They digest and store food
The reproductive gland in a clam are present at the interior system. This gland is used for reproduction by the clam.
Food enters the clam through its mouth and moves to the stomach, where digestion begins. Next, the nutrients are absorbed in the digestive gland and waste is excreted through the anus. The process is facilitated by cilia and muscular contractions within the digestive system.
the clam uses the digestive glands for chemical digestion needed for some of their food
The heart is nestled between the digestive gland, and the 'muscle' (two parts, fast mucle, closes shell quickly, and the slow muscle, which holds the shell together for long periods of time.)
Yes, after digging them, place them in a bucket of water and wait for nature to take it's course. Then cook them according to your recipe. Good way to rinse the sand out of them while you're at it.

It forces its stomach out, and sticks it inside of the clams shell. Then with the clam inside of the stomach, the starfish puts its stomach back on its inside. A sea star opens up a clam by attaching its hundreds of tube feet to the external surface of the shell with suction. Then, it pulls. It might have to pull for hours, or days, until the adductor muscle holding the shell firmly closed is finally weakened enough that the shell opens. Then the star fish can force its stomach in and digest the soft insides of the clam.

Some stoves are referred to as clam shells because they resemble the form and function of the shells of a clam. They are compact with hinge joining two halves.
Because they don't have teeth to crush food, they swallow the food whole then let the digestive juices break it down. Starfish don't exactly swallow either. They extrude their stomachs out over their prey. This works well if you feed on clams - you put your stomach inside the clam's shell; little chance of getting a clam out of its shell. This method of feeding suffers a good deal of leakage (as you can well imagine) so the starfish is required to produce lots of digestive juices to make up for the losses.
