The process of filtration of the blood in the Bowman's capsule is ultrafiltration (or glomerular filtration), and the normal rate of filtration is 125 ml/min, equivalent to ten times the blood volume daily. Measuring the glomerular filtration rate (GFR) is a diagnostic test of kidney function.
penalty kick. n. 1. (Soccer) soccer a free kick at the goal from a point (penalty spot) within the penalty area and 12 yards (about 11 m) from the goal, with only the goalkeeper allowed to defend it: awarded to the attacking team after a foul within the penalty area by a member of the defending team.
A goal may not be scored directly from an indirect free kick, rather it must be touched by a second player before a goal can be scored. If the ball goes in goal directly from an indirect free kick, a goal kick is awarded to the defending team. As with all restarts of play, if the ball goes directly into the kicker's own goal from an indirect free kick a corner kick is awarded to the opposing team.
