The diagram below represents an organ in a bony fish
​(a) Name the organ.
(b) Describe how air in water reach the capillaries inside structure L.
ANSWERS
a) Gill;
b) Fish mouth opens lowering pressure in buccal cavity and water rushes in; mouth closes increasing pressure that forces water into the gill cavity/opercular cavity; O2 rich water flows over the gills in a counter current direction to capillary blood flow; causing O2 to diffuse into the gill capillaries;
