Understanding Blood Components

This video from Moomoomath discusses the components and functions of blood. Blood is crucial for life, making up about 7% of body weight and performing 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, plasma, and platelets. Red blood cells transport oxygen and remove carbon dioxide, while white blood cells are key to the immune system. Plasma, mostly water, carries essential substances, and platelets help in clotting. The video concludes with a reminder of blood's essential role in life.
