Multiple Choice

Why is an artery classified as an organ in the human body?

Because it is composed of multiple tissue types working together to perform a specific function.

Because it only contains a single layer of epithelial tissue.

Because it transports oxygen directly into cells.

Because it is the largest blood vessel in the body.

Verified step by step guidance

Step 1: Begin by understanding the definition of an organ in the human body. An organ is a structure composed of two or more tissue types working together to perform specific functions.

Step 2: Analyze the structure of an artery. Arteries are composed of multiple tissue types, including epithelial tissue (endothelium), smooth muscle tissue, and connective tissue, which work together to transport blood throughout the body.

Step 3: Consider the function of an artery. Its primary role is to carry oxygenated blood away from the heart to various tissues and organs, which is a specific and vital function in the circulatory system.

Step 4: Evaluate the incorrect options. For example, arteries do not transport oxygen directly into cells (this is the role of capillaries), and they are not classified as organs based on their size or being the largest blood vessel.

Step 5: Conclude that the correct answer is: 'Because it is composed of multiple tissue types working together to perform a specific function,' as this aligns with the definition of an organ and the structure and function of arteries.
