Organ Systems – Working Together
• There are many different organs in the body: the liver, kidneys, heart, even your skin is an organ
• Organ Systems are composed of two or more different organs that work together to provide a common function.
• There are 10 major organ systems in the human body (only 7 listed below. Not listed: Endocrine, Reproductive, Lymphatic/Immune Systems)
Major Role: The main role of the skeletal system is to provide support for the body, to protect delicate internal organs and to provide attachment sites for the organs.
Bones, cartilage, tendons and ligaments.
Major Organs:
Major Role: The main role of the muscular system is to provide movement. Muscles work in pairs to move limbs and provide the organism with mobility. Muscles also control the movement of materials through some organs, such as the stomach and intestine, and the heart and circulatory system.
Skeletal muscles and smooth muscles throughout the body.
Major Organs:
Major Role: The main role of the circulatory system is to transport nutrients, gases (such as oxygen and CO2), hormones and wastes through the body.
Heart, blood vessels and blood.Major Organs:
Major Role: The main role of the nervous system is to relay electrical signals through the body. The nervous system directs behavior and movement and, along with the endocrine system, controls physiological processes such as digestion, circulation, etc.
Brain, spinal cord and peripheral nerves.
Major Organs:
Major Role: The main role of the respiratory system is to provide gas exchange between the blood and the environment. Primarily, oxygen is absorbed from the atmosphere into the body and carbon dioxide is expelled from the body.
Nose, trachea and lungs.Major Organs:
Major Role:
The main role of the digestive system is to breakdown and absorb nutrients that are necessary for growth and maintenance.
Mouth, esophagus, stomach, small and large intestines.
Major Organs:
Major Role:
The main role of the excretory system is to filter out cellular wastes, toxins and excess water or nutrients from the circulatory system.
Kidneys, ureters, bladder and urethra.Major Organs:
