Question

A type of circulatory system in which the blood is pumped out of the heart and the cells & tissues are directly bathed in it is ….(a) Open type
(b) Closed type(c) Single circulation
(d) Double circulation

Answer 1

The correct option is (a) open type.

• In an open circulatory system, blood does not flow through the arterioles, veins and capillaries instead it flows through the cavities. so, blood is circulated out of the heart and the cells and tissues are bathed in it.
• Examples of open circulatory systems are arthropods and molluscs.
• In a closed circulated system, blood flows through blood vessels and the heart.
• In single circulation as in fishes, blood passes from the heart to the gills. purification occurs in gills and after that distributed to other body parts.
• In double circulation, there are two paths for circulation one for oxygenated and the Other for deoxygenated that's why called double circulation. example- mammals

Answer 2

Answer:

The circulatory system in which the blood is pumped out of the heart and the cells & tissues are directly bathed in it is called an open type of circulation.

Explanation:

1. Open circulation takes place while there aren't any vessels to include the blood and it flows freely via the cavities of the body.
2. Closed type of circulation is constituted of the coronary heart that pumps blood into the vessels to attain the tissues and organs. The change of gases withinside the bloodstream takes place among smaller vessels like capillaries and tissues.
3. Single circulation, blood flows simplest that is only once through the coronary heart throughout one whole cycle.
4. Double circulation, blood flows two times via the coronary heart throughout one whole cycle.

so, the circulation in which the blood is pumped out of the heart and cells and tissues are directly bathed in it is called an open type of circulation.
