Which molecules are passively absorbed into the blood?
Small, non-polar molecules like oxygen, carbon dioxide, and water can passively diffuse through cell membranes and be absorbed into the blood. Lipid-soluble molecules and small uncharged molecules can also passively cross cell membranes to enter the bloodstream.
Are bilipid layers normally permeable to small or large molecules?
Bilipid layers are selectively permeable to small molecules that are non-polar or lipid-soluble, while they generally restrict the passage of large molecules and polar compounds. This selective permeability allows for the regulation of what substances can enter and exit the cell.
How does the absorption of a water-soluble molecule differ from that of a fat-soluble molecule?
Water-soluble molecules are absorbed through passive diffusion or facilitated transport in the intestines, while fat-soluble molecules are absorbed with the help of bile salts and form micelles for absorption through simple diffusion in the small intestine. No specific transporters are needed for fat-soluble molecules due to their ability to pass through the cell membrane easily, unlike water-soluble molecules which require specific transporters for absorption.
What kind of molecules cannot pass into your blood?
Large Food Molecules in The Small Intestine!
Why is ethanol soluble in blood?
Ethanol is soluble in blood because it is a small molecule that can easily pass through cell membranes and dissolve in the water-based environment of the blood. This allows ethanol to be distributed throughout the body and reach various tissues and organs.
How do the molecules get into the blood vessels?
The small, soluble molecules get through the wall of the small intestine and into the blood

Where small soluble molecules absorbed into the body?
The small Intestines :D

What statement best describes extracellular digestion?
large insoluble molecules are converted to small soluble molecules outside the cell
What happen when you digestive food?
Digestion is the breakdown of large food molecules into small, water-soluble food molecules that can be absorbed.
Where does assimilation of food molecules into the blood take place?
Assimilation of food molecules into the blood takes place in the small intestine. The small intestine is lined with villi and microvilli, which increase the surface area for absorption. Nutrients are absorbed through the walls of the small intestine and then enter the bloodstream to be distributed to cells throughout the body.
When soluble substances pass through the small intestine and into the blood?
enzymes

Do fats and water soluble molecules such as sugars get absorbed from the intestine directly into the blood?
The simple sugars do but not the fats. The presence of fat in the small intestine produces hormones that stimulate the release of pancreatic lipase from the pancreas and bile from the liver which helps in the emulsification of fats for absorption as fatty acids.
Where does food enter the blood vessesles?
usually nutrients enter the blood vessels through the small intestines
