Unit B Conclusion

 

This photograph shows four images of parents with children. In the first image, a young boy (about 4 years old) is laying on an adult’s chest in a grassy location. In the second image, the same child is riding on the shoulders of an adult male. The third image in the group shows a young boy holding hands with an adult male and adult female and jumping into the air. The fourth image shows a young boy sitting on the knee of an adult female, who is also holding a baby, which is presumably a girl because it is dressed in pink.

In Unit B of Biology 30 you studied the human reproductive system as a representative mammalian system responsible for reproducing the organism and carrying on the species.

 

The overarching inquiry for Unit B was this:

  • Describe in detail the structures and function of the human reproductive system.

  • Explain how humans have managed to sustain their existence and increase their population number on a planet that is constantly changing.

  • Analyze the technologies and choices available to humans in the regulation of reproduction.

Specifically, you looked at

  • explaining how species survival is ensured through reproduction

  • identifying and describing the structures and functions of the human reproductive systems

  • explaining how human reproduction is regulated by chemical control

  • describing how cell differentiation and development are influenced by genetic, endocrine, and environmental factors

  • analyzing how sexually transmitted infections and reproductive technologies can prevent or enhance fertility

You learned about the structures and the functions associated with human reproduction and the hormones that regulate reproduction and development, and establish homeostasis. You also studied how environmental factors have an influence on embryonic and fetal development and examined various types of reproductive technologies. You used your understanding of the nervous system and endocrine systems to further explore how they contribute to maintaining equilibrium within the reproductive system.

 

In Module 3 you studied the structures of the male and female reproductive systems: how they function, and how they can be adversely affected by STIs (sexually transmitted infections). In Module 3, you further examined how hormones in the male and female maintain homeostasis and contribute to successful reproduction. Module 4 focused on the development of offspring from fertilization to birth, how cells differentiate to perform certain functions, and how development is regulated by genetic, endocrine, and environmental factors. Together, these modules helped you understand how humans have managed to sustain their existence and increase their population on a planet that is constantly changing.
