| 21438727 | Urethra (male) | Tube which carries urine and sperm from the penis. This happens at different times. | |
| 21438728 | Prostrate Gland | A gland within the male reproductive system that is located just below the bladder. | |
| 21438729 | Seminal Vesicles | It makes the fluid for sperm to swim in. | |
| 21438730 | Follicle | It is a small space, filled with liquid, that surrounds the egg cell. | |
| 21438731 | Graafian Follicle | The follicle grows bigger and moves to the edge of the ovary. | |
| 21438732 | Ovulation | When the Graafian follicle bursts and the egg leaves the ovary. | |
| 21438733 | Tubules | The tiny tubes where sperm are made. These are located in the testes. | |
| 21438734 | Ejaculation | Process where sperm is pushed out of the penis by contracting the muscles along the penis. | |
| 21438735 | Embryo | After fertilization occurs, the zygote divides to make a ball of cells that is called the embryo. | |
| 21438736 | Implantation | When the embryo sinks into the thick, spongy lining of the uterus. | |
| 21438737 | Placenta | It provides nutrients and oxygen from the mother to the baby through the umbilical cord. | |
| 21438738 | Umbilical Cord | Joins the embryo (baby) to the placenta | |

| 21438743 | Menstruation | When the lining of the uterus breaks up and slowly moves out the vagina. This process takes about 5 days and occurs every 28 days in females. |
