What does your body do with excess hormones?
Stores them in the liver
Excretes them in urine
Sends them to the brain
Excretes them through the lungs
What is the endocrine system?
A system of vessels that circulates blood around the body.
A group of bones and tissue that provides support and structure for the body.
A group of glands that work together with the nervous system to coordinate all body functions
A group of organs that is responsible for eliminating wastes.
What is the main function of the endocrine system?
It secretes chemicals, or hormones, that are sent around the body to maintain balance = homeostasis.
It creates electrical messages that are sent around the body to maintain balance = homeostasis.
It maintains the correct level of oxygen in the body
It releases waste from the body.
The adrenal glands release adrenaline to help the body regulate _________________.
diseases
body temperature.
stress.
hormones.
The response to stress is called
Stay or Stray Response
Fight or Stay Response
Flee or Stray Response
Fight or Flight Response
Which term refers to the body's use of energy for energy and growth?
Excretion
Metabolism
Digestion
Respiration
Hormone regulation mostly operates under which type of feedback mechanism?
positive feedback
negative feedback
zero feedback
Hormones are not regulated
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

Respiratory rate increases.
Blood becomes thicker.
What effect would the secretion of anti-diuretic
hormone (ADH) have on osmoregulation?

FSH (follicle stimulating hormone) stimulates the production of gametes (sex cells) in both males and females.
True
Fals
This hormone stimulate two target tissues during and after childbirth (parturition) - smooth muscle in the uterus and muscle cells in the lactating breast. It stimulates more forceful contractions as labour progresses and stops soon after the baby is delivered (a POSITIVE feedback loop)
Oxytocin
Prolactin

muscle contraction
transmission of nerve impulses
