Function
Renal fascia is not part of the filtration membrane of the kidneys. The filtration membrane consists of the glomerular endothelium, podocytes, and the basement membrane, which together form the barrier that filters blood to form urine in the kidneys. Renal fascia is a layer of connective tissue that surrounds the kidney and helps support it in place.
The tissue that covers the kidneys is a connective tissue. There are actually three layers of tissue that covers the kidneys, the renal fascia, adipose capsule, and renal capsule.
Epithelial tissue is well-suited for diffusion, osmosis, and filtration processes. The thin structure of epithelial cells allows for efficient diffusion and osmosis, while their selective permeability facilitates filtration by allowing only certain substances to pass through. Additionally, epithelial tissues are often found lining surfaces where these processes commonly occur, such as in the intestines or kidneys.
fascia
Simple squamous epithelium is the epithelial tissue that easily allows for material to diffuse through it due to its thin structure and flat shape. This type of epithelium is found in areas where rapid diffusion or filtration is necessary, such as in the lungs for gas exchange or the kidneys for filtration of blood.
In the kidney, simple squamous epithelium lines the Bowman's capsule and the glomerulus. In this case, the ability of simple squamous epithelium to provide rapid filtration and diffusion is instrumental to the kidney's function, as the kidney filters about 180 liters of blood per day !
Connective tissue would be better suited to cushion the kidneys against a blow due to its more elastic and supportive properties compared to epithelial tissue, which primarily functions as a protective covering. Connective tissue, such as adipose tissue or the renal capsule, can provide a cushioning effect to absorb and distribute the impact of a blow, helping to protect the kidneys from injury.
Filtration
yes
stabilizes the position of the kidneys by holding them in their normal position
Mostly fatty tissue. Mammary glands are modified sweat glands.
Yes, there are pressure receptors in the kidneys.
