there are 4 components of blood: Red Blood Cells (RBC, White Blood Cells (WBC), Plasma, and Platelets.
What are the components of blood?
Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. The main function of these WBC cells is to protect the body from getting affected by foreign particles. Whenever an infection or foreign particle invades the body, the WBC builds up the antibodies and attacks the germs to destroy it. The function of plasma is to transport cells throughout the body, along with nutrients. Your platelets function to stop bleeding. During an injury, your platelets will cluster together at the site of the wound to act as a plug.
What are the functions of all of them?
