Blood is a vital fluid in the human body that is responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body. It is composed of several different components, including red blood cells, white blood cells, platelets, and plasma.
Red blood cells are responsible for carrying oxygen from the lungs to the rest of the body and removing carbon dioxide. White blood cells are part of the immune system and help to fight off infections and diseases. Platelets are essential for blood clotting and preventing excessive bleeding. Plasma is the liquid component of blood that carries all the other components and also contains proteins, electrolytes, hormones, and waste products.
Blood is produced in the bone marrow and is constantly circulating throughout the body in a network of blood vessels. It plays a crucial role in maintaining homeostasis and keeping the body functioning properly. Blood tests can provide valuable information about a person's overall health, including their red and white blood cell counts, cholesterol levels, and presence of any infections or diseases.

Blood is a vital fluid that flows throughout the body, delivering oxygen, nutrients, hormones, and other essential substances to cells and tissues while removing waste products.
Composition:
- Plasma (55%): Liquid component that contains water, dissolved salts, hormones, proteins (including clotting factors and antibodies), and nutrients.
- Red blood cells (45%): Contain hemoglobin, a protein that binds to oxygen and transports it throughout the body.
- White blood cells (less than 1%): Protect the body from infection and disease.
- Platelets (less than 1%): Aid in blood clotting.
Functions:
- Oxygen transport: Red blood cells carry oxygen from the lungs to cells throughout the body.
- Nutrient delivery: Plasma carries glucose, amino acids, vitamins, and other nutrients to cells.
- Waste removal: Plasma transports waste products, such as carbon dioxide and urea, to the kidneys and liver for excretion.
- Hormone transport: Plasma transports hormones from endocrine glands to target organs.
- Regulation of body temperature: Blood acts as a heat transfer fluid, distributing heat throughout the body.
- Protection from infection: White blood cells attack and destroy microorganisms.
- Blood clotting: Platelets and clotting factors help stop bleeding by forming a clot that plugs damaged blood vessels.
Types of Blood Groups:
Blood is classified into different groups based on the presence or absence of two antigens, A and B, on the surface of red blood cells:
- Type A: Has A antigens only
- Type B: Has B antigens only
- Type AB: Has both A and B antigens
- Type O: Has neither A nor B antigens
Blood Transfusions:
Blood transfusions involve transferring blood from a donor to a recipient. They are often necessary in cases of blood loss, anemia, or other medical conditions. Compatibility between donor and recipient blood groups is essential to prevent transfusion reactions.
Other Functions:
- Acid-base balance: Blood buffers help maintain the body's pH within a narrow range.
- Fluid balance: Blood helps regulate body fluid volume and pressure.
- Electrolyte balance: Blood contains electrolytes (e.g., sodium, potassium) that are essential for proper cell function.
