Question

From which part of the human heart does the largest artery arise?
A) Left ventricle
B) Right ventricle
C) Left atrium
D) Right atrium

Answer 1

Hint: The arteries are the blood vessels, which deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined by smooth tissue. It has three layers. They are – The intima, The media, and The adventitia.

Complete answer:
The largest artery is the aorta, which is the main high-pressure pipeline. It starts at the top of the left ventricle. The heart pumps blood from the left ventricle into the aorta by the aortic valve. Three leaflets on the aortic valve open and close with every heartbeat to allow one-way blood flow.
A) Left ventricle –Aorta starts at the top of the left ventricle. So it is the correct option.
B) Right ventricle – it is the wrong option.
C) Left atrium – The left atrium receives the oxygenated blood from the left and right pulmonary veins. So it is the wrong option.
D) Right atrium – it is also a wrong option.

The correct option is A) left ventricle.

Note: The aorta is a tube that is over an inch in diameter. The aorta is divided into four parts.
At the starting, the aorta goes upwards as the ascending aorta then soon after arches laterally to the left. which form the arch of the aorta. After this, the aorta continues falling as the descending aorta up to it splits into its terminal branches.
The aorta is the chief artery in the body whose important function is to transfer oxygenated blood from the heart to the rest of the body.
It is very important to remember that all the arteries of the human body (exclude the pulmonary arteries) receive blood from the aorta.
