Respiratory Sytem Flashcards
Name the pouch like structures in the lungs
Alveoli
State two functions of the lungs
Intake of oxygen
Expelling carbon dioxide
What is the main airway into an animals chest called?
The trachea
State three ways by which an animal can prevent dust entering the lungs
Mucous
Coughing/choking
Cilia
Define the process of respiration
Respiration is the burning of energy sources
What is the normal respiratory rate of the cat?
20-30bpm
What is the normal respiratory rate of the dog?
10-30bpm
List the components of the respiratory system.
Nose Nasal cavity Pharynx Epiglottis Larynx Trachea Bronchi Bronchioles Alveoli
What is the name of the most prevalent gas present in the air?
Nitrogen
What is the equation for respiration?
CHO+O2= CO2 + H2O
Carbohydrate food+oxygen = energy+carbon dioxide+water
What are the two by products of respiration?
Carbon dioxide and water
CO2+H2O
What are the chambers within the nasal cavities function?
- Take in air/oxygen
- smell
What is the epiglottis function?
Piece of elastic cartilage
Prevents food from entering the air passages
Which structures allow the trachea to remain open?
C-shaped rings of cartilage
What is the position of the trachea in relation to the oesophagus?
Oesophagus is dorsal to the trachea
Which body cavity is the lugs found in?
Thoracic cavity
What is the larynx?
The voice box
Consists of two flaps which allows animal to communicate
Controlled by muscles and ligaments
What is the function of the trachea?
Allow passage of air down animals chest and into bronchi
What do the bronchi tubes branch off into?
Bronchioles
What do bronchioles have at the end of them?
Alveoli (pouched like air sacs)
What is the function of alveoli?
Thin walled and contain capillaries for gas exchange
What helps to trap dust in the nasal cavity?
Mucous lining and cilia
What are all air passages covered with?
Mucous secretion and tiny hairs called cilia
What is the function of cilia?
Sweep the mucous containing dust up into animals throat.
