The Circulatory

System

The circulatory system is made up of several parts. The main organ is the heart. Other parts of this system are the blood vessels which are the arteries, the veins and the capillaries

The Respiratory

System

The main organs in the respiratory system are the nasalcavity (nose) trachea, lungs, bronchi, and diaphragm.

The purpose of this system is to take in oxygen from the air you breathe and to release carbon dioxide back into the air. As the blood passes through the lungs, it picks up the oxygen and takes it to the cells of the body, where the blood then picks up carbon dioxide and returns it to the lungs.

Each of more than 600 muscles is served by nerves which link the muscle to the brain and spinal cord. Our bodily needs demand that muscles accomplish different chores, so we are equipped with three types of muscle: cardiac, smooth and skeletal.

epidermis, the middle layer is the dermis and the bottom

or underneath layer is the fatty layer.

The hair follicles grow from the fatty layer through the

dermis and exit the skin through pores in the epidermis.
