Question

question 12 (1 point)
the right ventricle pumps ______ into the ______.
oxygen poor blood; pulmonary trunk
oxygen poor blood; aorta
oxygen rich blood; aorta
oxygen rich blood; superior vena cava
question 13 (1 point)
what is true about the hormone that is released from the organ that the arrow is pointing at?

Explanation:

For Question 12, the right ventricle pumps de - oxygenated (oxygen - poor) blood to the lungs via the pulmonary trunk. The aorta receives oxygen - rich blood from the left ventricle, and the superior vena cava brings de - oxygenated blood to the right atrium.
For Question 13, since the organ is not shown (the arrow and the organ are not described), we cannot answer it. But for Question 12, the correct knowledge about the heart's blood - pumping function is used for answering.

Answer:

Question 12: oxygen poor blood; pulmonary trunk
Question 13: No answer due to lack of information about the organ indicated by the arrow.
