It is a strong mineral acid with many industrial uses. Hydrochloric acid is naturally found in the gastric juices of the stomach. The most important role of hydrochloric acid is to break down the foods and cause the release of enzymes that further
Some examples are the circulatory, the excretory, the muscle, and the digestive systems. For example, the digestion system is an organ system that digests the food a person eats. Some organs in the digestive system are the esophagus, rectum, stomach, liver, gall bladder, pancreas, large intestine, small intestine, and appendix. The digestive system is very important because without it, organisms would not be able to digest food. Food would just sit inside the body or go through it without the body taking any energy for fuel.
The false feet first go out and then the body follows in a kind of oozing motion. The amoeba eats smaller protists, animals, and plants. It captures then in their false feet and slowly increases it in itself so it can not move anymore. Then it passes through the cell wall and membrane and then the food goes into a vacuole which can store oxygen, food, or liquid.
each section incorporates hundreds of microscopic tapeworm eggs. these eggs can be ingested via food contaminated with the faeces. once the eggs had been ingested, they grow to be larvae, which could migrate out of the intestines and shape cysts in other tissues along with the lungs or liver. tapeworm contamination also can be caused by ingesting uncooked or undercooked meat from an animal that has the larvae of the tapeworm, grouped in cysts in its muscle groups. as soon as ingested, the larvae then change into person tapeworms in the intestines.
The process of peristalsis starts in the oesophagus when a bolus of food is gulp down. The food is brought to the stomach by the strong wave-like motions of the smooth muscle in the oesophagus, where it is churned into a liquid compositioncalled chyme. The process of peristalsis proceeds in the small intestine where it blends the chyme byits to and fro motion and here nutrients are absorbed into the bloodstream through the small intestine walls. Peristalsis ended in the large intestine where water is absorbed into the bloodstreamfrom the undigested food constituent. Finally, the residual waste products are expelled from the body through the rectum and anus.
The alimentary tract of starts from mouth, there they have beak for breaking the prey’s shell and it is broken down to small pieces in that buccal mass consisting of mouth, pharynx, radula and salivary glands. Salivary glands secrete digestive enzymes while another pair secretes a toxin which paralyses the prey making it easy. Then food passes through oesophagus which has more digestive glands and transferred to crop which is a temporary storage of partly digested food before it enters the stomach. Stomach is a very muscular organ here the food is churned up into a slush in the stomach and it enters the caecum.
Digested molecules of food, as well as water and minerals from the diet, are absorbed from the cavity of the upper small intestine. Most absorbed materials cross the mucosa into the blood and are carried off in the bloodstream to other parts of the body for storage or further chemical change. As already noted, this part of the process varies with different types of nutrients. 5. 2) Page B13, and #1-4 1.
Introduction: The salivary glands are exocrine glands which have two functions,firstly is the production of saliva which helps the passage of food through the oesophagus to the stomach, secondly the salivary enzymes which are responsible for the breakdown of nutrients so it is responsible for the first step of digestion. The salivary glands are divided into major and minor groups. The major glans are three pairs which are the parotid, submandibular and sublingual while the minor glands are numerous and scattered in the nasal and oral cavities, paranasal sinuses, soft palate, larynx and pharynx.
These bacteria feed on vitamin B12, so it reduces the amount of vitamin B12. In the second stage of the normal body, vitamin B12 moves to the duodenum and combines with IF after releasing from proteins. Then it enters the small intestine up to the ileum (the last part of the small intestine) to break the IF, and absorb vitamin B12. However, in the second stage of pernicious anemia, the immune system becomes overactive. As a result, intrinsic factor antibodies form and attack IF and destroy them.
Jaundice is more apparent in the whites of the eyes. 4. Mrs. Fender’s prolonged clotting times and excessive bruising are related. Again, referring to normal physiological functioning of the liver, why do these two things happen when alcohol damages
Entering the through the Lower esophageal Sphincter (LES) wasn’t entertaining but once you get in it’s like rippled effect of the water except that is a combination of red and pink. We’re finally in the stomach we will just hang in here an hour or two. Once we travel through the Rugae it will produce the enzyme Pepsin. So I can be prepared for the small intestine. First we will be going to the small intestine but first we will go to the duodenum.
Introduction: Dissections are performed on preserved animals donated specifically for science education in order to provide a hands-on experience to observe and study anatomy of an animal in three dimension, unlike a textbook, and how the organ systems are interconnected. In this particular dissection a fetal pig was used because the organs present in a pig, and their position in the body are similar to those of humans which provides insight on how human organs systems work overall and why they are essential to life. The purpose of our experiment was to focus on the external, digestive, cardiovascular, respiratory, and excretory systems of the fetal pig to understand how theses system work together in order to sustain life. Materials & Procedure:
Wolxy s(Vulpes Lupus) are the offspring of a red fox and a gray wolf. Both parents are members of the kingdom Animalia which makes their offspring a member of the kingdom Animalia as well. The offspring follows the same classification of its parents which is domain: Eukarya, phylum: Chordata, class: Mammalia, order: Carnivora, and family: Canidae. This offspring, like its parents, is a vertebrate which means that it has an endoskeleton that is supported by skeletal muscle tissue. It also has loose connective tissue and epithelial tissue that connects and protects its vital organs.
