Question

Define the type of circulation observed in animals other than the one shown in the diagram.

Answer 1

Generally two types of circulatory system are observed in organisms i.e. open circulatory system or closed circulatory system.

Complete answer:
The blood circulatory system comprises three self-regulating systems which work in mutual behavior, including cardiovascular system (heart), pulmonary system (lungs), and systemic blood system (arteries, veins etc). The blood circulatory system is accountable for the blood flow, carriage of gases like oxygen and movement of nutrients and hormones to various cells.

The above diagram represents a double circulation type of blood flow system found in the animals. Apart from the above type of blood circulation systems, another type of blood circulation system is found in the animals named as single circulation systems, mostly found in the fishes. The fishes or other animals which possess such a type of circulatory system generally consist of a two-chambered heart with the presence of one ventricle and one atrium. In such a system, the deoxygenated blood is pumped through the heart which further gets oxygenated through the gills and distributed all through the body and finally the deoxygenated blood isolated from the rest body parts goes back to the heart.
Generally, the organisms which consist of an open type of blood circulatory system characteristically have a moderately high volume of hemolymph and lower blood pressure. Some of the examples of organisms having an open type of blood circulatory system include spiders, insects, prawns and others.

Note: Usually, the blood circulatory system is composed of a blood, blood vessels, and the heart, which altogether acts as a network. This network provides the essential components like oxygen, nutrients, hormones, and also eradicates unwanted wastes in the tissues present in the body.
