Urinary System

Question 1

Urinary system consists of: (in order of how urine is expelled)

Answer 1

2 kidneys
2 ureters
Urinary bladder
Urethra

Question 2

Kidney function:

Answer 2

Filters blood

Question 3

Ureter function:

Answer 3

Tubes that transport urine to the bladder, where urine is stored before urination through the urethra to the outside

Question 4

Nephrons:

Answer 4

Filters blood by removing waste material and return the substances we need in our blood

Question 5

Filtration process of blood in the kidneys:

Answer 5

• Occurs through the glomerulus in Bowman’s capsule of the nephron under the force of blood pressure
• Components needed by the body such as water, glucose, and ions leave the nephron by diffusion and reenter the blood
• Water is reabsorbed at the tubules of the nephron

Question 6

Glomerulus:

Answer 6

Filters blood via capillaries by removing proteins

Question 7

Renal corpuscle consists of:

Answer 7

Glomerulus and bowman’s capsule

Question 8

Bowman’s capsule:

Answer 8

Entrance to proximal convoluted tubule, covers glomerulus

Question 9

Renal tubules (proximal and distal):

Answer 9

Regulates blood osmolarity, pH, and absorption of electrolytes (sodium, chloride, potassium)

Question 10

Kidney structure:

Answer 10

Outer renal cortex with an inner renal medulla

Question 11

Decrease in blood pressure causes:

Answer 11

• Secretion of renin
• Activates ADH that causes increased reabsorption of sodium ions and water
• Raises blood volume and pressure and decreasing urine output
