Question

Arteries are best defined as the vessels which
(a) Supply oxygenated blood to different organs
(b) Carry blood away from the heart to different organs
(c) Break up into capillaries which reunite to form a vein
(d) Carry blood from one visceral organ to another visceral organ

Answer 1

Hint: These blood vessels are muscle tubes that deliver oxygen-rich blood. In this process, the blood passes two times through the heart in one cycle. The circulatory system of humans (higher vertebrates) is divided into two separate systems of circuits, the systemic circuit, and the pulmonary circuit.

Complete answer:
Arteries are the vessels which carry blood away from the heart to different organs. The human circulatory system is a double circulatory system and is composed of the heart and a system of blood vessels (arteries, veins, and capillaries).
The circulation of oxygenated blood starts from the left auricle followed by the left ventricle. It distributes nutrients and oxygen to body parts. Blood is pumped out of the heart into arterioles through arteries (blood vessels which are muscular tubes lined by smooth tissue) of decreasing size, which merge before reaching the sites of exchange with the capillaries. Blood leaving the capillaries is gathered into venules and then veins before returning to the heart. Also, the left side (left auricle and left ventricle) provides pressure to propel blood to the entire body.
So, the correct answer is ‘Carry blood away from the heart to different organs’.

Note: Very tiny blood vessels that help to connect arteries and veins are known as capillaries and their primary function is to facilitate the exchange of elements between your blood and tissues. A very small blood vessel, especially one collecting blood from the capillaries is known as venule. They range from 7μm to 1mm in diameter and it allows blood to return from the capillary beds to drain into the veins.
