INTRODUCTION:
The purpose of this lap is to see the difference of urine of a healthy person and people with diseases. Like for example a person with untreated diabetes, a person working in a factory with hot and dry air, a person producing little antidiuretic hormone (ADH), or a person having urinary tract infection.
Let’s start with how kidney works. Kidneys are an important part of our body and are bean shaped organ that performs several important roles in the body, which is located below the ribcage. They are essential in the urinary system and their function is to remove extra fluid from the body, make urine, help to make red blood cells, controlling body’s chemical reaction, and even help to control blood pressure. The kidney removes extra wastes and extra water from the blood to form urine. And urine flows from the kidney to the bladder through the ureters.
The wastes comes from the food we eat and from the active muscle. The body uses the food for energy and other things it needs. After the body has taken what it needs, it is send to the kidney through the blood.
Each kidn...
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.
a) Urinalysis with significantly increased amounts of blood (via dipstick and sediment), protein, and leukocytes as well as slightly increased bilirubin and slightly decreased pH;
The kidneys are located in the posterior section of the retroperitoneal cavity and are small, dark red kidney-bean shaped organs in the lower part of the rib cage (Marieb, The Urinary System, 2015). They are undervalued organs considering how essential they are for the body’s ability to maintain homeostasis. The kidneys filter about 120-150 quarts of blood to produce about 1-2 quarts of urine each day (NIH, 2014). Blood initially enters the kidneys through the renal artery. It then flows into the segmental artery before moving into the interlobar artery. From the interlobar artery the filtrate enters the arcuate artery before branching into the cortical radiate artery, which feeds into the afferent arteriole, before passing into the glomerulus where it begins to filter out waste. The filtered waste is then collected by renal tubule. The tubules drain to collecting ducts and all of these components together makes up a small unit called a nephron. Each kidney has over a million nephrons (Marieb, Blood Supply/ Nephrons, 2015). They filter out wastes that run through different body systems via blood; the majority of that waste is nitrogenous wastes, toxins, excess fluids, electrolytes, and drugs. These waste products are eliminated as urine. While waste are removed vital enzymes, hormones, and water are returned
Kidneys play an important role in the unary tract. They are located on each side of the spine, just below the ribcage. Each kidney is connected to the bladder by ureters. The kidneys have many functions, but the most common functions are to clean waste, control chemicals, and regulate fluid in the body which makes up the urine. Urine collects in the kidney before entering the ureters and as time passes more materials are added. When calcium and oxalate or phosphates are combined in the kidney tiny stones are formed called nephrolithiasis, commonly known as kidney stones. These stones can be very painful and “increases risks for diabetes, high blood pressure, and osteoporosis” (Goldfarb, 2009). About ten percent of all people will have kidney stones in their lifetime. Kidney stones are most frequently found in white men over the age of forty, relatives of kidney stone patients, and people who have formerly had kidney stones.
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.

Healthy kidneys clean the blood by filtering out extra water and wastes. They also make hormones that keep your bones strong and blood healthy. When both of your kidneys fail, your body holds fluid. Your blood pressure rises. Harmful wastes build up in your body. Your body doesn't make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys.
All play a role in removing waste from your body. Your kidneys filter waste from your blood and regulate the concentrations of many substances. Tubes called ureters carry urine from your kidneys to the bladder, where it’s store until it exits your body through the urethra.
Hemodialysis and Peritoneal Dialysis To the majority of Americans, dialysis is a confusing process that they will hopefully never have to endure, but for hundreds of thousands of people, it is a daily fact of life. According to US News and World Report, “In the United States, almost 400,000 people undergo dialysis every year.” (Gordon, 2012, para. 4)
Each kidney contains over one million microscopic filtering units called nephrons. Urea, along with salt, water and glucose is extracted from the blood in the kidney by a process called ultrafiltration. Blood that passes the top of the nephron is under high pressure, so fluid is forced through the sieve-like capillaries and into the capsule. This fluid is called the filtrate. It does not contain any blood cells or larger proteins, as they are too big to pass out of the capillaries and into the capsule. Much of what has been filtered out needs to be returned to the blood. They are too precious to lose and so the next process is called selective reabsorption.
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).
The kidneys are bean shaped organs that consist of very thin walled capillaries and large numbers of filtration units called nephrons. They are located both sides of the backbone and are at the same level as the stomach. Each kidney has an inner concave side which is the location of a depression where the renal artery enters and the renal vein and ureters exit the kidneys. In a general term, the kidneys are a filter that removes certain substances from the circulatory system as well as large quantities of water. Some of these substances are reabsorbed into the blood whilst others are transferred to different areas of the body where they will be excreted.
As the kidneys regulate the quantity of fluid which leaves the body, patients who suffer from kidney disease progression, may be not be able to regularize fluid removal from their body. Due to this scenario, their physician or specialist may ask them to reduce their intake of fluid. Lowering daily fluid intake for the renal diet involves: not drinking to socialize or from habit, only having a drink when thirsty, and sucking on a wedge of lemon or chips of ice. It also entails taking measures for monitoring the quantity of fluid that is drunk. This is done by measuring a regularly used glass or cup to measure the quantity of fluid it holds, as well as placing the recommended daily quantity of water into a specific container, and then only taking the fluid that is consumed from this. This insures that the recommended amount is not exceeded (Medical
The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state. In humans and other amniotes most of these substances leave the body as urine and to some degree exhalation, mammals also expel them through sweating.
