Transcript of The Human Body

The Immune System How It Works The main function of the Immune system is to protect the human body. The immune system creates a barrier to protect against bacteria and viruses from entering your body.
If any bacteria or viruses manage to get into the body, the immune system tracks them down and eliminates them before they have a chance to reproduce or proliferate.
Once the body has detected these bacteria and viruses, it knows how to defend against them so they wont affect the body more than once.
If the bacteria and viruses manage to go undetected, the immune system works to eliminate the reproduced cells.
Other than bacteria and viruses, the immune system also works to eliminate cancerous or other unwanted cells.
The immune system is involved with the healing response to trauma as a protection against infection. How It Interacts With Other Systems The immune system only works with the circulatory system.
The main way of getting around for immune cells are the blood vessels.
Which the where the circulatory system allows immune cells to travel throughout the blood vessels in the body and survey for infection.
When the body has an infection or virus, the circulatory system spreads the immune cells through the body.
The immune system then stops this by sending white blood cells to the place where the infection or any virus cells is.
The immune cells travel through the blood stream to heal the infection or the virus.
The immune system sends white blood cells to the circulatory system to help protect from germs bacteria viruses. Medical Problems Associated With It Multiple sclerosis is medical problem that is caused by damage to the myelin sheath. When this nerve covering is damaged, nerve signals slow down or stop. The nerve damage is caused by inflammation. Symptoms are loss of balance, vision problems, numbness, tingling, or pain and trouble speaking.
Lupus is a disease in which the bodies own immune system mistakenly attacks healthy tissue. Because of this the body could have inflammation. Some symptoms could be Chest pain when taking a deep breath, fatigue, fever with no other cause, general discomfort, uneasiness, or ill.
Fibromyalgia is a condition in which a person has long-term, body-wide pain and tenderness in the joints, muscles, tendons, and other soft tissues. Some symptoms include tender points which are found in the soft tissue on the shoulders, chest, lower back, and hips. The Main Components Bone Marrow is a tissue that through a process of hematopoiesis creates stem cells. These stem cells sort out to different blood and lymphatic cells and get released in response to hormones.
Thymus, a small organ, isn't very well heard due to the fact that it's useless after you mature. The thymus matures the thymocytes into T cells which later on manage the immune system by telling other cells how to react to foreign substances.
The spleen filters blood and rejuvenates blood vessels. It also contains specialized cells like the T and B cells. The T cells instruct B cells to create antibodies against foreign substances.
Lymph nodes filter lymph which is a substance which contains fluids dropped by tissues. This substance is then returned to your blood for circulation where unnecessary microorganisms enter the liquid. Lymph contains the same cells in the spleen so it's able to respond accordingly. References
