Blood

Blood is a vital fluid that circulates throughout the body, delivering oxygen, nutrients, hormones, and immune cells to various organs and tissues while removing waste products and carbon dioxide. It consists of plasma, red blood cells, white blood cells, and platelets. Red blood cells contain hemoglobin, which binds and transports oxygen, while white blood cells are essential for the immune system, defending the body against infections. Platelets play a crucial role in blood clotting, preventing excessive bleeding. Regular blood tests are an essential tool for diagnosing and monitoring various health conditions, including anemia, infections, and disorders affecting blood cell counts and clotting factors.
