Gas Exchange

Front

What is gas exchange?

Back

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

Front

What are arteries?

Back

Arteries are blood vessels that carry oxygen-rich blood away from the heart to the body's tissues.

Front

What is the role of veins in the circulatory system?

Back

Veins are blood vessels that carry deoxygenated blood back to the heart.

Front

What is the function of the mitochondrion?

Back

Mitochondria are organelles in cells that produce ATP, the energy currency of the cell, through cellular respiration.

Front

How does the circulatory system interact with the respiratory system?

Back

The circulatory system transports oxygen from the lungs to the body and carries carbon dioxide from the body back to the lungs for exhalation.

Front

What is the primary function of the lungs?

Back

The primary function of the lungs is to facilitate gas exchange, allowing oxygen to enter the blood and carbon dioxide to be expelled.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy molecule used by cells to perform work, including muscle contraction and biochemical reactions.

Front

What is the difference between oxygenated and deoxygenated blood?

Back

Oxygenated blood is rich in oxygen and is carried from the lungs to the body, while deoxygenated blood is low in oxygen and is returned to the lungs.

Front

What is the role of capillaries in the circulatory system?

Back

Capillaries are tiny blood vessels where the exchange of oxygen, carbon dioxide, nutrients, and waste occurs between blood and tissues.

Front

What is the transport system in the human body?

Back

The transport system includes the circulatory system, which consists of the heart, blood vessels, and blood, facilitating the movement of substances throughout the body.
