Explanation:

For Question 15: The intrinsic conduction system of the heart includes the sinoatrial (SA) node, atrioventricular (AV) node, and bundle branches. The atrioventricular (AV) valve is a structure for preventing back - flow of blood, not part of the conduction system.
For Question 16: The foramen ovale is a connection between the two atria in the fetal heart, allowing blood to bypass the non - functional fetal lungs.

Answer:

Question 15: atrioventricular (AV) valve
Question 16: connect the two atria in the fetal heart
