This episode covers heart anatomy, blood flow through the pulmonary and systemic circuits, the cardiac cycle (systole/diastole), the heart's electrical conduction system, and how to interpret an ECG. Companion notes and flashcards at: https://reviewmcat.com/cardiovascular_1_heart

This episode provides a comprehensive review of the endocrine system, covering hormone types, signaling pathways, and feedback regulation. We tour the major endocrine glands and their hormones, and explain key regulatory axes like the HPA, HPG, HPT, and RAAS, along with relevant disorders.

In this episode of the MCAT Prep Pod Biology Series, we break down the full process of cell division, including the cell cycle, mitosis, and meiosis. You’ll learn the key stages (G1, S, G2, PMAT), checkpoint regulation, and how mitosis creates identical cells while meiosis generates genetic diversity through crossing [...]

In this episode of the MCAT Prep Pod Biology Series, we wrap up core cell biology by diving into high-yield MCAT topics like prokaryotic cells, bacterial classification, and viral replication strategies. We explore the structure and function of bacteria and archaea, including cell wall differences (Gram-positive vs. Gram-negative), oxygen requirements [...]

This episode covers the foundations of cell theory, the differences between prokaryotic and eukaryotic cells, and the structure and function of organelles like the nucleus, mitochondria, lysosomes, ER, and Golgi apparatus. You’ll learn about the plasma membrane, including the fluid mosaic model, passive and active transport, osmosis, and bulk transport. [...]
