Circulatory systems have the major benefit of overcoming the short fallings of . . .
the slow rate at which diffusion occurs across cells.
communication systems involving the nervous system
cushionging animals from trauma
temperature differences between lungs and other active tissues.
The fluid that moves around in the open circulatory system of a typical arthropod like an insect or crustacean is called . . .
digestive juices
blood plasma
interstitial fluid
hemolymph
To adjust blood pressure independently in the capillaries of the body and provide efficient exchange to support an endothermic life style an organsm would need. . .
an open circulatory system.
two chambered heart.
four chambered heart.

A portal system is a (an)
area connecting arterioles to venules.
a vessel connecting two capillary beds.
a series of arteries that return blood to the heart in an open circulatory system.
a space where blood can pool in an open circulatory system.
Which of the following develops the greatest pressure on the blood in the mammalian aorta?
systole of the left ventricle
diastole of the left atrium
systole of the left atrium
diastole of the right atrium
Damage to the sinoatrial node (SA node) in humans would . . .
block conductance between the bundle branches and the hypothalamus.
contribute to high blood pressure and strokes.
disrupt the rate and timing of cardic muscle contractions.
influence the blood pressure in the inferior aorta.
A stroke volume of 70ml/cycle, and a pulse of 72 beats(aka cycles) per minute results in a cardiac output of . . .(watch units here)
approximately 5 L/min
504 ml/min

The material present in arterioles that is not present in capillaries is. . .
white blood cells
plasma
endothelial cell lining.
smooth muscle lining that can alter the diameter.
An increase in nitric oxide within a vascular bed is associated with . . .
vasoconstriction
vasodilation
hardening of the arteries
reduction of blood flow to that area
Swollen areas in the neck, armpits, and groin are associated with . . .
sodium depletion
dehydration
increased activity in the immune system
unusually high blood sugar
The velocity of blood flow is lowest in the capillaries which allow exchange to occur because. . .
The capillary walls are not thin enough to allow oxygen to diffuse.
The capillaries are the furthest vessel from the heart.
The total cross sectional area of the capillaries is largest of all other vessels.
Blood pressure is too high to deliver blood to the capillaries at a fast rate.
Fluid is filtered out of a capillary bed at the arteriole end because...
the hydrostatic pressure of the blood is greater than the osmotic pressure of the blood.
the osmotic pressure of the blood is greater that the hydrostatic pressure of hemolymph.
the osmotic pressure of interstitial flid is great than that of the blood.
The hydrostatic pressure of the blood is equal to the osmotic pressure of the blood.
What are the effect of long term blocking of lymphatic vessels associated with a capillary bed?
Swelling and accumulation of more interstitial fluid.
More fluid entering the venule.
The area blocked becomes smaller.
Large proteins leaking out of the blood into the interstitial fluid.
Large proteins such as albumin remain in capillaries rather than diffusing out resulting in the . . .
Increased diffusion of hemoglobin (Hb).
Development of an osmotic pressure difference across the capillary bed.
Loss of fluid from the arteries.
Increased diffusion of carbon dioxide.
