This course offers an introductory yet in-depth exploration of the cardiovascular system, covering the heart, blood vessels, and circulation. Learners will understand how blood flow supports oxygen delivery and immune function while examining key concepts such as the cardiac cycle, blood pressure, and blood composition.

The heart, a tireless and highly active organ, demands a continuous and adequate blood supply to sustain its vital function. Although the heart chambers contain blood, this blood does not directly nourish the heart muscle (myocardium). Instead, the heart relies on a dedicated network of coronary arteries to deliver oxygen and essential nutrients, …
