Lymphatic System ft. Kenny G
Bristen, Alexa, JJ, Blake
What is the lymphatic system?
The lymphatic system is a system in your body that drains fluids/waste from tissue.
Major organs in the system
Parts
• Lymph nodes
• Spleen
•Tonsils
•Thymus
•Lymph Vessels
Function/Benefit
•Filters for immune system
•Purifies blood
•Fights infections
•Provides several hormones - matures white blood cells
•Able to transport and pick up fluids that leak in the tissue
Functions
Lymphatic system: Removal of fluid from the tissue/waste.
Spleen: Creates antibodies and filters blood.
Thymus: Location where white blood cells mature
Lymph nodes: Filters for the immune system
Tonsils: First line of defence against infections
Lymphatic vessels: Carry lymph to veins
Cause and Symptoms
Cause:
Hodgkin: Cancer that damages the white blood cells
Lymphedema: Swelling of the limbs. This is caused when the lymph fluid is retained or not flowing right.
Elephantiasis: A variety of diseases where parts of the body swell to massive proportions.
Symptoms:
Itchy skin, night sweats, weight loss, and enlarged spleen.
Swelling, aches and pains, and skin discolorations.
Difficulty walking, thickened skin, inability to care for one’s self, and pain.
The spleen
The Spleen is located in the upper left abdomen behind the ribs. The spleen is the largest lymphatic organ in the body. It’s purpose is to purify the bodies blood by making the red blood cells cycle into the spleen. When a cell can’t pass the “test” the spleen breaks down the cells using Macrophages. Macrophages are large white blood cells specialized for breaking down unhealthy red blood cells. Your spleen also helps the immune system by detecting unwelcomed microorganism like bacteria or a virus. You can live without your spleen, the liver and lymph nodes will take its job. Although, you are more vulnerable to infections.
Tonsils
Tonsils are clumps of tissue on both sides on the throat towards the back that helps fight infections. They trap the bacteria and viruses that enter the body through the mouth or nose, they also produce antibodies against diseases such as, polio, streptococcal pneumonia, influenza, and other infections. Some people have to get their tonsils removed because of Tonsillitis (the swelling of the tonsils) happening too often. Tonsillitis occurs when bacteria and other small organisms cause inflammation to the tissue. This results in fever, difficulty swallowing, sore throat, ear pain, loss of voice, difficulty breathing, and throat tenderness.
Tonsils
Thymus
The Thymus is an organ that matures T cells
(T lymphocytes ) by taking immature T cells from your bone marrow. T lymphocytes are specialized white blood cells that circle around our bodies and look for abnormal cells and infections.
Lymph nodes
The lymph nodes are basically the filter for the lymph system. It cleans out all the harmful bacteria and viruses.They can vary in size from a sesame seed to the size of a grape. You can have around 500-1500 Lymph nodes in your body.
Lymphatic vessels
Lymphatic vessels are thin walled,valved structures that carry lymph. The vessels carry lymph into veins. These vessels are storage for plasma. Without functioning lymph vessels, edema (swelling) will occur. The two types of vessels, afferent and efferent. Afferent carries lymph to lymph nodes. Efferent carries lymph from lymph nodes to the veins.
Explain how all of these body parts work together?
Why is the lymphatic system important to the body?
Working in the path
1-Spleen
2-Lymph nodes
3-Tonsils
4-Lymph vessels
5-Thymus
Cooperation
Cardiovascular System: Provides tissue and needed oxygen, nutrients, and the hormone- rich blood helping with the movement/ function.
Lymphatic System: Picks up fluid in the tissue and disposes of waste. With this it fights infections. Also helps with function.
How are these systems alike?
