1QQ # 4: Answer one.1. Starting with a drop in blood pressure, diagram the
sequence of events that begins with the secretion of renin and ends with responses that act to restore blood pressure toward normal.
2. A) What gland is the source of Thyrotropin Releasing Hormone? B) What are the target cells of TRH? C) How does TRH get to its target cells (be specific.) D) What do the target cells of TRH do when stimulated by TRH? E) How is the secretion of TRH affected as the concentration of T4 increases?
Thyroid Gland
• TH =T3 and T4
Fenestrated Capillary(typical of endocrine glands)
S1
Synthesis, Storage and Secretion of T3 and T4Roles of TSH (Thyroid Stimulating Hormone)
TH increases cell metabolism & heat production (BMR)
