In capillary beds, the net inward pressure at the venular ends of the capillaries is less than the net outward pressure at the arteriolar ends of the capillaries. What is the result of this difference in pressures?Multiple ChoiceLymphatic vessels push fluid into the capillaries.More fluid flows into the capillaries than moves out.More fluid leaves the capillaries than returns.Pressure in the venules increases.

Why does fluid leave capillaries at their arteriolar end and enter at the venular end?Multiple ChoiceHydrostatic pressure is lower than osmotic pressure at the arteriolar end and higher at the venular end.Hydrostatic pressure is higher than osmotic pressure at the arteriolar end and lower at the venular end.

Regarding fluid movement through the capillaries,Multiple Choiceblood usually has a greater osmotic pressure than interstitial fluid.All of the choices are correct.blood pressure moves fluid out of the capillaries.nine-tenths of the fluid that leaves the capillary reenters the capillary.osmotic pressure moves fluid into the capillaries.

Describe the structural changes from arteries to arterioles, capillaries,venules and then to veins. Why are the walls of capillaries so thin?

Why does blood move slower in the capillaries compared to the arterioles?Multiple ChoiceCapillaries are much wider than arterioles.Blood pressure is much higher in capillaries than in arterioles.There are many more capillaries than arterioles.Precapillary sphincters close shunting blood into capillaries.

Which of the following is not a true comparison between lymphatic capillaries and blood capillaries? A. Lymphatic capillaries have mini valves that allow fluid to only flow into the vessels that are absent in blood capillaries B. Lymphatic capillaries have thicker walls than blood capillaries C. Lymphatic capillaries have larger diameters than blood capillaries D. Lymphatic capillaries originate as pockets rather than the continuous tubes of blood capillaries
