Understanding Blood Components

This video from Mumu Math and Science explains the components and functions of blood. Blood makes up about 7% of body weight and performs vital roles such as transporting oxygen, removing waste, regulating temperature, fighting disease, and carrying nutrients. Blood can be separated into red blood cells, white blood cells, and plasma. Red blood cells transport oxygen and remove carbon dioxide, while white blood cells are crucial for the immune system. Plasma, mostly water, contains essential substances, and platelets help in clotting. The video concludes with a reminder of blood's essential role in life.
