Homeostasis
This is the maintenance of a stable internal environment.
What is Homeostasis?
The nervous system is made up of billions of these.
What are neurons?
This functions to transports gases, nutrients, waste, hormones, and heat
What is blood?
This muscle contracts and relaxes to change lung pressures and facilitate breathing.
What is the diaphragm?
These are chemicals that control/regulate activity of other cells
What are hormones?
This type of feedback mechanism counteracts changes in the body?
What is negative feedback?
This system controls the body's "fight or flight" response.
What is the sympathetic nervous system?
These blood vessels carry blood away from the heart?
What are arteries?
This volume of breath is considered a normal breath.
What is tidal volume?
This is the master gland that governs homeostasis and governs many other endocrine glands.
What is the pituitary gland?
This part of the brain acts as the control center for thermoregulation?
What is the hypothalamus?
This connects the brain and spinal cord. It is responsible for heart beat, breathing, BP, digestion, circadian rhythm
What is the brain stem?
This is the force that the blood exerts on the blood vessels.
What is blood pressure?
What is the alveoli?
This gland releases epinephrine and norepinephrine.
What is the adrenal gland?
This is how the body cools itself.
What is vasodilation and sweating?
This type of neuron carries impulses from receptors in the body to the brain via the CNS?
What is a sensory (afferent) neuron?
This happens during prolonged exercise as heart rate increases to maintain cardiac output.
What is cardiac drift?
This is the leftover air after a full exhale.
What is residual volume?
What are insulin and glucagon?
When glucose levels decrease, this is released to have the liver break glycogen into glucose and raise blood glucose levels.
What is glucagon?
These receptors detect chemicals (scent/taste), detect blood composition (O2, CO2, H+), and send messages to maintain homeostasis.
What are chemoreceptors?
This is how to calculate cardiac output.
What is heart rate x stroke volume?
During exercise, these muscles help breathing rate increase and be more forceful.
What are intercostals?
This hormone causes glycogen storage and fat to be used for energy
What is oestrogen?
