The cardiovascular system, also known as the circulatory system, plays a fundamental role in maintaining homeostasis by transporting oxygen, nutrients, hormones, and waste products throughout the body. The heart serves as the central organ of this system, acting as a pump that ensures continuous blood circulation. This paper provides an overview of the structure and function of the heart and cardiovascular system, discusses the physiological mechanisms that sustain circulation, and highlights the common disorders affecting cardiovascular health. Findings indicate that maintaining cardiovascular efficiency depends on lifestyle factors such as diet, exercise, and stress management. The study underscores the importance of cardiovascular education for disease prevention and overall well-being.
