Describe the two types of pressures controlling fluid movement in a capillary bed. Explain the role of each pressure in fluid movement
What will be an ideal response?
Blood pressure forces fluids and solutes out of capillaries while osmotic pressure pulls fluid back into capillaries. Osmotic pressure is created by plasma proteins in the blood. At the arterial end of the capillary, blood pressure is higher than osmotic pressure, so fluids and solutes are pushed out of the capillary and into the interstitial space. As fluid is forced out of the capillary, blood pressure drops. Therefore, at the venous end of the capillary, osmotic pressure is higher than blood pressure so fluid is pulled back into the capillary from the interstitial space at the venous end.

1. When blood serum enters a lymph node it is called lymph. 2. It is easier for substances to move into a lymph node than into a blood capillary. 3. Lymph does not circulate through the lymph system the same way blood circulates through the circulatory system. 4. Thymosins are hormones released by the thymus gland, which influence the development of B lymphocytes. 5. The spleen can hold about 100 mL of blood.
