Question

Read the text and fill in the following words: Atrium,blood, capillaries,circuit (2), fluid, heart, lungs, pump, side, systemic, tissues, ventricle,vessels. 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.

Answer 1

Read the text and fill in the following words:

Atrium, blood, capillaries, circuit (2), fluid, heart, lungs, pump, side, systemic, tissues, ventricle, vessels.

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.

Answer 2

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 atria. 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 back 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 of half a millimeter 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.
