Summary Introduction
Introduction:
The lymphatic system is a part of the immune system and the circulatory system. It consists of the components, such as the lymphatic organs, vessels, and tissues. It consists of lymph, which flows throughout the body via the lymphatic vessels. The lymphatic system maintains the blood composition and volume, and also transport immune cells (lymphocytes) in the body.

Lymph collected from the lower abdomen, pelvis, and lower limbs is carried by the: (a) right lymphatic duct. (b) inguinal duct. (c) thoracic duct. (d) aorta.
Which part of the body does the thoracic duct not drain lymph from? (a) the left side of the neck, (b) both the lower limbs, (c) both the upper limbs, (d) the left half of the head.
(a)
The lymphatic system is a part of the circulatory system and a vital part of the immune
system. It is a network of tubes throughout the body that drains fluid (called lymph)
from tissues and empties it back into the bloodstream.
(i)
Give a brief explanation why the lymphatic system is a one-way system,
whereas the blood vascular system is a two-way system.
(ii)
Point out TWO (2) type of infections that may cause the lymph nodes to swell.
