Human Reproduction

Human reproduction is process which ovum and sperm meet in fallopian tubes and become a zygote, than grow become embrio and then become a new individual. Reproduction also has mean a fundamental feature of all known life, each individual organism exists as the result of reproduction.

Human reproduction usually involving sexual intercourse between a man and a woman. The male sex organs are bladder, pubic bone, sigmoid colon, rectum, seminal vesicle, ejaculatory duct, prostate gland, vas deferens, epididymis, testis, scrotum, penis, corpus, penis glans, foreskin, and urethral. But the main male sex organs are the penis and the testes which produce semen and sperm, which as part of sexual intercourse fertilize an ovum in a woman's body. Penis is the male copulatory organ. Penis is make of two different tissues. When the male becomes sexually arous, the penis becomes erect and ready for sexual activity. Erection is occur because blood sinuses within the erectile tissue of the penis become full with blood. The female sex organs are fallopian tubes, ovaries, uterus, cervix, and vagina. But the main female sex organs are the vagina and uterus, which act as the receptacle for the semen, and the ovaries, which produce the female's ovum.

At certain situation, the ovaries release an ovum, which passes through the fallopian tube into the uterus.Then if in the way, it meets with sperm, the sperm penetrate and combine with the egg, it means occur fertilization. But if ovaries not meet with sperm, the egg is flush out with blood menstruation. The fertilization usually occurs in the oviducts, but can happen in the uterus it self. The zygote then implants it self in the wall of the uterus, where it begins the process of embryogenesis and morphogenesis.

After that, zygote grow become embrio until 9 months 10 day, than happen process of birth, which begins contractions of the uterus propel the embrio into the birth canal, which is vagina, finally embrio out of the female and embrio become a new individual, which usually call baby, then the baby breath the oxigens and begins new life.
