Urinary System

Question 1

Functions of the uninary system (5)

Answer 1

• Excretion of waste products that are created when food is transformed into energy (metabolism).
• Maintains the correct balance of water and electrolytes (salts) within the body.
• Regulates blood pressure and sodium re-absorption.
• Regulates the production of blood cells and platelets.
• The metabolism of vitamin D (by converting it into an active hormone)

Question 2

Uninary system components (4)

Answer 2

• Kidneys
• Ureters (tubes that connect the kidneys to the bladder)
• Bladder
• Urethra (the tube through which urine exits the body).

Question 3

Urinary system process (6)

Answer 3

• Blood Stream
• Kidneys
• Ureters
• Bladder
• Urethra
• Out of Body

Question 4

nephron definition

Answer 4

A tiny filtering system in the kidney

Question 5

Parts of a nephron (2)

Answer 5

• renal corpuscle
• renal tubule

Question 6

glomerulus function

Answer 6

• filters blood

Question 7

Proximal tubule function

Answer 7

• returns needed substances to your blood and removes wastes

Question 8

Bowman’s capsule function

Answer 8

• cradles the glomerulus

Question 9

Nephron filtering process (9)

Answer 9

• Blood
• Filters through Glomerulus (in the Bowman’s capsule)
• Filtrate moves through Proximal Tubule
• Loop of Henle
• Distal Tubule
• Collecting Duct
• Ureter
• Bladder
• Urethra

Question 10

Parts of the renal corpuscle (2)

Answer 10

• glomerulus
• bowman’s capsule

Question 11

Renal Tubule parts

Answer 11

• proximal tubule (proximal convoluted tubule)
• loop of henle
• distal tubule

Question 12

proximal tubule reabsorbs..?

Answer 12

Glucose

Question 13

What is reabsorbed in loop of henle? (2)

Answer 13

• Various ions
• some water molecules

Question 14

The distal tubule controls..?

Answer 14

The PH of the blood

Question 15

Where is water reabsorbed into the blood stream?

Answer 15

from the filtrate in the collecting duct

Question 16

Effects of massage on urinary system (3)

Answer 16

• promote the excretion of metabolic wastes by increasing circulation.
• help to reduce water retention in the body by moving fluid back toward the kidneys for filtration.
• increase urine output because this excess fluid moving through the kidneys ends up in the bladder for elimination. (A horse will quite often need to urinate during or just after a bodywork session.)
