ANATOMY

Detailed explanation-1: -Your aorta and pulmonary trunk (arteries) send blood out of your heart. Your pulmonary veins, superior vena cava and inferior vena cava (veins) carry blood into your heart.

Detailed explanation-2: -The left ventricle generates the high pressure needed to pump the blood to your whole body through your blood vessels. When blood leaves the heart to go to the rest of the body, it travels through a large artery called the aorta.

Detailed explanation-3: -Your main pulmonary artery and your aorta are the two great vessels that carry blood out of your heart. A crucial difference is that your pulmonary artery carries oxygen-poor (deoxygenated) blood, while your aorta carries oxygen-rich (oxygenated) blood.

Detailed explanation-4: -The pulmonary artery is located at the exit of the right ventricle. This main arterial branch is located above the heart to the left of the ascending aorta. These vessels go through the connective tissue covering around the heart (pericardium ).

Detailed explanation-5: -Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
