The digestion process begins when we bite into our food. We chew our food so that we can break it into smaller pieces, which make it simpler for the body to digest. The following four layers create the esophagus: the mucosa, submucosa, muscularis, and tunica adventitia. Collectively, the mucosa and submucosa build elongated folds. During digestion, the esophageal lumen is occupied with the food and liquids we swallow. However, when we are not swallowing, the elongated folds work to close…
Cystic Fibrosis Presentation Cystic fibrosis is genetic disorder. It is an inherited disorder that can result in a severe damage to the respiratory and digestive systems. This disorder can affect the lungs, pancreas, intestines, liver and even the sex organs. Cystic fibrosis builds up a thick and sticky mucus in the lungs and other respiratory and digestive organs in our body. For an infant to be at risk of developing Cystic Fibrosis, both parents must pass on the abnormal gene to the infant.…
An enzyme is a biological catalyst; catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes also make the reaction take place more often, and are needed in small amounts; they are also neither reactants nor products. Enzymes are also proteins that are folded into complex shapes that allow molecules to fit into them. The enzymes that are involved in respiration, photosynthesis and protein synthesis work within cells whereas other enzymes are secreted…
energy and nutrients that are needed in the body. The digestive system is made up of the alimentary canal which include the mouth or oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines including the accessory organs of digestion which involve the teeth, tongue, salivary glands, liver, gall bladder and the pancreas. The alimentary canal and the accessory organs perform the following functions which include; ingestion, secretion,…
website, “Digested material may be transported into blood vessels in the wall of the small intestine by the processes of simple/passive diffusion, facilitated diffusion, primary active transport, or secondary active transport.” (2016, para. 12). So digestion means the process where food and drink are broken down into very small pieces in order for the body to be able to use them sustain cells and for energy.…
tend to gain weight. Chewing gum can help you not directly but covertly. Whenever crave for a snack pop a gum into your mouth. It has far less calories than other snacks and hence will not add pounds and calories and ruin your diet. IT CAN AID IN DIGESTION If you chew on gum after meals it will be very helpful. When you chew gum the flow of saliva also increases and so does the act of swallowing. Saliva helps to ease the acid that is formed in your stomach and will prevent heart burn. If you…
number of different mechanisms. However, this process is largely contrived through two means, parietal cells and drugs. Utilized each day in processes like digestion and metabolism, the role parietal cells and drugs play in regulating gastric acid secretion is fundamental to life. Gastric Acid Secretion by Parietal Cells Gastric acid aids digestion by creating the optimal pH for pepsin and gastric lipase and by stimulating pancreatic bicarbonate secretion. Acid secretion is initiated by food:…
Without a doubt, cellular respiration, the process of converting energy from nutrients into ATP and then releasing waste products, is important to the human body. In fact, many of our organ systems wouldn’t even be able to function if it weren’t for cellular respiration. These include the excretory, respiratory, digestive, and circulatory systems, which carry out some of the most significant actions. Additionally, the body needs mitochondria to produce ATP in order to power cells and enable them…
Our human body consists of several different types of organs for example, lung, heart and kidney each organs have specific function that they carry out. Small part of the cell which is called organelles, they have been adapted to carry out certain function and this can be more than one. Organelles are found in eukaryotes and they are always surrounded by protective membrane. Mitochondria which is the organelle it acts like a digestive system because it takes in all the nutrients, breaks them…
First, Nellie, you must understand that our bodies make lots of different hormones. A hormone is usually a special protein that certain cells in the body make. Once the hormone is made, it enters the blood so it can travel to where ever it is needed in the body to make a specific thing happen. The body continues to make more of the hormone as needed in order to make happen what it is the hormone does. Certain cells make one type of hormone, while other cells make a different type of hormone…
