SC.912.L.16.13 Describe the basic anatomy and physiology of the human reproductive system. Describe the process of human development from fertilization to birth and major changes that occur in each trimester of pregnancy. 

Students will identify and/or describe the basic anatomy and physiology of the human reproductive system. 

Students will describe the process of human development from the zygotic stage to the end of the third trimester and birth.
