The lymph system is designed for transportation in a way similar to the circulatory system, but it is not about oxygen and nutrients. The lymph fluid acts like the clean-up crew for your body.
You know that you are made of water and fluids. All of those fluids are usually contained inside cells- “intracellular”. There are some fluids found between the cells or actually seep out of the cells. This ”intercellular” fluid slowly begins to accumulate and must be returned to the cells and the blood stream. The lymph system gathers those fluids and returns them to your blood. The lymph system is also closely associated with your immune system.
Collect and transport fluids from the intercellular spaces in the tissues of the body, back to the veins in the blood system. It plays an important role in returning plasma proteins to the bloodstream
Digested fats are absorbed and transported from the villi in the small intestine to the bloodstream via the lacteals and lymph vessels.
3 . Lymphocytes are manufactured in the lymph nodes-
They filter out bacteria and toxins.
4. Transports large compounds like enzymes and hormones from their manufactured sites to the bloodstream.
Where are lymph nodes located?
between 500 and 600 lymph nodes distributed throughout the body. Found in clusters in the underarms, groin, neck, chest and abdomen.
Why are there so many?
Their function is to filter out all the dead bacteria, viruses, and other dead tissue from the lymphatic fluid and eliminate it from the body. When the immune system is activated they begin producing large numbers of lymphocytes which causes them to swell.
The tonsils (palatine tonsils) are a pair of soft tissue masses located at the rear of the throat (pharynx). Each tonsil is composed of tissue similar to lymph nodes.
How does this help the HCP during your exam?
2.03 Remember the stuctures of the lymphatic system
The thymus gland is an organ in the upper chest cavity that processes lymphocytes. This organ is part of both the lymphatic system and the endocrine system, which includes all glands that produce hormones.
