Fill in the Blank

During 'Menghembus nafas', the diaphragm ___ and curves upwards.

Open Ended

Describe how the respiratory system contributes to maintaining homeostasis in the human body.

Multiple Choice

Why is the respiratory system essential for human survival?

• It helps in digestion of food

• It provides oxygen to the body and removes carbon dioxide

• It controls body temperature

• It produces hormones

Fill in the Blank

The process of breathing involves two main actions: ___ and ___ air.

Multiple Choice

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

• It filters air entering the lungs.

• It contracts and relaxes to change the volume of the thoracic cavity, aiding in breathing.

• It produces mucus to trap dust particles.

• It transports oxygen in the blood.

Open Ended

Describe the main function of alveolus in the human respiratory system.

Multiple Choice

Which of the following is NOT a component of the human respiratory system?

• Epiglottis

• Bronkiol

• Alveolus

• Kidney

Multiple Choice

Which of the following structures is the correct sequence for the passage of air during inhalation in humans?

• Lubang hidung → Rongga hidung → Farinks → Larinks → Trakea → Bronkus → Bronkiol → Alveolus

• Lubang hidung → Farinks → Rongga hidung → Larinks → Trakea → Bronkus → Bronkiol → Alveolus

• Lubang hidung → Rongga hidung → Larinks → Farinks → Trakea → Bronkus → Bronkiol → Alveolus

• Lubang hidung → Rongga hidung → Farinks → Larinks → Bronkiol → Bronkus → Trakea → Alveolus

Open Ended

Explain how the pressure concept shown in the diagram relates to the process of breathing in humans.

Multiple Choice

What is the main difference between 'Menarik nafas' and 'Menghembus nafas' in the breathing mechanism?

• Menarik nafas involves air entering the lungs, while Menghembus nafas involves air leaving the lungs.

• Menarik nafas involves the diaphragm relaxing, while Menghembus nafas involves the diaphragm contracting.

• Menarik nafas increases thoracic pressure, while Menghembus nafas decreases thoracic pressure.

• Menarik nafas is only possible during sleep, while Menghembus nafas occurs during exercise.

Multiple Choice

Which of the following actions occur during 'Menarik nafas'?

• Intercostal muscles contract and pull the rib cage upwards and outwards.

• Diaphragm relaxes and curves upwards.

• Thoracic cavity volume decreases.

• Air pressure inside the lungs becomes higher than outside.

Open Ended

Explain the role of the diaphragm during the process of 'Menarik nafas'.

Multiple Select

Which structures are directly involved in the movement of air during breathing?

• Trachea

• Diaphragm

• Peparu (lungs)

• Sangkar rusuk (rib cage)

Open Ended

Describe the sequence of events that leads to air entering the lungs during inhalation.

Multiple Choice

What happens to the diaphragm during exhalation?

• It contracts and moves downward

• It relaxes and curves upward

• It expands and flattens

• It remains unchanged

Multiple Select

Which of the following changes occur during inhalation?

• Intercostal muscles contract

• Rib cage moves up and out

• Diaphragm relaxes

• Thoracic cavity volume increases

Multiple Choice

During exhalation, what causes air to be pushed out of the lungs?

• Decrease in thoracic cavity volume

• Increase in air pressure inside the lungs

• Relaxation of the diaphragm

• All of the above

Fill in the Blank

The epiglottis closes the ___ during swallowing to prevent food from entering the airway.

Multiple Choice

Which gases are involved in the exchange process in the human respiratory system?

• Oxygen and nitrogen

• Oxygen and carbon dioxide

• Carbon dioxide and nitrogen

• Oxygen and hydrogen

Open Ended

Explain the importance of alveolus structure adaptation in increasing the efficiency of gas exchange in the human body.

Open Ended

Explain how the structure of the alveolus is adapted for efficient gas exchange.

Multiple Choice

Which process allows oxygen and carbon dioxide to move from an area of high concentration to an area of low concentration in the human body?

• Diffusion (Resapan)

• Osmosis

• Active transport

• Filtration

Multiple Select

Which of the following are involved in the process of gas exchange in the alveolus?

• Alveolus

• Red blood cells

• Capillary walls

• White blood cells

Fill in the Blank

Oxygen diffuses from the alveolus into the ___ during gas exchange.

Multiple Choice

What is the function of hemoglobin in red blood cells during gas exchange?

• To bind with oxygen and transport it in the blood

• To digest nutrients

• To produce energy

• To fight infections

Open Ended

Describe the pathway of oxygen from inhaled air to its binding with hemoglobin in red blood cells.
