Up close: Gills. The clam gills play an interesting role in the clam's survival. The gills have two functions in two separate systems of the clam. For the digestive system, the gills aide in digestion through separating silt from the nutrition and aids in the respiratory system through providing oxygen to the clam.
Humans use their lungs to inhale oxygen from the air. But worms, fish, crabs and other underwater animals use gills to get oxygen from the water. As water moves across an animalâs gills, oxygen is removed and passed into the blood. Gills work better when there is more oxygen in the surrounding water.
