Card Set Information
Organ systems help organisms
get energy, use energy to run their bodies and move, reproduce, get rid of waste, protect their bodies, and coordinate all the functions of a body.
Organ systems are formed from
groups of organs working together.
Nerves detect a stimulus in the environment and send a signal to the brain through the
spinal cord. The brain sends a signal to respond.
The muscular system
allows movement of body parts. It works with the skeletal system to help you move.
The skeletal system
is made up of bones, ligaments, and cartilage. It supports the body and protects important organs. It also makes blood cells.
The respiratory system
gathers oxygen from the environment and gets rid of carbon dioxide from the body. The exchange occurs in the lungs.
The lymphatic system
returns leaked fluid back to the blood. As a major part of the immune system, it has cells that help get rid of invading bacteria and viruses.
The endocrine system
makes chemical messages that help to regulate conditions inside the body. They also influence growth and development.
The cardiovascular system
moves blood through the body. The heart is the pump for this system. Blood flows through blood vessels.
The excretory system
gets rid of the body's wastes. The urinary system removes wastes from blood. The skin, lungs, and digestive system also remove wastes from the body.
