Cardiovascular System + Fluids
from MCAT Basics (from MedSchoolCoach) Hosted by Health Admissions IQ
In this episode, we focus on the cardiovascular system and its connection to fluid mechanics. Beginning with an exploration of cardiovascular anatomy, the discussion covers various aspects of the heart: its function, contraction mechanism, the diverse cell types found within it, and its essential role in regulating blood pressure. Finally, in the latter part of the episode, several fluid mechanics topics pertinent to the MCAT and their application to the cardiovascular system are addressed. These include total peripheral resistance, viscosity, the continuity equation, and the Bernoulli equation, offering insights into their relevance in understanding cardiovascular dynamics.
