BLOCK 2: Cardiac Physiology (Part 2)
You must first login to purchase this item.
Welcome to our block on Cardiac Physiology (Part 2)! The heart, with its rhythmic pulsations, not only signifies life but also the intricate dance of processes, mechanisms, and reactions that ensure our body's systematic function. This block will delve deep into understanding these complexities, providing both foundational knowledge and advanced insights.

Why is this block important?
The heart and the circulatory system are central to our body's function, ensuring every cell gets the oxygen and nutrients it requires. To safeguard health and treat cardiovascular ailments, a profound understanding of cardiac processes, their regulation, and the pharmacological interventions available is essential.
