Blood corpuscles are also known as red blood cells. They are the most common type of blood cell and are responsible for carrying oxygen to the body’s tissues. Blood vessels are the tubes that carry blood throughout the body. They are made up of three layers: the tunica intima, the tunica media, and the tunica adventitia. Proteins in blood are essential for blood clotting and immune function. They also help to transport nutrients and oxygen throughout the body.
In conclusion, Karl Landsteiner discovered blood groups. This discovery was a major breakthrough in medicine, as it allowed for blood transfusions to be performed safely for the first time.
