Question

Given below is a group of terms, in which the first pair indicates the relationship between the two terms.

Rewrite and complete the second pair on a similar basis.

Example:

Oxygen: Inspiration:: Carbon dioxide: Expiration

Foetus: Amnion:: Heart: ________

Answer 1

1. Amnion: The innermost layer forming the placenta is known as the amnion. It lies in close association with the foetus and protects it from mechanical shocks.
2. Pericardium: Pericardium is the layer that encloses the heart. Just like the amnion, the pericardium prevents the heart from mechanical jerks and decreases the friction between the heart and nearby organs.

Final answer: Foetus:Amnion :: Heart:Pericardium.
