Urinary System Essay

There is a delay in the onset of diuresis after loading in the control subject as it takes time for the water to be filtered in the body. Water is absorbed from the gut into the extracellular fluid. Osmoreceptors from the posterior pituitary detect the water through cell stretch and initiate responses that control ADH secretion (Widmaier et al., 2014). Fluids are filtered through the kidneys and the excess water is transported to the bladder where it will then be excreted.

The amino acids that are not immediately required are broken down in the liver to make urea; this urea is carried in the bloodstream to the kidneys for elimination of waste.

Consequently, the efferent arteriole, which filters blood away from the glomerulus, is tinier in diameter than the afferent arteriole, which carries blood into each glomerulus. This puts blood under high pressure in the glomerulus; thus it forces tiny molecules and liquid out of the capillary and into the Bowman’s capsule. Soon afterwards, the tiny and liquid molecules cross the epithelium of the Bowman’s capsule, the basement membrane and capillary wall in order to get into the Bowman’s capsule and to arrive in the nephron tubules. The consequence of this is that the filtrate (the tiny and liquid molecules) pass along the remainder of the nephron and helpful substances are reabsorbed along the route. Last of all, “the filtrate flows through the collecting duct and passes out of the kidney along the ureter” as mentioned by (Parson’s, R: p128).

C. What is the function of the ureter? How does the structure support this function?

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.

Brenner (2007) explained that the primary function of the kidneys is to excrete waste products resulting from metabolism by filtering them out of the bloodstream into urine. The kidneys also have many homeostatic functions such as maintaining acid-base homeostasis and electrolyte concentrations, and regulating plasma osmolarity and blood pressure (Brenner, 2007). The kidneys secret and interact with a variety of hormones such as

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

Marissa, a newborn with a cleft lip and palate, is the third child of Juan and Maria. Both Juan and Maria are “visually alarmed” at Marissa’s appearance; however, Juan is more distant and reserved. Maria is very concerned with Marissa’s wellbeing and future and seems to take blame for Marissa’s physical condition.

Most urinary tract infections are primarily caused by bacteria that live in the bowel region of the body. The bacterium Escherichia coli, commonly referred to as “E. coli”, causes most UTIs. The urinary tract has several systems to prevent infection. The points where the ureters attach to the bladder act as only one way valves to prevent urine from moving back up toward the kidneys. Urination is intended to wash microbes and any infectious bacteria out of the body. In males, the prostate gland produces secretions that slow down bacterial growth in the urinary tract. In both woman and men, immune defenses try to prevent infections, but despite these safety procedures put in place by the body, infections still do occur in some individuals.

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 ureter helps collects filtrate and urine this is from the renal pelvis the next step for it will to be taken into the bladder; the ureter works at all times in health animals/ people (Gondar Design Biology, 2015). Urine usually flows by gravity but mainly the flow is caused by waves of contractions in which normally happy several times per minute (InnerBody, 2015).

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.

How many of us really think about our ability to urinate, I know I never did, but for my Uncle and Cousin, they could only wish to do what comes so naturally to us. When you have kidney disease and suffer Renal failure, which is what both of my relative's had, the kidneys are unable to remove those wastes through urinating. When the kidneys no longer perform these functions adequately, wastes and excess fluid build up in the blood. Some of the warning signs of kidney disease are as follows:

To understand what renal failure is, it is important to know how the kidneys work and what the main functions are. The body has two kidneys on either side of the spine and the kidneys work to remove toxic waste and excess water by producing urine. The kidneys also help with controlling blood pressure and produce erythropoietin as well as aiding in keeping bones strong by producing calcetrol hormones. When the kidneys are unable to perform these functions it causes the kidneys to fail.
