What are the 2 general roles of the lymphatic system?
- 1. Circulatory role
- 2. Defence role
-
Give a note on the circulatory role of the lymphatic system (4p)?
- Returns the (small) proteins lost from capillaries.
- Returns fluid lost from capillaries, maintaining blood pressure and volume.
- Removes excess tissue fluid, preventing swelling (oedema).
- Collects lipids from small intestine and transfers to the blood via subclavian veins. (Fats travel by lymphatic not circulatory system- go by the lacteal).
-
What does the lymphatic system return?

-
What does removing excess tissue fluid prevent?

-
What does the lymphatic system collect and transfer to blood via subclavian veins?
Collects lipids from small intestine and transfers to the blood via subclavian veins.
-
Where are lipids collected from by the lymphatic system?
Collects lipids from small intestine and transfers to the blood via subclavian veins.
-
Give a note on the defence role of the lymphatic system (3p)?
- Removes bacteria, viruses, cancer cells, cell debris and toxins from the lymph by lymph nodes.
- Lymph nodes continuously monitor lymph fit infections and cancer.
- Lymphocytes and monocytes multiply in lymph nodes during an infection.
-
