Blood
Blood is a vital fluid in the human body that functions much like a transportation system. It carries essential substances such as oxygen, nutrients, and hormones to cells throughout the body. Blood is also responsible for removing waste products like carbon dioxide and urea, maintaining homeostasis and supporting overall cellular health.
Blood comprises four primary components: red blood cells, white blood cells, platelets, and plasma. Red blood cells are tasked with transporting oxygen, while white blood cells are crucial for the immune system, fighting off infections. Platelets help with blood clotting to stop bleeding, and plasma, the liquid part, carries nutrients, waste, and other cells.
The continuous circulation of blood through the heart, arteries, veins, and capillaries ensures that the body's needs are constantly met. It also plays a part in regulating body temperature and pH balance. Blood is an essential element of the human body's defense and regulatory systems, sustaining life and facilitating recovery from injury or illness.
