Which represents the correct functional order (first to last) of the human digestive system?



A) mouth→esophagus→stomach→large intestine→small intestine→rectum


B) mouth→esophagus→stomach→small intestine→large intestine→rectum


C) mouth→esophagus→small intestine→large intestine→stomach→rectum


D) mouth→esophagus→large intestine→small intestine→stomach→rectum


I say B

I agree.

can u do my science helppp

Me either, what do you think it is?

Ms Sue plz?

To determine the correct functional order of the human digestive system, let's examine each option:

Option A: mouth → esophagus → stomach → large intestine → small intestine → rectum
Option B: mouth → esophagus → stomach → small intestine → large intestine → rectum
Option C: mouth → esophagus → small intestine → large intestine → stomach → rectum
Option D: mouth → esophagus → large intestine → small intestine → stomach → rectum

To find the correct answer, we need to know the actual order of the digestive organs in the human body.

The correct order of the human digestive system is as follows:
1. Mouth: This is where the process of digestion begins. Chewing breaks down food into smaller pieces.
2. Esophagus: The esophagus is a muscular tube that connects the mouth to the stomach. It carries food from the mouth to the stomach, using muscle contractions called peristalsis.
3. Stomach: The stomach further breaks down food using acid and enzymes. It also churns the food to aid in digestion.
4. Small Intestine: The small intestine is where most of the absorption of nutrients from digested food takes place. It is divided into three sections: the duodenum, jejunum, and ileum.
5. Large Intestine: The large intestine, also known as the colon, absorbs water and electrolytes from the remaining undigested food, forming feces.
6. Rectum: The rectum is the lower part of the large intestine where feces are stored before they are eliminated from the body.

Comparing the correct order of the digestive system with the given options, we can see that Option B: mouth → esophagus → stomach → small intestine → large intestine → rectum is indeed the correct order.

Therefore, you are correct in choosing Option B as the correct functional order of the human digestive system.
