answer the questions
What is your favorite gland of the endocrine system? Why? What hormone(s) does it produce? Chose one of those hormone and answer the following: what type of hormone is this (peptide, etc…) and what is the basic mechanism of action (target cell, receptor location, signaling cascade…). How is this hormone regulated (releasing and inhibiting hormones) and how are the levels / concentrations of this hormone regulated in the blood? Lastly, what are the systemic consequences of producing too much and too little of this hormone, and how does the body compensate for this? (im choosing pancreas and the hormone is insulin )
2. Choose ONE WB cell within either innate or acquired immunity. What is the main function of this cell, and where does it originate? Trace its lineage and explain why is this cell unique relative to the overall immune response. To better illustrate the cellular function, choose either inflammation / infection / injury scenario and highlight the role of your cell. Finally, explain what role this cell plays in cross-talk between innate and acquired arms of your immune system. (I want to choose monocyte)
3. What is the function and evolutionary importance of the small intestine during digestion? Providing 3 distinct evolutionary examples of either small intestine or analogous structures and explain, in sufficient detail, nutrient absorption efficacy for each.
( 3 unique species that absorb food in a different structure than small intestine but works like small intestine “ same function as small intestine” )
4. Liver of large organ with impressive regenerative capabilities. Why is liver so important? What type of enzymes are produced there (provide three examples); what are the stages in liver disease that subsequently provoke scarring, and how is the liver function recovered? Since liver is the vital organ, a person with the complete liver failure needs a transplant, yet this is one of the most complicated medical procedures. Why?
5) what is Hashimoto disease, and how it is connected(effects) to other hormones in our body ( insulin, glycogen, estrogen, oxytocin, thyroid hormones, dopamine, ….)

1. The endocrines system significant role in the body is to regulate mood, the growth, development, metabolism and reproductive processes. The pancreas gland is my most favorite gland of the endocrine system which is positioned on the upper abdomen which also serves two purposes. It helps in food digestion and also in the production of hormones that serve mainly to control levels of blood sugar.
