Answer: The question is incomplete,below is the complete question.
The following is a list of vessels and structures that are associated with the heart. 1. right atrium 2. left atrium 3. right ventricle 4. left ventricle 5. vena cavae 6. aorta 7. pulmonary trunk 8. pulmonary veins
What is the correct order for the flow of blood entering from the systemic circulation?
A) 5, 1, 3, 7, 8, 2, 4, 6
B) 1, 2, 7, 8, 3, 4, 6, 5
C) 5, 3, 1, 7, 8, 4, 2, 6
D) 5, 1, 3, 8, 7, 2, 4, 6
E) 1, 7, 3, 8, 2, 4, 6, 5
The correct answer to the question is option A
5, 1, 3, 7, 8, 2, 4, 6
Vena cavae---Right atrium---Right ventricle---Pulmonary trunk---pulmonary veins---Left atrium---Left ventricle---Aorta.
Explanation: Deoxygenated blood enters the right atrium of the heart through the inferior and superior vena cavae,the right atrium contracts opening the tricuspid valve and the blood in the right atrium empties into the right ventricle and the valve closes to prevent the backflow of blood.the right ventricle further contrasts and the pulmonary valve opens,the content of the right ventricle flows into the pulmonary trunk and goes into the left and right pulmonary arteries,the pulmonary arteries empties it's blood content into the left and right lungs where there will be exchange of gases,carbon dioxide will be released and oxygen will be taken in,the oxygenated blood from the lungs flows into the left atrium via the pulmonary veins,the left atrium contracts and the mitral valve open giving way for the content of the left atrium to empty into the left ventricle then the valve closes to prevent backflow of blood,the left ventricle further contracts,the aortic valve opens and the content of the left ventricle emptied into the aorta, to the aortic trunk and further into the arc of aorta from where it goes into systemic circulation via the brachiocephalic artery,left common carotid artery and the left subclavian artery.
Option A is correct. The correct order of blood flow is Vena cava, Right atrium, Right ventricle, Pulmonary trunk, pulmonary veins, Left atrium, Left ventricle, and Aorta.
Blood flow in heat:
The deoxygenated blood is pumped into lungs while oxygenated blood is pumped to the whole body by heart.
- Deoxygenated blood from body come to the right atrium via vena cava.
- From right atrium blood, empties into left ventricle.
- Left ventricle send this blood to lungs via pulmonary artery.
- Blood gets oxygen in the lungs and become oxygenated.
- The oxygenated blood comes to the left atrium
- From left atrium blood empties into the left ventricle.
- Left ventricle send this blood to the whole body via aorta.
Therefore, the correct order of blood flow is Vena cavae, Right atrium, Right ventricle, Pulmonary trunk, pulmonary veins, Left atrium, Left ventricle, and Aorta.
