Most animals consume large and complex foods. Large food particles are broken down into smaller monomers in such a form that can be circulated to every cell throughout the body. These functions are carried out by a set of specialized structure present in an organism called as digestive system . Most of the organism undergoes extracellular digestion. Four tasks are mainly carried out by the digestive system: ingestion, digestion, absorption, and elimination.

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.

Summary Introduction

Introduction: Most animals consume large and complex foods. Large food particles are broken down into smaller monomers in such a form that can be circulated to every cell throughout the body. These functions are carried out by a set of specialized structure present in an organism called as digestive system. Most of the organism undergoes extracellular digestion. Four tasks are mainly carried out by the digestive system: ingestion, digestion, absorption, and elimination.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: A digestive system functions in order to secrete enzymes, absorb compounds, and eliminate wastes.

Hence, the correct answer is option d.

Explanation of Solution

Reason for correct answer: Digestion of food material starts at the point of the food consumption itself. Varied enzymes are released to break down the food to simpler form. The larger and complex macromolecules are converted to simpler absorbable form. Then, the nutrients are absorbed to respective structures and circulated throughout the body of the organism. At the end of the digestive process, the undigested and unabsorbed materials are expelled out of the organism.

Option d. is given as “all of the above”. This is correct because the digestive system performs all the given functions. It secretes enzymes, absorbs compounds, and also helps in excreting toxic compounds out of the body.

Hence, the correct answer is option d.

Reasons for incorrect answer:

Option a. is given as “secreting enzymes”. Digestive system secretes a series of enzymes called as digestive enzymes that help to break down the complex macromolecules into simpler monomers. But this is incorrect because secreting enzyme is only one of the functions performed by the digestive system. Hence, the correct answer is option a.

Option b. is given as “absorbing compounds”. A digestive system functions as absorbing compounds. Digestion of complex molecules gives small monomers. While passing through the walls of the digestive organ, it gets absorbed to the internal environment of the organism. But this is incorrect because they also perform other functions like secreting enzyme and eliminating waste. Hence, option b. is incorrect.

Option c. is given as “eliminating wastes”. The waste materials that are not digested and absorbed are eliminated by the body. This is incorrect as the digestive system is also involved in other functions. After only digestion and absorption, the elimination step can be carried out. Hence, option c. is incorrect.

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

Conclusion

A digestive system functions in secreting different enzymes to digest the food, absorption of nutrient compounds into the cells, and eliminating wastes out of the body.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
