What is the process of soluble food substances crossing the gut lining?
absorption
Does the bacteria in the large intestine feed on the material passing through and make certain vitamins for the body?
Yes. Bacteria also make substances that facilitate absorption of food ingredients.
How does the structure of villi adapted to its function?
- villus increase the surface area over which food is absorbed - an epithelium, consisting of only on thin layer of cells, is all that foods have to pass through to be absorbed - protrusions of the epithelium cells increase the surface area for absorption. This projections are referred to as microvilli - protein channels in the microvilli membranes allow rapid absorption of foods by facilitated diffusion and pumps allow rapid absorption by active transport - mitochondria in epithelium cells provide the ATP needed for active transport - blood capillaries inside the villus are very close to the epithelium so the distance for diffusion of foods is very small - a lacteal in the center of the villus carries away fats after absorption
Are fungi heterotrophic by absorption?
Yes they are. First, the fungus grows hyphae into a food source. Then digestive chemicals ooze from the hyphae into the food. The digestive chemicals break down the food into small substances that can be absorbed by the hyphae. Source: Prentice Hall Science Explorer: From Bacteria to Plants
What are the important food substances?
Carbohydrates, Protiens, fats, vitamins,minerals and water are the most essential food substances.
How is the epithelium suited for the absorption of food substances?
they have partially permeable membrane which help in absorbtion
How is assimilation different from absorption of nutrients of digested food?
Absorption is whereby the digested food substances are entering our bloodstream. Assimilation is whereby the body makes use of these absorbed food substances that has entered our blood
What is the process of soluble food substances crossing the gut lining?
absorption
What is called digestion?
The breakdown of complex components of food into simpler substances is called digestion.
How is the earthworms digestive system adapted for extracting relatively small amounts of food from large amounts of ingested soil?
The gizzard is a muscular organ used to churn the food and then it moves onto the intestine where absorption of the food occurs.
List 2 ways the ileum adapted role in absorption?
1)Villi and micro villi increase the surface area for the absorption of digested food. 2)Epithelial cells lining the intestine have a high volume density of mitochondria, meaning lots of energy for the active uptake of digested food. :)
How is the small intestings adapted to increase absorption of food?
The cells that line small intestines have small projections on their surface called villi. These projections collectively increase the total surface area of the small intestine. This adaptation facilitates increased absorption of nutrients
The movement of digested food into the blood or lymph is?
absorption. Mastication is chewing the food and Deglutition is swallowing
What organ is responsible for food and water absorption?
The villi in the small intestine assimilated dissolved food. Villi increase the internal surface area of the intestinal walls, allowing for a larger area of absorption.
How is ileum of a mammal adapted for the absorption of digested food?
1/ the lining has A a very large surface area. 2/ the length of the intestine (ileum 3.5m) help increase the surface surface area for absorption. 3/ millions of villi provide a large surface area in contact with the digested food. 4/ hundreds of micro villi on the surface cells (on each villus) increase the surface area for absorption. your welcome :)
Does the bacteria in the large intestine feed on the material passing through and make certain vitamins for the body?
Yes. Bacteria also make substances that facilitate absorption of food ingredients.
Two substances are mixing together with food in the duodenum?
Secretin and Cholecystokinin are released from cells in the duodenal epithelium in response to acidic and fatty stimuli present there when the pylorus opens and releases gastric chyme into the duodenum for further konadigestion.
