Blood is a complex living tissue that includes plasma, red blood cells, white blood cells, and platelets. It performs vital functions such as transporting oxygen and nutrients, helping the body defend itself, and clotting to stop bleeding. Blood is composed of approximately 55% plasma, which contains water, proteins, and salts. Red blood cells are responsible for carrying oxygen thanks to hemoglobin, while white blood cells play a role in immunity. Platelets assist in wound healing. The volume of blood in an adult is about 5 liters, pumped by the heart at a rate of 5 to 6 liters per minute, depending on the cardiovascular system. Blood deficiency, such as anemia caused by iron or vitamin deficiencies, reduces the blood's ability to deliver oxygen, leading to symptoms like fatigue and shortness of breath. Diagnosis requires blood tests and identifying the underlying cause. Methods to maintain healthy blood include a healthy lifestyle, consuming a balanced diet rich in iron, vitamin B12, and folate, paying attention to hydration needs, and avoiding smoking. Treating anemia involves addressing its underlying causes rather than just taking supplements.
