Biology Exam - Some Basic Knowledge And Facts About Blood

Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. In vertebrates, it is composed of blood cells suspended in blood plasma. Biology Exam - Some basic knowledge and facts about Blood
