Questions: Although stratified columnar epithelial tissue is considered rare throughout the human body, it may be found in the: stomach small intestine pharynx small intestine larynx anal canal trachea larynx.

The answer is the third one: larynx & anal canal.

Explanation for each option:

1. Stomach & small intestine: Stratified columnar epithelial tissue is not typically found in the stomach or small intestine. These areas are more commonly lined with simple columnar epithelium.
2. Pharynx & small intestine: Similar to the first option, the small intestine is lined with simple columnar epithelium, and the pharynx is usually lined with stratified squamous epithelium.
3. Larynx & anal canal: Stratified columnar epithelial tissue can be found in parts of the larynx and the anal canal, making this the correct answer.
4. Trachea & larynx: The trachea is lined with pseudostratified ciliated columnar epithelium, not stratified columnar epithelium.

Summary: Stratified columnar epithelial tissue is rare but can be found in the larynx and anal canal.
