Urinary systems *
| Question | Answer |
|---|---|
| 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) |
