उत्तर
Lymphatic system is a network of organs, lymph nodes, lymph ducts and lymph vessels in the human body that make and move the lymph from tissues to the bloodstream.
Following are the functions of the lymphatic system:
- It collects and transports tissue fluid from the intercellular spaces in all the tissues, back to the veins in the blood stream.
- Lymph nodes play an important role in the defence mechanism of the body by killing the germs with the help of lymphocytes present in the lymph nodes and by making antibodies.
- They transport larger compounds like enzymes and hormones from their manufactured sites to the bloodstream.
