Digestive System

A bolus is a small round mass of a substance.

Digesting a banana is a chemical change because enzymes in your digestive system break down the complex molecules in the banana into simpler molecules that your body can absorb for energy. This process involves a chemical reaction that results in new substances being formed.

1) nitrogen fixing bacteria convert atmospheric nitrogen to nitrites and nitrates for plants.

2) some bacteria are involved in anaerobic respiration that are responsible for converting milk to yougurt.

Enzymes in the digestive system and hydrolases are both types of proteins that catalyze chemical reactions to break down molecules. Specifically, hydrolases are a subset of enzymes that catalyze hydrolysis reactions, breaking down molecules by adding water.

Having a single opening for both ingestion and elimination can increase the risk of contamination and infection from waste material. It can also limit the efficiency of digestion and nutrient absorption, as food may not be fully broken down before being expelled. Additionally, this type of digestive system may restrict the size and complexity of organisms that can be sustained due to the limitations in processing food.

The digestive system of a cockroach consists of a long alimentary canal that runs from the mouth to the anus. It includes structures such as the crop for storing food, the gizzard for grinding food, and the midgut for digestion and absorption of nutrients. Waste materials are eliminated through the anus.

The stomach is part of the digestive system, where it plays a central role in breaking down food through the secretion of gastric juices and mixing movements. It is also involved in the endocrine system, producing hormones like ghrelin that regulate hunger and satiety.

No, fiber is a type of carbohydrate that is not easily digested by the body. It passes through the digestive system intact, aiding in digestion and promoting overall gut health. Complex carbohydrates are starches that take longer to break down compared to simple sugars.

When protein is pre-digested, it is broken down into individual amino acids or smaller peptide chains. This makes it easier for the body to absorb and utilize the protein for various cellular functions, such as muscle building and repair.

Digesting a candy bar involves both physical and chemical processes. Physical processes include chewing and breaking down the food into smaller pieces, while chemical processes involve enzymes breaking down the food into smaller molecules that can be absorbed by the body.

No actually i am a Doctor at the Doctor Associations of Australia and i deal with organs, it is more of a balloon with a smooth texture. Compared to a large intestine.

Enzymes are chemicals that speed up the breakdown of food into usable forms in our bodies. They help to break down complex molecules like proteins, carbohydrates, and fats into simpler molecules that our cells can absorb and use for energy and other essential functions.

Pre-digestion of proteins breaks down large protein molecules into smaller peptides and amino acids. This process improves the bioavailability and absorption of proteins in the body, making them easier to digest and utilize for various functions such as muscle building and repair.

During the final stage of CO2 car production, finishing touches are added to the car, such as decals and paint. Quality checks are performed to ensure that the car meets performance standards. The completed CO2 car is then ready to race.

Tissues in the digestive system, like the mucosa and submucosa, help with nutrient absorption and secretion of digestive enzymes. Cells such as epithelial cells line the gastrointestinal tract and aid in nutrient transport. Overall, tissues and cells work together to facilitate digestion, absorption, and processing of nutrients in the body.

Food is broken down into usable forms in the digestive system through the process of mechanical digestion (chewing and churning) and chemical digestion (enzymatic breakdown of molecules). This allows nutrients to be absorbed across the walls of the digestive tract and into the bloodstream for use by the body.

Microvilli and tight junctions are two structures present in epithelial cells from the small intestine that are not present in cholera bacteria. Microvilli increase the surface area for nutrient absorption, while tight junctions help to form a barrier between cells to regulate the passage of molecules. Cholera bacteria cause an infection in the intestine but lack these typical cell structures as they are single-celled organisms.

sugar
Starch is a carbohydrate.Starch is broken down into moltose or glucose.
Starch is broken down into glucose by enzymes during digestion. Starch is a polysaccharide that must be broken down into a simple sugar called a monosaccharide. Glucose is a monosaccharide.

Peristalsis is the process of muscular contractions in the walls of the digestive tract that helps propel food down the gastrointestinal tract. It allows for the movement and digestion of food through the esophagus, stomach, intestines, and ultimately out of the body.

The food you are eating changes state. The food is a solid but it get its state changes by you chewing food. Changing state is making a chage in apperance. So in a way it is a chemical change

If that answers your question, your welcome!!

Both flukes and cnidarians possess a gastrovascular cavity for digestion. This cavity serves the purpose of digestion and distribution of nutrients throughout the organism's body.

Yes, emulsification increases the surface area of fat particles, making it easier for enzymes to break them down into smaller molecules, which can help in the digestion of fats. This process allows enzymes, like lipase, to work more effectively and efficiently on breaking down fats into absorbable components.

The process of cellular respiration breaks down food molecules to produce ATP. This process involves breaking down glucose to release energy which is used to form ATP through a series of biochemical reactions in the mitochondria of the cell.

The structure responsible for the restriction of movement of large complex substances into the bloodstream is the endothelial cells that line blood vessels. These cells form a barrier known as the blood-brain barrier, which regulates the entry of substances from the bloodstream into the brain and spinal cord to protect the central nervous system.

The small intestine is part of the digestive tract or gut. It is where most of the digestion and absorption of nutrients from food occurs.
