Circulatory and Respiratory Review

Air moves into the body in this order:

Mouth/nose - trachea - bronchioles - bronchi - alveoli-capillaries

• True

• False

What gas moves out of the alveoli and into the surrounding capillaries?

• carbon dioxide

• oxygen

• glucose

• waste

Imagine a capillary that runs through your skin. What will move out of the capillary and into your skin cells?

• just oxygen

• just carbon dioxide

• carbon dioxide and waste

• oxygen and glucose

What is the function of the respiratory system?

• to carry oxygen and glucose to all the cells of the body

• to bring oxygen into the body from the atmosphere, and release carbon dioxide into the atmosphere

• to break down food into monomers like glucose for cellular respiration

• to bring carbon dioxide into the body from the atmosphere, and release oxygen into the atmosphere

What is the function of the circulatory system?

• to bring oxygen and nutrients to cells, and to remove carbon dioxide and waste from cells

• to break down food into monomers so that it can be used for cellular respiration

• to bring carbon dioxide and waste to cells, and to remove oxygen and nutrients from cells

• to bring oxygen into the body from the atmosphere, and to release carbon dioxide into the atmosphere

What is the name of the strong muscle that contracts, pulling air into the lungs?

• Bronchi

• Alveoli

• Heart

• Diaphragm

What does the epiglottis do?

• it prevents food from going down the trachea

• it pulls air into the lungs

• it is where O2 enters the blood, and CO2 exits the blood

• It is a small sac at the end of a bronchiole

Where are alveoli found?

• In the lungs, at the end of a bronchiole

• In the arteries, exchanging glucose and waste

• In the heart, preventing blood from flowing the wrong way

• In your nose, filtering out dust and other particles

Where do arteries carry blood?

• Toward the mouth and nose

• Toward the heart

• Away from the heart

• Away from the mouth and nose

What is the arrow pointing to on the heart?

• right atria

• right ventricle

• left atria

• left ventricle
