Abstract:
The human body is composed of approximately 60% fluids, many of which undergo oscillatory motion. From the rhythmic pumping of blood by the heart through the vessels to the cyclical flows of respiration in our lungs and the peristaltic movements in our gut, these oscillations play a crucial role in maintaining bodily functions. They facilitate the delivery of nutrients to tissues, such as oxygen transported by the blood; aid in the removal of waste products through, for example, the lymphatic system; and help regulate physiological processes, such as the exchange of gases in the lungs through respiratory oscillations. In this talk, I will focus on two particular flows. The first is the dynamics of aqueous humor, a Newtonian fluid found in the anterior chamber of the eye (the region between the cornea and the iris) during eye rotations. This flow is responsible for delivering nutrients to the avascular tissues of the cornea and the lens. The second part of my talk will examine the oscillatory flow of cerebrospinal fluid around the brain during the cardiac cycle and its importance in clearing metabolic waste and delivering drugs.
