• Eteral respiratio - Gas exchange between lungs
blood
• Trasport of respirator gases
• Iteral respiratio – Gas exchange between blood
tissues
Regulation of blood pH

Document Summary
Number of breaths taken per minute total amount of air moved into and out of the respiratory system each minute (tidal volume x respiratory rate) e. g. 5(cid:1004)(cid:1004) (cid:373)l x (cid:1005)(cid:1006) breaths per (cid:373)i(cid:374)ute = 6000 ml per minute space formed by nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and terminal bronchioles. volume of air available for gas exchange per minute. Respiration: ve(cid:374)tilatio(cid:374) movement of air in and out of lungs, e(cid:454)ter(cid:374)al respiratio(cid:374) - gas exchange between lungs blood, tra(cid:374)sport of respirator(cid:455) gases, i(cid:374)ter(cid:374)al respiratio(cid:374) gas exchange between blood tissues. Conducting zone- respiratory passages from nose to bronchi in lungs, humidifies air. Respiratory zone (in lungs)- exchange of air between lungs and blood. Stratified squamous epithelium, sweat and sebaceous glands and hair follicles. Septum separates nasal cavity into left and right parts. Epithelium of concha (and most of nasal cavity) is pseudostratified ciliated columnar epithelium. Choana - narrowing at posterior aspect of nasal cavity.
