Biology U5L12 Urinary System

Front 1

Identify the organs that make up the urinary system and interpret the function of each.

Back 1

kidneys: filter blood to remove waste; ureters: carry urine from kidneys to bladder; urinary bladder: stores urine; When the bladder contracts, urine flows out of the body through the urethra.

Front 2

What is the function of a nephron in the kidney? Describe what happens in the glomerulus, Bowman's capsule, and U-shaped tubule.

Back 2

to filter wastes from the blood plasma; In glomerulus, water, glucose, vitamins, amino acids, protein waste products, salts and ions pass into Bowman’s capsule; in U-shaped tubule, most of the ions and water and all of the glucose and amino acids are reabsorbed into the bloodstream.

Front 3

Identify the major components of urine, and explain why it is considered a waste fluid.

Back 3

urea, water, nitrogenous wastes, excess salt; contains toxic products from the metabolic breakdown of proteins

Front 4

What is the kidney's role in maintaining homeostasis in the body?

Back 4

removes urinary waste; maintains blood pH, sodium levels, and osmotic balance

Front 5

During a routine physical, a urine test indicates the presence of proteins in the patient's urine. Explain what this could indicate about the patient's health.

Back 5

High blood pressure could force proteins into Bowman’s capsule or the patient could have a kidney infection.

Front 6

Trace the sequence of urinary waste from a cell to the outside of the body.

Back 6

cell to blood to kidney to nephron to ureter to urinary bladder to urethra

Front 7

remove wastes, control sodium, and regulates blood pH
