MCAT Basics (from MedSchoolCoach)

Cardiovascular System + Fluids

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.

Translational Motion

This podcast addresses translational motion. First, vectors are covered. Then, the variables of acceleration, velocity, and position are discussed. Next, the host discusses the relationship between those three variables. Finally, it covers free fall, projectile motion, air resistance, and friction.

Cell Organelles

This podcast explores cell organelles, organized into five categories: organelles found in all cells, eukaryotic cells, plant and bacterial cells, human and bacterial cells, human cells only, and plant cells only. The organelles discussed include ribosomes, vacuoles, cytoskeleton, plasma membrane, peroxisome, proteasome, nucleus, nucleolus, smooth and rough endoplasmic reticulum, Golgi apparatus, lysosome, cell wall, flagella, mitochondria, melanosome, and chloroplasts.

Kinetics and Solubility

This podcast discusses chemical kinetics and solubility. It begins with an exploration of kinetics, including the general concept, collision theory, rate laws, and the Arrhenius equation. Next, it delves into solubility, covering the general concept, solubility product (Ksp), the common ion effect, selective precipitation, and Henry’s law.
