The answer is <span>B. contains enzymes that begin the breakdown of proteins.
Saliva is watery substance secreted by salivatory glands. <em>It cleanses the mouth</em> and maintenance oral hygiene. <em>It moistens the food</em>, so the created food bolus could easier pass into the esophagus. It also <em>carries food chemicals to taste receptors</em> so they can be tested. It contains enzymes involved in the food digestions.

The thyroid is an endocrine gland that regulates metabolic function through the production of all of the following hormones except: Thyroliberin.
Thyrotropin is a peptide secreted by the anterior pituitary gland that prompts the thyroid gland to release thyroxine. It is also known as thyroliberin and thyroid-stimulating hormone (TSH) Thyrotropin-releasing factor, a peptide located in the hypothalamus of the brain and affecting glandula thyroidea secretion, acts to cause the release of TSH.
In vivo, thyrotropin controls thyroid development favourably. The gland becomes hypoplastic in its absence, either as a result of a pituitary disorder or as a side effect of thyroid hormone therapy, with a reduction in the quantity and size of thyrocytes.
