Respiratory System

What are the main organs of the respiratory system?

• Kidneys, liver, stomach

• Lungs, trachea, bronchi, diaphragm, bronchioles

• Brain, spinal cord, pancreas

• Heart, spleen, intestines

Explain the process of gas exchange in the lungs.

• Gas exchange in the lungs involves the release of oxygen from the bloodstream into the air.

• Gas exchange in the lungs involves the transfer of nitrogen from the air into the bloodstream.

• Gas exchange in the lungs involves the transfer of oxygen from the air into the bloodstream and the release of carbon dioxide from the bloodstream into the air.

• Gas exchange in the lungs involves the transfer of carbon dioxide from the air into the bloodstream.

Why is it important to have healthy lungs?

• Healthy lungs are important for brain function.

• Healthy lungs are important for digestion.

• Healthy lungs are important for proper breathing, oxygen exchange, and overall respiratory function.

• Healthy lungs are important for singing abilities.

What is the function of alveoli in the respiratory system?

• Gas exchange

• Food digestion

• Oxygen production

• Blood circulation

What is the role of bronchi in the respiratory system?

• Bronchi aid in regulating blood flow in the respiratory system

• Bronchi help in producing mucus in the lungs

• Bronchi are responsible for filtering oxygen from the air

• Bronchi play a crucial role in conducting air into the lungs and facilitating gas exchange.

Describe the function of the trachea in the respiratory system.

• The trachea plays a role in regulating blood flow in the respiratory system.

• The trachea is responsible for producing mucus in the respiratory system.

• The trachea functions as a storage organ for excess air in the respiratory system.

• The trachea functions as the passage for air to move between the larynx and the bronchi, while also assisting in filtering and cleaning the air.

Why do our bodies need oxygen?

• Our bodies need oxygen for digestion.

• Our bodies need oxygen for muscle growth.

• Our bodies need oxygen for photosynthesis.

• Our bodies need oxygen for cellular respiration.

What happens to the carbon dioxide we exhale?

• It is released into the atmosphere.

• It is absorbed by plants

• It turns into oxygen

• It disappears into thin air

How does oxygen reach the bloodstream in the lungs?

• Oxygen is carried by white blood cells to the bloodstream

• Oxygen is transported through the lymphatic system

• Oxygen is directly absorbed through the skin

• Oxygen diffuses across the alveolar membrane into the capillaries surrounding the alveoli and binds to hemoglobin in red blood cells for transport.

What is the primary function of the respiratory system?

• Digest food

• Transport nutrients

• Regulate body temperature

• Facilitate gas exchange
