Topic 3: Content

QuestionAnswer
The levels of organization (simplest to most complex) cells, tissues, organs, organ systems, organism
If its structure is more complex, then its function will be more complex
The circulatory system transports nutrients and other life-sustaining resources like oxygen
The circulatory system includes the heart, blood vessels, and blood cells.
The respiratory system brings air containing oxygen into your body and removes carbon dioxide and water
The main organs in the respiratory system are the lungs
The digestive system breaks down food and absorbs nutrients
The organs in the digestive system include the mouth, esophagus, stomach, small and large intestines.
The skeletal system supports the body, protects internal organs (ribs protect the heart/skull protects the brain), stores minerals, and produces red blood cells.
The main organs in the skeletal system are the bones
The muscular system works closely with the skeletal system to move the bones to move the body
The main organs of the muscular system are the muscles
The control system(s) include the nervous system
The Structural system(s) include Skeletal System and Muscular System
The Oxygen and Transport system(s) include Respiratory System and Circulatory System
The Food Processing system(s) include Digestive System
The nervous system receives information about what is happening inside and outside your body and directs your body's response. Your senses become sharper when your nervous system responds to sudden stress.
The nervous system includes the brain, spinal cord, and nerve cells
The spinal cord is a thick column of nervous tissue that connects the brain to the body’s nerves
All the systems in the human body work together to perform the functions for life
The condition in which an organism's internal environment is kept stable in spite of changes in the outside environment is called homeostasis
Some examples of ways to maintain homeostasis Your body can regulate temperature by shivering or sweating. Your body has to manage stress. Stress is the reaction to a threatening, challenging, or disturbing event. Your body has to fight diseases.
Interactions between the skeletal, muscular, and nervous systems provide the mechanism for movement
Eyes, ears, skin, nose, and taste buds send information to your nervous system, which controls body functions and movement.
A stimulus is a signal that triggers a response, or change in behavior
Blood cells in the circulatory system carry nutrients from the digestive system and oxygen from the respiratory system to the cells in your body
Blood cells also carry waste (CO2) from the body cells to the respiratory system to exhale out of the body
Stress is the reaction to a threatening, challenging, or disturbing event
