The kidneys are retroperitonel, which means they are? | Behind the peritonel. |
The kidneys are cushioned by? | Fat |
The kidneys are held in place by by the | renal fascia |
The function of the renal fascia is to? | Hold the kidney in place. |
The renal fascia is made of what? | fiborous connective tissue. |
A ureter extends from what to what? | Kidney to the urinary bladder |
The urethra extends from what to what? | urinary bladder to the exterior |
The ureters takes urine from the kidney to to the what? | urinary bladder |
The what takes urine from the bladder to the exterior? | urethra |
The male urethra is enclosed by the prostate gland and the what? | penis |
The outer layer of the kidney tissue is called what? | renal cortex |
The inner layer of the kidney is called? | Renal medulla |
Renal pyramids and renal medulla are the same thing? | True |
The cavity on the medial side is called the? | renal pelvis |
What is located in the renal medulla? | loops of henle |
In calyces are part of the are part of the? | renal pelvis |
In the kidney the renal pelvis has a funnel shaped extension called? | calyces |
The renal pelvis empties urine into the? | ureter |
Urine is formed from? | blood plasma |
Two major parts of a nephron are? | renal corpuscle, renal tuble |
A renal corpuscle consist of? | glomerulus and Bowman's capsule |
a glomerulus is surrounded by | Bowmans Capsule |
a glomerulus is a network of? | capillaries |
A bowmans capsules has how many layers? | Two |
The Bowmans layer that is permeable layer is the? | inner |
The energy for renal filtration is provided by? | blood pressure |
What does not become part of the renal filtrate in the process of glomerular filtration? | blood cells and large proteins |
What may become part of filtration in the glomerular filtration? | water, waste products, and small proteins |
The processes of reabsorption and secretion take place in the what portion of the nephron? | renal tuble |
The renal tubles are surrounded by the? | peritubular capillaries |
What is reabsorbed by the process of active transport? | glucose, amino acids, vitamins,and positive ions, |
Water is reabsorbed by the process of? | osmosis |
Negative ions are reabsorbed by the process of? | passive transports |
Small proteins are reabsorbed by the process of? | pinocytosis |
In the proximal convoluted tuble, the surface area of the cells is increased by the presence of? | microvilli |
The renal artery is a branch of the? | abdominal aorta |
The renal vein carried blood to the? | inferior vena cava |
The hormone that directly increases the reabsorption of water is? | ADH |
The hormone that increases the excretion of sodium ions in water is? | ANP |
More water will excreted in the urine if ADH secretion decreases or increases? | Decreases |
The purpose of the renin-angiotensn mechanism is to? | raise blood pressure |
The retnal tubles are surrounded by the? | peritublar capillaries |
In the proximal conoluted tubule, the surface area of the cells is increased by the? | Microvilli |
The maximum amount of glucose that can be reabsorbed by the kidney tubules is called the? | threshold level |
The process of tubular secretion may include the nitrogenous waste product is? | filtrate |
The renal artery is a branch of the? | abdominal aorta |
The renal vein carried blood to the? | inferior vena cava |
The hormone that directly increases the reabsorption of water is? | ADH |
The effect ADH is to? | increase the reabsortion of water. |
The hormone that increases the excretion of sodium ions and water is? | aldosterone |

The hormone that increases the reabsorption of calcium ions is? | PTH |
More water will be excreted in urine if what is decreased? | ADH secretion |
The kidneys respond to increased acidity of the blood by excreting? | hydrogen ions |
The kidneys respond to increased alkalinity of the blood by retaining? | hydrogen ions |
The part of the urinary bladder that expels urine is the | detrusor muscel |
The purpose of the rein-angiotensin mechanism is to? | raise blood pressure |
The internal urethral sphincter is usually contracted to prevent what? | outflow of urine |
The part of the CNS that is directly involved in the urination reflex is the? | spinal cord |
The stimulus for the urination reflex is stretching of the? | detrusor muscle |
As part of the urination reflex, the internal urethral does what? | Relaxes |
Voluntary control of the urination reflex is provided by the? | external urethral sphincter |
Normal urinary output per 24 hour is? | 1 to 2 liters |
The normal pH range of urine is? | 4.6 to 8.0 |
