BIOS 255 Ch 23 The Respiratory System
- Define Respiration
Answer: Respiration is the exchange of gases between the atmosphere, blood, and cells
- The combination of 3 processes is required for respiration to occur
Answer:
Ventilation (breathing) External (pulmonary) respiration Internal (tissue) respiration
- How does the cardiovascular system assist the respiratory system?
Answer: By transporting gases
- Structures of the Respiratory System
- Upper respiratory system
- Lower respiratory system
Answer: Structurally, the components of the respiratory system are divided into 2 parts:
- Functions of the Respiratory System
- Conducting zone
- Respiratory zone
Answer: Functionally, the components of the respiratory system are divided into 2 zones:
6. Upper Respiratory System consists of:
Answer: The nose, pharynx (throat), and associated parts
7. Lower Respiratory System consists of:
Answer: The larynx, trachea, bronchi, and lungs
- Hyaline cartilage
Answer: Hyaline cartilage is found throughout the respiratory tract in order to keep the moist airway open
- Equation for measuring the amount of air that moves in and out of the lungs each minute
(Minute Ventilation) Answer: The product of tidal volume and breathing rate indicates the amount of air that moves into and out of the lungs each minute (minute ventilation, MV = TV × BR). Minute ventilation increases when the body is using more oxygen and producing more carbon dioxide, as occurs in exercising.
10. The interior structures of the external nose have three functions:
Answer: (1) warming, moistening, and filtering incoming air (2) detecting olfactory stimuli (3) modifying speech vibrations as they pass through the large, hollow resonating chambers.
