GCU BIO202 EXAM 1 (ENDOCRINE AND BLOOD)
STUDY GUIDE ACTUAL VERIFIED QUESTIONS
& CORRECT ANSWERS UPDATED 2025
Practice questions for this set
Terms in this set (96)
negative feedback A primary mechanism of homeostasis, whereby a change
in a physiological variable that is being monitored triggers
a response that counteracts the initial fluctuation.
direct pathway hormones are exchanged across gap junctions of cells, such
as the intercalated discs of the heart. This maintains
homeostasis within a specific tissue set, rather than sending
it to other organ tissue or all across the body.
Paracrine pathway hormones are produced in a cell, secreted, and act directly on
nearby receptive cells
endocrine pathway hormones are produced in a cell, secreted, and travel through
blood vessels to distant cells, attach to receptors, and act on
that cell
Hormones chemical messengers that are manufactured by the
endocrine glands, travel through the bloodstream, and
affect other tissues

, Glands Organs or tissues in the body that create chemicals that
control many of our bodily functions
target cells cells that have receptors for a particular hormone
hormone receptor a protein in or on the cell that binds to the hormone and
initiates cellular mechanisms
free hormones Remain functional for less than 1 hour Diffuse out
of bloodstream:
bind to receptors on target cells
Are broken down and absorbed: by
cells of liver or kidney
Are broken down by enzymes:
in plasma or interstitial fluids
Protein bound hormones hormones that remain in the bloodstream for long amounts
of time. The glands secrete them in abudance, but they are
only released when the other proteins run out i.e. steroid
hormones
with water soluble hormones- they bind to a receptor and
hormone amplification
cAMP takes over to produce more of a specific hormone
water soluble hormones (all amino acid-based hormones except thyroid hormone)
Act on plasma membrane receptors
Act via G protein second messengers
Cannot enter cell
lipid soluble hormones -steroid and thyroid hormones
-act on intracellular receptors that directly activate genes
-can enter cell
adenohypophysis anterior pituitary gland
