WebHormonal regulation of the female reproductive system involves hormones from the hypothalamus, pituitary, and ovaries. In addition to producing FSH and LH, the anterior portion of the pituitary gland also produces the hormone prolactin (PRL) in females. Prolactin stimulates the production of milk by the mammary glands following childbirth. Webbalance and to maintain the osmolarity of the body by regulating water balance. 2. Reabsorption and secretion of water and solutes is governed by concentration gradients and secondary active transport. 3. Healthy people use hormones to regulate osmolarity (ADH), to regulate K+ (aldosterone), and to regulate fluid volume (ADH, aldosterone, or ...

WebWhen the osmolarity of blood plasma and interstitial fluid increases above a certain point, osmoreceptors in the hypothalamus are stimulated and send nerve impulses to the neurohypophysis, triggering the secretion of ADH into the bloodstream. ADH acts on the kidney by increasing the water permeability of principal cells lining the collecting ducts. WebHormonal Regulation of the Excretory System Maintaining a proper water balance in the body is important to avoid dehydration or over-hydration (hyponatremia). The water concentration of the body is monitored by osmoreceptors in the hypothalamus, which detect the concentration of electrolytes in the extracellular fluid. fake percocet a333
