Week 15: The Excretory/Urinary System Study Guide
(NO COPY/PASTING)
List at least 4 functions of the Urinary System. Filter blood to allow toxins, metabolic wastes, and excess ions to leave body through urination Regulate volume and chemical makeup of the blood Maintain proper balance between water and salts, acids and bases Gluconeogenesis during prolonged fasting
What is the role of the renal artery? Transports oxygenated blood from the heart and aorta to the kidneys
What is the function of the nephron? Filtration of blood and the reabsorption of secreted materials
What does the capsule do?It supports and protects the kidney
What is the function of the cortex? It is the main sight for filtration, reabsorption, and secretion
What are renal pyramids? Triangular shaped units in the medulla that house the loops of Henle and collecting ducts of the nephron. This is also the site for the counter-current system that concentrates salt and conserves water and urea
Where is the site of blood filtration? Glomerulus
What does a nephron save for the body? water
Where is the glomerous located? The glomerulus is surrounded by the Bowman’s Capsule
How are kidney stones formed? Crystallization of calcium, magnesium, or uric acid salts that are precipitated down to the renal pelvis
What are the symptoms of cystitis? Inflammation, fever, increased urgency and frequency to urinate
What are the symptoms of Bright’s disease? Back pain, vomiting and fever 13-14) Name two causes for Incontinence. Pregnancy and emotional disorders
15) How does dialysis therapy work? It is a process that removes metabolic waste from the blood
16) What is surrounded by the Bowman’s capsule? Glomerulus
17) What organ is most essential for homeostasis in this system? Kidneys
18) What are the functions of the urinary system? Filtration, Secretion, Reabsorption ,Activation of Vitamin D
19) What are the components of the nephron? Renal
