The pulmonary artery carries 

biology transport in mammals cardiac cycle heart, blood vessels and cardiac cycle human heart

  1. Deoxygenated blood to the lungs

  2. Oxygenated blood to brain

  3. Oxygenated blood to the lungs

  4. Deoxygenated blood to the kidney

Show answer
Correct Option: A
Explanation:
  • Blood enters the heart through two large veins, the inferior and superior vena cava brought from different parts of the body.
  • This oxygen-deficient blood from the body is emptied into the right atrium of the heart which is further pumped to the right ventricle. 
  • As the right ventricle contracts, blood is pumped into the pulmonary artery and to the lungs where it is oxygenated.
  • Thus, the pulmonary arteries carry deoxygenated blood from the right ventricles to the lungs. So, the correct answer is 'Deoxygenated blood to the lungs'.

Fill in the blanks with suitable words given below:
The_______ artery takes the blood from the ventricles to the lungs.

  1. Serum

  2. Fibrinogen

  3. Hemoglobin

  4. Pulmonary

  5. Sphygmomanometer

  6. Ventricles

Show answer
Correct Option: D
Explanation:

The pulmonary artery is the artery that carries blood from the right ventricle of the heart to the lungs for oxygenation. It is involved in the pulmonary circulation of the cardiovascular system.

Hence, the correct answer is 'Pulmonary'.

In human foetus, the heart begins to beat at developmental age of

biology transport in animals cardiac cycle heart, blood vessels and cardiac cycle human heart

  1. $4$ week

  2. $3$ week

  3. $6$ week

  4. $8$ week

Show answer
Correct Option: A
Explanation:

During $3$ to $4$ weeks of gestation, the heart usually starts beating in human foetus.

So, option A is the correct answer.

Choose the correct answer from the alternatives given.
Blood travels from heart to lungs byway of the:

biology transport in mammals cardiac cycle heart, blood vessels and cardiac cycle human heart

  1. Pulmonary artery

  2. Pulmonary vein

  3. Anterior vena cava

  4. Posterior vena cava

Show answer
Correct Option: A
Explanation:

  • Pulmonary artery and the Pulmonary vein are a set of blood vessels that are related to the lungs. 
  • The Pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation, this oxygenated blood is carried back to the heart by the Pulmonary vein for systemic circulation i.e. for ​circulation to different parts of the body.
So, the correct option is 'Pulmonary artery'.
