Question

The largest artery in the human body is
A) Systemic artery
B) Lingual artery
C) Pulmonary artery
D) Aorta

Answer 1

Hint:Arteries are blood vessels which transport oxygen rich blood from the heart to various tissues of the body. It is a muscular tube which is lined by smooth tissues.

Complete answer:
Let us know a little about arteries before we find the correct answer. Arteries have three layers and they are thick, muscular and rigid. They have high oxygen and low carbon dioxide in them.

>Option A: Systemic arteries are involved in carrying oxygenated blood from the heart to various parts of the body. But they are not the largest artery. Therefore, this is the incorrect option.
>Option B: Lingual artery is a branch of the external carotid artery and it is the artery that is involved in supplying the gingiva, tongue, etc. But they are not the largest artery. Therefore, this is the incorrect option.
>Option C: Pulmonary artery is involved in carrying deoxygenated blood from the right ventricle to the lungs. But they are not the largest artery. Therefore, this is the incorrect option.
>Option D: Aorta is the main artery which is involved in carrying blood away from the heart to various parts of the body. The blood travels through the aortic valve once it leaves the heart and then travels through the aorta. It starts at the left ventricle of the heart, and then extends upwards into the chest forming an arch. It is also the largest artery found in the body. Therefore, this is the correct option.

Thus, the correct option is (D) Aorta.

Note:The arteries are involved in carrying the blood away from the heart and it is further divided into smaller vessels known as arterioles which is further divided into small capillaries. The major function of arteries is carrying pure and oxygenated blood throughout the body.
