Exam 2 Blood Supply Of The Kidneys Flashcards
renal blood flow in a typical 2 adult kidneys ml per minute
Approximately 1,200 ml per minute in both combined
Arteries of the kidneys starts with what and branches into what
Enters the kidney where
The abdominal aorta branches into renal arteries
enters the kidney at the hilum
Where does the efferent arteriole enter
Where does the efferent arteriole leave
Afferent arterioles Enter the nephron at the glomerulus
Efferent arterioles leave the nephron after the glomerulus
Site of filtration
Afferent arteriole divides into a ball of capillaries called the glomerulus
Filtration occurs here
Filtration definition
Movement from high concentration to low concentration under pressure
Arteriole after glomerulus becomes what?
Efferent arteriole divides to form peritubular capillaries
PTC wraps around the ducts of the nephron
Vesa recta what is it and what does it supply?
Tiny branches of efferent arteriole that form loops in the medulla between the PTC of the proximal and distal tubules
The vase recta supplies the ducks of the nephron with nutrients from the blood
Peritubular capillaries merging after the nephron form what?
And what is the blood like after it exits at the hilum?
Merge to form larger veins which merge until renal vein is formed
Renal vein exits at the hilum carrying filtered but deoxygenated blood
Tissue type of capillaries And what this type of tissue is needed for
Simple squamous it is needed for diffusion meaning specifically filtration
What’s unusual about the capillary bed called the glomerulus?
One of the few places where a capillary bed lays between two arterioles
Capillaries typically found between an arteriole and a venule
Arteries and veins branching or merging
Arteries branch
Veins merge
What carries deoxygenated blood that has been filtered of waste. Starts at what until it merges into what?
Peritabular capillaries that eventually merge until they form a renal vein
What does the renal vein merge with
The inferior vena cava
