Cardiovascular system

The cardiovascular system delivers oxygen, nutrients, and hormones to tissues while removing carbon dioxide and metabolic waste. It consists of the heart, blood vessels, and blood itself, working in constant rhythm to sustain life. Functions include circulation, blood pressure regulation, and temperature control. Understanding its anatomy and physiology reveals how disruptions, such as hypertension, heart failure, or vascular disease, can impair overall health. Research continues to illuminate how lifestyle, genetics, and environment affect cardiovascular functioning.
