Interaction s of the Human Body

Human Organ Systems Tissues, organs and organ systems help provide cells with nutrients, oxygen and waste removal The human organism has systems for digestion, respiration, circulation, reproduction, excretion, movement, control and coordination.

Human Body Systems THE DIGESTIVE SYSTEM Consists of organs that are responsible for the mechanical and chemical breakdown of food This breakdown process results in molecules that can be absorbed and transported to cells.

Human Body Systems THE RESPIRATORY SYSTEM Cells use oxygen to release the energy stored in food. Helps us to smell and create sound. Supplies oxygen and removes carbon dioxide Through breathing, inhalation and exhalation, the respiratory system facilitates the exchange of gases between the air and the blood and between the blood and the body’s cells.

THE EXCRETORY SYSTEM Responsible for removing waste from the body Disposal of waste molecules, elimination of liquids and gaseous wastes. The major components are: Kidneys, bladder, lungs, and skin Human Body Systems

THE CIRCULATORY SYSTEM Moves blood, oxygen and nutrients through the body The major components are: The Heart: About the size of two adult hands held together, the heart rests near the center of the chest. Thanks to consistent pumping, the heart keeps the circulatory system working at all times. Veins: Veins carry deoxygenated blood to the lungs where they receive oxygen. Blood: Blood is the transport media of nearly everything within the body. It transports hormones, nutrients, oxygen, antibodies, and other important things needed to keep the body healthy. Arteries: Arteries carry oxygen-rich blood away from the heart and where it needs to go.

Human Body Systems THE NERVOUS SYSTEM Consists of the brain, spinal cord, sensory organs, and all the nerves that connect these organs with the rest of the body ENDOCRINE SYSTEMS The collection of glands that produce hormones that regulate growth and development, tissue function, and reproduction.

Human Body Systems SKELETAL AND MUSCULAR SYSTEM Work together to support and allow movement of the body. The Skeletal System includes all the bones and joints in the body and protects internal organs. The muscular system permits movement of the body, and aids in the circulation of blood
