Document Summary

Physiology = study of all the processes in a living organism = knowledge of nature. Systems connected, and changes to one system will likely affect others. Circulatory heart, blood vessels, blood transport of materials. Digestive stomach, intestines, liver, pancreas food -> particles.

Nervous brain, spinal cords, nerves coordination of body functions via electrical signals and release of regulatory molecules. Reproduction ovaries, uterus, testes species reproduction. Respiratory lungs, airways affects all other systems exchange of oxygen and co2. Urinary kidneys, bladder maintenance of fluid and solute molecules.

Negative feedback - response slows down stimulus (hormones) Feedback loops are not biological rhythms (eg. circadian rhythms).
