Question

Answer

deoxiginate blood is enters into right atrium then it pours in right ventricle through the valve present in between atrium and ventricle called as atrioventricular valve and then blood is pumped into the left ventricle through semilunar valve...

Answer

Answer

In first deoxygenated blood enter in right atrium and then when pressure is increase in atrium then blood come in ventricle by atrioventricle valve(Bicuspid valve). and then pump by ventricle into blood vessel and semilunar valve prevent of blood back flow.

Answer

The correct answer is option 'B': Atrium, Atrioventricular valve, ventricle, Semilunar valve.

Explanation:
The heart is a complex organ responsible for pumping blood throughout the body. It consists of four chambers - two atria and two ventricles. The blood flow through the heart follows a specific path to ensure efficient circulation.

1. Atrium:
- The blood enters the heart through the superior and inferior vena cava, carrying deoxygenated blood from the body.
- The blood enters the right atrium, which is the first chamber encountered in the heart.

2. Atrioventricular valve:
- From the right atrium, the blood flows through the tricuspid valve, also known as the atrioventricular valve, into the right ventricle.
- The atrioventricular valve prevents the backflow of blood into the atrium when the ventricle contracts.

3. Ventricle:
- The right ventricle receives the blood from the right atrium through the atrioventricular valve.
- The right ventricle contracts, pumping the deoxygenated blood through the pulmonary valve into the pulmonary artery.

4. Semilunar valve:
- The pulmonary artery carries the deoxygenated blood to the lungs, where it picks up oxygen and gets rid of carbon dioxide.
- The oxygenated blood returns to the heart through the pulmonary veins, entering the left atrium.

5. Atrioventricular valve and ventricle:
- From the left atrium, the blood flows through the mitral valve, also known as the atrioventricular valve, into the left ventricle.
- The atrioventricular valve prevents the backflow of blood into the atrium when the ventricle contracts.

6. Semilunar valve:
- The left ventricle contracts, pumping the oxygenated blood through the aortic valve into the aorta.
- The aorta is the largest artery in the body and carries oxygenated blood to all the organs and tissues.

The blood then circulates through the body, delivering oxygen and nutrients and removing waste products. This completes one circuit through the heart.

In summary, the correct path followed by blood on one circuit through the heart is:
Atrium -> Atrioventricular valve -> Ventricle -> Semilunar valve.
