HUMAN RESPIRATORY SYSTEM QUIZ - G7

What are the lungs responsible for?

• Filtering air before it enters the body.

• Exchanging oxygen and carbon dioxide during breathing.

• Pumping blood throughout the body.

• Breaking down glucose for energy.

What are alveoli?

• The windpipe that carries air to the lungs.

• Tiny air sacs in the lungs where gas exchange occurs between air and blood.

• The muscles that facilitate breathing.

• The main branches of the trachea.

What is a bronchus?

• The diaphragm muscle used for breathing.

• One of the two main branches of the trachea that lead into the lungs.

• Small air passages that branch off from the bronchi.

• The organ responsible for oxygen production.

What is the function of the trachea?

• To exchange gases in the lungs.

• To filter, warm, and moisten air.

• To carry air from the throat to the lungs.

• To support the rib cage during breathing.

What is the nasal cavity responsible for?

• Producing energy for cells.

• Filtering, warming, and moistening air as it enters the respiratory system.

• Transporting blood to the lungs.

• Performing gas exchange with alveoli.

What role does the diaphragm play in breathing?

• It helps in gas exchange.

• It separates the chest from the abdomen and facilitates inhalation and exhalation.

• It carries oxygenated blood to the body.

• It filters the air in the nasal cavity.

What are bronchioles?

• The tiny air sacs where gas exchange occurs.

• Small air passages that branch off from the bronchi and lead to the alveoli.

• The main airway leading to the lungs.

• The muscles that assist in respiration.

What is the respiratory system responsible for?

• The distribution of nutrients throughout the body.

• The intake of oxygen and the removal of carbon dioxide from the body.

• The filtration of blood in the kidneys.

• The production of hormones in the endocrine system.

What does gas exchange refer to?

• The process of filtering air in the nasal cavity.

• The transfer of oxygen from inhaled air to the blood and removal of carbon dioxide from the blood to exhale.

• The absorption of nutrients in the intestines.

• The movement of blood through the pulmonary circulation.

What is diffusion in the context of the respiratory system?

• The process of filtering air through the nasal cavity.

• The movement of molecules from an area of higher concentration to an area of lower concentration, crucial for gas exchange in the lungs.

• The pumping of blood by the heart.

• The breakdown of glucose in the mitochondria.
