The prostate is a small gland located just below the bladder. The gland is only found in men. It is shaped like a doughnut and surrounds the urethra, the tube through which urine flows. The prostate reaches its adult size by the age of 20 and weighs a little less than one ounce.
Zonal marking Zonal marking is a defensive strategy where defenders cover an area of the pitch rather than marking a specific opponent. If an opponent moves into the area a defender is covering, the defender marks the opponent.
Marking today. Today, several modern defensive formations use a mixture of both man-to-man and zonal marking e.g. 3â5â2 formation (which defensively becomes a 5â3â2). This means 5 defenders: 2 stoppers marking man-to-man, 1 sweeper (sweepers always mark by zone), and 2 wingbacks playing almost like end-to-end side midfielders.
