Study Notes
- Platelets assist blood clotting.
- Red blood cells transport hydrogen and oxygen gas.
- White blood cells fight against infection.
- Nutrients are required for cellular metabolism.
- Proteins create osmotic pressure, aid in clotting, and buffer blood.
- Hormones are known as chemical messengers.
- Water provides a fluid environment.
- Salt helps in metabolic activity.
- Wastes are produced by cellular metabolism.
Adrenal Medulla
- The adrenal medulla is a small organ at the top of the kidney.
- Epinephrine and norepinephrine stimulate fight-or-flight responses.
Adrenal Cortex
- Glucocorticoids (Cortisol) are hormones that respond to stress.
- Mineralocorticoids (Aldosterone) balance water and salt and regulates how much water is retained through urine.
Anterior Pituitary
- TSH (Thyroid Stimulating Hormone) stimulates thyroid glands.
- ACTH (Adrenocorticotropic hormone) stimulates the adrenal cortex gland.
- Gonadotropin hormones stimulate gonads.
Hypothalamus
- HRH (Hypothalamic-Releasing Hormone) regulates anterior pituitary hormones.
- ADH (Anti-Diuretic Hormone) promotes water absorption by kidneys.
- Parathyroid hormone maintains blood calcium and phosphorus levels.
- Thyroid hormones increase metabolic rates.
- Insulin lowers blood sugar.
- Glucagon raises blood sugar.
