Question
Chapter 40, Problem 8SQ
Summary Introduction
Introduction: Hormone is important to regulate the urine’s concentration and its composition. Hypothalamus gland signals the pituitary gland to release antidiuretic hormone (ADH). ADH is a hormone that increases the reabsorption of the water through passive transport protein called aquaporins. Another hormone called aldosterone secreted by adrenal cortex increases the sodium reabsorption. Both, ADH and aldosterone help in the formation of concentrate urine.

- Explain well asaparrow_forwardRegulation of filtration ratea. Glomerular filtration rate (GFR) remains relatively constant, but may increase or decrease as required.b. Increased activity of the sympathetic nervous system can maintain blood pressure with minimal change in GFR.c. When the macula densa senses decreased amounts of chloride, potassium, and sodium ions in the last part of the ascending limb of the nephron loop, it causes juxtaglomerular cells to release renin.d. Renin release triggers a series of changes leading to vasoconstriction of afferent and efferent arterioles, which minimizes any decrease in glomerular filtration rate, and also stimulates aldosterone secretion,which stimulates tubular sodium reabsorption.arrow_forwardConstriction of the efferent arteriole of the renal corpuscle will cause ________________ to rise.
