Mechanically, ultrafiltration is the process that depends on the pressure gradient and focuses on the action of membrane filtrate against the semipermeable membrane to form the fluid. The main principle of ultrafiltration depends on the force like pressure or concentration gradient. These molecules must pass through three layers during this process: the capillary endothelium, the basement membrane and the Bowman's capsule epithelium The organs involved in the human excretory system are a pair of kidneys, a pair of ureters, the urinary bladder, and the urethra. Ultrafiltration is the process where the blood is filtered to allow some substances to enter the nephron to get rid of waste products. Scope 4. It operates purely based on the size exclusion principle. is extracted from the blood. It comprises 95 % water and 5% wastes such as ions of sodium, potassium and calcium, and nitrogenous wastes such as creatinine, urea and ammonia. The high pressure is created because the efferent arteriole is narrower than the afferent arteriole. The process of ultrafiltration occurs in the Bowman's capsule of the nephron. Dissolved metal ions as low-molecular weights or hydrated ions could easily transmit UF membranes, because their membranes have pores that are greater than dissolved metal ions. Described in other terms, 150 liters of protein free ultrafiltrate passes from the primary capillary bed in the kidney at the glomerulus into the proximal nephron to be acted upon by renal epithelium of the nephron, reabsorb solutes and water and secrete the appropriate solutes .
