Lymph Nodes
Lymphatic system, especially in the nodes (lymph glands)
THE cells
Lymphatic circulatory
closed circulatory system!! blood fluid is DISTINCT from the body cells
a closed circulatory system
diffusion using capillaries and tissue fluid
Blood is the fluid portion of the circulatory system.
Macrophages
You have five litres of blood in your circulatory system. It contains 3 litres of fluid and 2 litres of cells, including red blood cells. It is the dynamic system. From the proximal end of the capillaries fluid is leaked out to interstitial compartment. The same amount of fluid comes back through the distal end of the capillaries. This interstitial fluid comes in close contact with each and every body cell, that is living. You have 11 litres of interstitial fluid in your body. Little in talked about this fluid, which does the important job of supplying the oxygen and nutrients to the cells. On way back to the circulatory system ,this fluid takes back the carbon bi oxide and waste products of metabolism.
This occurs when dead pancreatic tissue, blood, white blood cells, enzymes, and fluid that has leaked from the circulatory system accumulates.
Normal pericardial fluid is clear to straw colored. During pathological examination normal pericardial fluid does not contain blood, cancer cells, or bacteria.
