Anatomy and physiology of the renal and Urologic systems

Which is the function of the collecting duct?

Acts as a drainage system The collecting duct is a network of small tubes that acts as a drainage system.

What is the pathway, in order, of urine production by the kidneys?

Blood enters semipermeable glomerulus Glomerular filtrate is collected in the Bowman's capsule Glomerular filtrate moves to the proximal convoluted tubule Urine travels to the loop of Henle to distal tubule Urine travels to the collecting duct Blood enters the semipermeable glomerulus. The Bowman's capsule collects the glomerular filtrate. This glomerular filtrate then moves to the proximal convoluted tubule where reabsorption of nutrients and electrolytes occur. Then urine travels through the loop of Henle where reabsorption of sodium, chloride, and water occur as the filtrate becomes concentrated. Urine then travels to the collecting duct.

Which structures are considered the layers of the kidney?

Cortex Medulla Fibrous capsule The medulla is the inner layer of the kidney. The fibrous capsule covers the outside of the kidneys and protects them. The fibrous capsule is the outer-most layer of the kidney.

Which is glomerular filtrate?

Filtered blood Glomerular filtrate is the filtered liquid portion of blood that passes from the Bowman's capsule into the proximal convoluted tubule.

Which is the correct order of urine flow through the structures of the kidney?

Medullary pyramids Minor calyces Major calyces Renal pelvis Ureter Urine passes from the medullary pyramids via collecting ducts of the nephron to the minor calyx. Minor calyces widen and merge to form major calyces. Major calyces combine to form the renal pelvis. The renal pelvis acts as a funnel for urine flowing to the ureter.

The adult urinary bladder holds up to __ mL of urine.

The adult urinary bladder holds 600 to 1,000 mL of urine.

Which structures comprise the renal tubular system?

The loop of Henle is located in the medulla and is part of the renal tubular system. The distal convoluted tubule is located in the kidney's cortex and is part of the renal tubular system. The proximal convoluted tubule is located in the kidney's cortex and is part of the renal tubular system.

Which substances does the proximal tube reabsorb?

Water Glucose Bicarbonate
