Why do humans need red blood cells?

Answer 1

blood is important to our bodies because it keeps us warm and our boodies have to be warm or we get hypothermia or even frostbite. but blood is most important because the hemoglobin in it carries the oxygen to our brainand organs.

Answer 2

Blood is an important part of the body. This is because it is primarily used for transporting oxygen to tissues in the body and removes carbon dioxide. Its also used for transporting hormones, nutrients and waste products. White blood cells are also found in the blood and these are used to fight infections. One of our research focus is on the study of processes involved in the formation of blood clots. While blood clots normally form to prevent excessive bleeding following an injury, the same process is responsible for the formation of harmful clots that may block blood vessels causing heart attacks or strokes. Therefore, a clearer understanding of clots form will not only increase our knowledge of blood clot formation in healthy individuals and individuals with cardiovascular diseases, but may potentially lead to a new preventative and therapeutic drugs for heart attack and strokes.

For us to pursue our research on blood clotting, we need fresh blood everyday. This is because the blood cell primarily responsible for blood clotting, platelets cannot survive for more than few house once taken out of our body. In order to study platelet mechanisms regulating blood clotting, we must prepare fresh platelets every single day. Every single morning, we collect donor's blood, isolate platelets and then perform experiments. Without blood for the day we cannot do any research. Thankfully, there are many generous donors who have been helping our research for years; however, the number is never enough. We are always short of blood donors and any additional help from you can make a big difference.

Answer 3

Blood carries Oxygen (O2) to tissues via red blood cells. Red blood cells contain hemaglobin, which carries the oxygen. Blood also carries the by product of cellular respiraton, CO2, out of the tissue and to the lungs for expiration. The blood also does other functions, such as deliver acute and chronic white blood cells and certain hormones.

Answer 4

Probably the most vital reason is that blood is the medium through which oxygen is passed into all the tissues of our body. Without oxygen, the cells die. Another reason is because blood is the path by which the nutrients from food that we need get to the cells that need them.

Answer 5

There are many patients in hospitals that are in dire need of blood donations because they are losing excessive amounts of their own. With blood being a perishable fluid, it is a very delicate and essential function of the body that must be replenished as soon as possible in order to ensure that an individual can survive even after they endure excessive amounts of blood loss. That is why hospitals must always have a fresh supply and why blood donations are so important and always needed.

Answer 6

we need blood to carry oxygen to the rest of the body, its muscles, and organs need the oxygen to function.

Answer 7

to supply oxygen and nutrition for the cells. Also to transport hormones to different parts of the body.

Answer 8

The blood is like a transport system carrying chemicals the body needs to where they are needed and carry waste products away so that the body can get rid of them.
