What is the main function of the endocrine system?
It creates chemicals, or hormones, that are sent around the body to maintain homeostasis.
It maintains the correct level of oxygen in the body to maintain homeostasis.
It creates electrical messages that are sent around the body to maintain homeostasis.
It releases waste from the body to maintain homeostasis
Which of the following are chemicals that travel in the blood and cause changes in different parts of the body?
hormones
glands
adrenal glands
parathyroid
Symptoms often associated with diabetes are
excessive thirst
fatigue
frequent urination
all of these
Feedback loops are important because they allow organisms and the environment to
change based on new inputs
fall apart
change based on new outputs
maintain balance
What hormone stimulates the thyroid gland?
ADH
ACTH
TSH
GH
What hormone prolongs and intensifies the sympathetic response during stress by increasing heart rate and raising blood glucose?
Epinephrine
Glucocorticoid
ADH
T3 & T4
What hormone increases the amount of water absorbed by the kidneys thereby decreasing urine amount?
calcitonin
mineralocorticoids
ADH
ACTH
What hormone lowers blood glucose levels?
glucocorticoids
glucagon
aldosterone
insulin
Growth Hormone goes with?
posterior pituitary
anterior pituitary
pineal gland
thymus
increase reabsorption of water by kidney
ACTH
PTH
ADH
glucagon
Development of immune system
adrenal glands
parathyroid
testes
thymus
Produces male sex characteristics
ovaries
testes
hypothalamus
thymus
Which hormone regulates water balance by reducing the amount of water leaving the body
aldosterone
ADH
GH
thyroxine
Calcitonin decreases calcium in the blood while Parathyroid hormone works antagonistically. What is the function of PTH (Parathyroid Hormone)?
To increase the amount of calcium in the blood so that it is available for the bones
To decrease the amount of calcium in the blood so that it is available for the bones
To break down bones to release calcium into the blood
to build up bones
How do the hormones get around the body?
Through the skeletal system
Through the digestive system
Through the circulatory system
Through the respiratory system
Which of the following best describes endocrine system?
"ductless' system
"duct" system
sweat
tears
Which of the following best describes exocrine system?
"duct" system
"ductless" system
GH
ADH
Which of the following best fits the hypothalamus?
influenced by TSH
influenced by LH
serves as the body's link between the nervous & endocrine system
stimulates melanocytes
Which best describes how the endocrine system maintains homeostasis?
never wants to use feedback mechanisms
uses ovaries or testes to balance
By signaling for more adreanline
By signaling the body to respond to internal and external stimuli and by using feedback mechanisms.
Which description best fits non-steroid hormone acting on a target cell?
hormone binds to receptors on the cell membranes, activating an enzyme on the inner surface of the cell membranes. This enzyme activates a second messenger.
hormones, which are made of lipids, move across the cell membranes of target cells.
Once inside, a steroid hormone binds to a steroid receptor protein, forming a hormone-receptor complex
none of these are correct
Which description best fits steroid hormone acting on a target cell?
hormone binds to receptors on the cell membranes, activating an enzyme on the inner surface of the cell membranes. This enzyme activates a second messenger.
hormones, which are made of lipids, move across the cell membranes of target cells.
The second messenger then activates or inhibits cell activities
adrenaline very much plays a role
If a steroid hormone-receptor complex was not able to enter the nucleus of a cell, how would this affect the cell’s activities?
The cell would be able to respond to the hormone.
The cell would not be able to respond to the hormone.
The cell would go find another cell.
None of these are correct
