A Big Mac contains a bun, hambuger, pickles, lettuce, tomatos, and a special sauce (mayo) which part if a big mac is chemically broken down in each digestive system organ?
Mouth-
Stomach-
Small Intestines-
Large Intestines-
HELP
EMILEIGH =D
THIS IS HOW YOU EAT
yum mayo my favorite
To determine which parts of a Big Mac are chemically broken down in each digestive system organ, we need to understand the process of digestion. Here's a breakdown of the digestion process for the components of a Big Mac:
1. Mouth: In the mouth, the Big Mac's bun, hamburger, pickles, lettuce, tomatoes, and special sauce (mayo) are mechanically broken down through chewing and mixing with saliva. However, there is no significant chemical breakdown of these components in the mouth.
2. Stomach: When the partially broken down food enters the stomach, the pH becomes acidic due to the stomach's gastric glands producing hydrochloric acid. This acidic environment helps break down the proteins in the hamburger patty. The special sauce, pickles, lettuce, and tomatoes also undergo some breakdown by the stomach acid.
3. Small Intestines: After leaving the stomach, the partially digested food enters the small intestine. Here, the secretions from the pancreas and gallbladder help further break down the components of the Big Mac. The bun, lettuce, tomatoes, and special sauce are broken down further by digestive enzymes released from the pancreas, primarily amylase for breaking down carbohydrates. The gallbladder secretes bile, which assists in the breakdown of fats in the special sauce.
4. Large Intestines: By the time the partially digested food reaches the large intestine (colon), most of the breakdown and absorption of nutrients have already occurred. The colon's main role is to absorb water and electrolytes from the remaining undigested food, resulting in the formation of feces. Therefore, the large intestine does not play a significant role in the breakdown of the components of the Big Mac.
So, to summarize:
- Mouth: Mechanical breakdown, no significant chemical breakdown
- Stomach: Acidic environment breaks down proteins, some breakdown of special sauce, pickles, lettuce, and tomatoes
- Small Intestines: Further breakdown of bun, lettuce, tomatoes, and special sauce by digestive enzymes and bile
- Large Intestines: Minimal involvement in breakdown, primarily absorbs water and electrolytes
I hope this helps clarify the process of digestion for the components of a Big Mac!
