Why double circulation is necessary in human beings.?

Question

Answer

In multicellular organism like human the energy requirement for processing life process is high to meet such huge energy requirement it is important to separate oxygenated and deoxygenated blood which can be only get by using double circulation system and double circulation takes place which is also required for maintaining body temperature.

Answer

During a single cycle blood goes twice in the heart which is known as double circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.

Answer

Double Circulation in Human Beings
Double circulation is a crucial feature of the human circulatory system that ensures efficient distribution of oxygen and nutrients throughout the body. It consists of two separate circuits - pulmonary circulation and systemic circulation.

Pulmonary Circulation
- In pulmonary circulation, deoxygenated blood from the body is pumped to the lungs for oxygenation.
- The oxygenated blood then returns to the heart to be pumped out to the rest of the body.

Systemic Circulation
- Systemic circulation involves the distribution of oxygenated blood to all tissues and organs of the body.
- Deoxygenated blood is returned to the heart to be sent to the lungs for reoxygenation.

Importance of Double Circulation
- Efficient oxygenation: Double circulation ensures that blood is adequately oxygenated in the lungs before being distributed to the body, providing cells with the oxygen they need for energy production.
- Separation of oxygenated and deoxygenated blood: By keeping oxygenated and deoxygenated blood separate, double circulation prevents the mixing of these two types of blood, which could compromise oxygen delivery.
- Optimal nutrient delivery: The systemic circulation delivers nutrients and removes waste products from cells, maintaining a healthy cellular environment.
- Maintenance of blood pressure: The two circuits work together to maintain proper blood pressure throughout the body, ensuring that tissues receive adequate blood flow.
In conclusion, double circulation is necessary in human beings to ensure efficient oxygenation, nutrient delivery, waste removal, and maintenance of blood pressure. It is a vital component of the complex circulatory system that sustains life in humans.
