are different systems working together and form a human body work permit. One of this system is the important digestive system which consist of a cluster of organs‚ including the mouth‚ stomach and intestines. These organs allow the digestion of food. That means that digestion? It is a process of breaking down food into smaller components to make it easier absorption. There are three main steps in the digestive process: ingestion‚ digestion and absorption. The first step of the digestive process occurs

However to the digestive system I am carbohydrates‚ fat‚ and protein. When I am consumed‚ most of me is distributed in your body. However‚ what s not useful is expelled. The digestive system is meant to ingest food through your mouth‚ digest it is by breaking it down‚ ingest it to your bloodstream‚ and lastly excrete it through the anus. In this essay I will guide you through these four phases. Bread is made out of carbohydrates. In the digestive system‚ carbohydrates start the digestive process in

process of converting the food you eat into nutrients that your body can use for energy‚ growth and cell repair needed for survival. The digestion process not only takes in nutrients but also eliminates the waste products from your food. The digestive system is a series of long twisted tubes that start at your mouth and goes all the way down to your anus. It’s made up of different tissues that have important functions in breaking down the food. Here is where the whole process starts‚ the mouth

6 primary functions of digestive system: 1. Ingestion- food intake 2. Secretion 3. Digestion- mechanical & chemical breakdown of food Mechanical Mastication- first step. Enables mixing with saliva to form bolus to be swallowed. Regulated by CNS. Deglutition Mixing/Churning Peristalsis- movement of muscles within GI tract that facilitates movement of food Chemical- Hydrolysis (using H2O) of macromolecules into monomers (residues) carried out by digestive enzymes produced by salivary glands

Parts of the digestive system The digestive system consists primarily of the alimentary canal‚ a tube that extends from the mouth to the rectum. As food moves through this canal‚ it is ground and mixed with various digestive juices. Most of these juices contain digestive enzymes‚ chemicals that speed up reactions involved in the breakdown of food. The stomach and the small intestines‚ which are parts of the alimentary canal‚ each produce a digestive juice. Other digestive juices empty into the alimentary

This essay will explain the function of the respiratory‚ digestive and cardiovascular systems and how they work together to produce nutrients and oxygen to the cells for cellular respiration (energy for the body) The first system in the body is the digestive system. When food enters the mouth the salivary glands secrete saliva which mixes with the food. This makes it easy to chew and swallow. Once the food has been chewed enough the food travels down the oesophagus to the stomach. Once the food

Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

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‚ but unconsciously regulated by the autonomic nervous system through the release of neurotransmitters
