15 Read the following passage. Baca petikan berikut. Excretion is a process eliminating waste materials from our body. These waste products become toxic if they are left to accumulate in our body. The human urinary system is part of the excretory system and the kidneys are the main organs. The kidneys filter the blood to removed waste products into urine. The ureters carry the urine from the kidneys to the urinary bladder where the urine is stored before iti is removed. Urine is passed out through the urethra when the muscles in the wall of the bladder contracts. Perkumuhan merupakan satu proses yang menyingkirkan bahan buangan dari badan kita. Bahan buangan ini menjadi bertoksik jika terkumpul di dalam badan kita. Sistem urinari manusia adalah sebahagian daripada sistem perkumuhan dan ginjal merupakan organ utama. Ginjal menapis darah untuk menyingkirkan bahan buangan ke dalam air kencing. Ureter mengangkut air kencing dari ginjal ke pundi kencing di mana air kencing disimpan sebelum disingkirkan.
