Individually, your chances of getting pregnant are about 20% in any given month. Research suggests that out of 100 couples having regular, unprotected sex: 20 get pregnant within a month. 70 get pregnant within 6 months. 85 get pregnant within a year. 90 get pregnant within 18 months.
The filtrate is composed of water, ions (sodium, potassium, chloride), glucose and small proteins (less than 30,000 daltons -- a dalton is a unit of molecular weight). The rate of filtration is approximately 125 ml/min or 45 gallons (180 liters) each day.idney Filtration. In the nephron, approximately 20 percent of the blood gets filtered under pressure through the walls of the glomerular capillaries and Bowman's capsule.
The above are filtered in preference to other components of blood based on particle size. Water and solutes of relative molecular mass less than 68,000 form the filtrate. Blood cells and plasma proteins are not filtered through the glomerular capillaries because they are relatively larger in physical size. The water and salts forced out of the glomerular capillaries pass into the Bowman's Capsule and are called the glomerular filtrate. Glomerular filtrate is formed at a rate of above 125 cm3 per minute in humans. This volume is approx. 20% of the plasma delivered during that time.
