What is asthma and how does it affect the respiratory system?

• Asthma is a condition where airways become inflamed and narrowed, making breathing difficult.

• Asthma is a disease that only affects the digestive system.

• Asthma is a condition where the heart pumps blood more rapidly.

• Asthma is a disorder that causes bones to become brittle.

What are the four steps of gas exchange in the lungs?

• Inhalation, diffusion of oxygen into blood, diffusion of carbon dioxide into alveoli, exhalation.

• Inhalation, oxygen binds to hemoglobin, carbon dioxide is absorbed, exhalation.

• Inhalation, oxygen is exhaled, carbon dioxide is inhaled, exhalation.

• Inhalation, oxygen is converted to carbon dioxide, carbon dioxide is converted to oxygen, exhalation.

What is the order of the structures that air travels through to get to the lungs in the body?

• Nose/Mouth → Pharynx → Larynx → Trachea → Bronchi → Lungs.

• Nose/Mouth → Larynx → Pharynx → Trachea → Bronchi → Lungs.

• Nose/Mouth → Trachea → Pharynx → Larynx → Bronchi → Lungs.

• Nose/Mouth → Bronchi → Trachea → Larynx → Pharynx → Lungs.

What are the six functions of the digestive system?

• Ingestion, propulsion, mechanical digestion, chemical digestion, absorption, elimination.

• Ingestion, respiration, circulation, excretion, absorption, elimination.

• Filtration, propulsion, mechanical digestion, chemical digestion, absorption, elimination.

• Ingestion, propulsion, mechanical digestion, filtration, absorption, elimination.

What are the six functions of the respiratory system?

• Breathing, gas exchange, sound production, olfaction (smell), protection, and regulation of blood pH.

• Digestion, absorption, excretion, circulation, movement, and reproduction.

• Vision, hearing, taste, touch, balance, and coordination.

Label the small intestine, large intestine, liver, stomach, teeth, tongue, pancreas and gall bladder. These are key digestive organs.

• Small and large intestines absorb nutrients/water; liver processes nutrients; stomach digests; teeth and tongue aid mechanical digestion; pancreas and gall bladder release enzymes and bile.

• Small and large intestines produce bile; liver digests food; stomach absorbs nutrients; teeth and tongue release enzymes; pancreas and gall bladder store water.

• Small and large intestines filter blood; liver stores water; stomach produces bile; teeth and tongue absorb nutrients; pancreas and gall bladder aid mechanical digestion.

• Small and large intestines break down proteins; liver absorbs water; stomach filters blood; teeth and tongue store bile; pancreas and gall bladder digest carbohydrates.
