Fill in the blank with the right words for all three sentences. Word bank Higher, same, lower. Are some words used twice?
Hydrostatic pressure in the capillaries at the arteriole end is _______ than at the venous end.
The volume of fluid that returns to capillaries at the venous end is __________than the amount that left capillaries at the arteriole end.
Osmotic pressure in the capillaries at the arteriole end is ____________ than at the venous end.
1) Hydrostatic Pressure:
Hydrostatic pressure is the pressure exerted by a fluid, in this case, blood, against the walls of the capillaries.
At the arteriole end of the capillaries, the pressure is higher because this is where blood is being pumped into the capillaries from larger arteries. This higher pressure helps to force fluids, along with nutrients and oxygen, out of the capillaries and into the surrounding tissues.
At the venous end, the pressure is lower because blood has passed through the capillaries, nutrients and oxygen have been delivered to the tissues, and some fluid has been lost to the tissues. Blood is returning to the veins at a reduced pressure.
2) Volume of Fluid:
The volume of fluid refers to the amount of blood or plasma that leaves the capillaries at the arteriole end and returns at the venous end.
At the venous end, the volume of fluid that returns is lower than the amount that left at the arteriole end. This is due to the fact that some fluid, along with nutrients and oxygen, has been delivered to the tissues at the arteriole end. Additionally, some of the fluid has been absorbed into the tissues and will eventually re-enter the circulatory system via the lymphatic system.
