what do you mean by double circulation ?(According 3 marks) Related:  Double Circulation- Body Fluids and circulation, Biology, Class 11

Answer

In double circulation blood flows through heart twice when it complete single circut in the body  example reptile bird mammal

Answer

*In double circulation,blood circualtes two times through the heart in one cycle of the body....

*there r mainly two types of circulation:-

¥pulmonary circulation

¥systemic circulation

# pulmonary circulation :- circulation of deoxygenated blood from heart to lungs and from oxygenated blood from lungs to heart....

# systemic circulation :- circulation of blood from aorta of heart(oxygenated) to body tissues n.. From body tissues(deoxygenated) to vena cava of heart...

=>double circulation mainly occurs in mammals so as to maintain their body temperature according to environment..

Answer

Double circulation is a process during which blood passes twice through the heart during one complete cycle...

Answer

The type of circulation in which blood moves 2 times through heart is called double circulation

Answer

In human beings, the blood goes through the heart twice during each cycle i.e. the blood passes through the human heart two times to supply once to the whole body. So, it is called Double Circulation of blood.

The double circulation of blood includes

Systematic Circulation: It supplies oxygenated blood from left auricle to left ventricle, thereby pumped to various body parts.

Pulmonary Circulation: The deoxygenated blood is pumped by the right ventricle into the lungs for oxygenation.

Answer

Double Circulation
Double circulation refers to the circulation of blood through two separate circuits in the body, allowing for efficient transport of oxygen and nutrients to tissues and removal of waste products.

Systemic Circulation
- In systemic circulation, oxygen-rich blood is pumped from the heart to the body's tissues and organs through the arteries.
- This oxygen is then delivered to the cells, and carbon dioxide is picked up for removal.
- The deoxygenated blood returns to the heart through the veins to be pumped to the lungs for oxygenation.

Pulmonary Circulation
- Pulmonary circulation is the circulation of blood between the heart and the lungs.
- Deoxygenated blood from the body enters the heart and is pumped to the lungs to pick up oxygen and release carbon dioxide.
- Oxygenated blood returns to the heart to be pumped out to the rest of the body.

Advantages of Double Circulation
- Separation of oxygenated and deoxygenated blood ensures efficient oxygen delivery to tissues and organs.
- Allows for higher blood pressure in systemic circulation, ensuring proper perfusion of tissues.
- Helps maintain a higher metabolic rate and overall efficiency in the body's functions.
In conclusion, double circulation is a vital process in the human body that ensures efficient transport of oxygen and nutrients to tissues while removing waste products. This system allows for the optimization of oxygen delivery and maintains the body's metabolic functions.
