The male reproductive system contains two main divisions: the testes where sperm are produced, and the penis which discharges the sperm as semen (this is known as an ejaculation). In humans, both of these organs are outside the abdominal cavity. Having the testes outside the abdomen facilitates temperature regulation of the sperm, which require specific temperatures to survive about 2-3 °C less than the normal body temperature i.e. 37 °C. In particular, the extraperitoneal … WebThe cell cycle is the of steps that cells take to grow, develop, and reproduce. It can be broken down into five steps: G1 Phase S Phase G2 Phase M Phase Cytokinesis G1 Phase During the G1 Phase, the cell grows and stores up energy that it will use during cell division. Nutrients are taken in and all the usual cell processes take place.
