Renal capsule
- a dense fibrous connective tissue that surrounds each kidney.
Nephron
-the functional unit of the kidney
Pararenal Fat
-a layer of adipose tissue that surrounds the renal capsule
-it cushions and protects the kidney
Renal Fascia
-a layer of loose connective tissue that surrounds the pararenal fat.
Renal Fascia
______ is responsible for anchoring the kidney, surrounding the peritoneum, and the abdominal wall.
Glomerulus
-a high pressured, fenestrated capillary with large holes between the endothelial cells
renal corpuscle & renal tubule
What are the components of the nephron?
bowman capsule & glomerular capillaries
What are the components of the renal corpuscle?
Bowman's capsule
-surrounds the glomerulus
-actively participates in plasma filtration
-contains a urinary space which allows for filtrate to pass through to Proximal convoluted tubule.
Lamina interna, lamina densa, lamina externa
What are the three layers of the basement membrane?
Afferent arteriole
-blood plasma travels through this and into the glomerulus.
b
Podocytes are part of the :
a) parietal layer
b) visceral layer
lamina rara externa
This layer is fused to the epithelial cell layer.
Lamina densa
This layer is located in the middle of the basement membrane.
lamina rara interna
This layer is fused to the endothelium.
fenestrated endothelial cells
-contains pores that are 70-100 nm in diameter
-retains blood cells
-allows large, fluid, dissolved solutes, and plasma proteins to be filtered across
basement membrane
- a multilayered membrane that does not permit filtration of plasma proteins, especially albumin
