Reproductive System

Overview

The reproductive system is a collection of organs and structures that allow for the creation of new life. It is essential for the continuation of a species and involves both internal and external structures in males and females.

Male Reproductive System

Testes: Produces sperm and the hormone testosterone.
Epididymis: Stores and transports sperm from the testes.
Vas Deferens: Transports sperm from the epididymis to the urethra.
Penis: External organ for delivering sperm to the female reproductive system.
Prostate Gland: Produces fluids that nourish and protect the sperm.

Female Reproductive System

Ovaries: Produce eggs and the hormones estrogen and progesterone.
Fallopian Tubes: Transport eggs from the ovaries to the uterus.
Uterus: The organ where a fertilized egg implants and develops into a fetus.
Vagina: Receives the penis during sexual intercourse and serves as the birth canal.
Cervix: The lower part of the uterus that connects to the vagina.

Fertilization and Pregnancy

Fertilization occurs when a sperm cell from the male joins with an egg cell from the female. This typically occurs in the fallopian tubes. The fertilized egg then implants in the uterus and develops into a fetus over the course of approximately 9 months.

Menstrual Cycle

The menstrual cycle is the monthly series of changes a woman's body goes through in preparation for the possibility of pregnancy. It involves the release of an egg from the ovary, thickening of the uterine lining, and if pregnancy does not occur, shedding of the lining in the form of menstrual bleeding.

Reproductive Health

It is important to maintain reproductive health through regular check-ups, safe sexual practices, and overall wellness. This includes understanding contraception, sexually transmitted infections, and the impact of lifestyle choices on fertility and reproductive function.

Nature of Science

The Practice of Science - A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation. B: The processes of science frequently do not correspond to the traditional portrayal of ''the scientific method.'' C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge. D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

Define a problem based on a specific body of knowledge, for example: biology, chemistry, physics, and earth/space science, and do the following:

Use tools to gather, analyze, and interpret data (this includes the use of measurement in metric and other systems, and also the generation and interpretation of graphical representations of data, including data tables and graphs)
