Adrenal outer cortex
Target Organ: kidney, DCT
Effect: Increase Na+ reabsorption into bloodstream
Adrenal inner cortex
Hormone: androgens (testosterone and estrogen)
Target Organ: multiple sites in male&female
Effect: maintain secondary sex characteristics
Target Organ: liver (glucose), heart (contractions), vessels (to gut, skin, kidney, periphery, heart, brain, skeletal muscles, bronchioles, pupils)
Effect: -Increase breakdown of glycogen, glucose, and fats
-Increase heart rate and contraction force
-Constrict: gut, skin, kidney, periphery
-Dilate: heart, brain, skeletal muscles
-Dilate: bronchioles, pupils
Thyroid (C cells)
Target Organ: kidney, bone
Effect: Decrease Ca++ in blood and increase Ca++ in bone
Target Organ: Kidney, bone
Effect: Increase Ca++ in bone, stimulates osteoclasts (to chew up old bone)
Target Organ: bone marrow
Effect: Produce RBC's (erythrocytes)
Kidney + Liver
Target Organs: bone marrow, adrenal, hypothalamus, peripheral vessels
Effect: produce RBC's (bone marrow), secrete aldosterone (adrenal gland), secrete ADH (hypothalamus), and constrict (peripheral vessels)
Pancreas (A cells)
Target Organ: liver, skeletal muscle cells
Effect: breakdown of glycogen (into glucose)
Pancreas (B cells)
Target Organ: liver, body cells
Effect: glycogen synthesis, cells uptake of glucose
Target Organ: ??? They DK
Effect: set circadian rythms, induce sleep, inhibit reproduction
Target Organ: Kidney DCT, collecting ducts
Effect: Increase Na+ and H20 excretion
Target Organ: hypothalamus
Effect: reduce appetite
Stomach (G cells)
Target Organ: stomach chief cells, parietal cells, smooth muscles.
Effect: Increase gastric secretions (HCl) and motility
Stomach (D cells)
Hormone: Somatostatin (SST)
Target Organ: Stomach G cells
Effect: Inhibits gastric activity (opposite of gastrin effects)
Parathyroid + Kidney
Target Organ: intestines
Effect: Increase Ca++ absorption from intestinal tract
Hormones: GIP, CCK, secretin, and motilin
Target Organ: stomach, pancreas, gall bladder, intestineal smooth muscles.
Effects: *Look back at ch.24!
