Alveoli are part of the reparation system found in the lungs. They are covered in capillaries. In Alveoli, oxygen diffuses from the air into the blood vessels surrounding the alveoli and carbon dioxide from the body diffuses from blood into the alveoli’s air spaces. Alveoli clump together and form sacs.
Explanation:
<u>The stomach </u>
Digestion describes the intake, chemical and physical breakdown, absorption of nutrients and excretion of food with the use of enzymes. The stomach secretes the enzyme, gastric lipase to digest fats.
Further Explanation:
Food is chemically and mechanically broken down into smaller particles. In the stomach the enzyme gastric lipase acts on lipids, breaking them up into their components. Phospholipids, bile acids, bilirubin, and cholesterol are combined into bile in the liver, which when secreted into the duodenum of the small intestine; this comes from its storage site, the gall bladder, and functions as an emulsifier or as a detergent.
These hold the fats and water together and increase the surface area of lipids, which can be further digested by enzymes so the nutrients are further broken down for absorption into the bloodstream.

Answer: Backdating the time required for food found in the stomach of the deceased to digest. Since digestion can't continue after death.
Explanation: The time taken for food to get digested can be employed to depicts time of death. This process involves understanding the period of time that usually takes the food found in the gastric of the deceased to calculate the time of death.
Different foods has varying time of digestion, so therefore, the gastric content is a good indicator to determine time of death by the doctor who is carrying out autopsy, since digestion does not continue after death.
However, it is established by scientist that food takes up to 4-6hours in the stomach depending on the size and type of food. Hence, if the status of the food found in the deceased stomach is noted accordingly and the time taken requires for digestion is also noted، the doctor can deduce the time of death accordingly from this two points.
if you are aking if that is true then yes but there are also secondary, primary consumers... decomposers... detritivores
