Practice Flashcard Cellular Respiration/Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain a stable, constant condition, despite changes in the external environment.

Front

Which body system is primarily responsible for maintaining homeostasis?

Back

The nervous system is primarily responsible for maintaining homeostasis by sending signals to various parts of the body to respond to changes.

Front

What hormone is secreted by the pancreas when blood glucose levels are low?

Back

Glucagon is the hormone secreted by the pancreas when blood glucose levels are low, signaling the liver to release glucose into the bloodstream.

Front

What is hypoglycemia?

Back

Hypoglycemia is a condition characterized by abnormally low blood glucose levels, which can lead to symptoms like dizziness, confusion, and fainting.

Front

What is glycogen?

Back

Glycogen is a polysaccharide that serves as a form of energy storage in animals, primarily found in the liver and muscles.

Front

What is the opposite of hypoglycemia?

Back

Hyperglycemia is the condition characterized by abnormally high blood glucose levels.

Front

What is the role of the excretory system in homeostasis?

Back

The excretory system helps maintain homeostasis by removing waste products and excess substances from the body, regulating water and electrolyte balance.

Front

Define the term 'set point' in the context of homeostasis.

Back

The set point is the ideal value or range that the body tries to maintain for a particular physiological variable, such as temperature or blood glucose levels.

Front

What is the significance of the circulatory system in homeostasis?

Back

The circulatory system is significant in homeostasis as it transports nutrients, gases, hormones, and waste products throughout the body, helping to maintain stable internal conditions.

Front

What does the term 'stable' mean in relation to homeostasis?

Back

In relation to homeostasis, 'stable' refers to the ability of an organism to maintain a consistent internal environment despite external changes.
