Describe the function of the digestive system, including tissues specialties, and differentiate between organs of the alimentary canal and accessory digestive organs.

First of all the main function of the digestive system is to break down the foods we eat and release the nutrients from the nourishment as the esophagus warms and moistens the nutrients, which then helps them absorb into the body.

There are 2 different parts of the digestive system.

The alimentary canal is known as the GI tract and it's purpose is to absorb the nutrients.

The accessory digestive organ helps in the breakdown of food in the digestive system.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
