What do the peritubular capillaries drain into?
What do the peritubular capillaries drain into?
Peritubular capillaries and vasa recta have a more standard anatomical arrangement, with afferent arterioles and efferent venules. Since a capillary bed (the glomerulus) drains into a vessel that in turn forms a second capillary bed, the definition of a portal system is met.
Where do peritubular capillaries feed into?
Peritubular capillaries provide nutrients and oxygen to the renal cortex. Therefore, a larger portion of the peritubular capillaries is in the renal cortex. They surround the proximal and distal tubules.
Which of the following is the correct sequence of blood flow through the kidneys on its route to the glomeruli of the nephrons?
Which of the following represent the correct sequence of blood flow through the nephron? Blood enters the kidney through the renal artery – afferent arteriole – glomerulus – efferent arteriole – peritubular capillaries – renal vein – exits the kidney.
What are the structural differences between Juxtamedullary and cortical nephrons and between the capillary beds?
The major difference between cortical nephrons and juxtamedullary nephrons are the length of the loops of Henle. In cortical nephrons, the glomeruli, proximal and distal convoluting ducts, and loops of Henle stay limited to the cortex. In juxtamedullary nephrons, they extend into the medulla.
What is the function of the peritubular capillaries quizlet?
peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron.
What is the function of the blood capillaries surrounding the nephron?
The function of blood capillaries surrounding the nephrons are: 1. They absorb the substances like glucose, amino acids, water etc. from the glomerular filtrate which are useful for the body.
What is the correct order of flow through a nephron?
Correct answer: 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.
What is the role of the cortical vs Juxtaglomerular nephrons that is what is the function of each?)?
The loop of Henle of the cortical nephron extends only to the outer renal medulla while that of the juxtamedullary nephron extends to the deeper of the renal medulla. Cortical nephrons are mainly involved in the excretory and regulatory functions of the body while juxtamedullary nephrons concentrate or dilute urine.
Do Juxtamedullary nephrons have peritubular capillaries?
In the juxtamedullary nephrons, the peritubular capillaries have a specialization called the vasa recta, which are long, hairpin-shaped blood vessels that follow the same course as the loop of Henle. The vasa recta serve as osmotic exchangers for the production of concentrated urine.
