Answer:
The pituitary gland controls water balance, growth and blood pressure.
Step-by-step explanation:
The pituitary gland is also called hypophysis, and is a small gland located in the skull that is responsible for secreting hormones and coordinating the activity of other glands.
Hypophysis is usually divided into two portions, adenohypophysis or anterior lobe and neurohypophysis in posterior lobe. Among other functions, the pituitary gland is in charge of
- Water balance and blood pressure, through the antidiuretic hormone or ADH secreted by the neuro-pituitary.
- Growth, through the secretion of growth hormone or GH, secreted by the somatotropic cells of the adenohypophysis.
This gland is also responsible for the secretion of oxytocin and other hormones in charge of regulating endocrine glandular activity.
Regarding the other options:
- Thymus is a gland present in children and related to immune function.
- Thyroid is responsible for secreting hormones that control basal metabolism.
- Pancreas has exocrine and endocrine function, producing digestive enzymes and insulin and glucagon, respectively.
