77
Q

Sodium 135-146 mmol/L

Chloride 98-110mmol/ L

79
Q

Organ systems roles in homeostasis

Nervous system
Cardiovascular system
Muscular system
Integumentary system
Endocrine system
Digestive system
A

Nervous system: the hypothalamus in the brain contains the bodys “thermostat”

Cardiovascular system: blood vessels constrict to conserve heat

Muscular system: the muscles contract to cause shivering, which generates heat

Integumentary system: sweat production steps and goos bumps for which creates an insulating layer

Endocrine system: thyroid hormone production increase metabolism which raises body temp

Digestive system: the metabolism of food and stored fat generates heat

80
Q

3 parts if homeostasis regulation

A

1) receptor- receives info about a change in the environment
2) control centre- receives and processes info from the receptor
3) effector- responds to signals from the control centre by either opposing or enhancing the stimulus

81
Q

Define feedback

A

The signal sent by the effector

It can either be positive or negative

82
Q

Define Negative feedback

A

When the effector opposes the stimulus (such as dropping temp) and reverses the direction of change (causing temp to rise)

83
Q

Define postive feedback

A

When the effector reinforces the stimulus (such as uterine contractions during childbirth which trigger the release of the hormone oxytocin) and amplifies the direction of change (causing even greater contractions and further release of oxytocin)

84
Q

Do most systems operate by negative or positive feed back?

A

Negative

Only a few situation where positive feedback is beneficial such as blood clotting and child birth

More often positive feed back is harmful
