Define lymphatic system?

The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials. It includes lymph nodes, lymph vessels, lymphatic organs (such as the spleen and thymus), and lymphatic tissues (such as tonsils and adenoids). The primary function of the lymphatic system is to transport lymph, a fluid containing white blood cells, throughout the body to help fight infection and disease.

The lymphatic system is a network of tissues and organs that helps rid the body of waste and toxins, plays a role in the immune response, and maintains fluid balance. It consists of:

Lymph: A clear fluid that circulates throughout the body, collecting waste products from cells and tissues.

Lymph Nodes: Small, bean-shaped organs that filter lymph, destroying bacteria, viruses, and other foreign substances.

Lymph Vessels and Capillaries: A network of vessels that carry lymph throughout the body to the lymph nodes.

Lymph Ducts: Larger vessels that collect lymph from lymph nodes and drain it into the bloodstream.

Lymph Organs: Primary and secondary lymphoid organs, such as the spleen, thymus, and tonsils, which produce and store immune cells and antibodies.

Functions of the Lymphatic System:

- Drains and filters lymph: Removes waste products, bacteria, and other harmful substances from the body.
- Immune defense: Produces immune cells (lymphocytes) that fight infection and disease.
- Fluid balance: Helps regulate the balance of fluids and proteins in the body.
- Fat absorption: Absorbs and transports fatty acids from the digestive tract.
