How does blood maintain homeostasis in the body?

Homeostasis is a self-regulatory process by which organisms maintains stable internal environment to their sustenance. In humans, blood plays an important role in maintaining homeostasis by performing many functions. Blood supplies oxygen, nutrients to the tissues and removes waste such as carbon dioxide, urea and lactic acid from cells. It circulates chemical messenger such as hormones to the target cells. It regulates body pH, body temperature and osmotic pressure of the blood.        

hey, what do you need . just post the question and i may be able to you : )

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
