Composition of Blood
Blood is a complex fluid that is responsible for carrying oxygen and nutrients to all parts of the body and removing waste products. It is composed of water, proteins, red blood cells, white blood cells, and platelets.
Water is the main component of blood, making up about 92% of its total volume.
Proteins are essential for blood's structure and function. They include enzymes, which are responsible for breaking down food molecules, and proteins that help to maintain blood pressure and transport oxygen.
Red blood cells are the most abundant type of blood cell, making up about 45% of its total volume. Red blood cells contain a protein called hemoglobin, which is responsible for carrying oxygen from the lungs to the tissues.
White blood cells are less abundant than red blood cells, making up about 1% of blood volume. White blood cells are responsible for defending the body against infection by attacking bacteria and viruses.
Platelets are the smallest type of blood cell, making up about 1% of blood volume. Platelets are responsible for stopping bleeding by clumping together to form a clot
