Answer 1

answer :

33) c: pancreas

The pancreas is unique in that it's both an endocrine and exocrine gland .

In other words ,the pancreas has the dual function of secretung hormones into blood ( endocrine ) and secreting enzymes through ducts ( exocrine ) .

34) b ) TRH>TSH>thyroid hormone

Thyroid releasing hormone from the hypothalamus stimulates TSH from the pituitary ,which stimulates thyroid hormone release .

35) c ) outer ear

The ceruminous glands are specialized sudoriferous glands located subcutaneously in the external auditory canal ,in the outer 1/3 .

Ceruminous glands are simple ,coiled tubular glands made up of an inner secretory layer of cells and outer myoepithelial layer of cells .

36) d) cells may down regulate when hormone levels rises.
