Question

How does placenta act as an endocrine gland?

Answer 1

Endocrine Gland:

• Endocrine glands are the ductless gland that secret their hormones directly into the blood rather than the ducts.
• Examples:

1. Pituitary Gland - Growth hormone and prolactin are secreted by this gland.
2. Thyroid Gland - Thyroxin and calcitonin are secreted by this gland.

Placenta as an Endocrine Gland:

• A disc-shaped connection between mother and embryo is known as the placenta.
• The placenta functions as an endocrine gland too, secreting the following hormones:

1. During pregnancy Human chorionic gonadotropin is produced.
2. During pregnancy, Human placental lactogen is produced.
3. Progesterone
4. Estrogens

• As a result of the increased production of these hormones during pregnancy, the mother experiences metabolic changes that support foetal growth.
