Facts about Blood

Blood is a vital fluid in the human body, responsible for transporting oxygen and nutrients to cells while removing waste products. It consists of red blood cells, white blood cells, platelets, and plasma, each playing a crucial role in maintaining overall health. The average adult has about five to six liters of blood, which accounts for approximately 7-8% of their total body weight. Blood also plays a key role in regulating body temperature and pH levels, as well as in the immune response, helping to protect the body against infections and diseases. Understanding the composition and functions of blood is essential for recognizing its importance in medical science and health.
