Single circulation system:
1. In a single circulation system, blood flows through the heart only once during each complete circuit of the body.
2. This system is found in fish and some invertebrates.
3. Blood is pumped from the heart to the gills where it picks up oxygen, then flows to the rest of the body before returning to the heart.
4. The blood pressure is lower in a single circulation system compared to a double circulation system.
Double circulation system:
1. In a double circulation system, blood flows through the heart twice during each complete circuit of the body.
2. This system is found in mammals, birds, and reptiles.
3. There are two separate circuits - pulmonary circulation (blood flows from the heart to the lungs and back) and systemic circulation (blood flows from the heart to the rest of the body and back).
4. The blood pressure is higher in a double circulation system compared to a single circulation system.

Single Circulation System
- Found in invertebrates like earthworms, insects, and mollusks.
- Blood flows through the body once per cycle.
- Blood is pumped from the heart to the tissues and organs, where it collects waste products.
- The waste-carrying blood then returns directly to the heart.
Double Circulation System
- Found in vertebrates (fish, amphibians, reptiles, birds, and mammals).
- Blood flows through the body twice per cycle.
Pulmonary Circulation
- Blood is pumped from the heart to the lungs.
- In the lungs, blood picks up oxygen and releases carbon dioxide.
- Oxygenated blood returns to the heart.
Systemic Circulation
- Blood is pumped from the heart to the rest of the body.
- In the tissues and organs, blood delivers oxygen and collects waste products.
- Waste-carrying blood returns to the heart.
Key Differences
- Number of circuits: Single circulation has one circuit, while double circulation has two circuits.
- Function of pulmonary circuit: In double circulation, the pulmonary circuit purifies the blood by exchanging oxygen and carbon dioxide.
- Oxygen delivery: In double circulation, oxygenated blood is delivered to the tissues and organs.
- Waste removal: In double circulation, waste-carrying blood is returned to the heart for purification.
- Efficiency: Double circulation is more efficient at delivering oxygen and removing waste because it separates the oxygenation and distribution of blood.
