What is extraoral digestion?
What is extraoral digestion?
Extra-oral digestion means that spiders are able to break down the nutrients of captured prey outside their own body. Accordingly, they can both digest large amounts of tissues and separate indigestible parts, such as the exoskeleton of the prey, before they ingest it.
How do insects digest food?
All insects have a complete digestive system. This means that food processing occurs within a tube-like enclosure, the alimentary canal, running lengthwise through the body from mouth to anus. Ingested food usually travels in only one direction.
Why do we study the digestive system of an insect?
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. The alimentary canal has specific sections for grinding and food storage, enzyme production, and nutrient absorption. Sphincters control the food and fluid movement between three regions.

Which is the correct column for digestion and absorption?
Column I Column II 1. Glycine and glucose Small intestine and active absorption 2. Fructose and Na + Small intestine passive absorption 3. Glycerol and fatty acids Duodenum and move as chilomicrons 4. Cholesterol and maltose Large intestine and active absorption To view explanation, please enrol in the course below.
How does extra-oral digestion in terrestrial Arthropoda work?
Through the injection of potent hydrolytic enzymes, either by refluxing or nonrefluxing application, these predators greatly increase the efficiency of prey extraction and nutrient concentration.
Where does the next step of digestion take place?
The next step of digestion (nutrient absorption) takes place in the remaining length of the small intestine, or ileum (> 5 meters). Figure 2.3. 3: The way the small intestine is structured gives it a huge surface area to maximize nutrient absorption.
How does fat digestion and absorption take place?
Fat digestion and absorption take place in a different manner than the other two building block of cellular components. The following is a brief summary. Lipids are hydrophobic in nature and that is why they are poorly soluble in the aqueous environment of the digestive tract. Their digestion is initiated by lingual and gastric lipases.
