Excretory system DEFINITION The excretory system is a passive biological system that removes excess‚ unnecessary materials from an organism‚ so as to help maintain homeostasis within the organism and prevent damage to the body. It is responsible for the elimination of the waste products of metabolism as well as other liquid and gaseous wastes‚ as urine and as a component of sweat and exhalation. As most healthy functioning organs produce metabolic and other wastes‚ the entire organism depends on

Discussion: The goal of surgical management for perianal fistula is to effectively eradicate current and recurrent septic foci‚ associated epithelialized tracts and preserve continence. No single technique achieves these aims for all types of anal fistulas. It is often necessary to balance the degree of sphincter division and continence disturbance. An ideal procedure for treating a fistula-in-ano should be minimally invasive with minimal failure rates and morbidity. 12 Based on the data available

Zachary’s Story A. An ulcer starts by eroding the mucosa of the G.I. tract wall. What functions of digestion and/or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the sub mucosa and then the muscularis? a. Absorption would not happen correctly some of the ingested and secreted may seep out of the lumen. This also could create a pathway of entry for pathogens if the ulcer ate through to the muscularis mucosa. You

of hollow organs working together extending from the mouth to the anus. These hollow organs are the mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine‚ large intestine‚ rectum‚ and anus. These hollow organs make up the gastrointestinal (GI) tract. The GI tract is aided by four accessory organs‚ the salivary glands‚ liver‚ gallbladder‚ and pancreas. (Johnson) There are five basic processes of the digestive system. These processes are motility‚ secretion‚ digestion‚ absorption‚ and excretion. Motility

human body. The brain’s first structure is the myelencephalon‚ which is also called the medulla. The myelencephalon is known as the most posterior part of the brain. The structure of the myelencephalon is made up of bundles of axons called tracts. These tracts carry signals between the rest of the body and the brain. The myelencephalon also contains a reticular formation‚ which consists of a complex system of 100 tiny nuclei occupy the central core of the brain stem from the bottom extremity of the

researching‚ the role of dipstick urinalysis in diagnosing urinary tract infections in older adults residing in health care facilities to phase three by implementing my findings into practice. The first step in this process would be to “educate clinicians and other stakeholders about new practice to be adopted” (Melnyk‚ 2015). In this case evidence shows that dipstick urinalysis alone should not be used to diagnosis urinary tract infections in the elderly. However‚ with symptoms present can be used

“foregut fermenters”‚ or ruminants‚ which have pouches with microbes in the stomach. These microbes consume glucose from cellulose but produce fatty acids that the animal can use for energy. Microbes can also be digested further along the digestive tract as they are also a source of protein. Foregut fermentation‚ or rumination‚ is a slower digestive process‚ but has the advantage of providing more nutrients and wasting less energy. Foregut fermenters include: Cattle Kangaroos and Wallabies Ruminants

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are several important accessory organs that help your body to digest food but do not
