Each nephron consists of small blood capillaries called glomerulus, and the renal tubule. Urea, and water forms urine as it passes through the nephrons and down the renal tubules of the kidney. The two ureters are narrow tubes that carries urine from the kidneys to the bladder, the bladder is an organ located in the lower abdomen, its walls will relax and expand in order to hold the urine and as it contracts the urine will empty. The urethra allows urine to pass outside the body. Male reproductive system has a bladder, prostate, urethra, penis, and testicles, to produce and transport sperm and will secrete male sex hormones responsible for maintaining the male reproductive system. Female reproductive system has ovaries, fallopian tubes, a uterus, cervix and vagina. The ovaries produce the female egg cells, then after reproduction the fertilized egg then moves to the uterus and the uterine lining has to thicken in order to prepare for
