The Lymphatic System

Lymphatic System Organs and Their Functions

What is included in the Lymphatic system?

The lymphatic system has 6 major organs/parts. These

are the lymph vessels, lymph nodes, tonsils, thymus,

adenoids, and the spleen. The lymph vessels collect lymph

that has leaked from the blood vessels, and pump it

upward to be returned to the blood. The lymph nodes filter

lymph and produce and store cells that fight infection and

disease. Tonsils are oval-shaped pads of tissue that

sample bacteria and are the "body's first line of defense",

according to the American Academy of Otolaryngology.

The thymus stores specialized white blood cells and

prepares them to become T cells(cells who help destroy

infected cells). The adenoids trap germs entering through

the nose and mouth, and the spleen creates white blood

cells in the body while filtering the blood.

Lymphatic System Functions

The Lymphatic System Functions

The lymphatic system is in control of keeping your body clean as well as fighting unknown diseases or sicknesses in the body. Platelets are stored in the spleen, and are used to form clots in the body to stop blood from bleeding excessively, which keeps your body cleaner. The tonsils block germs entering from the nose or mouth, and regulate the amount of germs and bacteria that enter the system. Tonsils contain many white blood cells to protect the body from germs. This helps it fight diseases. The lymphatic system is like your body's drainage system and cleans up waste left behind by other systems. Lymph flows through the body constantly and gets pumped through lymph vessels by muscles. Lymph fluid depends on muscles to carry it around the body and let it rejoin the blood.

The lymphatic system cleans up waste left behind by other systems. When blood vessels leak, then the fluid that has leaked is collected in the space between cells and tissues. After the fluid collects, it is picked up by lymph vessels, and the fluid is renamed "lymph". The lymph vessels slowly push the lymph upward with the squeezing of the skeletal and smooth muscles. Eventually, the fluid is returned to the cardiovascular system.

Interactions with Other Systems

What other systems interact with the Lymphatic System?

The lymphatic system interacts with the circulatory system to return body fluids to the blood. When lymph leaks from the blood vessels, it is caught in the space between the cells and tissues, and then picked up by the lymph vessels. The lymph is then slowly returned to the circulatory system with the squeezing of smooth and skeletal muscles.

The lymphatic system also works with the digestive system when dietary lipids leak from the digestive system are caught by lymphatic vessels. They use lymphatic vessels for transportation through the body and back to the digestive system. They go through the lymphatic system instead of the blood vessels.

Interesting Facts

Interesting Facts

Lymph is a clear fluid containing white blood cells. The word "lymph" came from the Latin word "lympha", which meant "connected to the water. Also, lymph only flows upward toward the neck, but never downward. It needs to move upward because subclavian veins are near the neck, and the subclavian veins are where the lymph needs to go to re-enter the blood. The lymphatic system does not have a central pump, it moves lymph around by the squeezing of smooth and skeletal muscles. Lastly, white blood cells are found in the spleen, which is the largest organ in the lymphatic system.

Tonsillitis

-Audrey

One disease of the lymphatic system-tonsillitis

Tonsillitis is a disease where your tonsils are inflamed. It is often

caused by common viruses, however it can also be caused by

bacterial infections, like strep throat. Tonsils get infected because

they sample germs entering the body, and they are the first ones

to be exposed to the germs, so they are at risk of being infected.

Some signs and symptoms of tonsillitis are red and swollen

tonsils, white or yellow coating/patches on the tonsils, sore throat,

difficult or painful swallowing, fever, enlarged and tender lymph

nodes in the neck, a scratched, muffled, or throaty voice, bad

breath, stomachache (particularly in younger children), stiff neck,

or headache. If left untreated, tonsillitis can affect the digestive and respiratory systems, give you difficulty breathing, disrupted breathing during sleep, infections such as tonsillar cellulitis and peritonsillar abscess, and disorders such as rheumatic fever and poststreptococcal glomerulonephritis. Doctors will diagnose tonsillitis by looking at your throat, ears, and nose, checking for scarlatina, checking if you have swollen lymph nodes, listening to your breathing with a stethoscope, checking for enlargement of the spleen, doing a throat swab, and doing a CBC (complete blood cell count). Tonsillitis can be treated at home with encouraged rest, adequate fluids, comforting foods and beverages, saltwater gargles, humidified air, lozenges, avoiding irritants, and treating pain and fever. If tonsillitis was caused by a bacterial infection, then your doctor will prescribe an antibiotics course, such as penicillin taken orally for 10 days. If the treatment does not work, then a surgery to remove the tonsils will be performed.

Lymphoma

-Sienna

About Lymphoma

Lymphoma is a type of cancer that starts in infection-fighting cells of the immune system, which are called lymphocytes. These cells are in the lymph nodes, spleen, thymus, bone marrow, and other parts in the human body. If a person has lymphoma, lymphocytes change and grow out of control. However, the side effects are shortness of breath, coughing, itching, having a fever, night sweats, weight loss, swollen glands (lymph nodes), often in the neck, armpit, or groin that are painless. Your doctor will diagnose lymphoma by asking how you have been feeling, when did you first notice changes, how is your appetite, have you lost any weight, do you feel tired or weak, what are your current medical problems and treatments, and what is your family medical history. The treatment for Lymphoma depends on the type and stage. Lymphoma treatments include; Active surveillance, Chemotherapy, Radiation therapy, and Bone marrow transplant.

Lymphadenitis

-Jaedon

Lymphadenitis treatments

Lymphadenitis

-use injection or antibiotics to fight bacteria

-medicine to reduce pain, fever, swelling

-surgery

Lymphadenitis is an infection in the lymphatic system causing the lymph nodes to swell. Lymphadenitis can happen when a disease flows through the bloodstream and the lymph nodes get infected by the lymph flowing with the blood cells. Swelling or inflammation in the lymph nodes are usually caused by a common cold or a cough. Lymph nodes are found in most parts of the body.
