Urinary systems *

QuestionAnswer
These organs excrete metabolic wastes: Liver, Kidney, Digestive system, Skin, and Lungs
What are principle metabolic wastes? Water, Carbon dioxide, and Nitrogenous wastes (Urea +Uric acid) and Creatinine.
What are the two main regions of a Nephron? Renal Corpuscle & Renal Tubule
What is the sequence of structures through which filtrate flows from Bowman's capsule to the collecting duct? Bowman's capsule>Proximal convoluted tubule>Loop of Henle>Distal convoluted tubule>collecting duct
The Urinary system helps to regulate what? The volume and composition of body fluid.
The main organs of the Urinary system are these? Kidneys, Ureters, Urinary bladder, and Urethra.
Kidneys excrete ? Urea/Uric acid/Urine
Digestive system excretes? Feces
Skin excretes? Sweat
Lungs excrete? Exhaled air containing water vapor & carbon dioxide.
Urine is conducted from the renal pelvis to the urinary bladder by the ? Ureter
Urine in a major calyx next passes into the renal ? Pelvis
The outer portion of the Kidney is the renal __?__ , and the inner portion is the renal ____?____. Cortex & Medulla
The renal corpuscle consists of a cluster of capillaries, the ______ surrounded by _____ ______. Glomerulus surrounded by Bowman's capsule.
Blood flows into capillaries of the glomerulus through the ______ arteriole. Afferent
From the proximal convoluted tubule, filtrate flows into the _____ _____ _____? (U-shaped section of the convoluted tubule.) Loop of Henle
Some plasma leaves the glomerular capillaries and passes into ______ ______? Bowman's capsule
The process of returning most of the filtrate to the blood is known as ? Tubular reabsorption
The adjusted filtrate is called ? Urine
Helps to prevent dehydration by inhibiting urine output via increased permeability of the distal convoluted tubules and collecting ducts of the Kidneys. ADH
Temporary storage sac for urine between ureters and the urethra? Urinary bladder
During tubular secretion : Hydrogen ions and certain other ions are discharged from the peritubular capillaries into the filtrate.
Most body fluid is located in the ____? intracellular compartment
Compounds such as salts that form ions in solution are called ? Electrolytes
Increases sodium reabsorption by the Kidney tubules: Aldosterone
The hormone (ANP) Atrial natriuretic peptide : Decreases blood pressure.
Resist changes in pH when acid an acid or base is added to a fluid: Chemical buffers
Occurs when the hydrogen ion concentration is too high: Acidosis
The branch of medicine related to male/female urinary systems. Urology
When fluid output is greater than fluid input in the body. (usually 2,500 ml) Dehydration
A failure to completely or normally void urine possibly due to an obstruction in the urethra Retention
The lack of voluntary control over micturition(urination.) Incontinence
Chemicals such as coffee, tea, and alcohol that increase urine volume by inhibiting reabsorption of water. Diuretics
Painful urination (always report to Dr.) Dysuria
The accumulation of excessive fluid in the tissue. Edema
An excessively high level of Uric acid in the blood. Gout
Composes 60-90% of all Nitrogenous material in urine. Urea
Urea toxic levels of Urea in the blood resulting from severe malfunction of the kidneys. Uremia
The process of eliminating urine from the Urinary bladder. Micturition (urination)
The OUTERMOST area of the interior of the Kidney. Renal Cortex
The INNERMOST area of the Kidney. Renal Medulla
Microscopic unit of filtration within the kidneys. Filter the blood of nutrients and wastes. Nephron
An inorganic (nonliving, noncarbon containing) element that can conduct electricity such as Sodium, Potassium, and Chlorine. Electrolyte
A ball of capillaries encased by the Bowman's capsule that allows wastes, nutrients, and water to pass through the capillary walls. Glomerulus
A strong protective Kidney covering. Renal capsule
Massage is not contraindicated for someone who has a history of these calculi so long as they are not experiencing any symptoms. Kidney stones
The primary function of the Urinary system is to keep the body in a state of ______? Homeostasis
An element such as Na+, K+, or Cl-. Electrolyte
_____ is composed of 96% water, 2.5% Nitrogenous wastes, 1.5% salts and trace substances Urine
Urine is produced by the filtering wastes and excess water from the _____.? Blood
Filtrate moves from the Proximal convoluted tubule, through the Loop of Henle, to the Distal convoluted tubule, and into the ______ _____ before entering the ureter as urine. Collecting duct
Urine and its filtered substances. Filtrate
Waste removal structures of the body include the _____, _______, and ________ ________. Skin, Lungs, and Gastrointestinal tract.
Composed of the pelvis, major and minor calyces, pyramids, papilla at the tip of the pyramids, and nephrons. Renal pyramids
Made up of the renal corpuscle and renal tubule, it filters the blood to produce urine. Nephron
_____ ______ happens via the Kidneys, evaporation of perspiration, exhalation, and the GI tract at the rate of about 2,500 Ml per day. Fluid output
These two structures are located retroperineal just below the Diaphragm at the level of T12 and L3 and are protected by the lower 11th and 12th ribs. Kidneys
Fluid _____ should = fluid output. input
Urination is a _______ nervous system (rest & digest) response. Parasympathetic
The Urinary bladder can hold about ___ pints of urine. 1.5
The are more than a ______ nephrons in the Kidney. Million
Stretch receptors control your micturition(urination) _______. Reflex
________ eliminate H2O, produce Vit D, and regulate electrolyte and fluid balance. Kidneys
The ______ arteriole leads blood AWAY from the glomerulus. Efferent
Efferent = ________ Afferent = _______ Away, Toward(Too)
