Question

Describe the properties of the ultrafiltrate of plasma.

Answer 1

ANSWER -

ULTRAFILTRATION

• Due to the pressure gradient, liquid part from the blood filtfiltrates out of the glomerulus passes to the Bowman's Capsule.
• This extra force filtration is known as Ultrafiltration.
• Semipermeable membrane is found in the filtrate, in response to transmembrane pressure gradient.
• Subendothelial basal membrane is the nature of filtrate.
• Filter pore, Pore radius 29 +_ 10 A.
• This is the first step of urine formation, filtrate is known as ultrafiltrate. Kidney can retain small particle like plasma protein,
• Filter barrier is a combination of capilleey walls and structure in Bowmans capsule.

In plasma,

Volume (ml)	Protein (mg/dl)	Glucose (md/dl)	Osmolarity
15000	7000	85	290
