Learn: Mechanisms of Homeostasis

What is the role of a receptor in helping an organism maintain homeostasis?

It detects a stimuli and sends a message to the control center

Homeostasis directly relates to...

Stability

List 3 examples of a positive feedback loop:

Blood clotting, childbirth, and fruit ripening.

Internal control systems maintain homeostasis by regulating which of these?

External conditions

On a hot day, which of these is an outward sign that thermoregulation is taking place?

Sunburn

In simple words, how does the liver help to regulate glucose levels in the blood?

It stores extra glucose as glycogen when levels are high and releases it back into the blood when levels are low.

The body works to maintain homeostasis in response to what conditions?

Changing internal and external conditions.

What is the most important thing for an organism to maintain homeostatis?

Behaviors and negative feedback

The body's internal environment must stay...

Stable

The long-term effects of a disruption of homeostasis include...

Destruction of organ systems

What is Osmoregulation and how does it help sea fish maintain homeostasis?

It balances water and salt. Sea fish drink seawater and pump out excess salt through gills.

The human body is made of different systems. Explain and provide an example of how a problem with one system would affect other body systems.

Interconnected systems rely on each other. If the lungs fail, the heart cannot deliver oxygen, damaging all organs.

Indentify an example of an animal behavior that is used to maintain homeostasis in response to an external factor.

A lizard basking in the sun to warm its body temperature when the weather is cold.

How is a sudden storm at sea like a virus? Use the word homeostasis in your explanation.

Both are external threats. A storm disrupts the ship's stability just like how a virus disrupts the body's homeostasis.

A crew tries to keep a sailing ship on course despite all the changes in the sea and in the weather. How is the crew like the internal control systems in the human body?

The crew monitors change and adjusts the ship to stay on course.
