Human Body Systems Study Guide

Front

What is the function of the respiratory system?

Back

The respiratory system moves oxygen (O2) into the body and carbon dioxide (CO2) out of the body.

Front

What is the role of the cardiovascular system?

Back

The cardiovascular system transports blood, which carries oxygen and carbon dioxide, throughout the body.

Front

How do the respiratory and cardiovascular systems work together?

Back

The respiratory system provides oxygen to the blood, while the cardiovascular system transports that oxygen to cells and removes carbon dioxide.

Front

What is homeostasis?

Back

Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions.

Front

What systems are involved in responding to a stimulus?

Back

The nervous, skeletal, muscular, respiratory, and cardiovascular systems all work together to respond to stimuli.

Front

What is the digestive system's role in waste removal?

Back

The digestive system removes solid wastes from the body.

Front

What is the excretory system's function?

Back

The excretory system removes liquid wastes from the body.

Front

How does the respiratory system contribute to waste removal?

Back

The respiratory system removes gaseous waste, primarily carbon dioxide, from the body.

Front

Why does blood circulate throughout the body?

Back

Blood circulates to provide oxygen and nutrients to cells and to remove waste products, helping maintain homeostasis.

Front

What is the relationship between the cardiovascular system and hydraulic systems?

Back

Both systems involve the movement of fluids to provide services; the cardiovascular system moves blood to support body functions, similar to how hydraulic systems use fluid to operate machinery.
