow
Tidal volume
Where is the control center for regulating breathing
The medulla oblongata and the pons in the brain
Hypothalmus and anterior pituitary gland in the brain
The cerebral cortex and posterior in the brain
Which of the following are involved in the regulating of breathing?
The medulla regulates the rate and depth of breathing in response to pH changes in the cerebrospinal fluid
The medulla adjusts breathing rate and depth to match metabolic demands
The pons regulates the tempo
Sensors in the aorta and carotid arteries monitor O2 and CO2 concentrations in the blood
These sensors exert secondary control over breathing
All of them
Describe the pressure in the lungs relative to the pressure in the alveoli
high partial pressure of of O2 to high partial pressure of CO2
high partial pressure of O2 to high partial pressure of CO2
In tissue capillaries, partial pressure gradients favor diffusion of O2 into the interstitial fluids and CO2 into the blood
hemoglobin, blood plasma, binds to the ..... which diffuses into the blood
CO2
N
Unicellular organism can exchange material directly with their envrionment

Distribution of substances and digestion in simple animals take place in 2 different cavities
Describe the three basic characteristics of open or closes circulatory system
They have 4 chambers to the heart
A set of tubes (blood vessels)
A muscular pump (the heart)
Blood can be mixed
A circulatory fluid (blood or hemolymph)
Blood covers the organs directly in an open circulatory of which organism
insects other arthropods and most molluscs
birds, reptiles and fish
mammals
The general bodily fluid mixture of blood and interstitial fluid, of open circulatory systems is known as Hemaglobin
Which of the following is not considered a function of an open system
Blood flows in vessels under high pressure
Open in to common cavities called hemocoel
Few blood vessels, but not extensive
Exchange of material between cells and blood (or hemolymph) is direct
Describe which of the following doesn't describe the function of an closed circulartory system organsim
Blood is confined to vessels and is distinct from the interstitial fluid
Material enters and exits via the blood vessels
The blood vessels have thin walls
Blood transport is efficient as it flows blood at high pressure
Blood vessels are branched into fine capillaries which are involved in the exchange of materials
Earth worms have 3 auxillary heart pumps which pump blood down to 2 ventral vessels
All of the following describe an open circulatory system: Little or no pressure (heart) Slower circulation (body movements) Little control of flow direction More direct exchange
All of the following describe a closed circulatory system: Higher pressure (heart, arteries) Faster circulation Precise control of path of blood flow Faster exchange

In the cardiac cycle the relaxing of the muscles is called the systole
The stroke volume is the
Amount of blood pumped in a 60 contraction
Amount of blood pumped in a single contraction
Amount of blood pumped without a single contraction
The cardiac output is the volume of blood pumped into the systemic circulation per minute and depends on both the heart rate and stroke volume
Arteries have a thicker wall than the veins... Why?
to accommedated for the higher pressure of blood being pumped around the body
the lumen is large
high pressure in the vessel could lead to a rupture in the thinner vein
the blood is only moving in one direction
The contraction of smooth muscle in arteriole walls; it increases blood pressure is known as
Vasodilation
Vasoconstriction
The relaxation of smooth muscles in the arterioles; it causes blood pressure to fall is know as
