Name the functions of the renal system. (A WET BED) - ANSWER - Acid-base balance Water balance Electrolyte balance Toxin removal Blood Pressure control Erythropoietin making D vitamin metabolism
What is the functional unit of the renal system? - ANSWER - The Nephron
Glomerular Filtration Reabsorption Secretion
What is the glomerulus and what is its function? - ANSWER - It is at the beginning of the nephron, it's a network of capillaries that performs the first step of filtering the blood.
Explain Glomerular Filtration Rate and why is it significant to renal function? - ANSWER - Measures how well the kidneys are filtering blood. Determines if the kidneys are working correctly or if they are failing How does CKD affect other body systems? - ANSWER - Can cause mulit-system organ failure due to impaired filtration and buildup of toxins·

pg. 2 What is the link between erythropoietin and kidney failure/injury? - ANSWER - When the kidneys are damaged, they often do not make enough EPO, resulting in the bone marrow producing too few red blood cells. This leads to a decrease in the amount of oxygen delivered to organs and tissues
Which diagnostic tests are used to determine renal function? - ANSWER - Urinalysis Glomerular filtration rate Blood tests serum creatinine blood urea nitrogen Cystoscopy Ultrasonography Radiologic
Explain the role of the tubules within the nephron. - ANSWER - As the filtrate flows through the tubule,
the concentration of water and electrolytes in the filtrate changes due to:
O Reabsorption of water and solutes by tubular cells into the peritubular capillary blood
O Secretion from the blood into the tubular lumen
Define micturition reflex - ANSWER - a reflex pathway that causes bladder contraction during urination
Function of Body Fluids - ANSWER - - Transport gases, nutrients, and wastes
- Help generate the electrical activity needed to power body functions
- Take part in the transforming of food into energy
- Maintain the overall function of the body
