Study Notes
Respiration
- Process of converting food into energy
- Provides energy for our bodies
- Used for:
- Thinking
- Moving
- Breathing
- Heartbeat
- Talking
Gas Exchange Surfaces
- Large Surface Area: Allows for maximum contact between gases and the respiratory system
- Good Transport System: Efficiently transports gases throughout the system
- Specialized Cells (goblet cells): Produce mucus to trap foreign particles
- Alveoli: Small air sacs where gas exchange occurs
- Larynx: Structure known as the voice box where vocal cords are located
- Nicotine: Addictive substance found in tobacco that enters the body during smoking.
- Chronic Obstructive Pulmonary Disease (COPD): Disorder that blocks the airway passages of the respiratory system
Respiration: True or False
- Anaerobic respiration does not use oxygen, it uses glucose to produce energy, lactic acid, and water.
- Plants and yeasts produce alcohol during anaerobic respiration, not aerobic respiration.
- The pharynx is a part of both the digestive and respiratory system.
- The nasal cavity contains mucus to trap foreign materials from entering the lungs.
- The epiglottis is located at the top of the trachea and prevents food from entering the airways.
- The trachea branches into two bronchi that enter the lungs.
- Cilia are hair-like structures that move mucus out of the respiratory tract.
- Carbon dioxide is not poisonous, it is a byproduct of respiration.
- During inspiration, there is more oxygen in the lungs than during expiration.
- During exhalation, there is more carbon dioxide in the lungs than during inhalation.
Respiration
- Respiration is the process that converts the energy stored in food into a form that our bodies can use.
- This energy is used for:
- Thinking
- Moving
- Breathing
- Heartbeat
- Talking
Gas Exchange Surfaces
- Gas exchange surfaces have special characteristics:
- Large surface area to allow for efficient gas exchange.
- Good transport system to move gases in and out of the surface.
- Specialized cells, called goblet cells, that produce mucus.
Respiratory System: Structures and Functions
- Alveoli: Small air sacs where gas exchange occurs.
- Larynx: Structure also known as the voice box where vocal cords are located.
- Nicotine: Addictive substance in tobacco that enters the body when smoking.
- COPD (Chronic Obstructive Pulmonary Disease): A term used for disorders that block the airway passages of the respiratory system.
Respiration: Anaerobic and Aerobic
- Anaerobic respiration: Doesn't involve oxygen and only produces a small amount of energy.
- Aerobic respiration: Requires oxygen and produces much more energy.
- Plants and yeasts produce alcohol during anaerobic respiration.
Respiratory System: Structures and Functions
- Pharynx: Part of both the digestive and respiratory systems.
- Nasal Cavity: Contains mucus to trap foreign materials entering the lungs.
- Epiglottis: A flap of tissue that covers the trachea during swallowing, preventing food from entering the lungs.
- Trachea: Branches into two bronchus that enter the lungs.
- Cilia: Hair-like structures that move mucus out of the respiratory tract.
Gas Exchange: Inspiration and Expiration
- Inspiration: Taking air into the lungs, bringing more oxygen.
- Expiration: Exhaling air out of the lungs, removing carbon dioxide.
- Carbon dioxide is not a poisonous gas, but rather a byproduct of respiration.
- Oxygen is essential for life.
