GENERAL HISTOLOGY

Detailed explanation-1: -Some of the tissue fluid re-enters the capillary from the venule end via osmosis. The tissue fluid loses most of its oxygen and other nutrients to the cells but has gained carbon dioxide and waste materials. Excess tissue fluid is drained into the lymphatic system and then back into the circulatory system.

Detailed explanation-2: -The tissue fluid surrounds the body cells, facilitating the exchange of nutrients and waste materials. At the venous end of the capillaries, the tissue fluid is drawn into the capillaries by osmosis.

Detailed explanation-3: -Water moves across capillary walls both by diffusion (osmosis) and by bulk flow.

Detailed explanation-4: -The lymphatic system is a network of delicate tubes throughout the body. It drains fluid (called lymph) that has leaked from the blood vessels into the tissues and empties it back into the bloodstream via the lymph nodes.
