Which forces affect the exchange of substances between blood and tissue fluid?
At the proximal end of capillary, you get the fluid out in the tissue fluid due to blood pressure. At the distal end of the capillary, you get back the tissue fluid due to oncotic pressure of the blood proteins.
How does the thick capillary wall help blood move slowly?
Capillaries do not vary in thickness, they are very thin. The thin wall permits the exchange between the blood in the capillary and the adjacent tissue cells.
What causes the transfer of materials between capillaries and tissue fluid?
As blood enters the capillary bed on the arteriole end, the blood pressure in the capillary vessel is greater than the osmotic pressure of the blood in the vessel. The net result is that fluid moves from the vessel to the body tissue.At the middle of the capillary bed, blood pressure in the vessel equals the osmotic pressure of the blood in the vessel. The net result is that fluid passes equally between the capillary vessel and the body tissue. Gasses, nutrients, and wastes are also exchanged at this point.On the venue end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel.
What blood vessel exchanges substances with a nephron?
Capillary. The thin walls allow diffusion of materials to pass from the blood flow into the nephron.
Which term refers to the movement of white blood cells between endothelial cells lining capillary walls to enter the tissue?
Diapedesis
What is granulation tissue composed of?
clotted blood, fibroblasts, & extensive capillary network
What is Function of the blood capillary?
The function of blood capillaries is to provide cellular, or tissue, respiration, provide nutrients and remove waste products. They are the tiny blood vessels that are between the venules and arterioles and the interstitial space between cells.
What kind of blood vessels bypass capillary bed in the tissue?
metarterioles when resistance is low
What is the function of the capillary muscle?
The only muscle that is a functional part of the capillary system are part of the pre-capillary sphincters. It is smooth muscle encircling the arterial end of a capillary and controls the blood flow. Not every cell is getting blood at every second for seconds at a time capillary can be shut of to direct blood to other parts of the tissue that need it.

All exchanges to and from the blood and tissue cells occur through the?
CAPILLARIES.
When performing a capillary stick what do you do with the first drop of blood?
The first drop of blood is wiped away because it is mainly just tissue.
