| + | The nasal cavity in the '''sheep''' is highly vascularised, with any damage to the epithelium resulting in severe [[Haemorrhage - Pathology|haemorrhage]]. '''Cattle''' have a smaller nasal cavity compared to the horse. There are many variations to the entire [[Avian Respiration - Anatomy & Physiology|'''avian''' respiratory tract]]. The [[Respiration in Non-Homeotherms - Anatomy & Physiology|respiratory systems of non-homeotherms]] are also very different to that of mammals. |
