Lymph Notes

Overview of Lymph and Lymphatic System

• Lymphatic Vessels: Also known as lymphatics, they carry a watery fluid called lymph from body tissues.
• Lymph: Originates from blood vessels and is a fluid squeezed out of blood vessels.

Key Components of Lymphatic System

• Lymph Nodes: Filter lymph and help in activating the immune system.
• Lymphatic Circulation: Involves movement of lymph from capillaries to larger vessels and eventually back to the circulatory system.
• Lymphoid Organs: Include structures like the spleen, tonsils, bone marrow, and thymus which play roles in immune response.

Functions of the Lymphatic System

• Fluid Balance: Returns excess interstitial fluid to the bloodstream.
• Protection from Infections: Lymph nodes and organs filter pathogens and participate in immune responses.
• Transportation of Fats: Absorb and transport fats from the digestive system.
