Step-by-step explanation:
Note that the nature of the blood can be oxygenated blood and non-oxygenated blood. Throughout the explanation and the answer, the nature of the blood in the blood flow in the cardiovascular system will be commented on.
To analyze the flow of blood in the cardiovascular system, we have the following particularities within the heart:
On the right side of the heart, poorly oxygenated blood from all the body's organs enters the right atrium through the superior vena cava and the inferior vena cava.
The tricuspid valve opens to let blood travel from the right atrium to the right ventricle.
When the right ventricle is full of blood, the right ventricle contracts, causing the tricuspid valve to close and the pulmonary valve to open.
The blood then flows through the pulmonary artery to the lungs, where gas exchange begins in the alveoli where the blood releases carbon dioxide and absorbs oxygen.
Now, blood flow continues to the left side of the heart.
On the left side of the heart oxygen-rich blood travels from the lungs to the left atrium through large veins called pulmonary veins.
At this time, the mitral valve opens so that blood passes from the left atrium to the left ventricle.
Now, when the left ventricle is full of blood, this ventricle contracts, which closes the mitral valve and opens the aortic valve.
Finally, your heart sends oxygen-rich blood through the aortic valve to the aorta, where it flows to the rest of the body.
We can conclude that the correct answer is:
