The heart is split into two distinct pumps by the Septum.Blood flows into and out of the heart and around the body in one direction.To describe the flow of blood around the heart and the body, you will need to mention that the heart is made up of two pumps.It is the only vein that carries oxygenated blood.Carries oxygenated blood from the lungs to the heart.It is the only artery that carries deoxygenated blood.Carries deoxygenated blood from the heart to the lungs.Carries blood directly into the heart from the body.Carries oxygenated blood directly out of the heart to the body tissues.Ensure the valves stay the right way round and keep the blood flowing in the same direction.Cord like tendons that connect to the tricuspid and bicuspid valves.All valves make sure that the blood flows in one direction, and there is no back flow.Left ventricle pumps blood to the body (systemic circulation).Right Ventricle pumps blood to the lungs (pulmonary circulation).They have thicker walls and are stronger.Left Atrium – receives oxygenated blood from the lungs (Via the pulmonary Vein).Right Atrium – receives deoxygenated blood from the body (Via the Vena Cava).Myocardium (middle layer and most of the heart wall).The Heart sits in a twin layered sac known as the Pericardium.

Structure of the cardiovascular system- heart: Atria Ventricles Bicuspid valve and tricuspid valve Aortic valveand pulmonary valve Aortaand vena cava – superior and inferior Pulmonary vein and pulmonary artery.Then do some light background research on the different labels of the heart including….Task… Find a picture of a blank heart (that is suitable to annotate) and upload it to a blank document. This delivers blood to the working muscles and other tissues.

Main purpose is to drive blood through the arteries.

This can contract continuously without getting tired.

Made up of a special muscle called Myocardium.

Muscular pump, about the size of a clenched fist.
