About Blood
Understanding Blood
Blood is a vital fluid that circulates through our bodies, delivering essential substances such as nutrients and oxygen to the cells and transporting metabolic waste products away from those same cells. It consists of plasma, red blood cells, white blood cells, and platelets.
Blood plays a crucial role in maintaining our health and is essential for life. Understanding blood types, compatibility, and the donation process is important for both donors and recipients.
