Study Notes
- The text is about the human reproductive system in the context of sexual reproduction.
- Sexual reproduction involves the fusion of the nuclei of two gametes (sex cells) to form a diploid zygote.
- Gametes are haploid cells, containing half the number of chromosomes (23), while a diploid zygote contains the full set (46).
- Female reproductive system components include the ovaries, fallopian tubes, uterus, and vagina.
- The ovary produces ovum (eggs), the fallopian tube is where fertilization occurs, the uterus is where the embryo develops, and the cervix and vagina are parts of the external female genitalia.
- Male reproductive system components include the testes, epididymis, vas deferens, seminal vesicles, prostate glands, and urethra.
- The testes produce sperm, the epididymis stores and matures sperm, the vas deferens transports sperm, seminal vesicles produce fluid for semen, and the prostate glands and urethra contribute to the transport and protection of sperm.
- Fertilization occurs when a sperm penetrates an ovum in the fallopian tube, resulting in a zygote.
- Implantation occurs when the zygote attaches to the uterine wall and begins to develop into an embryo.- Implantation is the attachment of the fertilized egg to the uterine lining.
- Ovum travels towards the uterus through peristalsis movement.
- Once the ovum is fertilized, it becomes impenetrable and the zygote implants into the uterus lining.
- The embryo is protected by the amniotic fluid and covered with the amniotic membrane.
- The umbilical cord transfers oxygen and removes carbon dioxide between the fetus and the mother.
- Food and oxygen from the mother reach the embryo through the placenta.
- The placenta, amniotic fluid, and embryo are housed in the uterus.
- The cervix gradually widens for the baby to pass through the vagina during labor and childbirth.
- Puberty starts around age 10 and ends at 18, with changes in secondary sexual characteristics for both males and females.
- The menstrual cycle consists of the follicular phase and the luteal phase.
- Estrogen production during the follicular phase causes the lining of the uterus to thicken, while progesterone production during the luteal phase maintains the lining for a potential pregnancy.
- Fertilization can occur during ovulation, and if not, menstruation occurs and the uterus lining is shed.
- FSH and LH are hormones produced during the menstrual cycle to stimulate follicle growth and ovulation.
- Methods of birth control include natural, chemical, mechanical, and surgical methods.
- Condoms, diaphragms, and IUDs are examples of mechanical birth control.
- Vasectomies and female sterilization are examples of surgical birth control.
- Fertility treatments include in vitro fertilization (IVF) and artificial insemination.
- Sexually transmitted infections (STIs) are infections transmitted through body fluids during sexual contact.
- HIV is an example of an STI that can compromise the immune system and lead to AIDS.
- Prevention of STIs includes avoiding unprotected sex and sharing needles.
