What are goblet cells? What do they produce? What role does mucus play in the respiratory system?
- Goblet cells contain tiny hairs known as cilia. - The goblet cells produce mucus. - The cilia in the goblet cells and the mucus work together to trap and remove foreign particles from the airways, a process known as mucociliary transport.
- What is respiration? - What occurs during this process?
- Respiration is the cycle of inspiration and exhalation completed by the lungs during which the exchange of oxygen and carbon dioxide occurs. - The respiratory process has two components. The first component takes place when the body brings oxygen into the lungs via inhalation and the transports it to the bloodstream for distribution throughout the body tissues. During respiration, the body also completes the second component of gas exchange, the removal of carbon dioxide from the body, which is the exhaled as a waste product.
What are the 2 divisions of the respiratory system?
- The upper respiratory tract - The lower respiratory tract
productive vs nonproductive (dry) cough Which one will produce?
A productive cough will result in the expulsion of mucus from the lungs or lower respiratory tract while a nonproductive (dry) cough will not produce secretions.
The lower respiratory system is made up of what structures?
Lower respiratory tract: - bronchi - alveoli - lungs
What role does the diaphragm (structure the separates the thoracic and abdominal cavities) play in respiration?
The primary role of the diaphragm as it pertains to the respiratory system to assist the lungs in moving air.
What is the primary role of the respiratory system in the body?
The respiratory system is primarily responsible for gas exchange within the body, knows as respiration.
The upper respiratory system contains what structures?
Upper respiratory tract: - nose - nares - nasal passages - sinuses - pharynx - larynx - trachea
a) What occurs during inhalation?
When the diaphragm contracts, its cover shape flattens, and the thoracic cavity expands, helping the lungs pull in oxygen.
b) What occurs during exhalation?
When the diaphragm relaxes it returns to a convex shape, decreasing the volume of the thoracic cavity and helping the lungs expel carbon dioxide.
