________ caries blood from right ventricles to lungs.

  1. Superior vena cava

  2. Inferior vena cava

  3. Pulmonary arteries

  4. Pulmonary veins
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The pulmonary artery is a blood vessel which delivers impure blood from right ventricles to lungs for the oxygenation. Pulmonary artery begins from the base of the right ventricle. As it leaves the heart it divides into two branches left and right pulmonary artery. The left and right branches bring their de-oxygenated blood to the corresponding left and right lungs.
So, the correct answer is 'Pulmonary arteries'.

The pulmonary artery carries deoxygenated blood from the ........... to the lungs.

  1. Left ventricle

  2. Right ventricle

  3. Left auricle

  4. Right auricle

B Correct answer
Explanation

Pulmonary circulation carries blood to and from the lungs. They include the pulmonary artery (aorta) and its branches to the capillaries in the lungs, as well as the veins, that drain those capillaries. The pulmonary arteries carry blood low in oxygen from the right ventricle, while the pulmonary veins carry blood high in oxygen from the lungs into the left atrium. This circuit functions to eliminate carbon dioxide from the blood and replenish its supply of oxygen.

So, the correct answer is option B.

Which of the following statement is correct regarding humans?

  1. Arteries always carry oxygenated blood while veins always carry deoxygenated blood

  2. Arteries. are provided with valves while veins are devoid of valves

  3. Arteries always carry blood away from the heart, while veins always carry blood towards the heart

  4. Venous blood is returned to the left ventricle

C Correct answer
Explanation

Arteries carry blood oxygenated blood away from the heart. While the veins carry deoxygenated blood towards the heart.

Pulmonary artery carries deoxygenated blood to the lungs for oxygenation. Pulmonary vein brings oxygenated blood to heart. 
So, the correct answer is option C.

Body receives blood through arteries. Which one is out of place?

  1. Aorta

  2. Renal artery

  3. Coronary artery

  4. Pulmonary artery
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. Aorta is the largest artery in body which supplies blood from heart to rest of the body parts.
B. Renal arteries are blood vessels that branch from abdominal aorta and supply blood to the kidneys.
C. Coronary arteries supply the oxygenated blood to heart.
D. Pulmonary artery carries deoxygenated blood from right ventricle to the lungs. 
Hence, body receives blood through arteries except the lungs which receive deoxygenated blood through pulmonary artery.
So, the correct answer is 'Pulmonary artery'.
