1. The small intestine is LONG- this ensures food remains in the small intestine long enough for the products of digestion to be fully absorbed into the bloodstrem.
2. The Small intestine is HIGHLY FOLDED into villi (s. villus)- This gives a greater surface area for more efficient diffusion of products into the bloodstream.
3. The small intestine has a RICH BLOOD SUPPLY - Each villus has a network of capillaries so that the products of digestion are carried away from the small intestine efficiently.
4. The epithelium of the small intestine in the villi is only ONE CELL THICK - for easier diffusion of the products of digestion into the bloodstream. The walls of the capillaries are only one cell thick as well!!

Which protozoan organelle is responsible for digestion?
The organelle primarily responsible for intracellular digestion.
What cellular structures is involved in intracellular digestion Golgi apparatus ribosomes lysosomes?
The main cellular structures involved in intracellular digestion are lysosomes and the Golgi apparatus. Lysosomes contain digestive enzymes that break down complex molecules, while the Golgi apparatus modifies and packages these enzymes for transport to the lysosomes. Ribosomes are responsible for protein synthesis and do not directly participate in intracellular digestion.
Is proteins the major intracellular anion?
No; the major intracellular anion is phosphate.
Why are viruses intracellular?
viruses are intracellular because they need to use cells to replicate themselves
What do intracellular receptors do?
The intracellular receptors differ from membrane receptors based on their location. Membrane receptors are usually on the plasma membrane but the intracellular receptors are found inside the cell.
Do mollusks undergo extracellular digestion or intracellular digestion?
Intracellular
What is the primary site of the intracellular digestion?
The primary site of intracellular digestion are the lysosomes.
Organism which utilizes intracellular digestion?
Unicellular eukaryotes achieve intracellular digestion through the process of endocytosis, phagocytosis, and use of food vacuoles and lysosomes. A paramecium is an example of an organism that uses intracellular digestion vs. humans which utilize extracellular digestion.
Is paramecium digestion extracellular?
No. its intracellular.
Can fungi carry out intracellular digestion?
YES
What type of digestion system do paramecium have?
intracellular
Is centipede digestion extracellular or intracellular?
extracellular
Do all vertebrates have intracellular digestion?
Nope.
Contains enzymes for intracellular digestion?
Lysosomes
Is earthworm digestion extracellular or intracellular?
It is extracellular
What organisms do extracellular and intracellular digestion?
humans
What advantage is there to the extracellular digestion of cnidarians over the intracellular digestion of sponges?
