How Do Kidneys Work

The embryological development of the kidneys occurs in three successive phases: the pronephros, the mesonephros, and the metanephros. Because of the nature in this development, there are many forms of congenital abnormalities associated with the kidneys. Because of their close developmental association, there is also a complex relationship between the reproductive system and the urinary system.

The job of a kidney is to filter the blood and get rid of waste products; it also balances levels of electrolyte in the body, it controlling blood pressure, and stimulates the production of red blood cells. Your kidneys filter wastes and excess fluids from your blood, which then exit your body

The functions of the renal system, which are performed by the kidneys, are to regulate and maintain the balance of electrolytes and the pH of the fluid that has been processed. It assists in the production of new red blood cells and it also involved in the maintenance of blood pressure.

Its main function is to produce and eliminate urine as a means of maintaining stable concentrations of salt, acids, and other electrolytes as well as to rid the body of toxic metabolic wastes for homeostasis. The kidneys produce the urine while the rest of the urinary system is what carries the urine out of the body. The ureters are a pair of tubes that carry the urine from the kidneys to the bladder by gravity and peristalsis of smooth muscle. The bladder stores the urine until the urine can be passed. When the bladder contracts, the urine enters the urethra, which is the tube that takes the urine from the bladder to the outside.

It represents the part of the kidney that acts like a semipermeable membrane, the nephrons. The nephrons are made of membranous tubules that act analogously to the semipermeable dialysis bag. When blood passes through the tubules, particles in the blood leave the tubule by the process of diffusion.

The renal system also known as the urinary systems purpose is to eliminate wastes from the body, regulate blood pressure, and regulate blood pH.

To explain how diabetes affects the different systems, we need to know how the act normally. The urinary system normal function is to maintain the acid-base balance, conserve fluids, regulate the amount of salts and water in the blood and eliminate liquid waste, known as urea. The urinary system works together with the lungs, skin and intestines to maintain the balance of chemicals and water in the body. The typical adult urinates approximately twenty-seven to sixty-eight fluid once a day of urine. The urinary system includes 2 kidneys (the primary organs in the urinary system), ureters, a bladder and urethra. The kidney is where the filtration occurs, it balances salts and waters. The kidney’s is where nephrons also known as filtering units.

The renal system in the body pertains to the kidneys. The kidneys are the eliminators of waste in the body and collects the ions and elements that that body needs. There are two kidneys, one on each side of the middle to lower back. At

The kidneys play host to a variety of different important functions in our bodies. The kidney’s primary function is the removal of toxins, which is excreted in the form of urine. The second extremely important role of the kidneys is maintaining the body’s acid-base balance. This is balance is maintained by the excretion of fixed acids and the reabsorption of bicarbonate. The hormonal functions of the kidneys include the regulation of blood pressure and the manufacturing of red blood cells.

Kidneys work rapidly throughout the day filtering out the toxic wastes that go through the body. The kidneys filter about 180 liters of blood per day. That is three liters getting filtered 60 times per day. But my question is does having diabetes and hypertension affect the filtration rate in the kidneys?

There are there sections of a kidney and they are the renal cortex, the renal mendulla, the renal pelvis. The blood finds its way to the renal artery, and it splits into or inside arterioles. They go to the Bowman's Capsules of Nephrons, where the waste exits the blood by pressure filtiration4. The Peritubular Capillaries surrond the Nephron so substances can be put in and out of the blood. The renal pelvis takes the urine away from the kidney, it goes inside the uniary bladder which spreads, and sends pulses through the body when it is full. The urine exits the body through the uretha and out of the

Your kidneys are vital organs when it comes to sustaining life, just as other major organs are. They rid you body of any harmful chemicals and materials produced during the normal process of living. Think of them as filters in which your blood passes through. These filters trap the waste and send it out of your body through your urine. This filter then sends the normal contents of your blood back into your bloodstream. An additional task that your kidneys perform is that they also regulate the water and salt content in your body.

The bean-shaped kidneys are retroperitoneal in the posterior abdominal region. They lie in the extra peritoneal connective tissue immediately lateral to the vertebral column (figure 1). In the supine position, the kidneys extend from approximately vertebra T12 superiorly to vertebra L3 inferiorly, with the right kidney somewhat lower than the left because of its relationship with the liver. Although they are similar in size and shape, the left kidney is a longer and more slender organ than the right kidney, and nearer to the midline

It retains substances needed by the body, including water, glucose, amino acids, and ions, such as sodium potassium, calcium, chloride, bicarbonate, and phostphate. Reabsorption of Na+ is especially important because more of them pass the glomerular filter than any other substance except water. Sodium ions are reabsorbed in each portion of the renal tubule by several transport systems. Active transport of Na+ promotes reabsorption of water by osmosis. The loss of water from the filtrate creates a concentration gradient for some substances, such as K+, Cl-, HC03-, and urea, that promotes their reabsorption by passive diffusion. The loop of henle reabsorbs about 30% of the filtered K+, 20% filtered Na+, 35% of filtered Cl-, and 15% of the filtered water. Here reabsorption of water by osmosis is not automatically coupled to reabsorption of filtered solutes. Thus, there can only be independent regulation of both your total body water and the osmotic pressure of body fluids. Two hormones, Aldosterone, and Antidiuretic Hormone or ADH, regulate reabsorption in the final portion of the distal convoluted tubule and collecting ducts. About 90% of the reabsorbed water occurs with the reabsorption of solutes such as sodium and glucose, the rest is regulated by ADH. Whereas tubular reabsorption returns substances from the filtrate to the blood, tubular secretion removed materials that are not needed by the body from the blood and adds them to the filtrate. Secreted substances include potassium, hydrogen, and ammonium ions, as well as certain drugs and wastes. Tubular secretion has two principle effects, rids the body of certain materials, and helps to control blood pH by secreting H+ ions and increasing or decreasing HC03-

There is a pair of kidneys in the human body. They are situated towards the back of the body under the ribs, just at the level of the waist where one on either side of the body. Each kidney is composed of about one million units which are called nephrons and each nephron consists of two parts: a filter which is called the glomerulus and a tubule leading out from the nephron (Cameron 1999). According to Marshall and Bangert (2008) the kidneys have three major functions. Firstly, the kidneys are excretion of waste from plasma in the blood. The second function is that, they maintain of extracellular fluid volume and composition. Lastly, the kidneys have a role in hormone synthesis.
