BIO310H5 Lecture Notes - Homeostasis
Document Summary
Physiology the branch of biology that studies how living things function, especially with respect to the physical and chemical phenomena that are used. Chemical and physical phenomena are limited and bounded by physics and chemistry. All things are connected one way or other. There is a hierarchy of order that determine the physiology which determines the behaviour (or vice versa). Comparative physiology: how different organisms solve similar problems. Understanding the human body in health and disease: humancentric physiological approach. Often uses animal models": animal models are used to figure out how physiological processes work. Types of physiology ii: based on level of study: Cell and molecular physiology mostly in this course. Themes in physiology: physics and chemistry are the basics of physiology. Physiological processes obey the laws of physics and chemistry: physiological systems are regulated: homeostasis and feedback control. Homeostasis: trying to maintain internal body conditions as the external environment changes: temperature, oxygen, glucose, ph, salt.
