Question:
What are the small ovoid structures which occur along lymphatic vessels?
a) The lymph nodes
b) The spleens
c) The tonsils
d) The thymus glands
e) The Peyer patches
Waste Materials Carried by Lymph
The lymph carries multiple waste materials that are removed from the blood vessels and are taken up by the lymph at the capillary region. These waste materials can have a serious threat to the body cells which is why they are prevented from getting accumulated in the tissues. The waste materials are carried to a specific region so that all the residual components are removed from the body.
