discussed in terms of each category’s action of stopping the acute rejection. Acute rejection will also be researched in order to better understand which immunosuppressive drug will intervene the rejection process and where. The purpose of the immune system in comparison to the purpose of immunosuppressive drugs will be compared; the immunosuppressive drugs leave the body defenseless. However despite the downsides to immunosuppressive‚ emphasis will be shown to the importance of immunosuppressive

The disease is spread through the air from one person to another through coughing‚ sneezing‚ etc. It commonly is a pulmonary disease‚ attacking the lungs‚ but can also spread to a variety of other places such as the kidney or brain. It can remain latent for extended periods of time‚ surfacing when the immune system is compromised for a variety of reasons.

Pregnant women‚ children less than 5 years of age‚ and adults that are over 20 years of age are at the highest risk for this disease due to either their undeveloped immune system or their degenerating immune system as they age. Following this logic‚ people with compromised immune systems and comorbid diseases that fight the immune system‚ such as Leukemia and HIV infection‚ are highly prone to contracting Measles. Recently‚ data is showing that people who frequently visit countries such as the slum

They are often viruses‚ bacteria‚ or fungi‚ but can sometimes be dust‚ chemicals‚ pollen‚ or food proteins that cause allergic reactions. (Antigens that cause allergic reactions are called allergens). An epitope is the part of the antigen to which the antibody binds. Once the immune system has created and antibody for an antigen whose attack it has survived‚ it continues

infants and elderly people. This is due to infants immune systems not being fully developed and the elderly’s being weakened. Undeveloped or weak immune systems can’t contain the spread of the bacteria as well as a healthy one. A healthy immune response to tuberculosis would involve the body creating a wall around the bacteria. Then the body encases the surrounded bacteria in scar tissue to prevent the spread of the disease. These sac-like immune defense structures the body forms are known as tubercles

breastfeeding is a critical step in raising a healthy baby‚ because it develops a healthy immune system for the child‚ and it helps build bone structures. c. Main points: i. The immune system benefits from the breast milk. ii. Breastfeeding helps the development of bone structure in a baby. II. Infants are fragile and can catch a disease or infection quickly. Because their bodies and immune system are not fully developed‚ they must be treated with special care and given the right nourishment
