How does the length of the small intestine relate to its job of absorbing nutrients from food frog?
Because nutrients in food are absorbed into the body through diffusion or active transport, the nutrients must come into contact with the walls of the intestine to be absorbed. The small intestine is very long so that the nutrients will have more time to be absorbed into the body as they pass through.
Why is the small intestine in a frog so long?
They need long small intestines so the fibrous material has more time to digest and be absorbed. You can see their coiled intestines through their translucent skin.
How does the structure of the small intestine help it absorb nutrients?
Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.
How does the small intestine structure relate to its function?
The small intestine is a tubular structure within the abdominal cavity that carries the food in continuation with the stomach up to the colon from where the large intestine carries it to the rectum and out of the body via the anus. The main function of this organ is to aid in digestion.
How does the small intestine increase its surface area?
The interior walls of the small intestine are tightly wrinkled into projections called circular folds that greatly increase their surface area. Microscopic examination of the mucosa reveals that the mucosal cells are organized into finger-like projections known as villi, which further increase the surface area.
How does the small intestine move digest and absorb food?
The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.
How long is the small intestine of a frog?
A frog’s small intestine is about twice its body length. Most tadpoles eat algae and plants. They need long small intestines so the fibrous material has more time to digest and be absorbed. You can see their coiled intestines through their translucent skin. Their intestinal length is about ten times their body length.
How does the length of the small intestine relate to its absorption?
Because nutrients in food are absorbed into the body through diffusion or active transport, the nutrients must come into contact with the walls of the intestine to be absorbed. The small intestine is very long so that the nutrients will have more time to be absorbed into the body as they pass through.
What kind of food does a frog eat?
Depending on their size, frogs eat insects, worms, small snakes, and mice. Their diet is mostly protein, which is much easier to digest than fibre. Adult frogs can therefore have a shorter small intestine. It is only about twice their body length.
What happens when food reaches the large intestine?
By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place. What’s left is mainly fiber (plant matter which takes a long time to digest), dead cells shed from the lining of your intestines, salt, bile pigments (which give this digested matter its color), and water.
