SCN3230-ABED_1: Unit B Introduction

Introduction

Amazingly, humans have managed to sustain their existence and increase their population dramatically on a planet that is constantly changing. One reason this has been possible is sexual reproduction.

This unit of Biology 30 investigates the human reproductive system as a representative mammalian system responsible for reproducing the organism and preserving the species. You will learn about the structures and the functions associated with human reproduction and the hormones that regulate reproduction and development as well as establish homeostasis. You will study how environmental factors influence embryonic and fetal development. You will examine various types of reproductive technologies.

You know that a characteristic of living organisms is that they are able to reproduce. Although reproduction is not necessary for individual survival, reproduction is necessary for the survival of the species. Reproduction produces new individuals of a species, either identical to or variations of the parent(s).

You will use your understanding of the nervous system and endocrine systems to explore further how they contribute to maintaining equilibrium within the reproductive system and to the homeostasis of the body. You will develop a deeper understanding of the structures and functions of your own reproductive system and those of the opposite sex. This exploration will help you develop an appreciation for the miracle of life - from conception, through development, to birth.

Unit B has two modules:

Module 3 focuses on the structures of the male and female reproductive systems, how they function, and how they can be adversely affected by STIs (sexually transmitted infections). You will study how hormones in the male and female maintain homeostasis of reproduction.
Module 4 focuses 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, the modules support your inquiry into how humans have managed to sustain their existence and increase their population on a planet whose environments change constantly.

At the completion of this unit, you will write a supervised Midterm Exam.
