Supplement

A biological system, sometimes simply referred to as system, is a group of entities or organs that work together to carry out a particular task. It is a biological unit of the body or of an organism. In higher forms of organisms such as vertebrates (including humans), the biological systems include integumentary system, lymphatic system, muscular system, nervous system, reproductive system , respiratory system, skeletal system, endocrine system, immune system, and urinary system. One particular example is the cardiovascular system. The cardiovascular system is an organ system in which the blood is pumped through the heart and circulates throughout the body through the blood vessels. In humans and other mammals, its components include heart, blood vessels, and blood. Another example of a biological system is the nervous system. A human central nervous system is comprised of the brain, the spinal cord, and the peripheral nervous system. Its main function is for coordinating actions by transmitting signals to and from different parts of the body.

In a micro-level (such as in bacteria and microscopic eukaryotes), a biological system pertains to the macromolecular complexes or organelles within the cell.
