Question

question 1 1 pts the longest portion of the small intestine is the: duodenum. ileum. jejunum. colon. question 2 1 pts which of the following organs has a mucosa layer composed of stratified squamous epithelium that resists abrasion? esophagus stomach small intestine large intestine question 3 1 pts the proper anatomical order for the divisions of the colon is: descending, transverse, sigmoid, and ascending. ascending, transverse, sigmoid, and descending. sigmoid, ascending, transverse, and descending. ascending, transverse, descending, and sigmoid.

Explanation:

Question 1

The small intestine has three parts: duodenum, jejunum, and ileum. The ileum is the longest among them (about 3 - 6 meters), while duodenum is the shortest, jejunum is middle - length, and colon is part of large intestine.

The esophagus has a mucosa layer with stratified squamous epithelium to resist abrasion from food passage. Stomach, small intestine, and large intestine have different types of epithelium (like simple columnar in stomach and small intestine) not stratified squamous for this function.

The colon's divisions in anatomical order are ascending colon (starts from cecum, goes up), then transverse colon (across the abdomen), then descending colon (goes down), and finally sigmoid colon (curved part before rectum).

Answer:

B. ileum.
