What is the Negative feedback mechanism of KIDNEY of the body?
The negative feedback mechanism of the kidney involves the regulation of blood pressure through the renin-angiotensin-aldosterone system. When blood pressure drops, the kidney releases renin, which leads to the production of angiotensin II and aldosterone, increasing blood volume and constricting blood vessels to raise blood pressure back to normal levels. Once blood pressure is restored, the production of renin decreases, thus inhibiting further release of angiotensin II and aldosterone.
Why do they have to keep giving blood for renal artery?
this is because the decrease in blood flow to the kidney will trigger the RENIN ANGIOTENSIN mechanism, which stimulates the Increase of Arterial Blood Pressure to get the kidney more blood, also the kidney one tof the sensetive organs to ischemia
What is systemic blood circulation to the kidney?
in human antomy
What happens to filtrate volume when systemic blood pressure is decreased?
Filtrate volume decreases when systemic blood pressure decreases.
What is used to protect mechanism used to protect the glomerulus from minor changes in blood pressure?
The mechanism used to protect the glomerulus from minor changes in blood pressure is called autoregulation. This process involves adjustments in the diameter of the afferent and efferent arterioles, which help maintain a relatively constant glomerular filtration rate (GFR) despite fluctuations in systemic blood pressure. Key factors in this autoregulatory response include myogenic mechanisms and tubuloglomerular feedback. These systems work together to ensure stable kidney function and protect the glomeruli from potential damage caused by pressure variations.
Which part of the systemic circuit has the highest blood pressure?
The blood pressure is the highest in the arteries. It will decrease continuously as it flows through the systemic circuit.
The greater the the pulse pressure the lower the pressure gradient driving blood from the aorta through the systemic circulation?
This statement is not accurate. Pulse pressure is the difference between systolic and diastolic blood pressure and is related to the elasticity of arteries. It does not directly affect the pressure gradient driving blood through the systemic circulation, which is mainly determined by the overall systemic vascular resistance.
The cellular transport mechanism that depends upon blood pressure?
Passive transport is the cellular transport mechanism. This all depends on the blood pressure.
What structure has the lowest blood pressure in the systemic circulation?
in the capillaries
What do kidney regulate in the blood?
They help regulate blood pressure (I think)
What hormone dilates systemic arteries and increases blood flow to the kidneys causing urinary output?
The hormone responsible for dilating systemic arteries and increasing blood flow to the kidneys, thereby promoting urinary output, is atrial natriuretic peptide (ANP). ANP is released by the heart's atria in response to increased blood volume and pressure. It acts to reduce blood pressure by promoting vasodilation and enhancing sodium excretion, leading to increased urine production. This mechanism helps regulate fluid balance and blood pressure in the body.
The blood pressure in the systemic arteries is greatest during what?
ventricular systole
