Each kidney is surrounded by three main layers. From outermost to inner-most, the layers are as follows: Renal capsule – connective tissue that helps maintain the kidney’s structural integrity and shape, protecting its internal tissue (Cook et al, 2021b).

FUNCTIONAL RENAL ANATOMY Each kidney in an adult weighs about 150 g and is roughly the size of one’s fist. If the kidney is sectioned (Fig. 23.1), two regions are seen: an outer part, called the cortex, and an in-ner part, called the medulla. The cortex typically is reddish brown and has a granulated appearance. All of the glomeruli,
Renal Blood Flow Autoregulation * Reduce RBF & GFR * Reduce Salt & H2O Excretion *
Describe how renal blood flow can be determined from the clearance of p-aminohippurate (PAH) and the hematocrit, and discuss the factors that influence renal blood flow.
