Study Notes
Lymphatic System and Body Defenses
- The lymphatic system is crucial for fluid balance and immunity
- Lymph capillaries absorb interstitial fluid and return it to the blood
- Lymph nodes filter lymph, trapping pathogens and immune cells
- The spleen filters blood, removing old red blood cells and pathogens
- The thymus is vital for T cell maturation, crucial for an adaptive immune response
- Peyer's patches are located in the small intestine and help filter pathogens
- Tonsils filter pathogens entering the throat
- Lymphatic collecting vessels, small vessels that transport lymph, return lymph to the blood.
- Lymph capillaries have flap-like mini valves to prevent backflow, are characterized by the presence of flap-like mini valves, and consistently operate under high pressure.
- Lymph nodes are located along lymphatic vessels and filter lymph
