The circulatory system, composed of the center, blood, and blood vessels, circulates a transportation fluid through the body, giving the cells with a steady provide of oxygen and nutrients and carrying absent waste merchandise for instance carbon dioxide and harmful nitrogen compounds.

Cardiovascular process Transportation of oxygen, nutrients and hormones all through the body and elimination of mobile metabolic squander Respiratory system Trade of oxygen and carbon-dioxide involving the body and air, acid-base balance regulation, phonation. Nervous system Initiation and regulation of critical body features, feeling and body movements. Digestive method Mechanical and chemical degradation of food items with objective of absorbing into your body and making use of as Electricity. Urinary system Filtration of blood and eliminating unneeded compounds and squander by generating and excreting urine. Endocrine process Manufacture of hormones in an effort to control numerous types of bodily capabilities (e.

Primary immune response The immune method contains the white blood cells, the thymus, lymph nodes and lymph channels, that happen to be also part of the lymphatic system.
