Transcript of Endocrine System
College of Lake County
i) the endocrine system
helps control many of the slow physiological processes in the body, such as growth, reproduction & metabolism
ii) what are the 8 main endocrine glands (nongonadal), where are they & what are the main functions of their hormones in relation to growth and metabolism?
Course Learning Objectives &
C. Describe the basic ways that materials move within & between cells.
E. Describe the various organ systems (i.e., endocrine) within the human body & explain their basic functions.
L. Identify the major endocrine glands, the primary hormones produced by each, & the function of those hormones.
Compare & contrast an endocrine gland & it's hormone(s) adapted for influencing metabolism with a gland with hormones specialized for growth.
Evaluate the role of endocrine glands in helping maintain homeostasis in the body.
Diagram an interaction between one endocrine gland & another, such as two glands with antagonistic hormones.
How do hormonal imbalances arise? Infer what would happen if a particular endocrine gland malfunctioned, by producing too much hormone, or not enough.
Regulation of Blood Pressure Objectives:
- local/hormonal/neural mechanisms operate both short & long term
- the web of interactions between these
mechanisms & their effects on blood
- what factors increase peripheral
resistance in blood vessels & what is the
effect on blood pressure ?
Comparison of Terms:
Vasomotion (2 parts) affects
blood vessels = increased peripheral
blood vessels = decreased peripheral
(i.e., standing up & sitting right back down!)
(i.e., fainting in the shower or hot tub!)
= short term
that regulate blood pressure by
altering blood volume
via the kidneys operate in a web
= work together
have opposing actions
Corticotropin Releasing Hormone (CRH) Renin Angiotensins I/II
Adrenocorticotropic Hormone (ACTH)
Antidiuretic Hormone (ADH)
More Review Terms:
other organs/tissue to release their
Negative Feedback Loops
end product inhibits its own production
Main Long Term Hormonal Blood Pressure Regulators
Why is this objective important to know?
Our group activities stress one of the
primary causes of death in medical centers:
What are the sources, target tissues/organs,
& effects of these hormones?
Red Marrow hematocytoblasts
(blood cell stem cells)
Retention of Na+ leads to
retention of H20 by
