What is the mechanism leading to CKD?
CKD is caused by a variety of factors including diabetes, hypertension, infection, reduced blood supply to the kidneys, obstruction of the urinary tract and genetic alterations.

What is the pathway of blood being filtered of urea?
The kidneys remove urea from the blood through tiny filtering units called nephrons. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule.
What is the pathway of blood flow through the kidney quizlet?
Pathway of renal blood flow: Renal artery -> segmental arteries -> interloper arteries -> arcuate arteries -> cortical radiate arteries -> afferent arterioles -> glomerulus -> efferent arterioles -> peritubular capillaries -> cortical radiate veins -> arcuate veins -> interlobar veins -> renal vein.
Where does blood travel to after the kidney?
After the kidneys have performed their cleansing function, the filtered, deoxygenated blood leaves the kidneys through the renal vein, moves up the inferior vena cava, and returns to the heart.
What is the pathogenesis of chronic renal failure?
Renal failure in disease of the tubules themselves. It is emphasized that acute renal failure only becomes chronic when interstitial fibrosis develops from the interstitial edema occurring in the early stage of the disease. 4. Renal failure occurring in primary diseases of the renal cortical interstitium.
What is the pathophysiology of nephropathy?
The pathogenesis of diabetic nephropathy is likely to be as a result of metabolic and hemodynamic abnormalities, as seen in diabetes, interacting with each other and with various reactive oxygen species‐dependent pathways.
What is the correct sequence for parts of the renal tubule?
After leaving the renal corpuscle, the filtrate passes through the renal tubule in the following order: proximal convoluted tubule (found in the renal cortex) loop of Henle (mostly in the medulla) distal convoluted tubule (found in the renal cortex)
How urea is transported in the blood to the kidney?
Urea in the terminal IMCD is transported by a specific urea transporter that is stimulated by vasopressin and hyperosmolarity. Although the urea transporter has not been cloned, individuals have been identified who lack the urea transporter.
What is the order of blood vessels in which blood enters the kidney quizlet?
-Blood enters the kidney through the renal artery before flowing into smaller arteries and then into arterioles in the cortex.
Which is the correct order of filtrate flow?
The correct path of filtrate through a nephron starts in the renal corpuscle, which is comprised of the glomerulus and Bowman’s capsule. Filtrate then passes through the proximal convoluted tubule, where the majority of reabsorption takes place.
Which blood vessel takes blood away from kidney?
So, the correct answer is ‘Renal vein’.
How does CKD cause metabolic acidosis?
Healthy kidneys remove acid from the body through urine and they keep the right amount of bicarbonate (base) in the blood. But in CKD, the kidneys can’t remove enough acid, which can lead to metabolic acidosis.
How does CKD affect GFR?
*Your GFR number tells your healthcare provider how much kidney function you have. As chronic kidney disease progresses, your GFR number decreases.
Why does CKD cause hypertension?
The pathophysiology of CKD associated hypertension is multi-factorial with different mechanisms contributing to hypertension. These pathogenic mechanisms include sodium dysregulation, increased sympathetic nervous system and alterations in renin angiotensin aldosterone system activity.
Is diabetic nephropathy and CKD the same?
Diabetic nephropathy is a long-term kidney disease that can affect people with diabetes. It occurs when high blood glucose levels damage how a person’s kidneys function. Diabetic nephropathy is a kind of chronic kidney disease (CKD).
What is the correct sequence of renal tubule segments through which filtrate would flow quizlet?
extra info: The correct order for filtrate flow through a nephron is Glomerular capsule, PCT, loop of Henle, DCT, collecting duct.
Which of the following correctly lists the order of structures through which urine flows after its formation in the nephron group of answer choices?
the glomerular capsule, proximal convoluted tubule, the nephron loop, distal convoluted tubule, and the collecting duct.
Is urea transported by RBC?
Urea apparently permeates the red cell membrane via a facilitated diffusion system, which plays an important role when red blood cells traverse the renal medulla; rapid urea transport helps preserve the osmotic stability and deformability of the cell, and it helps prevent dissipation of extracellular osmotic gradients.
What converts ammonia into urea?
The liver produces several chemicals (enzymes) that change ammonia into a form called urea, which the body can remove in the urine.
What are the major blood vessels associated with the kidney?
The renal arteries are large blood vessels that carry blood from your heart to your kidneys. Renal is another word for kidney. You have two renal arteries. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney.
