Question

what are the two circuits by which the gases are circulated in and out of the lungs?​

Answer 1

Answer:

There are two distinct but linked circuits in the human circulation called the pulmonary and systemic circuits. The pulmonary circuit transports blood to and from the lungs, where it picks up oxygen and delivers carbon dioxide for exhalation.

Answer 2

Pulmonary circuit and Systematic circuit

Explanation:

Blood vessels

• In the human body, the blood vessels are divided into two functional circuits they are the pulmonary circuit and the systemic circuit.

• The right ventricle serves as the pump for the pulmonary circuit, which circulates blood through the lungs.

• The left ventricle acts as a pump for the systemic circuit, which supplies blood to the body's tissue cells.

Pulmonary circuit

• Pulmonary circulation transmits oxygen-depleted blood from the right ventricle to the lungs for replenishment. Then, oxygenated blood flows to the left atrium.

Systematic circuit

• The systemic circulation ensures that adequate blood supply is provided to all body tissues. It delivers oxygen and nutrients to every cell while also picking up carbon dioxide and waste.
• Systemic circulation occurs when the left ventricle pumps oxygenated blood from the arteries to the capillaries in the body's tissues.
• The deoxygenated blood returns to the right atrium of the heart via a network of veins originating in the tissue capillaries.
