What else can I help you with?
How do nutrients and pass into a cell?
Osmosis (when nutrients go from a high concentration of nutrients to a low concentration) and phagocytosis (when the cell actually eats it)
When the metal ball is heated can it go through the metal ring?
when the ball is heated, it will pass through the unheated ring.
What is the ability of a membrane to allow materials to pass through called?
Permeable if anything can go through or semipermeable if only certain things can go through it.
Where are villi present in the human body and what are their functions?
Villi are largely present in the lower digestive tract. Their function is not only to absorb the digested foodstuffs but also they greatly increase the surface area for absorption.
What two straits would you pass through to go from the Aegean Sea to the Black Sea?
To go from the Aegean Sea to the Black Sea, you would pass through the Dardanelles Strait and the Bosporus Strait. The Dardanelles connects the Aegean Sea to the Sea of Marmara, and the Bosporus connects the Sea of Marmara to the Black Sea.
How does the composition of blood changes as it flows through the villi?
The blood flow in through the villi changes in an increase as the intestine near the villi is wide to go through.
Who does the small intestines help with digestion?
the lengthb increase the surface area so that it can better absorb nutrients
Where do the nutrients that pass through the small intestine wall go?
it goes trough the bloodstream
What does does villi do in digestion?
The wall of the small intestine has folds that bear fingerlike prjections called villi. Villi in turn have projections called microvilli. The products of digestion are absorbed by microvilli and they enter the blood capillaries and the lacteals of the Villi.
What were does the nutrients go to after going through villi?
Villi are finger-like projections on the lining of the small intestine. After digestion is finished off, the nutrients and digested food goes to the villi, then from the villi to blood capillaries. Blood capillaries are small blood vessels that contain tiny holes through with tissue fluid leaks out. Then, the nutrients go from the blood capillaries to the tissue fluid. The tissue fluid is mainly water, it surrounds the tissues in our body and it forms a continuous link between the blood plasma (liquid part of the blood that helps the blood to circulate) and the cells. After going to the tissue fluid, the nutrients go to the blood plasma and then to the cells where it is used up (oxygen and chemicals from our food is separated from waste materials and carbon dioxide) Arteries carry oxygen from the blood cells to the body cells and veins carry carbon dioxide. After going to the cells, the nutrients go to the tissues. Hope this helped. I was also confused first but then my teacher explained it to me. :)
Were does blood go to get nutrients?
the nutrients enter the blood in the small intestine. The lining of the small intestine is called the villi, that is were the blood is absorbed into the bloodstream
Finger-like structures that cover the inner wall of the small intestine?
These are called villi and there are millions of them that line the small intestine and large intestine (Colon) they absorb the nutrients particularly in the Colon where they absorb liquid into the blood stream. This is what makes your stools hard (constipation) and painful to pass if you wait too long to go for a number 2. The peristaltic action moves the liquid along the small and large intestines.
From the maternal capillaries nutrients diffuse into the capillaries of the chorionic villi and go to the fetus via the?
Umbilical cord or if old enough put on a mirror and snort it
How do nutrients and pass into a cell?
Osmosis (when nutrients go from a high concentration of nutrients to a low concentration) and phagocytosis (when the cell actually eats it)
How are the small intestines adapted for diffusion?
- The small intestine needs a large surface area as it is adapted for absorbing nutrients from food that the body needs. - The small intestine has villi, which increase the overall surface area, maximizing the area available for absorbing nutrients. - The villi have very good blood supplies, as they each have a capillary in them, so when substances are diffused they go straight into the blood stream. Just like the alveoli in the lungs, the epithelium is only one cell thick meaning that there is less distance for the nutrients to diffuse across. I think there might be more information about this on the BBC Bitesize website, but in the meantime I hope this helps
What structure increase surface area for absorption of nutrients?
The structure that increases surface area for absorption of nutrients in the small intestine is called the villi. Villi are tiny, finger-like projections that line the inner wall of the small intestine and are covered in even smaller hair-like structures called microvilli. Together, villi and microvilli greatly increase the surface area available for the absorption of nutrients from digested food.
Where are proteins absorbed?
Enzymes, Glucose and The Protein work together to enter the body then go through the small intestine and rubbing onto the villi
