generally there are special receptors to identify changes in blood pressure.there are osmo receptors and baro receptors present in blood vessels.these sense the changes in blood volume and pressure and pass on information to special centres .
when venous blood flow passes through kidneys these sense the changes in blood volume and pressure.when there is change in blood volume or pressure they release special substance called "RENIN".this renin is released special" JUXTRA GLOMERULAR APPARATUS".
juxtra glomerular apparatus;it includes 3 imp areas.
in afferent arteriole cells called JUXTRA GLOMERULAR CELLS
proximal portion of distal convoluted tubule contains MACULA DENSA.
cells called POLIKISSEN CELLS OR LACIS CELLS.
Renin acts on its substate called angiotensinogen[which is a protein synthesized by liver].then it forms angiotensin1.this reacts with enzyme called angiotensinogen converting factor and forms angiotensin2.this acts on adrenal gland and this release aldosteron which acts on renal tubules and absorb Na+ and also release antidiuretic harmone which absorbs water in renal tubules and effects blood volume and blood pressure.this is sensed by baroreceptors and these send information to higher centres and these higher centers present in medulla send impulses to heart and blood vessels to dilate or contract .thus as a result due to dilation blood pressure decreases or due to contraction bp increases.due to absorption of water blood volume increases or decreases.
THUS KIDNEYS EITHER DIRECTLY AND INDIRECTLY ACT ON HEART TO INFLUENCE BLOOD BP AND VOLUME.
What else can I help you with?
What do kidney regulate in the blood?
They help regulate blood pressure (I think)
What Kidney structures that help to regulate blood pressure?
The glomerulus ...
Explain how antidiuretic hormone can help regulate hypotension Be specific?
it can help by increasing reabsorption of water by the kidney. With the reabsorption, blood plasma volume increases, thus raising blood pressure
How does kidney help regulate blood pressure?
The kidneys help regulate blood pressure by controlling the amount of fluid in the body through filtration of blood and secretion of hormones like renin. Renin helps to regulate blood volume and blood pressure by activating the renin-angiotensin-aldosterone system, which constricts blood vessels and increases blood pressure. Additionally, the kidneys play a role in managing electrolyte levels, which can impact blood pressure regulation.
What organs maintain blood pressure?
From eurekalert:When blood pressure increases the kidneys respond by extracting extra water and salts into the urine, causing blood volume -- and hence pressure -- to fall. But special nerve pathways mean the brain can also regulate urine production and hence influence blood pressure.So, no one organ regulates blood pressure.
what hormone promotes sodium ion by the kidney in order to increase blood pressure and blood volume?
Aldesterone
Besides ridding the body of wastes formed during cell metabolism the kidney adjusts blood chemistry in other ways .What are these three other ways?
The kidney regulates blood pressure by adjusting the volume of blood and levels of sodium and water in the body. It also helps maintain the balance of electrolytes and pH levels in the blood by filtering and excreting excess ions and acids. Finally, the kidney produces hormones like erythropoietin and renin that help regulate blood cell production and blood pressure, respectively.
List 5 hormones which involve the kidney in their function?
Renin: produced by the kidney to help regulate blood pressure by controlling the vascular tone and fluid balance. Erythropoietin: produced by the kidney to stimulate red blood cell production in the bone marrow. Calcitriol: the active form of vitamin D produced by the kidney, important for calcium absorption and bone health. Prostaglandins: locally produced in the kidney to regulate blood flow and filtration rate. Atrial natriuretic peptide (ANP): released by the heart in response to high blood pressure, it acts on the kidneys to increase sodium excretion and decrease blood volume.
How does the kidney regulate blood volume?
The kidneys regulate electrolytes, Ph balance (acid base balance) and blood pressure. The kidneys also filter waste from blood which is excreted in urine. The kidney also produces hormones that aid in the absorption of calcium and production of red blood cells.
Which organ senses the bodys blood pressure?
The baroreceptors located in the walls of the arteries and veins are responsible for sensing changes in blood pressure. These receptors send signals to the brain to help regulate blood pressure levels in the body.
What is the function of the left kidney?
The left kidney functions similarly to the right kidney, filtering waste and excess fluids from the blood to form urine. It also helps regulate blood pressure, maintain electrolyte balance, and produce hormones that contribute to red blood cell production.
How does juxtaglomerular apparatus help regulate blood pressure and filtration rate?
The apparatus is a microscopic structure in the kidney, the specific location of it helps to regulate the renal blood flow and filtration rate. It is regulated by secreting renin which activates the
