Answer 1

Question

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

Expert Solution & Answer

Answer to Problem 1CA

Correct answer: d. all of the above

Explanation of Solution

Reason for the correct answer:

Option d. is given as “all of the above”.

The digestion process can be defined as the chemical and mechanical breakdown of food, and in addition, the absorption of resulting nutrients. Mechanical digestion refers to the breakdown of large food pieces into smaller pieces without changing their chemical composition. Chemical digestion refers to the breakdown of large nutrients into simpler forms of chemicals. These processes are carried out by the organs of the digestive system.

Hence, the correct answer is option d.

Reasons for incorrect answers:

Option a. is given as “mechanical breakdown of foods”.

One of the functions of the digestive system includes the mechanical breakdown of foods. This system also carries out other functions such as the chemical breakdown of foods and breaking of large food particles into smaller ones. Therefore, option a. is incorrect.

Option b. is given as “breaking large pieces of food into smaller ones without altering”. One of the functions of the digestive system includes the breaking of large food particles into smaller ones. This system also carries out other functions such as the mechanical and chemical breakdown of foods. Therefore, option b. is incorrect.

Option c. is given as “chemical breakdown of foods”.

One of the functions of the digestive system includes the chemical breakdown of foods. This system also carries out other functions such as the mechanical breakdown of foods and breaking of large food particles into smaller ones. Therefore, option c. is incorrect.

Hence, options a., b., and c. are incorrect.

Conclusion

The chemical and mechanical breakdown of foods and breakdown of large food particles into small particles are the functions of the digestive system.
