Lymphatic/ Immune System by:Loraene Lozano Pd:1
Major functions of the
Lymphatic & Immune systems
The Lymphatic system helps the body get rid of unwanted materials such as waste. Transport fluid (lymph) that contain white blood cells throughout the body
The Immune system removes excess fluid from the body tissue, absorb fatty acid, and also white blood cells seek out and destroy any disease causing cells or material
Anatomy of the lymphatic system
Helps maintain fluid balance in the body by collecting excess fluid from tissues and depositing them in the bloodstream. The lymphatic capillaries pick up fluid that gets into tissue and return it back to the heart. The lymph nodes have vessels connected to them so the nodes job is to filter the lymph (fluid). A diffuse system of small concentrations of lymphoid tissue found in submucosal membrane sites of the body, The spleen is to clear out worn or old red blood cells and any other foreign substances. The thymus is the main organ of the system it produces the T cells and once they are ready they leave and do their job.
Innate/natural immune defenses and Adaptive/acquired immune defenses;
This is the first defense it includes barriers such as skin, mucus, and chemical responses. Also this defense have cells such as macrophages, can kill and digest bacteria and parasites, as well as secrete cytokine
B and T cells are the main focus in this defense. These cells are able to recognize foreign substance and invading cell and are made to call and fight these type of issues. In this defense a lot of the new pathogens found are ready to fight and know what to do because it encountered this antigen before .
humoral vs. cellular response;
Is a response that involves with B cells. The B cells recognize pathogens and antigens that are in the lymph or blood. The helper T cells help the B cells go in plasma B cells so it can produce antibodies to different antigens.
Is a response that involves with T cells and responds to any cells that display MHC on its surface. It can occur inside effected cells.
antigens and antibodies
Antigens are toxin or any foreign substance that binds to any antibody
Antibodies are a blood protein that response to specific antigens. The antigens are produced from plasma cells
Disorders of the Immune system.
Type 1 Diabetes
The Immune system attacks the cells that produce insulin
It can cause swelling and deforms the joints
Can attack the tissue, kidney, lungs, and skin.
Immune deficiency that occur at birth
Viral infection that kills white blood cells and weaken the immune system.
