Question

Draw the schematic diagram of the circulatory system of a human and label the following parts- i)heart ii) aorta iii) capillaries iv) vena cava.

Answer 1

Circulatory system:

1. The circulatory system of the human body has two halves.
2. The pulmonary circuit, which runs between the heart and lungs, contains two distinct circuits and requires that blood pass through the heart twice.
3. The heart and the other organs are connected by a systemic circuit.
4. The double circulation circulatory system present in humans is shown in the diagram below.
5. The labels are displayed as shown in the illustration.

1. Heart

• The heart is a hollow muscle organ.
• Your cardiovascular system includes your heart and blood arteries.
• Your blood vessels are supplied with blood by your heart.
• All of your body's parts receive oxygen and nourishment through the blood.

2. Aorta:

• It is the body's biggest artery.
• It transports blood that is oxygenated out from the heart and into the rest of the body.

3. Capillaries:

• In practically every portion of the body, a capillary joins an arteriole (small artery) and a venule (small vein) to create a network of blood vessels.
• Capillaries are involved in the interchange of fluids and gases between tissues and the blood, and their thin, permeable cell walls allow for this to happen.
  4. Vena cava:
• A sizable vein that transports blood from different parts of the body to the heart.
