Module 07 - Homeostasis Review

Front

What is thermoregulation?

Back

Thermoregulation is the process by which organisms regulate their body temperature to maintain a stable internal environment.

Front

What happens to blood vessels in mammals when they get too cold?

Back

Blood vessels constrict to prevent heat loss.

Front

What is a hypotonic solution?

Back

A hypotonic solution is one where the concentration of solutes outside the cell is lower than inside, causing water to flow into the cell.

Front

What is the primary function of urine production by the kidneys?

Back

To get rid of excess water, salts, and other wastes.

Front

What body system controls and coordinates all body activities through electric impulses?

Back

The nervous system.

Front

What is homeostasis?

Back

Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in external conditions.

Front

What role does the endocrine system play in homeostasis?

Back

The endocrine system regulates bodily functions through hormones, helping to maintain homeostasis.

Front

What is the difference between isotonic, hypertonic, and hypotonic solutions?

Back

Isotonic solutions have equal solute concentrations inside and outside the cell; hypertonic solutions have a higher concentration outside, causing the cell to lose water; hypotonic solutions have a lower concentration outside, causing the cell to gain water.

Front

How do organisms respond to overheating?

Back

Organisms may sweat or increase blood flow to the skin to release heat.

Front

What is the significance of feedback mechanisms in homeostasis?

Back

Feedback mechanisms help regulate physiological processes by providing information about changes in the internal environment.
