Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In what order does blood flow through the body and heart?
A
Rt atrium, Lt atrium, lungs, Rt vent, Lt vent, body.
B
Rt atrium, Lt vent., lungs, Lt atrium, Rt vent., body.
C
Rt atrium, Rt vent., lungs, Lt vent., Lt atrium, body.
D
Rt atrium, Rt vent., lungs, Lt atrium, Lt vent., body.
Explanation: 

Detailed explanation-1: -Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.

Detailed explanation-2: -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-3: -The left atrium receives blood that’s been oxygenated by lungs and blood enters the left atrium from the four pulmonary veins. The left atrium contracts and blood flows through the mitral valve into the left ventricle. The left ventricle contracts and blood is pumped through the aortic valve into the aorta.

Detailed explanation-4: -So, the correct answer is ‘Right ventricle, pulmonary arteries, lungs, pulmonary veins, 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
