metabolic equilibrium actively maintained by several complex biological mechanisms that operate via the autonomic nervous system to offset disrupting changes.
components: organs of gastrointestinal tract, a long tube that includes the mouth, pharynx (throat), esophagus, stomach, small and large intestines, and anus; also includes accessory organs that assist in digestive processes, such as salivary glands, liver, gallbladder, and pancreas; functions: achieves physical and chemical breakdown of food; absorbs nutrients; eliminates solid wastes.
the body's speedy, electrochemical communication system, consisting of all the nerve cells of the peripheral and central nervous systems.
the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream.
Eliminates waste products from the body in ways that maintain homeostasis.
a system (including the thymus and bone marrow and lymphoid tissues) that protects the body from foreign substances and pathogenic organisms by producing the immune response.
brings air into the body and removes carbon dioxide. It includes the nose, trachea, and lungs.
System of organs and blood that brings nutrients and oxygen to cells and carries away wastes. In higher vertebrates, the system has a pulmonary and systemic circuit. The pulmonary circuit carries blood to the lungs to be oxygenated, while the systemic circuit carries oxygenated blood to the body. Vertebrates have a closed circulatory system, while arthropods have an open system.
