Class 11 Zoology simulations · Body Fluids and Circulation

Double circulation

Follow red blood cells through the pulmonary circuit (heart–lungs) and the systemic circuit (heart–body).

Open the simulation

What to notice

Oxygenated and deoxygenated blood never mix in the human four-chambered heart.

Key relation

Right ventricle → lungs → left atrium ; left ventricle → body → right atrium

Try this

Highlight the pulmonary circuit: which vessel carries deoxygenated blood away from the heart?

What you can change

• Highlight: choose Both circuits, Pulmonary circuit, Systemic circuit
• Heart rate: 50 to 150 beats/min

More in Body Fluids and Circulation

• Blood groups and transfusion
• The cardiac cycle
• Electrocardiogram (ECG)
