The human cardiovascular system consists of the heart, the blood vessels, and blood.
The ---------- is a muscular organ lying slightly to the left of the middle of the chest between two ------.
The heart acts as a -------, which pumps blood round two independent circuits: the pulmonary---------- and the systemic -----------. The right side of the heart , consisting of the right atrium and the right ventricle sends ------- into the lungs. The left side consisting of the left -------- and left --------- and sending blood throughout the whole body, pumps with more force than the right ventricle.
The ---------circuit is much larger , so the left -------of the heart is stronger and thicker than the right.
There are three kinds of blood ------------: arteries, veins,and capillaries. Arteries are vessels carrying blood away from the herat.Veins are vessels carrying blood from the ------ --- to the heart. The blood vessels are supplied with nerves . ------------ are tiny vessels which connect the smallest arteries and veins. In the capillaries the blood is moving along at the rate half a millimetre per second.
Blood is the ------------circulating through the heart , arteries, capillaries,and veins. The order of blood flow is:
HEART- ARTERIES –CAPILLARIES – VEINS – HEART.

The human cardiovascular system consists of the heart, the blood vessels, and blood.
The --heart--- is a muscular organ lying slightly to the left of the middle of the chest between two ---lungs---.
The heart acts as a ---pump--, which pumps blood round two independent circuits: the pulmonary---circuit--- and the systemic ---circuit---. The right side of the heart, consisting of the right atrium and the right ventricle sends ----blood--- into the lungs. The left side consisting of the left ---atrium--- and left ---ventricle--- and sending blood throughout the whole body, pumps with more force than the right ventricle.
The ---systemic--- circuit is much larger , so the left ---side---- of the heart is stronger and thicker than the right.
There are three kinds of blood ---vessels: arteries, veins, and capillaries. Arteries are vessels carrying blood away from the heart. Veins are vessels carrying blood from the --tissues-- to the heart. The blood vessels are supplied with nerves . --Capillaries--- are tiny vessels which connect the smallest arteries and veins. In the capillaries the blood is moving along at the rate half a millimetre per second.
Blood is the --fluid--- circulating through the heart , arteries, capillaries,and veins. The order of blood flow is: HEART- ARTERIES –CAPILLARIES – VEINS – HEART.
