Question
Which type of circulation does a human have?
- Open
- Closed
- Semi-open
- None of these
Hint:
Humans consist of a properly organized circulatory system for the transportation of blood.
The correct answer is: Closed
- Humans possess a closed circulatory system.
- The circulatory system refers to the system which carries out the role of transporting blood to all parts of the body. It helps in the transportation of oxygen, nutrients, etc. It also takes part in transporting waste material to the kidneys for excretion.
- A closed circulatory system consists of blood vessels for the transportation of blood. Since, humans consist of the heart, blood, and blood vessels like arteries, veins, and capillaries for this purpose, we can say that we have a closed form of the circulatory system.
The open circulatory system is the one that lacks a proper network of blood vessels for blood transportation.
