detailed questions and verified
answers all graded A+
What makes the endocrine system different from other
physiological systems? - ✔✔ANSWER ✔✔-It is composed of many
separate glands dispersed throughout the body rather than one
connected structure.
How do endocrine glands function as a coordinated system? -
✔✔ANSWER ✔✔-They all secrete hormones that interact
functionally to regulate body processes.
What is the main role of the endocrine system? - ✔✔ANSWER
✔✔-It regulates body functions using hormones to maintain
homeostasis and control long-term processes.
,How do hormones reach their target tissues? - ✔✔ANSWER ✔✔-
They are secreted directly into the bloodstream and travel to
distant target cells.
Six Major Functions of the Endocrine System - ✔✔ANSWER ✔✔-
What is the first major function of the endocrine system? -
✔✔ANSWER ✔✔-Maintaining a constant internal environment by
regulating metabolism and water/electrolyte balance.
What is the endocrine system's role in stress? - ✔✔ANSWER ✔✔-
It produces adaptive stress responses.
How does the endocrine system affect growth and development?
- ✔✔ANSWER ✔✔-It regulates cell growth, tissue development,
and maturation.
How does the endocrine system regulate reproduction? -
✔✔ANSWER ✔✔-It controls sexual development, gamete
production, and reproductive cycles.
,How does the endocrine system contribute to red blood cell
production? - ✔✔ANSWER ✔✔-It regulates hormones that
stimulate red blood cell formation.
How does the endocrine system integrate with the autonomic
nervous system? - ✔✔ANSWER ✔✔-It helps regulate circulation
and digestive functions.
Hormones - General Concepts - ✔✔ANSWER ✔✔-
What is a hormone? - ✔✔ANSWER ✔✔-A chemical substance
secreted into the blood that exerts effects on distant target
tissues.
Why do hormones act only on specific cells? - ✔✔ANSWER ✔✔-
Only cells with the appropriate receptors can respond to a
hormone.
What determines a hormone's target cell? - ✔✔ANSWER ✔✔-The
presence of specific receptors on the cell.
Hormone Classification - ✔✔ANSWER ✔✔-
, What are the two major categories of hormones? - ✔✔ANSWER
✔✔-Hydrophilic hormones and lipophilic hormones.
What does hydrophilic mean? - ✔✔ANSWER ✔✔-Highly water-
soluble and poorly lipid-soluble.
What does lipophilic mean? - ✔✔ANSWER ✔✔-Highly lipid-
soluble and poorly water-soluble.
Hydrophilic Hormones - ✔✔ANSWER ✔✔-
How do hydrophilic hormones travel in the blood? - ✔✔ANSWER
✔✔-Mostly unbound to carrier proteins.
What types of hormones are hydrophilic? - ✔✔ANSWER ✔✔-
Peptide hormones and most amine hormones.
What are peptide hormones made of? - ✔✔ANSWER ✔✔-Short or
long chains of amino acids.
What are amine hormones derived from? - ✔✔ANSWER ✔✔-
Single amino acid residues.
