Human Respiratory System

Name the parts of human respiratory system in the diagram !

What happen to the lime water at the end of the experiment on the diagram

• Lime water at inhale air is more cloudy

• Lime water at exhale air is more cloudy

Y shape tube in the model represent

• Trachea

• Bronchus

• Rib cage

• Diaphragm

The air sacs that are covered with capillaries where gas exchange takes place

• bronchi
• lungs
• oxygen
• alveoli

What is the main function of the respiratory system?

• to provide oxygen and remove carbon dioxide from the body
• to bring oxygen to the body
• to break down food and absorb nutrients
• to remove oxygen from the body and deliver carbon dioxide

Experiment in the diagram is to

• To determine the percentage of oxygen in exhale air

• To determine the percentage of oxygen in inhale air

• To determine the concentration of oxygen in exhale air

• To determine the concentration of carbon dioxide in exhale air

When you exercise, your heart beats faster to...

• spread oxygen throughout your body more quickly.
• make you feel excited.
• let you know you're working hard.
• inflate your lungs

The smallest passageway taking air to the alveoli

• Bronchi

• Bronchus

• Bronchioles

• Alveioli

Clusters of tiny air sacs that allow the exchange of oxygen and carbon dioxide

• Pharynx
• Diaphragm
• Alveoli
• Lungs

This system transports essentials and removes wastes to and from the cells of the body.

• circulatory
• respiratory
• skeletal
• integumentary
