What is the structure and function of the heart of a fish?

Answer 1

The Heart is a pumping device that pumps blood.

Fish hearts are two chambered, with one ventricle and one auricle. Blood is sent from all over the body to the auricle, which then pumps it to the ventricle, which then pumps it to the gills for oxygenation. From the gills, oxygenated blood is sent to every part of the body. Because blood only goes through the heart once during circulation, we can refer to a fish heart as a single circuit heart.

The fish heart consists of two chambers – an atrium and a ventricle. It pumps deoxygenated blood to the gills for oxygenation and then circulates oxygenated blood throughout the body.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
