Detailed explanation-1: -Your heart and many blood vessels in your body make up your cardiovascular system or circulatory system. Your heart uses the far-reaching, intricate network of blood vessels to deliver oxygen and other necessary things to your whole body.

Detailed explanation-2: -Your heart is the only circulatory system organ. Blood goes from the heart to the lungs to get oxygen. The lungs are part of the respiratory system. Your heart then pumps oxygenated blood through arteries to the rest of the body.

Detailed explanation-3: -The heart is the key organ of the cardiovascular system – the body’s transport system for blood. A muscle that contracts rhythmically and autonomously, it works in conjunction with an extensive network of blood vessels running throughout the body.

Detailed explanation-4: -Your heart is the main organ of your cardiovascular system, a network of blood vessels that pumps blood throughout your body. It also works with other body systems to control your heart rate and blood pressure. Your family history, personal health history and lifestyle all affect how well your heart works.

Detailed explanation-5: -The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle).
