Understanding Blood Components

This video from Moomoomath discusses the components and functions of blood, which makes up about 7% of body weight. Blood is a connective tissue with roles in oxygen transport, waste removal, temperature regulation, and disease fighting. It consists of red blood cells, white blood cells, plasma, and platelets. Red blood cells carry oxygen and remove carbon dioxide, while white blood cells fight infections. Plasma is mostly water but contains nutrients and waste products. Platelets help in clotting. The video also covers different blood types and concludes with a call to subscribe.
