In this unit, students explore the structures and functions of many of the human body systems. Specific emphasis is on how those body systems work together to perform important body functions for life.
Power standard: Describe how the human body systems’ functions are interlinked.
State Standard: 6.MS-LS1-3. Construct an argument supported by evidence that the body systems interact to carry out essential functions of life.
8.MS-LS1-7. Use informational text to describe that food molecules, including carbohydrates, proteins, and fats, are broken down and rearranged through chemical reactions forming new molecules that support cell growth and/or release of energy.
What are the structures and functions of each human body system?
How do the systems work together?
Human Body Matrix and Concept Map
Human Body Systems
Skeletal system: supports and protects soft tissues of the body; produces blood cells; stores minerals. Structures: Bones, cartilage; ligaments
Muscular system: permits movement of the body, maintains posture and circulates blood throughout the body. Structures: skeletal, smooth and cardiac muscles
Cardiovascular system: Transports oxygen, hormones, and nutrients to the body cells. Moves wastes and carbon dioxide away from cells. Structures: heart, veins, arteries, blood
Respiratory system: brings air to sites where gas exchange can occur between the blood and cells or blood and air. Structures: alveoli, trachea, larynx, pharynx, lungs
Digestive system: breaks down foods and absorbs nutrients, minerals, vitamins, and water. Structures: esophagus, stomach, small intestine, large intestine
Nervous system: Collects, transfers, and processes information. Structures: brain, spinal cord, nerves, neurons
