Explanation:
Heart is the main pumping organ of the body. The human heart is divided into four chambers that are right atria, right ventricles, left atria and left ventricles.
The left and right ventricles can easily be distinguished on the basis of their thickness. The right ventricle is less thicker than left ventricle. The thickness of right ventricle is 9mm whereas the thickness of left ventricle is around 40mm.
Thus, the correct answer is option (B).
Answer: Respiration is a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
Hence, respiration helps to maintain a persons health.
Due to extreme (too much) cell division, a mutation of cells will occur and that is the cancer within humans.
