- 1-e, 2-d, 3-c, 4-b, 5-a — Correct Answer
- 1-c, 2-d, 3-e, 4-b, 5-a
- 1-e, 2-c, 3-d, 4-b, 5-a
- 1-d, 2-e, 3-c, 4-b, 5-a
Explanation:
Correct Answer: 1-e, 2-d, 3-c, 4-b, 5-a
- 1-e: Costo-abdominal Respiration → Horse, Mule, Donkey — Equines use both thoracic (costal) and abdominal muscles for breathing, hence costo-abdominal respiration.
- 2-d: Costal Respiration → Cat, Dog — Carnivores (cat, dog) rely primarily on thoracic (costal/rib) muscles for breathing.
- 3-c: Abdominal Respiration → Ruminants — Cattle, sheep, and goats predominantly use abdominal (diaphragmatic) muscles for respiration, giving an abdominal respiratory pattern.
- 4-b: Inspiration → Dorsal Respiratory Center (DRG) — The Dorsal Respiratory Group in the medulla is the primary generator of the inspiratory drive, activating diaphragm and external intercostals.
- 5-a: Forced Expiration → Ventral Respiratory Center (VRG) — The Ventral Respiratory Group is activated during forced/active expiration, recruiting internal intercostals and abdominal muscles. During quiet breathing, expiration is passive (no VRG needed).
