Respiratory System Flashcards
What is the formula for cellular respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
This equation represents the process where glucose and oxygen are converted into carbon dioxide, water, and energy (ATP).
What are the main reactants in the cellular respiration process?
Glucose and Oxygen
These substances are necessary for cellular respiration to occur.
What are the primary products of cellular respiration?
Carbon Dioxide, Water, and ATP
ATP is the energy currency of the cell, while carbon dioxide and water are byproducts.
Fill in the blank: Cellular respiration converts glucose into _______.
ATP
ATP is produced as a usable form of energy for the cell.
True or False: Oxygen is a product of cellular respiration.
False
Oxygen is a reactant, not a product, in cellular respiration.
What is the role of ATP in cellular respiration?
Energy currency of the cell
ATP provides energy for various cellular processes.
What is the primary function of the respiratory system?
Contributes to homeostasis by providing for the exchange of gases - oxygen and carbon dioxide - between the atmospheric air, blood and tissue cells.
The respiratory system plays a crucial role in maintaining the body’s internal environment by regulating gas levels.
What is external respiration?
The processes by which oxygen from the atmosphere is brought into the circulation
External respiration involves the inhalation of oxygen and the exhalation of carbon dioxide.
What is internal respiration?
The energy producing chemical processes which occur within the cells
Internal respiration refers to the metabolic processes that convert glucose and oxygen into energy, carbon dioxide, and water.

What is the first component of the respiratory system?
Nose
The nose serves as the entry point for air into the respiratory system.
Which part of the respiratory system follows the nose?
Pharynx
The pharynx functions as a pathway for both air and food.
What is the role of the larynx in the respiratory system?
Voice production and protection of the trachea
The larynx contains the vocal cords and helps to prevent food from entering the windpipe.
What structure serves as the windpipe in the respiratory system?
Trachea
The trachea connects the larynx to the bronchi.
How many bronchi are there in the respiratory system?
Two bronchi
The bronchi branch from the trachea into each lung.
What are the smaller branches of the bronchi called?
Bronchioles
Bronchioles lead to the alveoli where gas exchange occurs.
What is the primary function of the lungs in the respiratory system?
Gas exchange
The lungs facilitate the exchange of oxygen and carbon dioxide.
Fill in the blank: The __________ connects the larynx to the bronchi.
Trachea
The trachea is also known as the windpipe.
True or False: The pharynx is only involved in respiration.
False
The pharynx is involved in both respiration and digestion.
What is the main structure that divides into the primary bronchi?
Trachea
The trachea branches into the left and right primary bronchi.
What are the branches of the bronchial tree in order from largest to smallest?
- Primary bronchi
- Secondary bronchi
- Tertiary bronchi
- Bronchioles
- Terminal bronchioles
These branches represent the hierarchical structure of the bronchial tree.
Fill in the blank: The _______ pleura covers the lungs directly.
[Visceral pleura]
Fill in the blank: The _______ pleura lines the thoracic cavity.
[Parietal pleura]
