What is the purpose of insulin and glucagon in our body?
It instructs target cells in the liver and muscles to absorb glucagon so that the amount circulating in the blood drops back to a normal level.
It instructs target cells in the pancreas to absorb glucose so that the amount circulating in the blood drops back to a normal level.
It instructs target cells in the liver and muscles to absorb glucose so that the amount circulating in the blood drops back to a normal level.
It instructs target cells in the liver and muscles to absorb glucose so that the amount circulating in the blood increases to a higher level.
What does Antidiuretic Hormone (ADH) do?
when water content in the blood is high, the brain produces more ADH, and a high volume of water is re-absorbed by the kidney along with only a small volume of concentrated urine released, so that the water content can adjust back having normal water content within the blood.
when water content in the blood is low, the brain produces more ADH, and a high volume of water is re-absorbed by the kidney along with only a small volume of concentrated urine released, so that the water content can adjust back having normal water content within the blood.
when blood sugar levels are low, the brain produces more ADH, and a high volume of water is re-absorbed by the kidney along with only a small volume of concentrated urine released, so that the water content can adjust back having normal water content within the blood.
when blood sugar levels are high, the brain produces more ADH, and a high volume of water is re-absorbed by the kidney along with only a small volume of concentrated urine released, so that the water content can adjust back having normal water content within the blood.
A negative feedback loop is when a change in a system causes another change that brings the system back to its starting position, therefore maintaining homeostasis.
TRUE
FALSE
Which system is faster?
Endocrine System
Digestive system
Nervous system
Synapse system
What does the central nervous system (CNS) consist of?
The nerves that branch out from the brain and spinal cord.
Bundles of nerves outside the brain and spinal cord
Brain and Spinal Cord
What is the pituitary gland known as?
nervous gland
endocrine gland
pineal gland
master gland
What does the pituitary gland do?
secretes hormones to regulate many metabolic processes, including growth and energy expenditure.
To receive information about the state of the light-dark cycle from the environment and convey this information to produce and secrete the hormone melatonin.
To produce and release several hormones that help carry out important bodily functions.
Produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.

What does the law of conservation of mass state?
Why do the endocrine glands have blood vessels coming out from them?
As a way of connecting all glands together so they can communicate with the nervous system
To be able to send chemical messages (hormones) to and from target cells and the nervous system.
To send motor neurons to target cells in specific glands
This is how they get their energy
