Blood Vessels

Your blood is a crucial part of your body, it is important for functioning. It carries oxygen and fights the diseases and germs. Your blood contains four main cells white blood cells, red blood cells, plasma, and platelets. Your blood is about 54% plasma, 45% red blood cells, and approximately 1% white blood cells and platelets. They all have their own functions and uses. The white blood cells are the cells that fight germs and diseases, they are like the first responders on the scene of a car crash, there are other things that fight diseases as well. Platelets on the other hand ar the things that stop you from bleeding to death by forming blood clots. Plasma is what transports things like CO2, nutrients, and hormones to your cells. Red blood cells are what carry oxygen around your body, they contain haemoglobin which grabs the oxygen. Those are all the main blood cells in your body. They're separated when your donating blood since they only need the red blood cells.
