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.
Disadvantages of zonal marking â It can be more complicated to deliver the zonal system to players as each player has a job to do. Every player must know their job and do their job. â You can leave attackers unmarked potentially allowing them to get a running jump for the ball. This can give the attackers a better chance to make clean contact.
