Understanding Respiratory Processes

What is the process of gas exchange in the lungs called?

• Filtration

• Osmosis

• Diffusion

• Evaporation

Which part of the respiratory system is primarily responsible for gas exchange?

• Bronchi

• Trachea

• Lungs

• Alveoli

What gas do we inhale that is essential for our body?

• Hydrogen

• Oxygen

• Carbon Dioxide

• Nitrogen

What gas do we exhale that is a waste product of respiration?

• carbon dioxide

• oxygen

• hydrogen

• nitrogen

What is the main function of the alveoli in the lungs?

• The main function of the alveoli is to enable gas exchange between the air and the bloodstream.

• To filter out dust and particles from the air.

• To produce mucus for lubrication in the lungs.

• To regulate blood pressure in the pulmonary circulation.

How does oxygen enter the bloodstream from the lungs?

• Oxygen enters the bloodstream through diffusion from the alveoli into the capillaries.

• Oxygen is transported by red blood cells from the stomach.

• Oxygen enters the bloodstream via the trachea directly.

• Oxygen is absorbed through the skin into the bloodstream.

What is the role of the diaphragm in the breathing process?

• The diaphragm only helps with exhalation.

• The diaphragm is responsible for digestion.

• The diaphragm has no role in breathing.

• The diaphragm contracts to facilitate inhalation and relaxes for exhalation.

What are the two main types of respiration?

• Photosynthesis and fermentation

• Oxidative phosphorylation and glycolysis

• Cellular respiration and combustion

• Aerobic respiration and anaerobic respiration

How does the structure of the lungs facilitate gas exchange?

• The structure of the lungs is solid, preventing any gas exchange.

• The structure of the lungs, with millions of alveoli and thin walls, facilitates efficient gas exchange.

• Gas exchange occurs primarily in the trachea due to its large surface area.

• The lungs are filled with liquid to enhance gas exchange.

What happens to the body when there is a lack of oxygen?

• The body becomes more efficient at using oxygen.

• The body suffers from hypoxia, leading to potential organ damage and life-threatening conditions.

• The body adapts by producing more red blood cells.

• The body experiences increased energy levels.
