Lymphatic System | Multiple Choice Questions | By Dr. Rakesh Ray

Our Queries:-

The lymphatic system is a network of vessels and organs that plays a crucial role in the immune system and fluid balance. It collects excess fluid from tissues, filters it, and returns it to the bloodstream. Additionally, it produces and releases lymphocytes, a type of white blood cell that helps fight infections.
Here's a more detailed breakdown of the lymphatic system and its functions:
1. Structure:
Lymphatic Vessels:
These are thin-walled tubes that carry a fluid called lymph, which is similar to blood plasma but with fewer proteins and more white blood cells.
Lymph Nodes:
These are small, bean-shaped organs that filter lymph and trap bacteria, viruses, and other foreign substances.
Lymphoid Organs:
These include the spleen, thymus, tonsils, and bone marrow, which produce and store immune cells.
Lymph:
This is the fluid that travels through the lymphatic vessels, carrying waste products, proteins, and immune cells.
2. Functions:
Fluid Balance:
The lymphatic system collects excess fluid (interstitial fluid) that leaks from capillaries into the tissues, preventing tissue swelling (edema).
Immune Defense:
Lymph nodes and lymphoid organs contain immune cells that filter lymph and initiate immune responses when foreign substances are detected.
Fat Absorption:
The lymphatic system absorbs dietary fats and fat-soluble vitamins from the small intestine and transports them to the bloodstream.
Waste Removal:
The lymphatic system helps remove waste products and toxins from the tissues.
Immune Cell Production:
The lymphatic system produces and stores lymphocytes, which are essential for fighting infections and other diseases.
