Everything you wanted to know about blood
(but were too afraid to ask)
What’s it even for?
Like a lot of things in the human body, blood is a fantastic multi-tasker. It’s responsible for supplying nutrients, sugars, oxygen and hormones around a body, it removes waste such as carbon dioxide and lactic acid from cells throughout the body, it helps with regulating temperature and acidity, and it fights infections. So you could say it’s important.
Part of the reason blood does so many things is that it’s made up of different components. These components – red blood cells, white blood cells, plasma, and platelets – each handle a different task.
Why do we need to study it?
While blood has a number of functions, it can also be affected by a number of dangerous diseases. For example, leukaemia is a type of cancer that can lead to high production of abnormal white blood cells, at the expense of red blood cells and platelets. Haemophilia, on the other hand, is a condition in which blood does not clot properly, leading to potentially severe bleeding from the most minor cuts.
Each of these blood diseases requires a different treatment – whether by giving regular transfusions of the right blood type, or making clotting factor concentrates from donated blood.
