MICROANATOMY

Detailed explanation-1: -A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.

Detailed explanation-2: -Overview. The heart muscle is responsible for circulating blood throughout the body. The heart has four chambers, two upper (atrium) and two lower (ventricle), with one atrium and one ventricle on both the right and left side of the heart.

Detailed explanation-3: -The ventricles are the two lower chambers of the heart, one on the right and one on the left. The ventricles receive blood from the heart’s upper chambers (atria) and pump it to the rest of the body. The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to the rest of the body.

Detailed explanation-4: -The heart has four chambers. The upper two chambers are the atria, and the lower two are the ventricles (Figure A). The chambers are separated by a wall of tissue called the septum.

Detailed explanation-5: -ventricles (VEN-trih-kuhls): The two chambers at the bottom of the heart are called the ventricles. The heart has a left ventricle and a right ventricle. Their job is to pump the blood to the body and lungs.
