Solution:

#### Riddle 1:
> I am the vanishing gland. You need me most during your early childhood years and I begin to disappear when you reach puberty. I am considered a member of both the endocrine and the lymphatic system. I secrete a hormone, which helps to stimulate lymphoid cells to produce T-cells. You need me to help fight off diseases.

- Key Clues:
- Vanishes during puberty.
- Part of both the endocrine and lymphatic systems.
- Produces hormones that stimulate lymphoid cells to produce T-cells.
- Involved in fighting diseases.

- Answer: Thymus

#### Riddle 2:
> I control how “sweet” you are. I keep your blood sugar within normal limits. If your blood sugar is too high, I produce insulin, and if it is too low, I produce glucagon. I also play a role in the digestion process.

- Key Clues:
- Controls blood sugar levels.
- Produces insulin (lowers blood sugar) and glucagon (raises blood sugar).
- Involved in digestion.

- Answer: Pancreas

#### Riddle 3:
> You can thank me for all those muscles you have and that deep voice. I am also the reason you need to shave every day. I play a role in reproduction by allowing you to make sperms.

- Key Clues:
- Responsible for muscle development.
- Causes deep voice and facial hair growth.
- Involved in sperm production.

- Answer: Testis (male)

#### Riddle 4:
> They say “good things come in small packages” and that is true with me. I am very tiny, but I do a lot of jobs in the endocrine system. I help you grow and develop. I also provide the milk for a new mother to breast-feed her baby. The back part of me helps maintain your body’s water balance. Finally, when I release my hormone, oxytocin, will cause the uterus to contract so a new life can be born.

- Key Clues:
- Very small but has many functions.
- Helps with growth and development.
- Produces prolactin for lactation.
- Releases oxytocin for uterine contractions during childbirth.
- Involves water balance regulation.

- Answer: Pituitary

#### Riddle 5:
> Many people say I am shaped like a butterfly. I increase metabolism and influence both physical and mental activity. I help with tissue growth. I also cause calcium to be stored in bones.

- Key Clues:
- Butterfly-shaped.
- Increases metabolism.
- Influences physical and mental activity.
- Helps with tissue growth.
- Involves calcium storage in bones.

- Answer: Thyroid

#### Riddle 6:
> There are two of me in your body and I have two parts. I help keep your electrolytes balanced by deciding how much sodium and potassium your body needs. I also play a role in pain control. I am a good friend of the sympathetic nervous system and I play a role in preparing your body to handle emergencies. I help you decide whether to “fight or flight!”

- Key Clues:
- Two glands in the body.
- Regulates electrolytes (sodium and potassium).
- Involved in pain control.
- Associated with the "fight or flight" response.
- Sympathetic nervous system connection.

- Answer: Adrenal

#### Riddle 7:
> Many say I resemble a “pine cone.” I am stimulated by the amount of light that enters your eyes. Many believe I help prevent the early onset of puberty. I produce a hormone, which causes your body temperature to drop and relax to fall asleep.

- Key Clues:
- Resembles a pine cone.
- Stimulated by light entering the eyes.
- May delay puberty.
- Produces a hormone that promotes sleep (melatonin).

- Answer: Pineal
