The cardiovascular system is a cornerstone of human physiology and a major focus in pharmacology. For B.Pharm students, a solid understanding of the heart’s anatomy, the cardiac cycle, blood circulation, and the regulation of blood pressure is essential. This system is the target of many critical drug classes, and this quiz will test your foundational knowledge of its structure and function, which is vital for comprehending cardiovascular medicine.
