Detailed explanation-1: -Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.

Detailed explanation-2: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Detailed explanation-3: -Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

Detailed explanation-4: -When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen. It then leaves the lungs to return to the heart through the pulmonary vein. The blood enters the left atrium.

Detailed explanation-5: -Deoxygenated blood starts to run from the body. It flows into Superior/ Inferior Vena Cava. The flow of deoxygenated blood reaches the right atrium. The atrium will push the flow through the Tricuspid valve. The gore stays in the right ventricle. More items •30-Mar-2022
