Respiratory + Circulatory Systems Review

Front

What are the two body systems that primarily interact in the alveoli?

Back

Respiratory and circulatory systems.

Front

What is the main function of the circulatory system?

Back

To transport nutrients to the cells and carry wastes away from the cells.

Front

What causes muscle fatigue and cramping after exercise?

Back

Wastes (like lactic acid) build up in the muscles because not enough oxygen can get to the muscles.

Front

What materials does the circulatory system transport throughout the body?

Back

Glucose, oxygen, carbon dioxide, and wastes.

Front

What is the role of the heart in the circulatory system?

Back

To pump blood throughout the body.

Front

What are the main components of the circulatory system?

Back

Heart, blood vessels, and blood.

Front

How does oxygen enter the bloodstream?

Back

Through the alveoli in the lungs during respiration.

Front

What is the primary function of the respiratory system?

Back

To take in oxygen and give off carbon dioxide.

Front

What is the relationship between the respiratory and circulatory systems?

Back

The respiratory system provides oxygen to the blood, and the circulatory system transports it to the body's cells.

Front

What is lactic acid and how is it related to exercise?

Back

Lactic acid is a waste product that builds up in muscles during intense exercise when oxygen is scarce.
