Nephron

kidney may lose up to 80% of its nephrons before any signs and symptoms may appear. The nephron is the smallest part of the kidney and its job is to filter blood. The loss of nephrons can come from various ways ranging from diabetes, hypertension, urinary tract obstruction, chronic glomerular disease and chronic infection. Diabetes causes loss of nephrons because there is so much glucose in the blood that the glucose get stuck at the filtering site of the nephron causing inflammation and scar…

The outer part is called the renal cortex and the inner part is called the renal medulla. Nephrons are what make the kidneys work. But what are they? They are small independent processing unit that contains a glomerulus, bowman's capsule, capillaries, veins, arteries, the Loop of henle, and a collection duct. As we go along this speech you will figure out what some of the parts are. The nephrons have to filter the blood, but where do they get it from? The constant supply of blood comes from…

How ADH Helps Regulate Water Reabsorption The kidneys are highly specialized organs that regulate water homeostasis in the human body. They are composed of functional units called the nephrons. Within the nephron, the majority of water homeostasis takes place in the collecting duct, as this component is responsible for water excretion (Sands & Layton 2017). The crucial hormone that is released in the collecting duct and is responsible for stimulating water retention is the antidiuretic…

Interrelation between the cardiovascular system and the respiratory system The cardiovascular system and the respiratory system can interrelate to perform a function such as exercise. In order for the body to move our muscles require oxygen. While the body’s muscles are working there is a constant delivery of oxygen to the muscles. The oxygen is taken to the muscles during exercise as a result of the circulatory and respiratory systems working together. The heart, blood and the lungs are the…

capillaries and glomerular capsule. Filtration produces filtrate which is blood minus the cells and proteins. In general, only about 20% of the plasma volume that passes through the glomerulus is filtered. The filtrate then continues through the nephron where it can be reabsorbed or secreted and eventually becoming removed as urine in micturition. Overall, about 180 liters of fluid is filtered by the kidneys every day. Absorption in the kidney is the reclamation of goods such as water and small…

In the beginning a patient may have normal kidney function with little or no symptoms; however, healthy nephrons are being overworked causing them to become larger due to compensation for the diseased nephrons. The overworked nephrons allow for glomerular filtration rate to remain effective until three fourths of function is lost. Overtime as the disease progresses through the various stages it eventually results in…

determined by the Glomerular Filtration Rate [GFR]. The GFR is the rate at which the kidney can relieve the body of toxins or excess fluids and is determined by the quantity of nephrons [the functional filtration units of the kidney]. The GFR is decreased the further progressed the disease becomes due to the destruction of the nephrons (Porth & Porth,…

The renal artery supplies blood to the kidney. The human kidneys receive approximately 25% of the blood pumped. Blood enters the capillaries of the nephron through the afferent arteriole. It then flows through the glomerulus and into the efferent arteriole. The varying sizes of these arterioles help to create the hydrostatic pressure and to maintain consistency of glomerular capillary pressure and renal blood flow within the glomerulus Before returning to the renal vein, blood from the…

The kidneys create and process approximately a liter and a half of urine every day (Port, 2015, p. 599). Inside the kidney, there are more than a million cells that make urine called nephrons. Contained in each nephron is a glomerulus and the job of the glomerulus is to filter the blood. When the glomerulus are attacked the disease that occurs is called glomerulonephritis. The attacks on the glomerulus may come from an infection, the body’s own…

Task 1 Homeostasis is the ability of the body to maintain a constant internal environment within narrow limits. The word homeo means it is unchanging and stasis means it is staying still; it has three main elements that are a sense organ to detect change, a control centre that is usually from the brain or spinal cord and a responding organ to effect a change in conditions. The factors that homeostasis controls in our body are our body temperatures, water content, carbon dioxide levels and our…
