Answer:
Explanation:
The width of the muscular wall (myocardium) in the ventricles is greater than the width of the atria due to the force exerted by the heart to initiate major circulation (left ventricle) and minor or pulmonary circulation (right ventricle).
This is because in the human circulatory system, the major / systematic circulation that sends oxygen-rich blood (O2) and nutrients to the organs, starts from the left ventricle and ends in the right atrium, where blood is collected with the debris from cellular respiration. Then it passes through the tricuspid valve to the right ventricle and the minor / pulmonary circulation begins at the moment that the ventricle contracts strongly and expels the blood into the lungs, where the gas exchange in the pulmonary alveoli will occur again oxygenating the blood and being collected by the left atrium that connects to the left ventricle through the bicuspid or mitral valve and the process of major circulation begins again.
Because it’s in smaller price so therefore can’t melt faster than the block, since the smaller peices will melt at the same time as one another.
The right answer is supplying oxygenated blood to the arteries that travel to all major body parts
Aorta is the principal artery of the body.
It starts from the left ventricle of the heart, passes through the thorax and abdomen to separate at the lower part of the abdomen, into two branches called common iliac arteries for the lower limbs. We talk about thoracic aorta then abdominal aorta along its path in relation to the anatomical position. All arteries in the body (carrying oxygenated blood) are directly or indirectly derived from the aorta except the pulmonary artery.
The answer is 18. Good luck.
