Homeostatic Mechanisms

Back

help to keep a relatively constant internal environment in organisms

Front

Which of these conditions indicate positive feedback has occurred?

• The production of a particular product continues its production
• The production of a particular product stops its production
• Sweat evaporates from a person's skin

Back

The production of a particular product continues its production

Front

Which of these conditions indicate negative feedback has occurred?

• The production of a particular product continues its production
• The production of a particular product stops its production
• Sweat evaporates from a person's skin

Back

The production of a particular product stops its production

Osmoregulation happens when organisms regulate:

temperature

,

blood glucose

,

oxygen

,

water and solutes

Back

water and solutes

Front

Thermoregulation happens when organisms regulate:

temperature

,

blood glucose

,

oxygen and carbon dioxide

,

water and solutes

Back

temperature

Front

Gas exchange occurs to regulate:

temperature

,

blood glucose

,

oxygen and carbon dioxide

,

water and solutes

Back

Diabetes is a disease where some mammals cannot properly regulate

Back

blood glucose

Front

When blood glucose levels get too high, the pancreas stimulates the release of:

glucose

,

glycogen

,

insulin

,

glucagon

Back

insulin

Front

If mammals get too warm, their blood vessels

Back

dilate to release heat more easily

Front

If mammals get too cold, their blood vessels

Back

constrict to prevent heat loss
