HORMONES AND THE ENDOCRINE SYSTEM PART 2 - QUIZ QUESTIONS



The Thyroid gland 

The Thyroid gland is described as the largest of the endocrine
glands. It is situated in the front of the neck and is butterfly 
shaped. It is controlled by the pituitary gland and secrets two
important hormones: T3 and T4. Iodine is taken from the foods 
we eat and used to produce its hormones.

The hypothalamus produces ADH ( antidiuretic hormone).It is stored
in the posterior pituitary gland. ADH plays a great role in the  amount
of urine which is excreted by the kidneys. 

        Diabetes Insipidus ( DI) should not be confused with Diabetes Mellitus.
       Diabetes Insipidus is caused by a lack of ADH ( antidiuretic hormone).
Surgical intervention may cause this problem.                                

Patients  who develop DI, dump large quantities of dilute urine.
      If left untreated , dehydration may occur.  DDAVP is used to correct
                            the problem.  See above image for more helpful information.
