Pertanyaan
The human heart is divided into four chambers ,each of which serves its own function in the cycle of pumping blood.The atria are the thin-walled upper chambers that gather blood as it flows from the veins between heartbeats. The ventricles are the thick-walled lower chambers that Line receive blood from the atria and push it into the arteries with each contraction of the heart. The (5)left atrium and ventricle work separately from those on the right. The role of the chambers on the right side of the heart is to receive oxygen-depleted blood from the body tissues and send it on to the lungs;the chambers on the left side of the heart then receive the oxygen-enriched blood from the lungs and send it back out to the body tissues. 5. The passage indicates that the ventricles (A) have relatively thin walls (B) send blood to the atria (C) are above the atria (D) force blood into the arteries 6. According to the passage, when is blood pushed into the arteries from the ventricles? (A) As the heart beats (B) Between heartbeats (C) Before each contraction of the heart (D) Before it is received by the atria 7. Which one of the following drawings that highlights the part of the heart that gets blood from the body tissues and passes it on to the lungs?
