Transport of Carbon IV oxide in the respiring muscles

 

Explain how carbon (IV) oxide produced by respiring muscles of the biceps reaches the alveolar cavities in mammalia lungs. (20marks)



Suggested resposponses


Carbon (iv) oxide from the respiring cells of the biceps muscles diffuse in to the blood; within the venule bed of capillaries; where it forms weak carbonic acid; in the plasm; and carbominohaemoglobin in the red blood cells; from here blood moves into a bronchial vein; which joins the subclavian...
