<h3>What is artery?</h3>

The blood channels that carry oxygen-rich blood from the heart to the body's tissues are called arteries.
Each artery consists of three layers and is a muscular tube bordered by smooth tissue.
The endothelium, a smooth tissue, lines the intima, the inner layer.
Blood is transported from your heart through arteries.
All body parts have arteries, with the exception of the hair, nails, epidermis, cartilages, and cornea.
In the limbs, they run along the flexor surface, where they are less vulnerable to injury, and the larger trunks typically occupy the most protected positions.
A conduit that carries blood from the heart to the body's extremities is called an artery.
Every artery, with the exception of the pulmonary artery, carries oxygenated blood.
The ascending aorta, aortic arch, thoracic aorta, and abdominal aorta are the four divisions of the aorta, which is the biggest artery in the body.

andriy [413]

The nail breathes oxygen to live. The nail breathes the oxygen dissolved in the water.

Given that the aquarium is a small bioma there is not enoguh source of oxygen to replace the oxygen consumed by the snail, except for the oxygen produced by the aquatinc plants inside the aquarium.

Plants produce oxygen through the process named photosynthesis. Photosynthesis requires light.

Given that the aquarium is kept dark, the aquatic plants cannot carry out the process of photosyntthesis and so there will not be generation new oxygen and the snails will die after they do not have oxygen to breath.
