Is the immune system fully operational at birth?
No, it is not. This is why very young kids can have transplants and not require immunosuppresives in later life - their immune system adapts to accept a donor organ, because it's too young to reject it. The immune system becomes pretty much fully operational around 1 year old.
How the immune system works?
The immune system is run by white blood cells which attack any foriegn objects in the body. They grow stronger and begin to recognize sickness which allows you to become fully immune if you have a great immune system.
Why are Immunoglobulins important?
Without them, the body lacks a fully functioning immune system
If HIV is so weak that it cannot lead to immune system collapse then what is the cause of death among the HIV infected in south African blacks?
HIV cannot fully collapse your immune system, but it can come close. Reason this is a problem is we need the function of our immune system to fight off any disease even ones as simple as the common cold or flu. If you have a weak immune system such as people who have been diagnosed with AIDS (meaning a person cannot fight off simple infections), then even the common cold becomes deadly. So many south African blacks (or anyone) who are infected do not die from HIV, but other diseases that they acquire because of their weak immune systems.
How does making the immune system stronger lengthen the life of a person with AIDS?
IF the immune system is strengthened the person is less susceptible to obtaining infections like pneumonia which can cause death if they don't have a fully functioning immune system
What is the pourpose of an appendix?
It is considered as a vestigial structure.Its function was to house cellulose digesting bacteria in ancient human.But along with the evolution,appendix has lost bacteria in it. Appendix serves as a safe house for useful bacteria when a disease flushes the intestine
Which gland that is important in the immune system begins to atrophy during puberty?
The Thymus Gland. It grows slowly until puberty then fully develops thereafter.
Do most babies die from Swine Flu?
Not necessarily, babies are definatley a risk with swine flu being that their immune system has not fully matured so a flu shot might be an option if you are worried. Old people are also at a risk due to their dying immune system. In teen years you are most likely not going to die because of swine flu due to your strong immune system so they are not at a risk.
What accounts for the declining efficiency of the immune system with age?
The decline in the immune system with age is still an area of active investigation. A complete understanding of the molecular interactions and physiological mediators that being about this decline are not fully dissected as yet. However, the general consensus is that there is a gradual decline the in the size of the thymus beginning at around age 20 and extending for the rest of the individuals life. This is one major reason to account for the decline in the immune system with age
What does a strong base do in solution?
becomes fully ionized They dissociate fully / ionize fully into OH- ions.
What is a Toyota hiace vacuum pump for?
vacuum pump helps the brake system to function well when pedal is fully depressed and released.
How does the immune system work to prevent pathogens from causing disease in the body?
Not exactly, at least not the immune system most know.In the acquired immune system, a disease enters your body and starts making you feel ill. Your immune system can now destroy this disease because it is in you and it has sensed it. Sometimes diseases are sensed so quickly and the body is already ready for it (due to memory b-cells)that you never feel it. This often happens with the chicken poxs.However the innate immune system can completely prevent certain diseases. Your innate immune system is made up of your skin, your digestive track (primarily the stomach and its acid), and mucus membranes (like inside your nose and lungs). Those systems can block diseases and send them away before they fully enter the body (cool facts, the space in your lungs and your digestive system are not considered "inside the body" - that's right, there is basically a hole going right through your person.)
