The primary function of the heart is to serve as a muscular pump propelling blood into and through vessels to and from all parts of the body. The almost continuous traffic into and out of a busy factory at rush hour occurs at a snails pace compared to the endless activity going on within our bodies.
Nervous And Vascular System
Responsible for transporting oxygen nutrients hormones and cellular waste products throughout the body the cardiovascular system is powered by the bodys hardest working organ the heart which is only about the size of a closed fist.
Anatomy of the vascular system. Cardiovascular system anatomy and physiology. The cardiovascular system is made up of the blood heart and blood vessels. The cardiovascular system consists of the heart which is an anatomical pump with its intricate conduits arteries veins and capillaries that traverse the whole human body carrying blood.
The cardiovascular system consists of the heart blood vessels and the approximately 5 liters of blood that the blood vessels transport. Arteries carry oxygen rich blood away from your heart and veins carry oxygen poor blood back to your heart. Anatomy of the vascular system the vascular system is a network of arteries veins and capillaries that supplies blood to the tissues of the body.
Like the bustling factory the body must have a transportation system to carry its various cargos back and forth and this is where the cardiovascular system steps in. It is the pulmonary artery that brings oxygen poor blood into your lungs and the pulmonary vein that brings oxygen rich blood back to your heart. In pulmonary circulation though the roles are switched.
The blood contains oxygen nutrients wastes and immune and other functional cells that help provide for homeostasis and basic functions of human cells and organs. The muscles that are contracting require a continual supply of nutrients and oxygen to support energy production. The main responsibility of the cardiovascular system is transportation of blood to all parts of the body.
