Question

Name the largest artery in the human body.

Answer 1

Arteries are pressure-filled blood vessels that transport blood away from the heart. With the exception of the pulmonary artery, which delivers deoxygenated blood to the lungs, this blood is typically oxygenated. The systolic pressure, which occurs when the heart contracts, and the diastolic pressure, which occurs when the heart extends and refills, are the two extremes of arterial pressure. The visible pulse that shows cardiac activity is caused by pressure variations inside the artery.

Complete solution:
Aorta is the largest artery in the human body. It carries oxygenated (oxygen-rich) blood from the left ventricle of the heart to the other parts of the body. This process is known as systemic circulation.
There are four parts to the aorta:
1. The ascending aorta is a $2$ inch long artery that rises from the heart. The ascending aorta branches into coronary arteries, which provide blood to the heart.
2. The aortic arch bends above the heart, branching out to supply blood to the head, neck, and arms.
3. The descending thoracic aorta runs through the centre of the chest. The ribs and certain chest tissues receive blood from its tiny branches.
4. The abdominal aorta starts at the diaphragm and splits into two iliac arteries in the lower belly. Branches of the abdominal aorta supply blood to most of the main organs.

Note:
The systemic circulation ensures that all bodily tissues receive enough blood flow. It transports oxygen and nutrients to the cells while also collecting carbon dioxide and trash. The left ventricle pumps oxygenated blood from the arteries to the capillaries in the body's tissues, which is known as systemic circulation. The deoxygenated blood returns through a system of veins to the right atrium from the tissue capillaries.
