The peripheral nervous system includes all the nerves in your body that bring messages to the central nervous system and from the CNS to the muscles.
Which system allows air to enter the lungs?
The Human Circulatory System. In order for blood to provide oxygen to the body, the body must have a way of obtaining that oxygen. The respiratory system allows air to enter the lungs and for oxygen to diffuse into the blood en route to the body's tissues.
Which system transports blood throughout the body?
The Circulatory & Respiratory Systems. The circulatory system is responsible for transporting blood throughout the body. It consists of the heart and blood vessels known as veins, arteries and capillaries. Think of blood vessels as the highways of the body, bringing important cargo to and from the cells.

Kidneys are significant organ of the excretory system. They are bean-shaped structures located on either side of the backbone and are protected by the ribs and muscles of the back. It functions by filtering excess water and removing harmful toxins from the blood. Along with excretion, kidneys also produce a hormone called Renin, which regulates blood pressure.
How are the lungs structured?
In humans, a pair of lungs are structured in such a way that it facilitates the exchange of gases. They are lined by a thin membrane, the presence of bronchioles – the smaller tubes, alveoli – a balloon-like structure and the group of blood capillaries, which expands the surface area for the exchange of gases.

For example, the immune system is not a organ system but rather a collection of organs and tissues that work together to protect us from illness.
Can you identify this organ system?
Integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive, and digestive are the 11 organ systems of the body. Although each of your 11 organ systems serves a distinct purpose, each organ system is also dependent on the others, either directly or indirectly. For example, your skin is a direct extension of your immune system. Whenever bacteria, viruses, or other foreign particles enter your body, they first encounter one of your 11 major organ systems. If they make it past that first line of defense and into your bloodstream, then they have reached one of your many blood cells.
