Question

When the right ventricle of heart contracts, the blood goes to:

• A. All parts of the body
• B. Pulmonary artery
• C. Aorta
• D. Lungs

Answer 1

The correct option is B Pulmonary artery

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the heart's right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve. When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts. As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery, and to the lungs where it is oxygenated.

So, the correct answer is option D.
