This course deals with the principles of fluid statics and their applications in both physical and biological systems. It begins with the study of cohesion and adhesion in liquids, leading to an understanding of surface tension, pressure differences inside droplets and bubbles, and the phenomenon of capillary actionThe course then connects these fundamental concepts to the human body, exploring how fluid pressure operates in physiological systems. Topics include blood pressure and circulation, intraocular (eye) pressure, pressures associated with the lungs and breathing mechanics, and other important internal pressures such as those in the spinal column and skull, bladder pressure, and pressures within the skeletal system.
