homeostasis and receptors/chp 1

The outcome is the opposite of the stimulas

Negative feedback loop

Increases/amplifies the stimulus

Positive feedback

This brings signals towards the control center also the 3rd stage in homestasis

Afferent signal

This signal send a sign to an effector from the control center

Efferent signal

This picks up the change during homestasis of balance

Receptor 3rd stage

Mechanoreceptors

Touch/pressure

Chemoreceptors

Chemical

Thermreceptors

Temperature

Photoreceptors

Light

Nocicioceptors

Pain

the bodies ability to maintain an constant internal environment even with external environmental changes

homeostasis

homeostasis is continuously monitoring and adjustments this makes it dynamic or static

DYNAMNIC

name all the basic survival needs of the human body

oxygen water nutrients and atmospheric pressure, body temp

name all the things homeostasis regulates in the human body

pH levels, temperature, blood pressure, fluid balance, glucose concertation in blood, waste management, electrolyte levels

what are the essential body functions

maintaining boundaries, movement, responsiveness or excitability, digestion, metabolism, exertion, reproduction, growth

what does water do for the body

keeps mucosal membranes moist, allows body cells to grow and reproduce and survive, flushes body waste, lubricates joints.
