Chapter 34.3, Problem 1CYL

Summary Introduction

To determine:

The path of food through the human digestive tract, and also to describe the structures and functions of each digestive compartment

Introduction:

Digestive system is responsible for ingesting and digesting the food, absorbing the nutrients and eliminating the waste. The alimentary canal is the passage through which the food passes through our body. This includes mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.

Summary Introduction

To explain:

The absorption of food in the small intestine, and also to determine its structure which facilitates nutrients absorption

Introduction:

The process of disintegration of larger biomolecules into smaller biomolecules in the body is called digestion. It occurs in the mouth, stomach, and small intestine. The major function of intestines is the absorption of nutrients and transferring them into the bloodstreams. The body gets the nutrients for proper functioning of the body.

Summary Introduction

To explain:

The production of feces and their elimination from the body

Introduction:

Food enters the body through the mouth, and after digestion, it is excreted from the body as feces. The circulatory system also interferes with the digestive system to deliver nutrients to the cells of the body.

Summary Introduction

To explain:

The way in which nervous system and hormones regulate digestion of food and food intake

Introduction:

Each organ system is a part of the whole living organism. The specialization of each system requires that it relies on and interacts with other systems so that the organism can function properly and survive. A single system cannot ensure proper function and survival of the organism.
