Homeostasis/Body Systems/Biomolecules

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What are the three types of muscles in the human body?

Back

The three types of muscles are skeletal, smooth, and cardiac.

Front

Which bodily functions are regulated by homeostasis?

Back

Homeostasis regulates body temperature, blood sugar, and blood pH, but not body movements.

Front

What is the role of insulin in blood sugar regulation?

Back

Insulin is released when blood sugar levels are high, helping to lower blood sugar by facilitating its uptake into cells.

Front

How is the human body organized from smallest to largest unit?

Back

The human body is organized as follows: cell, tissue, organ, system, body.

Front

What is the function of skeletal muscles?

Back

Skeletal muscles are responsible for voluntary movements and are attached to bones.

Front

What is the function of smooth muscles?

Back

Smooth muscles control involuntary movements in organs such as the intestines and blood vessels.

Front

What is the function of cardiac muscles?

Back

Cardiac muscles are specialized muscles found in the heart that control involuntary contractions to pump blood.

Front

What is a feedback loop in homeostasis?

Back

A feedback loop is a biological mechanism that helps maintain homeostasis by responding to changes in the internal environment.

Front

What happens when body temperature drops?

Back

When body temperature drops, the body responds by shivering to generate heat and increase body temperature.
