Hormones
Filtration, Metabolism
Hormone | Target(s) | Action | Origin | Responds to |
---|---|---|---|---|
Epinephrine - Filtration | Blood Vessels | Constrict --> LOWER GFR | Adrenal MEDULLA | High GFR |
Renin | Blood Vessels | Constrict --> LOWER GFR | Jg Complex | High GFR |
ANP | Renal | Decrease Na+ reabsorption --> Increased Na+ Excretion | Heart | HIGH Na+ |
Aldosterone | Renal | Increase Na+ Reabsorpton --> Decrease Na+ Excretion & Increase K+ Secretion --> Increase K+ Excretion | Adrenal CORTEX | LOW Na+, HIGH K+ |
ADH | Renal | Volume & Osmolarity Mechanisms | Hypothalalmus --> POST. Pituitary | Plasma Volume, Extracellular Osmolarity |
Insulin | Adipose, Muscle, Liver | 1. stimulats Glucose & AA entry into cells --> Inhibits Glycofen catabolism; 2. FA, Glycogen, & Protein Synthesis | BETA cells - Pancreas | Increase in Blood Glucose or AA - HYPOglycemic - Absorptve |
Glucagon | Liver, Fat | Glycogenolysis --> Glucose, Lipolysis --> Ketones & FA | ALPHA cells -Pancreas | LOW Blood Glucose or HIGH AA - HYPERglycemic - POSTabsorptive |
Epinephrine - metabolism | Liver, Muscle, Adipose | promotes Glycogenolysis & Lipolysis | Adrenal MEDULLA | LOW Blood Glucose --> stimulates Receptors --> RAISE Sympathetic --> Secretion - HYPERglycemic - POSTabsorptive |
