What is the primary function of the kidneys?
Elimination of waste products
Which part of the nephron is responsible for forming the ultrafiltrate of plasma?
Glomerulus
What is a characteristic of the renal tubules in the kidney?
Participate in the reabsorption of glucose and amino acids
Why is the papillary blood flow considered low compared to the cortex and medulla?
Maximal concentration of tubular fluid in the papilla
Which part of the nephron surrounds the glomerulus at the beginning?
Proximal tubule
What is a potential consequence of high intraluminal concentrations of toxicants in the papilla?
Diffusion into papillary tubular cells causing injury
What is the primary reason why the renal cortex is more susceptible to toxic injury compared to the renal medulla?
The cortex has a higher concentration of toxicants due to preferential delivery.
