What is the term for the process of regulating body temperature?
Thermoregulation
Where are the vocal cords located?
In the larynx
What is the function of panting in thermoregulation?
To lose heat
The respiratory system is responsible for removing oxygen from the tissues.
False
The vocal cords are located in the nasal cavity.
False
Panting is a mechanism used to retain heat in thermoregulation.
False
The olfactory nerve is responsible for the sense of smell.
True
The respiratory system is only responsible for providing oxygen to the tissues.
False
Match the following respiratory functions with their descriptions:
Respiratory function = To provide oxygen O2 to, and remove carbon dioxide CO2 from the tissues Vocalisation = Via vocal cords in the larynx Thermoregulation = Panting to lose heat, counter-current heat exchange to retain heat Olfaction = Smell - olfactory nerve has a close association with the nasal cavity
Match the following components with their locations:
Vocal cords = In the larynx Olfactory nerve = In the nasal cavity Vocalisation = In the lungs Panting = In thermoregulation process
Match the following processes with their purposes:
Panting = To lose heat in thermoregulation Counter-current heat exchange = To retain heat in thermoregulation Olfaction = To provide oxygen to the tissues Vocalisation = To produce sound
Match the following senses with their associated organs:
Smell = Nasal cavity Hearing = Ear Sight = Eye Taste = Tongue
Match the following thermoregulation mechanisms with their effects:
Panting = Lose heat Counter-current heat exchange = Retain heat Shivering = Gain heat Sweating = Lose heat
What is the primary function of the respiratory system?
To provide oxygen to the tissues and remove carbon dioxide
Where are the vocal cords located?
In the larynx
What is the role of panting in thermoregulation?
To lose heat
What is the role of the olfactory nerve in the nasal cavity?
To facilitate the sense of smell
What is another function of the respiratory system?
To facilitate thermoregulation
What is the main difference between the upper and lower respiratory tracts?
The upper respiratory tract includes the nasal cavity, sinuses, and oral cavity, while the lower respiratory tract includes the trachea, bronchi, and lungs.
Which of the following is NOT a part of the upper respiratory tract?
Trachea
What is the function of the pharynx in the upper respiratory tract?
Swallowing and filtering air
Which of the following is a part of the lower respiratory tract?
Bronchioles
Why is the trachea considered part of the lower respiratory tract in this course?
Because it is not a part of the upper respiratory tract
What is the main difference between the upper and lower respiratory tracts?
The upper respiratory tract is responsible for filtering and warming the air, while the lower respiratory tract is responsible for gas exchange.
Which of the following is a part of the lower respiratory tract?
Trachea
What is the function of the pharynx in the upper respiratory tract?
To swallow food and air
Why is the trachea considered part of the lower respiratory tract in this course?
Because it is not part of the textbook's definition of the upper respiratory tract
Which of the following is NOT a part of the upper respiratory tract?
Lungs
Study Notes
Respiratory System Terminology
- Pulmonary refers to the lungs or relating to the lungs
- Bronchi (plural) are the airways that branch off from the trachea and lead to the lungs, while bronchus (singular) is a single airway
- Alveoli (plural) are the tiny sacs within the lungs where gas exchange occurs, and alveolus (singular) is a single sac
- Lumen is the inner space within a tubular organ, such as a blood vessel or airway, and can also refer to an opening
- Hilus or hilum is the indentation in an organ, such as the lung, kidney, or spleen, where blood vessels, ducts, and other structures enter or leave the organ
- Cilia are small hair-like projections from the cell membrane that help move particles or substances along the surface of the cell
