How does digestion of carbohydrates and proteins take place in your body?

The digestion of carbohydrates (starches and sugars) and of protein is so different, that when they are mixed in the stomach they interfere with the digestion of each other. An acid process (gastric digestion) and an alkaline process (salivary digestion) can not be carried on at the same time in an ideal way in the stomach. In fact, they cannot proceed together at all for long as the rising acidity of the stomach contents soon completely stops carbohydrate digestion and this is followed by fermentation.

What are the Organs where mechanical digestion take place?

There is the small intestine, stomach, and the mouth, and that is all that i can think of.

Hope this answer helps you people out there looking for three of the organs for mechanical digestion. But if not....... well that sucks for you.

How many steps are there in the digestive system?

There are 7 general steps associated with locations in the body:

1. The mouth (chewing and salivary glands)

2. The esophagus (swallowing and entering the stomach)

3. The stomach (digestion by acid)

4. and 5. The small intestine

(digestion by bile and pancreatic enzymes - duodenum)

(absorption of nutrients - jejunum and ileum)

6. The large intestine (absorption of water and nutrients)

7. The rectum (waste elimination)

What is the exit for digestive waste?

The opening at the end of the digestive system from which easy exit body is called the anus.

What is the role of the teeth in digestion?

The role that the teeth play is that they chew the food up so that it is easier to swallow the food also so you don't choke (did you know that your strongest muscle it in your mouth)

---------------

I think they break down food mechanically, increasing the surface area of the food for enzyme action.

What does the mouth digest?

The enzymes in the saliva in the human mouth starts digestion on starches, turning them into sugars.

During digestion foods do not pass through the?

The Liver. The liver only passes bile (fats) to the gallbladder and then to the small intestine

Why doesn't the owl digest the whole thing instead of making a pellet?

Whilst owls have a strong acid in their stomach, it is not strong enough to digest all of the fur, feathers or larger bones, though softer bones are digested.

Digestive system connected to?

Urinary is the first that comes to mind...you drink something, then must excrete it via the kidneys/urine. But as I sit here and think about it, the pancreas comes to mind, which is part of the endocrine system as well as digestive... The pancreas is responsible for most of the enzymes that are used during digestion. So I guess it would go endocrine, digestive, then urinary.

How is a shadow related to absorption?

A shadow is what we call the absence of light due to some object coming in between the light source and surface on which the "shadow" falls.

The 'object' which was in the way of the light could be, for example, solid rock or colored glass.

Both block the direct path of the light, but at different rates and in different ways.

The rock, would absorb a great proportion of the light due to its high density.

The glass however, is less dense, therefore light passes through it more freely, with less of it being absorbed. Therefore more of it continuing to finally reach the surface.

So to a certain degree, shadows are directly related to the physical makeup of the shadow casting object. The more the object absorbs, the darker the shadow will be and vice versa.

There are phenomena I've chosen to leave out of my answer for simplicity. But you could start looking into volume properties and terms such as scattering, emission, extinction, optical density in addition to absorption.

How is the integumentary and the digestive system connected?

The digestive system is connected with thecirculatory system because nutrients pass through the blood and it is also connected to the excretory system because it gets rid of excess waste products. The integumentary system is connected with the excretory system because sweat is a waste product and it is is getting removed. It is also connected to the muscular system and skeletal system.

How is fecal matter produced?

Poop, or feces, is composed of indigestible food waste, enteric bacteria, and water.

What does the digestive system produce?

The digestive system creates alot of juices. like Gastric juices, digestive juices in the schmach such as hydrochloric acid. Also Insulin, Enzymes, Saliva, and Bile.
