ENDOCRINE Flashcards
ANTIDIURETIC HORMONES
DIABETES INSIPIDUS
EXCESS DILUTE URINE=?
EXTREME THIRST
NORMAL PERSON? ADH, hypothalamus
Hypothalamus produces vasporessin (ADH)->stored in pituitary gland
ADH released when water in the body becomes too low
ADH retains water in the body by reducing amount of water lost through the kidneys
Therefore, more CONCENTRATED urine
DIABETES INSIPIDUS?
Reduced production of ADH
Kidneys do NOT retain much water, so too much water passed from body
Causing extreme thirst/polyuria
Therefore, more DILUTE urine
2 TYPES OF DIABETS INSIPIDUS?
PITUITARY (CRANIAL)- lack of ADH production
NEPHROGENIC (PARTIAL)- NO response to ADH
