What else can I help you with?
When you swallow a peanut the peanut first comes in contact with pancreatic juice?
digestive mucosa
Which structure in the digestive system comes to direct contact with the circulatory system for transfer of nutrients into the blood?
The small intestine is the answer your looking for.
An exchange surface is in direct contact with the external environment in the?
An exchange surface is in direct contact with the external environment in the respiratory and digestive systems. In the respiratory system, the alveoli in the lungs act as exchange surfaces for oxygen and carbon dioxide. In the digestive system, the lining of the small intestine serves as an exchange surface for the absorption of nutrients.
What is the order of food passing through your body?
Food moves the digestive system through the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. Solid food waste is expelled through the anus, at the end of the digestive tract.
What is a typhlosole?
A typhlosole is a fold in the intestine of certain animals, such as earthworms, that increases the surface area available for nutrient absorption. It helps in the digestion process by increasing the contact between food and digestive enzymes, allowing for more efficient absorption of nutrients.
Which organs of the digestive system come in contact with food?
mucosa
How is self-digestion of the stomach and small intestine prevented?
Self-digestion of the stomach and small intestine is prevented by the mucus lining that protects these organs from the acidic and enzymatic activity of the digestive juices. Additionally, the cells of the stomach and small intestine have tight junctions that prevent digestive enzymes from leaking out and causing harm. The presence of bicarbonate in the mucus also helps to neutralize any excess acid that may come into contact with the lining.
Where cell has the largest surface area?
Cells with the largest surface area are typically found in specialized structures like the small intestine. The cells lining the small intestine have microvilli, which greatly increase the surface area for absorption of nutrients. These cells are specifically adapted to maximize their contact with nutrients in the digestive system.
How do enzymes produced in the pancreas come in contact with food since the food does not pass through the pancreas?
Enzymes produced in the pancreas are secreted into the small intestine through the pancreatic duct. When food enters the small intestine from the stomach, these enzymes mix with the food as it is digested. This allows the enzymes to break down carbohydrates, proteins, and fats, facilitating nutrient absorption. Thus, even though food doesn't pass through the pancreas, the enzymes reach it effectively in the small intestine.
What is the site of contact digestion?
the brush border of the small intestine
Define segmentation as in digestive system?
Segmentation in the digestive tract mixes food with digestive juices and increases the rate of absorption by repeatedly moving different parts of the food mass over the intestinal wall.
