Knowledge
Students know:
- The female reproductive system is designed to produce, store, and transport eggs.
- The female reproductive system is composed of the reproductive tract and the mammary glands.
- The male reproductive system is designed to produce, store, and transport sperm.
- The male reproductive system is composed of the testes, seminal vessels, and penis.
- Diseases of the reproductive tract are 1) congenital—affect the function of the gonads or development of reproductive organs, 2) infectious—STDs caused by arthropods, bacteria, Protista, or viruses, or 3) degenerative—abnormal growths, including cancer.
- Basic understanding of mitosis and meiosis.
- Embryogenesis occurs when the fertilized egg (zygote) undergoes its first mitosis. It continues mitosis about once every seven hours, forming a blastula, which embeds in the uterine lining. The blastula then develops into a gastrula, at which stage the germ layers form. The gastrula then develops into an embryo and then a fetus, at which time all the major organ systems form from the three germ layers.
Skills
Students are able to:
- Gather, read, and interpret scientific information about the female reproductive system and its structure, including structures that help in the production, storage, and transport of eggs.
- Gather, read, and interpret scientific information about the female reproductive system and its function, including the production, storage, and transport of eggs.
- Gather, read, and interpret scientific information about the male reproductive system and its structure, including structures that help in the production, storage, and transport of sperm.
- Gather, read, and interpret scientific information about the male reproductive system and its function, including the production, storage, and transport of sperm.
- Compare and contrast the structures and functions of the female and male reproductive systems.
- Communicate scientific information, in multiple formats (e.g., orally, graphically, textually) to explain differences between the structures and functions of the male and female reproductive systems.
- Use scientific literature to identify conditions and diseases that affect the reproductive system.
- Evaluate, based on evidence, how these conditions and diseases affect the body.
- Analyze data in order to make a valid and reliable scientific claim about how the body responds to the identified conditions and diseases in its attempt to maintain homeostasis.
- Use a model to illustrate and describe what occurs during each stage of fetal development.
Understanding
Students understand that:
- The reproductive system is made of several different tissues, and organs that produce, nourish, store, and release gametes.
- The reproductive system closely interacts with the nervous and endocrine systems to regulate several reproductive processes (menstruation, ovulation, hormonal cycles.
- Numerous cells, tissues, and organs are structurally designed to play several different roles in the reproductive process.
- Genetic, environmental, and lifestyle factors can contribute to the development of reproductive disorders.
- Lifestyle choices and various medications can help alleviate reproductive disorders.
- Multiple systems interact to play a part in reproductive function and pathology.
- The mother's circulatory system functions as a mode of transport (nutrient, gas, waste, etc.) for a developing baby.
- The fetus develops various cells, tissues, organs, and systems that mature over a scheduled set of events that occur over a period of nine months.
