Answer:
Blood enter the right atrium of the heart via the vena cava (superior and inferior)
The right atrium contracts to push the blood into the right ventricle through the triscupid valve
The contraction of the right ventricle pushes the blood through the pulmonary valve to the pulmonary artery which carries it to the lungs to be oxygenated
After oxygenation, the pulmonary vein brings blood to the left atrium
Contraction of the left atrium pushes the blood through the mitral valve into the left ventricle
The left ventricle contracts to push the blood through the aortic valve, into the aorta, which carries the blood through the body.

Answer: Mitosis
Explanation:
Since meiosis helps only in the production of gametes, mitosis helps the somatic cells in the already fertilized egg (zygote) to do the following:
- multiply their number, thus aiding growth
- form new cells like red blood cells to transport oxygen, white blood cells to fight infection, liver cells etc
Thus, for growth mitosis is the mechanism used to generate more cells
<span>New kingdoms were needed that reflected our growing knowledge of the differences between living organisms.
The classification system requires criteria to differ the organism. As the technology and research advance, we can observe more characteristic of many organisms and found more differences between them.</span>
