MICROANATOMY

Detailed explanation-1: -In single circulation, the blood passes through a single circuit – where blood is pumped by the heart to the gills for oxygenation, after which the blood flows to the rest of the body and back to the heart.

Detailed explanation-2: -Single circulation examples For example, birds, fish, reptiles, and other species share a single circulatory system. Blood goes from the heart to the gills, where it is cleaned before being dispersed to various parts of the body in a single circulatory system.

Detailed explanation-3: -Fishes have single circulation. They have a two-chambered heart comprising an atrium and a ventricle. In fishes, the heart pumps out the deoxygenated blood which undergoes oxygenation in the gills. The oxygenated blood is then passed to the body parts from where the deoxygenated blood is returned to the heart.

Detailed explanation-4: -Fishes have a single circulation type. It has two chambers that have only a single atrium and a single ventricle. The blood from all the body parts collects into the atrium and the ventricles. The atrium collects the deoxygenated blood in a single atrium and pumps it out through a ventricle.

Detailed explanation-5: -In single circulation, blood flows to and from the heart through a single pathway, whereas in double circulation there are two separate pathways that are connected to the heart through which oxygenated and deoxygenated blood flows.
