Human Biology Digestive and Urinary System Essay

Abs package The human trunk needs to master(prenominal)tain proper homeostasis to survive. There be several diametrical organ musical arrangements in the human torso. Two of those systems are the digestive system and the urinary system. some(prenominal) systems remove down from the body but in an entirely different way. They also obligate homeostasis within our business stream. Both systems are critical for survival. This paper will describe how each of those systems on the job(p) on its own and also how they sound together to carry homeostasis for the body.How the urinary and Digestive Systems Work Together to Maintain Homeostasis The digestive system kit and caboodle to bring foods into the body with a series of hollow organs working together extending from the mouth to the anus. These hollow organs are the mouth, pharynx, esophagus, stomach, sm all(prenominal) intestine, gargantuan intestine, rectum, and anus. These hollow organs make up the gastrointestinal (GI) brochure. 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 is the mechanical process and movement of food playn into the body. Chewing breaks food into smaller pieces, and ii types of movement mix the contents of the lumen and propel it forward. The lumen is the inwardly lining of the GI tract. Secretion is the fluid, digestive enzymes, acid, alkali, bile, and mucus that are secreted into the GI tract at various places.Digestion is where the contents of the lumen are scummy down mechanically and chemically into smaller and smaller particles, culminating in nutrient molecules. Absorption is what happens when the nutrient molecules pass across the GI tract and into the gillyflower line. liquidation is all of the undigested material is eliminated from the body through the a nus. (Johnson) These GI tract and the four accessory organs of the digestive tract work together to complete the five processes in order to bring nutrients into the body, and eliminate waste. The immense intestine assumes nutrients and eliminates waste.The small intestine absorbs nutrients and pee. The water and nutrients absorbed from the intestines go into the origination stream . (Johnson) The urinary system consists of the kidneys, ureters, bladder, and urethra. The ureters, bladder, and urethra transport and store urine until it is eliminated from the body. The kidneys get to urine. Urine is the nitrogenous waste removed from the blood stream. It is essential to the body to remove this waste in order to maintain homeostasis. (Johnson) The kidneys perform all of the main functions in the urinary system.They regulate water levels in the body. When you take in water every daytime it is up to the kidneys to excrete the exorbitance water or to conserve as much as possible. Th e kidneys bedevil a great capacity to adjust water excretion as necessary. Normally with a minimum of a half liter per day to one liter per hour. (Johnson) The kidneys also regulate the nitrogenous waste and different solutes in our blood. One waste that is toxic to our cells is ammonia. Ammonia is detoxified quickly by the liver by being combined with carbon dioxide to create urea.Urea is the main waste product in urine. Sodium and chloride are some(prenominal) correct by the kidneys as well. Sodium and chloride are both very weighty to determine the volume of extracellular fluids, like blood. This directly affects blood closet. (Johnson) opposite substances that the kidneys regulate are potassium, calcium, hydrogen, and creatinine. It is up to the kidneys to maintain homeostasis with each of these substances. Creatinine is a waste product that is produced during metabolism. This is one of the wastes that give urine a yellow color. Johnson) The digestive system removes nutri ents and water from the food that we eat and drink and transports it to our blood stream. either solid wastes that are unable to be digested are then eliminated from the GI tract. Our urinary system then removes any of the unwanted and unneeded substances and wastes from the blood stream and excretes them in urine. This is how homeostasis is maintained in our body with waste, so that in that respect is no toxic build up in our body from sure substances. Homeostasis is critical to be maintained within the body for survival.Homeostasis is the bodys ability to maintain relatively stable internal conditions even though the outside world is continuously changing. (Marieb) All living things must maintain an internal environment harmonious with life, and the range of chemical and physical conditions compatible with life is very narrow. (Johnson) In order for the digestive and urinary systems to work together to maintain homeostasis both systems must be functioning properly. start we c onsume food and water. Then our digestive system absorbs the nutrients and water into our blood stream.Once the nutrients and water is in our blood stream our urinary system the filters the blood and removes any additional waste and maintains the proper homeostasis with the nutrients we consume. If our digestive system is not functioning properly then we are not able to absorb the proper nutrients and fluids in order to allow our kidneys to filter our blood and maintain homeostasis. If our urinary system is not functioning properly than the nutrients and fluids we consume abide cause a buildup in our blood stream of toxic wastes and fluids and go for off homeostasis.Either way it would be detrimental to our body for this to happen. Our blood pressure would be affected severely and this would cause issues with not only our cardiovascular system but also our respiratory system. It is critical to keep both systems healthy to ensure that our bodys have the proper water and nutrients t o survive and that all waste is secreted from our systems.
