What are the four functions of the urinary system? | Regulation of ion levels in the blood, regulation of blood volume and blood pressure, regulation of blood pH, and production of hormones. |
What is the difference in location of the renal cortex and the renal medulla? | The renal cortex is the outer region of the kidney and the renal medulla is the inner region of the kidney. |
Where is the glomerulus located, what is its function? | They are located on the afferent arterioles and ultimately allow the waste to drain into the renal vein. |
Where is the nephron located, what is its function? | The nephron is located in the renal cortex of the kidney, it filters plasma and allows glomerular filtrate to pass through. |
What are the functions of the afferent and the efferent tubules? | |
What is the function of the Bowman's Capsule? | It filters the urine then passes it into the renal tubule. |
What are the three functions of the nephron? | Glomerular filtration, tubular reabsorption, and tubular secretion. |
What is glomerular filtrate? | The first step in urine production, filters the urine. |
What is the funtion of the proximal convoluted tubule? | Reabsorbes the things that were filitered into the blood and secretes the other things into the urine. |
What is the funtion of the loop of Henle? | Create a concentration gradient in the medulla of the kidney. |
What is the funtion of the distal convolute tubule? | Reabsortions of some salts while it continues to retain water. |
What is the common volume, color,and turbidity of urine? | Volume is one to two liters, color is a yellow or amber color, and is transperent when freshly voided, but becomes turbid (cloudy) after a while. |
Where are the ureters located, what is their funtion? | They are located at the top of the urinary bladder but lead into the bladder, they transport urine from the kidneys to the urinary bladder. |

What is oliguria? | A daily urine output of 50ml and 250ml. |
What is glimerular filtration rate? | The amout of filtrate that forms in both kidneys every minute. |
What is tubular secretion? | The trasnfer of materials from the blood throught tubule cells and into tubular fluid. |
What is glucosuria? | When glucose remains in the urine. |
What is polyuria? | The excessive secretion of urine. |
What is ADH? | Antidiuretic hormone, the major hormone that regulates water reabsorption. |
What is ANP? | Atrial natriuretic peptide, one of the most imporant hormal regulators of ion reabsorption and secretion. |
What is urinalysis? | An analysis of the volume and physical, chemical, and microscopic properties of urine. |
What is the sphincter? | An opening to the urethra. |
What is micturation? | Urination,expelling urine from the body. |
What is incontinence? | The inability to prevent urination. |
