Question

Which of the following is TRUE about the third trimester of pregnancy? (A) The fet grows the least during this trimester. (B) It is the period during which the embryo differentiates and develops its vario organ systems. (C) The fet needs large amounts of calcium, iron, and protein from the mother's diet. (D) It is the period during which the placenta becomes well established.

Answer 1

(D) It is the period during which the placenta becomes well established.

Step-by-step explanation:

The third trimester of pregnancy is the period during which the placenta, which is an essential organ for supplying nutrients and oxygen to the fetus and removing waste products, becomes well established and fully functional. During this trimester, the fetus also experiences significant growth, and many of its organ systems continue to develop and mature. Additionally, the fetus may require increased amounts of nutrients, including calcium, iron, and protein, from the mother's diet during the third trimester, but this need is not exclusive to this trimester, as nutritional requirements are important throughout pregnancy.
