The entire cardiac cycle is as follows:
- Deoxygenated blood enters the right ventricle from the superior and inferior vena cava.
- The right atrium pumps the deoxygenated blood to the right ventricle.
- From the right ventricle, the deoxygenated blood moves to the lungs via the pulmonary artery.
- After gaseous exchange, the oxygenated blood returns to the heart into the left atrium via the pulmonary vein.
- From the left atrium, blood moves to the left ventricle.
- Oxygenated blood is pumped by the left ventricle into the aorta which supplies blood to all parts of the body.
- Deoxygenated blood, collected from the body again enters into the right atrium via the vana cava.
The correct answer would be D, because the ending result for mitosis is 2 diploid cells, meaning the number chromosomes are the same. While in meiosis, the ending result is 4 haploid cells. Because the cell was divided twice, this means that each daughter cell has half of the number of chromosomes.
