MEDICAL PHYSIOLOGY

Detailed explanation-1: -The left ventricle has the thickest wall out of all the chambers. The left ventricle is responsible for pumping the blood towards the tissues of the heart. This is why more muscles contracting inside the left ventricle helps produce a higher force to move the blood towards the system.

Detailed explanation-2: -The myocardium is thickest in the left ventricle, as the left ventricle must create a lot of pressure to pump blood into the aorta and throughout systemic circulation. Cardiac muscle has a high density of mitochondria and a large blood supply, which keep it functioning continuously.

Detailed explanation-3: -The muscles of the heart, termed the myocardium, make up the middle and thickest layer of the heart wall.

Detailed explanation-4: -Left ventricle which has to pump blood into the largest network of blood vessels and has to pumps blood against greater resistance than any other chambers of the heart. Hence, the left ventricle has the thickest muscular wall.

Detailed explanation-5: -The myocardium is functionally the main constituent of the heart and the thickest layer of all three heart layers. It is a muscle layer that enables heart contractions.
