Body Systems Review

Front

What is the primary function of the respiratory system?

Back

The primary function of the respiratory system is gas exchange, which involves supplying oxygen to the blood and removing carbon dioxide from it.

Front

Which two body systems are primarily responsible for gas exchange and transport?

Back

The circulatory system and the respiratory system are responsible for gas exchange and transport between the body and the environment.

Front

How does the respiratory system support the circulatory system?

Back

The respiratory system delivers oxygen to the circulatory system, which is essential for transporting oxygen to cells throughout the body.

Front

How does the circulatory system support the respiratory system?

Back

The circulatory system brings waste gases, such as carbon dioxide, to the lungs and exchanges them for oxygen.

Front

What is the role of the cardiovascular system?

Back

The cardiovascular system is responsible for transporting blood, nutrients, gases, and waste products throughout the body.

Front

Define gas exchange in the context of the respiratory system.

Back

Gas exchange is the process by which oxygen is taken into the body and carbon dioxide is expelled, occurring in the alveoli of the lungs.

Front

What are alveoli?

Back

Alveoli are tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be removed.

Front

What is the significance of oxygen in the human body?

Back

Oxygen is essential for cellular respiration, a process that produces energy for cells to function.

Front

What is carbon dioxide's role in the body?

Back

Carbon dioxide is a waste product of cellular respiration that must be removed from the body to maintain pH balance and prevent toxicity.

Front

Explain the relationship between the respiratory and circulatory systems.

Back

The respiratory system provides oxygen to the blood, while the circulatory system transports that oxygen to cells and brings carbon dioxide back to the lungs for exhalation.
