Secondary Endocrine Organs

Question 1

Secondary endocrine organs

Answer 1

• Ovaries (development of oocyte)
• Testes (development of sperm)
• Thymus (immune)
• Heart (pumping blood)
• Gastrointestinal tract (digestion)
• Adipose tissue (energy reserve)
• Kidneys (water/electrolyte balance)
• Liver (detoxification)
• Skeleton (support)

Question 2

Which hormones do the ovaries produce?

Answer 2

Oestrogen, progesterone and inhibin

Question 3

Oestrogens
(e.g.
estradiol)

Answer 3

Targets ovary, uterus, breast, bone marrow and hypothalamus. Promotes maturation of female reproductive organs. Stimulates the development of secondary female characteristics. Regulates the menstrual cycle

Question 4

Progesterone

Answer 4

Targets ovary, uterus, breasts, bone marrow and hypothalamus. Promotes implantation of the embryo, maintains pregnancy and regulates the menstrual cycle.

Question 5

Inhibin.

Answer 5

Targets the anterior pituitary gland, inhibits secretion of follicle stimulating hormone

Question 6

Testes

Answer 6

Testosterone and inhibin

Question 7

Testosterone

Answer 7

Targets testes, bone marrow and muscle. Stimulates bone and muscle growth. Stimulates the development of secondary male characteristics. Promotes maturation of male reproductive organs. Promotes sperm production

Question 8

Thymus

Answer 8

Produces thymosins which targets thymus and white blood cells. Promotes development and maturation of white blood cells, especially T lymphocytes

Question 9

Which hormones does the heart produce?

Answer 9

Atrial natriuretic peptide ( produced by atria) and brain natriuretic peptide (produced by ventricles)

Question 10

Atrial and brain natriuretic peptide

Answer 10

Atrial produced by atria and brain produced by ventricles. Targets kidney. Reduces sodium and water retention which decreases blood pressure.

Question 11

Which hormones does the gastrointestinal tract produce?
