What is the anterior part of heart?

On the right is the medial wall of the right atrium. Anteriorly are the right atrial appendage, the right ventricular outflow tract and the pulmonary trunk. The transverse pericardial sinus separates the back of the aorta from the left atrium and right pulmonary artery.

Anterior refers to the ‘front’, and posterior refers to the ‘back’.

Which heart valve is between the left atrium?

the mitral valve, between the left atrium and left ventricle; and. the aortic valve, between the left ventricle and the aorta.

Which chamber of the heart has the lowest pressure?

Normally the pressure on the right side of the heart and in the pulmonary arteries is lower than the pressure on the left side of the heart and in the aorta. This is because: the right side of the heart pumps blue (deoxygenated – little or no oxygen) blood returning from the body back to the lungs.

What are the two main sides of the heart called?

Your heart is divided into two separate pumping systems, the right side and the left side. The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide.

What are the three key features that will help you to tell the front ventral side of the heart from the back side of the heart?

If you are lucky, the heart will be nicely preserved and you will see that the front (ventral) side of the heart has a couple of key features: 1) a large pulmonary trunk that extends off the top of it 2) the flaps of the auricles covering the top of the atria.

When comparing the left and right halves of a dissected heart How can you determine which is which?

Look closely and on one side you will see a diagonal line of blood vessels that divide the heart. The half that includes all of the apex (pointed end) of the heart is the left side. Confirm this by squeezing each half of the heart. The left half will feel much firmer and more muscular than the right side.

What heart chamber receives blood from the lungs?

The left atrium receives blood from the lungs. This blood is rich in oxygen. The left ventricle pumps the blood from the left atrium out to the body, supplying all organs with oxygen-rich blood.
