CHAPTER 8 RESPIRATORY SYSTEMS IN HUMAN AND ANIMALS #BIOBIASA

Based on the diagram, what is the function of structure X that ensure the insects receive adequate amount of oxygen?

• Filter the air that flows into the trachea

• Select the air that flows into the trachea

• Allows the air to flow into the trachea

• Inhibit the air to flow into the trachea

In what forms are the carbon dioxide being transported in the blood?

• I and III

• I and IV

• II and III

• III and IV

What happen to structure X and Y during inhalation?

• X : Moves downwards and inwards Y : Contracts

• X : Moves upwards and outwards Y: Contracts

• X : Moves downwards and inwards Y : Relaxes

• X : Moves upwards and outwards Y : Relaxes

Why does the gaseous exchange become less efficient for an emphysema patient?

• Excessive amount of mucus is produced inside the alveoli

• The surface area pf the alveoli is reduced

• The walls of the alveoli are less moist

• The walls of the alveoli become swollen and thick

Which of the following characteristics refers to the respiratory structure?

• The lining surface is thin

• The surface is always moist

• Rich with blood capillaries

• Numerous numbers of structure so that the total surface area is also large

Which of the following statements is correct about the human respiratory structure and its adaptations?

• Large number of trachioles to provide a large amount of surface area for absorption of respiratory gases

• Extensive blood capillary network to accelerate the transportation of respiratory gases

• The walls of the respiratory structure are thick to facilitate gas diffusion

What would happen to our breathing if the alveoli were damaged and poorly functioning?

• Sneeze often

• Gasping

• Persistent cough

• Difficult to swallow

What is the respiratory surface for the organism shown in diagram 6?

• Trachiole

• Skin

• Alveolus

• Filament

WHich of the following situation causes maximum diffusion of oxygen from X to Y?

• X : High partial pressure of oxygen Y : Low partial pressure of carbon dioxide

• X : Low partial pressure of carbon dioxide Y : High partial pressure of oxygen

• X : High partial pressure of oxygen Y : High partial pressure of carbon dioxide

How does this device help to treat disease X?

• This device can reduce inflammation and widen the path in bronchiole tube and ease the air flow

• This device increase total surface area of alveolus to increase the gaseous exchange

• This device reduces mucus production and prevent infection
