Liver recieves nutrients from the digestive tract using the hepatic portal vein system, which are further absorbed and supplied to the body.

Small intestines consist of micro hair-like structures, the villi and microvilli that aid in nutrients absorption by increasing the surface area.

Stomach is the only digestive organs with multiple layers of muscles that breaks down large pieces of food into smaller chunks.

Pancreas serves the function of secreting different enzymes (amylases, lactase, galactosidase) that can digest carbohydrates, lipids, and proteins depending on the source of food you have eaten at that given moment.

Large intestines houses some good bacteria, our normal micro flora that further breakdown and digest food that might have passed. These freindly bacteria also act as source of vitamin B and K.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
