Excretory System The excretory system is a biological system found in the human body. This particular system’s vocation is to remove excess waste that was contrived by metabolism, this system thus maintains Homeostasis. Now, before we advance, we should elucidate on what Homeostasis. Homeostasis is essentially the body attempting to maintain equilibrium. The excretory system attempts this by removing waste to equipoise to the desired level of consistency. Due to the fact that some of the organs may act independently, this organ system‘s functions are only vaguely related to one another and thus this organ system is not often observed in formal use. Components: The excretory system is constituted by several organs, but these organs do not necessarily all act in conjunction to one another as we previously stated. These organs are similar inasmuch as they serve the composite function of removing waste. Here are the organs in the Excretory System and their purpose. Skin The skin exhausts excess salt, water and urea from blood in the form of sweat on to its surface. Besides the removal of waste, the skin is also pertinent to homeostasis, as sweat helps maintain temperature. Lungs Lungs are viewed as part of the excretory system because by-products of respiration (water, carbon dioxide) are disposed of through the lungs. Urinary System: Note: When presenting, explain this with concision, as in briefly intimated on The urinary system is just one component of the Excretory system, and serves the purpose of filtering wastes from blood and ejecting it through the urethra. Kidneys There are two kidneys in the human body and these kidneys are around 140-160 grams in weight and approaching the size of a fist. Its shape is an... ... middle of paper ... ... the body. The urethra is found in the genitals of a person. It also serves a function in the reproductive system, where it also ejects seminal fluid or semen. Large Intestine: The large intestine is the last portion of the digestive system, but also a component of the excretory system. It absorbs water remaining from indigestible wastes and also excretes the remaining waste as feces through the anus. This expulsion process is known as defecation. The Excretory System is clearly an essential body system, due to it removing various toxins from the body. Clearly, the absence of such a crucial system would portend for a very inauspicious fate, due to the fact that there is no way to expel fecal matter, nor the presence clean blood. Besides this, the Excretory system maintains a homeostatic function that is also important for the human bodies survival.
As for the kidney’s, they consist of a renal cortex with arcuate vessels surrounds the renal medulla of the kidney. The renal papilla at the end of the renal medulla connects to the renal pelvis. Finally, a ureter descends form the kidney to the urinary bladder in both the mink and human.
Through performing dissections, the interrelationships between functioning systems can be further understood. In the dissection of the fetal pig, three interrelationships can be defined: cardiovascular and respiratory, digestive and excretory, and digestive and cardiovascular.
In our body’s we have thousands upon thousands of cells that work together to maintain the whole structure. Although cells accomplish different roles, they all are comparable in their metabolic conditions. Preserving a continuous inner environment with what the cells require to survive like sugar, minerals, oxygen and waste removal is essential for the cells and host well-being. The diverse process that the body controls its inner environment are referred to as homeostasis. Homeostasis refers to maintaining a stable environment in reaction to environmental changes. The body’s inner environment requires constant observation to maintain a stable inner environment this way if conditions occur they can be adjusted. Homeostatic regulation is the adjustment of systems in the body. “Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector.” (Wikibooks, para. 2)
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no life.
Homeostasis involves the whole body, but certain organs have larger roles in maintaining the balance. The liver and pancreas maintain suitable glucose levels in the blood, with kidneys removing metabolic waste products and maintaining suitable salt and water levels within the blood. The skin and liver help maintain body temperature with lungs controlling oxygen and carbon dioxide levels in the blood and the blood itself transporting the nutrients and waste products around the body.
The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though.
The digestive system is a group of organs that works together to convert food into energy and basic nutrients that will feed the entire body. The digestive system breaks down food so nutrients can be absorbed by the body. The digestive system has three main functions. First, it ingests food then breaks it down so nutrients can be absorbed and it also eliminates what cannot be digested.
Lets begin by discussing the big picture view of the urinary system. It is comprised by the kidneys, ureter, bladder, and the urethra. Referring to the anatomical position the right kidney is lower than the left kidney due to the liver being large. In a transverse cut and view from above one can see that the digestive organs are in a separate cavity from the urinary system. The peritoneal cavity houses the digestive organs and it houses serous membrane which secretes a small amount of fluid in the cavity that lubricates organs so that they experience very little friction as they move about inside of the body. The kidneys are in the retroperitoneal cavity, literally that means behind the peritoneal cavity. Unlike the digestive organs the kidneys are not allowed to move much when the body moves. They are held in place by perirenal fat, this fat firmly holds them in place. If someone gets to abnormally thin the kidneys can slip causing the ureter to get pinched.
The urinary system is composed of the kidneys, the ureters, the urinary bladder, and the urethra ("Urinary System", n.d.). These organs and tubes shape what is called the urinary tract, the body’s drainage system for removing urine from the kidneys, storing the urine, and then expelling it during urination ("Urinary System", n.d.). The first part of the urinary system is the kidneys. The kidneys are a pair of bean-shaped organs located in the upper abdominal cavity against the back muscles ("Urinary System", n.d.). The kidneys are responsible for filtering the blood to remove waste and chemicals to produce urine ("Urinary System", n.d.). Blood is carried through the renal arteries to the kidneys where they are filtered by nephrons - tiny filtering units in both kidneys that remove harmful substances and waste from the blood (Durani, 2015). The toxins and waste sifted by these nephrons are blended with water to produce urine (Durani, 2015). On average, the kidneys will filter 120 to 150 quarts of blood a day to produce about 1 to 2 quarts of urine ("The Urinary Tract & How It Works", 2014). The next
The waste of my "ham" sandwich keeps going. The haustra removes any excess water that was not absorbed in my small intestine. It doesn’t have to do much work, because there is hardly any area for absorption. The waste then travels down my sigmoid colon to my rectum. There the waste, now called fecal matter (A.K.A. feces) is stored until I have enough to defecate through my anal sphincter.
The filtered blood leaves the kidney along the renal veins. The filtered waste products are excreted by the kidney as urine. A narrow tube called the ureter carries urine from the kidney to the bladder. From there the urine is excreted through a single tube, called the urethra. Kidney structure: If you cut a section through the kidney, three areas can be seen:
The urinary system helps regulate a woman’s pH balance. Although, the urinary system is beneficial it also can also be very open to infections, blockages and injuries. Inside the body, the kidney’s helps make the urine by filtering wastes from the body. The urinary system works with many parts throughout the body such as the lungs, the skins and the intestines (Urinary system 2017).
...urpose is to clean the urethra of harmful bacteria and other substances prior to ejaculation. The penis, not composed of muscle or bone, is the next step for the sperm. It’s three main purposes are to transport urine, transport semen, and to provide sensation. Inside the penis is the urethra. The urethra’s functions are to carry urine from the bladder to outside the body, and to ejaculate semen during sexual intercourse. The tip of the penis is called the scrotum, and it’s three main functions are to act as a thermometer for the testicles, protect and hold the testicles, and to provide various sensations.
The digestive system is very responsible for taking the whole food that people eat and turns them into energy and nutrients to allow the body to function, grow, and fix itself. The six primary processes of this system are ingestion of food, secretion of fluids and digestive enzymes, mixing and movement of food and waste throughout the body, digestion of food into small pieces, absorbing the nutrients, and the elimination of wastes. Ingestion is the first function of the digestive system, which is also known as the intake of food. The mouth is the reasoning for this process because through the mouth is the way food enters the body. The stomach and the mouth store food until your stomach is ready to digest the food that was just eaten. The reason why people can only eat a few times a day is because your body can only allow a certain amount of food depending on your body weight and type, and it cannot ingest more food than it can process at one time. The next step in Secretion, this happens in the course of the day. The digestive system secretes about 7 liters of fluid daily, but these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile...
The excretory system, which includes the rectum and anus helps the digestive system by getting rid of waste and the digestive system helps the excretory system by breaking down food to be eliminated from the body. Wow! The human body wouldn’t be able to work without one or the other. Anyways, I hope you enjoyed reading my journey throughout the human digestive system. I hope to write again from where my next journey from here will begin- perhaps it will be in the ocean or along Sydney Water pipes. Until next
