Connecting the Concepts
1. There are several key concepts introduced in this chapter: Structure correlates with function: an animal’s body has a hierarchy of organization with emergent properties at each level: and complex bodies have structural adaptations that increase surface area for exchange. Label the tissue layers shown in this section of the small intestine, and describe how this diagram illustrates these three concepts.
To label: The tissue layers as shown in the section of small intestine. Also to describe the concept that ‘the structure correlates with functions’; ‘an animal’s body has a hierarchy of organization with emergent properties at each level’; and ‘complex bodies have structural adaptations that increase surface area for exchange’ in the diagram.
Introduction: The structure of each specialized cell type fits to their functions. A tissue derives its function by the cells that make it up. For example,the columnar epethelial cells.
Connective tissues have fibres and cells that provide support and connection to the tissue. Therefore, the connection of cell to tissue to the organ is visible in the given diagram.
There are many projections that line the surface of the small intestine for the absorption of the nutrients. The villi increases the surface area of the small intetine for absorption of nutrients.
Answer to Problem 1CC
Pictorial representation: A labeled diagram showing different tissue layers in a section of small intestine is presented in the Fig.1.
Fig.1: Different section of small intestine.
Explanation of Solution
(a)
Correct answer: Epithelial tissue.
Explanation: In the small intestine, epithelial tissue covers the outside of the villi. Hence the correct answer is epithelial tissue.
(b)
Correct answer: Connective tissue.
Explanation: Connective tissue attaches and provides support to the organs. Hence the correct answer is connective tissue
(c)
Correct answer: Smooth muscle tissue.
Explanation: Small intestine requires strength to push the digested product down its length, and this is provided by smooth muscle tissue. Hence the correct answer is smooth muscle tissue.
(d)
Correct answer: Connective tissue.
Explanation: Connective tissue attaches and provides support to the organs. Hence the correct answer is connective tissue.
(e)
Correct answer: Epithelial tissue.
Explanation: It attaches to the smooth muscle tissue and provide strength to the small intestine. Hence the correct answer is epithelial tissue.
