Grade 6 - Internal Systems

Students will be introduced to the four body systems: excretory, reproductive, hormonal, and

nervous.

Students learn how each system works, its function in the body and the way they interconnect.

The excretory system is important for removing waste from the body. An experiment with a

coffee filter models how the kidneys filter the blood. The lungs remove unwanted gasses such

as carbon dioxide and the skin plays a part in removing water and salts.

The reproduction system is important for the survival of all species. It produces the gametes

which lead to the development of an embryo, fetus and offspring. The functions of the parts of

the male and female anatomy are described. Differences between sexual and asexual

reproduction are explained.

The endocrine or hormonal system regulates processes in the body using hormones. The

hormones act in the cells to help your body function.

The nervous system relays messages from your brain to other parts of the body. Neurons make

connections that affect the way you think, learn, move, and behave. The brain is the centre of

the nervous system and different parts of the brain have different functions.

Plants and animals have body systems similar to humans with some differences. Indigenous

people used plants to help with the different systems.
