Name the different levels of structural Organization that make up the human body.
Chemical level
Atoms combine to form molecules
Cellular level
Cells are made up of molecules
Tissue level
Tissues consist of similar types of cells
Organ level
Organs are made up of different types of tissues
Organ system level
Organ systems consist of different organs that work together closely
Organismal level
The human organism is made up of many organ systems.
Integumentary system, Skeletal system, Muscular system, Nervous System, Endocrine system, Cardiovascular system, Lymphatic system/immunity, Respiratory system, Digestive system, Urinary system, Male/Female Reproductive system
List the 11 organ systems of the body, identify their components, and briefly explain the major functions of each system.
Skeletal System
Protects and supports body organs, and provides a framework the muscles use to cause movement. blood cells are formed within bones. Bones store minerals.
Muscular System
Allows manipulation of the enviroment, locomotion, and facial expression. Maintains posture, and produces heat.
Nervous System
As the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands.
Endocrine System
Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells.
Cardiovascular System
blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, waste, etc. *The heart pumps the blood*
Lymphatic System/Immunity
Picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris in the _____ stream. Houses white blood cells _____ involved in immunity. The immune response mounts the attack against foreign substances within the body.
Respiratory system
Keeps blood constantly supplied with oxygen and removes carbon dioxide. The gaseous exchanges occur through the walls of the air sacs of the lungs.
Digestive system
Breaks down food into absorbable units that enter the blood for distribution to body cells. Indigestible foodstuffs are eliminated as feces.
Urinary system
Eliminates nitrogenous wastes from the body. Regulates water, electrolyte and acid-base balance of the blood.
Reproductive system
system of organs involved in producing offspring
List the 11 organ systems of the body, identify their components, and briefly explain the major functions of each system.
