When considering an internal organ like the heart or liver, based on what you know about epithelial tissue, do you think that most of the tissue that makes up that organ would be epithelial tissue or some other kind of tissue?

• A. Mostly epithelial tissue.
• B. Mostly some other kind of tissue.

Answer: (B)

Verified step by step guidance

1. Understand the role of epithelial tissue: Epithelial tissue primarily serves as a protective layer, covering surfaces and lining cavities of organs. It is involved in absorption, secretion, and sensation.
2. Consider the structure of internal organs: Internal organs like the heart and liver have complex structures that require various types of tissues to perform their functions.
3. Identify the primary tissue types in the heart: The heart is mainly composed of cardiac muscle tissue, which is responsible for its contractile function, along with connective tissue, nervous tissue, and a small amount of epithelial tissue lining the heart chambers.
4. Identify the primary tissue types in the liver: The liver is primarily made up of hepatocytes, which are specialized liver cells, along with connective tissue and a small amount of epithelial tissue lining the bile ducts.
5. Conclude the tissue composition: While epithelial tissue is present in these organs, the majority of the tissue in both the heart and liver is composed of other types of tissues, such as muscle tissue in the heart and specialized liver cells in the liver.
