APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body.

Detailed explanation-2: -It’s the muscle at the centre of your circulation system. It pumps blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.

Detailed explanation-3: -Cardiac: These muscles line the heart walls. They help your heart pump blood that travels through your cardiovascular system. You don’t control cardiac muscles.

Detailed explanation-4: -The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

Detailed explanation-5: -Rapid, involuntary contraction and relaxation of the cardiac muscle are vital for pumping blood throughout the cardiovascular system.
