What is the main function of the respiratory system?

• to provide oxygen and remove carbon dioxide from the body

• o break down food and absorb nutrients

• to remove oxygen from the body and deliver carbon dioxide

What is the function of the bronchi?

• Transport air from nose to lungs
• Transport air from trachea to lungs
• Transport air from lungs to alveoli
• Transport air from alveoli to blood

What is the name of the movement of oxygen in and carbon dioxide out of the body.

• transpiration

• respiration

• digestion

• ventilation

The chemical reaction which releases energy using oxygen and glucose and creates carbon dioxide and water as waste products

• transpiration

• respiration

• digestion

• ventilation

Tiny air sacs in the lungs that are the site of gas exchange between the lungs and blood.

• alveoli​
• relax
• diaphragm​
• nose

The trachea...

• extends from the nasal cavity to the bronchi
• is lined with cilia
• lies posterior to the esophagus
• is the passageway for food into the stomach

The actual gas exchange with the blood occurs in the

• bronchioles
• alveoli
• ventricles

Which organelle uses oxygen to release energy from nutrient molecules?

• nucleus

• ribosome

• mitochondria

• endoplasmic reticulum

The movement of oxygen from the alveoli to the blood and from the blood to the tissues is due to the process of... 

• osmosis
• diffusion
• cytokinesis
• phagocytosis

When the diaphragm contracts...

• the volume of the thoracic cavity increases and the pressure decreases, causing air to rush into the lungs.
• the volume of the thoracic cavity decreases and the pressure increases causing air to rush out of the lungs.
