Blood Function in Human Body

Blood is a physical fluid in animals that delivers necessary compounds such as nutrients and oxygen to the cells and transportations metabolic waste items far from those very same cells. The components of blood consist of plasma (the liquid part, which contains water, proteins, salts, lipids, and glucose), red cell and leukocyte, and cell pieces called platelets.

Red cell (erythrocyte) deliver oxygen to the cells and remove co2. White blood cells (consisting of neutrophils, monocytes, lymphocytes, eosinophils, and basophils) are involved in the immune response. Platelets form embolisms that avoid blood loss after injury.

Blood Function in Human Body

Blood plays an essential role in controling the body’s systems and maintaining homeostasis. It carries out numerous functions within the body, consisting of:

  • Supplying oxygen to tissues (bound to hemoglobin, which is carried in red cells)
  • Supplying nutrients such as glucose, amino acids, and fatty acids either liquified in the blood or bound to plasma proteins (e.g., blood lipids)
  • Removing waste such as carbon dioxide, urea, and lactic acid
  • Immunological functions, consisting of circulation of leukocyte and detection of foreign product by antibodies
  • Coagulation, which is one part of the body’s self-repair mechanism (blood clotting by the platelets after an open wound in order to stop bleeding)
  • Messenger functions, including the transport of hormonal agents and the signaling of tissue damage
  • Managing body pH
  • Regulating core body temperature
  • Hydraulic functions, consisting of the policy of the colloidal osmotic pressure of blood

Medical terms related to blood often begin with hemo- or hemato- (likewise spelled haemo- and haemato-), which is from the Greek word α (haima) for “blood”. In regards to anatomy and histology, blood is thought about a specialized form of connective tissue, provided its origin in the bones.


  • homeostasis — the ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium
  • coagulation — the process by which blood forms solid clots
  • hydraulic — pertaining to water
