L1 Intro
Physiology and anatomy
Dr Greg Knock
Be able to define anatomy and physiology:
Anatomy: study of structure of living organisms.
Histology: structure of cells and tissues
Topographical anatomy: structure of organisms and their relation to each other in the body.
Physiology: study of how living organisms function. Describing functions of bodily systems and their
organs and tissues. Understanding how that function is controlled and maintained and to what
purpose. Abnormal function: patho- physiological.
Histology relates to function. E.g. the nephrons- produce urine.
Topography relates to function. E.g. the lungs- enable flow of air in and out of lungs for gaseous
exchange.
Homeostasis: the dynamic maintenance of physiological variables within a predictable range.
All molecules, cells, tissues and organs obey the laws of physics. Pressure, flow and resistance,
diffusion, gas laws, and Laplace’s law.
