Cat Respiratory System Concepts

The video tutorial explores the cat respiratory system, detailing the anatomy and function of the lungs, trachea, larynx, and epiglottis. It explains the role of the diaphragm in breathing and the importance of pleural membranes in maintaining lung inflation. The tutorial also highlights the detrimental effects of smoking on lung elasticity and function, using a pig lung as a demonstration.

What is the primary function of the pharynx in the cat respiratory system?

• Conducting air to the lungs

• Conducting food to the trachea

• Conducting food to the stomach

• Conducting air to the larynx and food to the esophagus

What is the role of the thyroid cartilage in the cat's respiratory system?

• It is involved in voice production

• It protects the trachea

• It is part of the nasal cavity

• It conducts air to the lungs

What is the function of the epiglottis?

• To produce sound

• To prevent food from entering the larynx during swallowing

• To conduct air to the lungs

• To keep the trachea open

What type of cartilage keeps the trachea open during pressure changes?

• Elastic cartilage

• Hyaline cartilage

• Fibrocartilage

• Thyroid cartilage

What is the function of the trachealis muscle?

• To produce sound

• To conduct air to the lungs

• To allow flexibility for food passage in the esophagus

• To keep the trachea open

How many lobes does the right lung of a cat have?

• Four

• Three

• Five

• Two

What is the primary function of the respiratory diaphragm?

• To conduct air to the lungs

• To facilitate breathing by changing intrapulmonary pressure

• To produce sound

• To protect the lungs

What is the role of the pleural membranes?

• To protect the trachea

• To reduce friction and keep the lungs inflated

• To produce sound

• To conduct air to the lungs

What happens to intrapulmonary pressure when the diaphragm contracts?

• It increases

• It decreases

• It remains the same

• It fluctuates

What is the primary reason for lung collapse in the event of a broken rib?

• Loss of intrapleural pressure

• Loss of intrapulmonary pressure

• Loss of tracheal cartilage

• Loss of elasticity in the bronchial tree
