stimulates the growth of bones and soft tissues
stimulates breast development and milk production in mammary glands
increases the concentration of calcium in the blood
secreted when the body encounters stresses
reduces the concentration of calcium in the blood
plays a role in childbirth by stimulating contractions of the uterus

1. prolactin (prl)
2. calcitonin
3. epinephrine
4. oxytocin
5. thyroxine (t4)
6. growth hormone (gh)
7. parathyroid hormone (pth)

Explanation:

• Thyroxine (\(T_4\)) is known to increase the metabolic rate.
• Growth hormone (\(GH\)) stimulates the growth of bones and soft tissues.
• Prolactin (\(PRL\)) is responsible for stimulating breast development and milk production in mammary glands.
• Parathyroid hormone (\(PTH\)) increases the concentration of calcium in the blood.
• Epinephrine is secreted when the body encounters stresses.
• Calcitonin reduces the concentration of calcium in the blood.
• Oxytocin plays a role in childbirth by stimulating contractions of the uterus.

Answer:

• increases the metabolic rate: 5. thyroxine (\(T_4\))
• stimulates the growth of bones and soft tissues: 6. growth hormone (\(GH\))
• stimulates breast development and milk production in mammary glands: 1. prolactin (\(PRL\))
• increases the concentration of calcium in the blood: 7. parathyroid hormone (\(PTH\))
• secreted when the body encounters stresses: 3. epinephrine
• reduces the concentration of calcium in the blood: 2. calcitonin
• plays a role in childbirth by stimulating contractions of the uterus: 4. oxytocin
