Intro to Chronic Kidney Disease
Delve into the abdomen to see chronic kidney disease (CKD) from an inside point of view. View how exactly these amazing, multitasking organs filter toxins out of the blood while maintaining your blood pressure and regulating red blood cell production. Watch as cleansed blood flows out of the kidneys, and zoom in closer still to see the tiny and incredibly complex network of filtering capillaries in the kidneys’ nephrons. Witness the deterioration of kidney tissue over time into kidney failure, and see how protein and other substances leak out of diseased capillaries. Dialysis is necessary in advanced kidney disease: learn how lifestyle changes can slow the progression of CKD.
Voyage into your body to see an amazing creation you're born with: the perfect cardiovascular system. A lifetime of poor health habits can destroy that system and lead to major medical problems and a shortened lifespan, but it doesn't have to be that way. You have the power to keep your body and mind healthy, strong, and alive. See how you can live longer and live better.
What are the Complications of Hypertension?
Left untreated, the force of high blood pressure battering the walls of your blood vessels can take its toll and lead to serious complications, like heart disease, stroke, kidney disease and vision loss.
Urinary Tract Infection
Our kidneys are remarkable filters. Each day, they filter about 200 quarts of blood to extract about 2 quarts of wastes, which is then eliminated as urine (2 ureters connect the kidneys to the bladder, which stores urine, until it is passed through the urethra). Urine does not normally contain bacteria, but infections can occur, particularly if there are obstructions of the urethra; according to the American Urological Association foundation, urinary tract infections result in more than 7 million visits to doctor's offices each year (about 5% of all visits to primary care physicians).
The body's fluid balance is kept within a narrow range by the kidneys, which constantly monitor and adjust blood levels of electrolytes (sodium, calcium, potassium, bicarbonate, and chloride) as well as blood proteins such as albumin. If the body is unable to self-regulate, however, treatment may involve dietary changes (lower salt intake or increased fluid intake, for example), diuretics or treatment of the underlying disease causing the fluid imbalance.
Insulin Receptor and Glucose Pump of Diabetic Person
Our bodies and brains run on glucose, a simple sugar produced by the digestion of carbohydrates. The body's ability to use glucose depends on the hormone insulin, produced by the pancreas. Blood sugar levels naturally rise after meals, but insulin keeps these levels within a narrow range. In diabetes, however, the body loses its ability to respond to insulin or the pancreas loses its ability to produce insulin. Diabetics must maintain normal blood sugar levels through dietary control and insulin injection. Diabetes current affects 25 million Americans; complications include kidney failure, blindness, and amputation.
Bladder Cross-section, Full and Empty
Part of the urinary system, the bladder is a muscular sac into which urine flows from the kidneys through the ureters. As the bladder fills with fluid, nerve fibers in the walls detect stretching and signal the need to void.
