Cellular Respiration and Respiratory System Quiz

What is the function of the nasal cavity in the respiratory system?

• To produce mucus for digestion

• To regulate blood pressure in the lungs

• To cool and dry the air before it enters the lungs

• To warm, moisten, and filter the air before it enters the lungs.

What is the function of the trachea in the respiratory system?

• To transport nutrients to the cells

• To carry air to and from the lungs

• To regulate body temperature

• To help with digestion

What are the bronchi and how do they function in the respiratory system?

• The bronchi are small sacs in the lungs that store air

• The bronchi are located in the heart and assist in pumping blood

• The bronchi are the main branches of the trachea that lead to the lungs and function to carry air to and from the lungs.

• The bronchi are part of the digestive system and help in food digestion

What are alveoli and how are they involved in the exchange of oxygen and carbon dioxide?

• Alveoli are muscles in the chest that help with breathing.

• Alveoli are found in the stomach and aid in digestion.

• Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

• Alveoli are part of the circulatory system and help pump blood.

Describe the role of alveoli in the process of cellular respiration.

• Alveoli regulate blood flow to the heart during cellular respiration

• Alveoli facilitate the exchange of oxygen and carbon dioxide during cellular respiration.

• Alveoli store excess carbon dioxide during cellular respiration

• Alveoli produce energy for cellular respiration

Which body system brings in oxygen molecules from the air?

• Digestive

• Circulatory

• Respiratory

What is oxygen?

• a molecule made of carbon and oxygen atoms

• molecules that are the building blocks of proteins

• a molecule that organisms can use to release energy, and that is made of carbon, hydrogen, and oxygen atoms

• a molecule that organisms get from the air or water around them and use to release energy

What is the chemical reaction between oxygen and glucose that releases energy into cells?

• system

• metabolism

• energy

• cellular respiration
