What is the general anatomy of the heart?

The heart is made up of four chambers: two upper chambers known as the left atrium and right atrium and two lower chambers called the left and right ventricles. It is also made up of four valves: the tricuspid, pulmonary, mitral and aortic valves.

What is the functional anatomy of the heart?

The heart contains four inner chambers: two atria (upper chambers) and two ventricles (lower ventricles). The pulmonary trunk is a vessel that brings deoxygenated blood from the left ventricle into the lungs. Pulmonary veins return the oxygenated blood from the lungs back into the heart.

What is heart anatomy and physiology?

The heart has a middle muscular layer, the myocardium, made up of cardiac muscle cells, and an inner lining called the endocardium. The inside of the heart (heart cavity) is divided into four chambers – two atria and two ventricles – separated by cardiac valves that regulate the passage of blood.

What is the apex of the heart anatomy?

In the anatomical position, the apex of the heart is the confluence of the inferior and left borders. It is a projection inferiorly, anteriorly and to the left of the left ventricle. Anterolaterally, it is covered by the anterior surface of the mediastinal pleura.

What is the main function of the heart?

Your heart is the primary organ of your circulatory system. It pumps blood throughout your body, controls your heart rate and maintains blood pressure.

What is the function of the apex?

The leaf apex is a protruding part of a leaf where water droplets accumulate, and droplet separation occurs during drainage.

What is the role of apex in heart?

The heart sits atop the diaphragm and its apex is close to the anterior surface of the thoracic cavity. With every beat, the heart twists forward and the apex taps against the chest wall, producing the apex beat. This can be felt in the fifth left intercostal space.
