The Lymphatic System

Overview : 

We all have a lymphatic system. The lymphatic system is very important to our body. It does many things to help it defend itself against illnesses and infections. The lymphatic system performs many functions to allow this to happen. It does this by using the organs and bodily functions they contain. Overview

What is the lymphatic system? : 

What is the lymphatic system? The lymphatic system is a network of very small vessels . It is used as an extensive drainage network. This drainage network helps to keep bodily fluid level in balance. This drainage network also defends the body against infections that are or will happen. The drainage network is made up of lymphatic vessels that carry lymph. Lymph is a clear, watery fluid that holds protein molecules, salts, glucose, urea, and other substances. The spleen, which is set in the upper left part of the abdomen under the rib cage, is the part of the lymphatic system that protects the body, clearing worn out red blood cells and other unknown bodies from the bloodstream to help fight off infections.

Why is the lymphatic system important? : 

Why is the lymphatic system important? One of the biggest jobs of the lymphatic systems is to accumulate extra lymph fluid from body tissues and send it back to the blood. This process is very risky because water, proteins, and other substances continuously leak out of tiny blood capillaries into the surrounding body tissues.

The lymphatic system also helps defend the body against germs like viruses, bacteria, and fungi that can cause sicknesses. Those germs are cleansed out in the lymph nodes. Lymph nodes are small masses of tissue located beside the network of lymph vessels. The lymph nodes' homes are the lymphocytes, which are a type of white blood cell. The spleen contains lymphocytes and another type of white blood cell called macrophages. The macrophages drown and eliminate bacteria, dead tissue, and unknown matter and remove them through the spleen. Some lymphocytes make antibodies, which are special proteins that fight germs and stop infections. They do this by trapping the disease-causing germs and kill them before they spread.

What is the process of the lymphatic system? : 

What is the process of the lymphatic system? One of the lymphatic system's major vessels is the thoraic duct. The thoracic duct starts near the lower part of the spine and gathers lymph nodes from the pelvis, abdomen, and lower chest. The thoracic goes up through the chest and empties into the blood which runs through the large vein near the left side of the neck. The right lymphatic duct is the other important lymphatic vessel that gathers lymph from the right side of the neck, chest, and arms. They then empty into a large vein near the right side of the neck.

To carry out waste, lymph fluids drain into lymph capillaries which are tiny vessels. Then the fluid is pushed along when a person breathes or when the muscles contract. The lymph capillaries are very thin. They have many tiny apertures that allow gases, water, and nutrients to go through to the surrounding cells, nourishing them and getting rid of waste products. If the lymphatic system didn't get rid of excess fluid from the tissues, the lymph fluid would amplify in the body's tissue. The result is the swelling of tissue. When lymph fluid leaks this way, it is called interstitial fluid.

Slide 8: 

The lymphatic lymph fluid comes in through the lymph nodes, which is also where macrophages fight off unknown bodies like bacteria, removing them from the bloodstream. After these substances are removed, the lymph fluid leaves the lymph nodes and returns them to the veins. There they re-enter the bloodstream and the process is repeated.
