When rationally thinking about the gastrointestinal tract or digestion‚ nearly all of its functions are regulated by the autonomic nervous system‚ or involuntary‚ meaning that we do not consciously have to contemplate digestion for digestion to occur. With this being stated‚ it would make sense that almost the entire gastrointestinal tract is made up of smooth muscle. Smooth muscle is very distinctive from the other types of muscle in the body due to the fact that it is not controlled consciously

Ad1 Digestion is the mechanical and chemical breaking down of food into smaller components‚ to a form that can be absorbed‚ for instance‚ into a blood stream. Digestion is a form of catabolism; a break down of macro food molecules to smaller ones. The digestive process also involves creating waste to be eliminated. The digestive track (gut) is a long twisting tube that starts in the mouth and ends at anus. It’s made up of a series of muscles that coordinate the movement of food and other cells that

BIOLOGY ‘S ASSIGNMENT 1/What is the purpose of digestion? * Break down food‚ absorb nutrient from food into body tissues and systems in body 2What is the name given to mammal only eat meat ? * Carnivores 3/What is the name of mammal only eat plant? * Herbivores 4/What is the difference between a fore-gut fermenter and hind-gut fermenter? Example? Because plant cells have tough cellulose cell walls and herbivore are not able to digest‚ they use micro- organisms that live symbiotically

average person eat food we don’t think about all the things your body have to do just to digest what we ate this short essay I will explain to you the process of how we digest food. Digestion times vary between people but on the average it takes 24-72 hours for our body’s to digest food. The first process with digestion is ingestion which means the chewing process while we chew food it’s broken up in the mouth with saliva and forms into a ball for swallowing called bolus the amylase in our saliva

ingested‚ poultry may also swallow small rocks. These rocks aid in the grinding of harder feed particles in the gizzard. Feed passes from the gizzard into the small intestine‚ where additional enzymes are added and digestion occurs. The small intestine also serves to absorb digestion products (proteins‚ carbohydrates‚ and fats). You should notice in the photo above that the first part of the small intestine loops around the pancreas (called the duodenal loop). The pancreas secretes digestive enzymes

The Circulatory System The Circulatory System is designed to deliver oxygen and nutrients to all parts of the body and pick up waste materials and toxins for elimination. This system is made up of the heart‚ the veins‚ the arteries‚ and the capillaries. Circulation is achieved by a continuous one-way movement of blood throughout the body. The network of blood vessels that flow through the body is so extensive that blood flows within close proximity to almost every cell. Heart The heart

Polymers are insoluble and therefore cannot be absorbed into our bloodstream and need to be assimilated into different absorptive products. Polymers have to be hydrolysed into smaller‚ soluble molecules. This process happens during the process of digestion. Food is broken down by mechanical or chemical means (Hydrolysis) and this process is aided by Enzymes. Enzymes are biological‚ process catalysing Proteins which massively speed up the breaking down of compound molecules into micromolecules to allow
