Study Notes
Human Reproductive System
- The human reproductive system is responsible for producing offspring.
- The male reproductive system is responsible for producing sperm, carrying them to the female body, and participating in the fertilization process.
- The female reproductive system is responsible for producing eggs, receiving and containing the sperm, encouraging fertilization, and facilitating the development and nurturing of the fetus.
Male Reproductive System
- Penis: The male organ for sexual intercourse. It has three internal chambers.
- Scrotum: A loose pouch-like sac of skin that hangs behind the penis. The scrotum holds the testicles.
- Testicles (Testes): Oval-shaped organs about the size of large olives. They lie in the scrotum and create sperm.
- Epididymis: A long, coiled tube that rests on the backside of each testicle. It carries and stores sperm cells.
- Vas Deferens: A long, muscular tube that carries mature sperm to the urethra.
- Ejaculatory Ducts: Formed from the vas deferens and seminal vesicles, emptying into the urethra.
- Urethra: A tube that carries urine from the bladder to outside of the body. In males, it also transports semen.
- Seminal Vesicles: Sac-like pouches near the base of the bladder. They produce a sugar-rich fluid that provides sperm with energy for movement.
- Prostate Gland: A walnut-sized structure below the urinary bladder. It contributes fluid to the ejaculate, (semen).
- Bulbourethral Glands (Cowper's Glands): Pea-sized structures near the urethra, producing a clear, slippery fluid that empties into the urethra.
Female Reproductive System
- Ovaries: Small, oval-shaped glands located on either side of the uterus. Ovaries produce eggs and hormones.
- Fallopian Tubes (Oviducts): Narrow tubes attached to the upper part of the uterus, acting as pathways for eggs to travel to the uterus.
- Uterus (Womb): A hollow, pear-shaped organ, housing the developing fetus. The uterus is divided into the cervix and the corpus (main body).
- Cervix: The lower part of the uterus, opening into the vagina.
- Vagina: A canal that joins the cervix to the outside of the body.
- Labia Majora: Enclose and protect other external reproductive organs.
- Labia Minora: Lie inside the labia majora, surrounding openings to the vagina and urethra.
- Clitoris: A small, sensitive protrusion where the labia minora meet.
- Bartholin's Glands: Located next to the vaginal opening, producing mucus.
Chromosomes and Reproduction
- Chromosomes contain genetic information responsible for unique traits.
- Sex cells (gametes) have 23 chromosomes (haploid).
- Regular body cells have 46 chromosomes (diploid).
- Fertilization, the fusion of sperm and egg, results in a zygote with 46 chromosomes.
Egg Production
- Females are born with approximately two million egg cells.
- About every 28 days, an ovum is released.
- Cilia sweep the ovum from the ovary into the fallopian tube.
Stages of Development
- Fertilization: The sperm penetrates the ovum and their nuclei fuse.
- Zygote: The fertilized ovum
- Embryo: The developing baby, from implantation to the third month of pregnancy. A developing baby during the first 8 weeks.
- Fetus: The developing baby after the third month of pregnancy. The developing human after 9 weeks.
- Birth: The nine-month (approximately) process of pregnancy culminating in the delivery of the child.
