Controls most functions in the body.
Skeleton
Immune System
Brain
Skin
Lungs
Small blood vessels where materials are exchanged between the blood and the body’s cells (oxygen and carbon dioxide)
Where the exchange of gas occurs. Oxygen enters and carbon dioxide exits.

the digestive system
the excretory system
the respiratory system
the cardiovascular system
The cardiovascular system is composed of blood vessels that travel from the heart to the rest of the body and back to the heart. Why does blood make a complete loop throughout the body?
Blood needs to circulate through my body to allow for my kidneys to absorb CO2
Blood needs to circulates through my body to provide signals to move the muscles
Blood needs to circulate through my entire body so it can transfer CO2 to all of the cells.
Blood needs to circulate through my entire body (to all of the cells in all of the systems) so that my body can maintain homeostasis.
The digestive system is responsible for breaking down food into nutrients, what other systems does it work with to help nutrients get to every cell in the body?
Cardiovascular system - absorbs nutrients into the bloodstream via capillaries in the small intestine.
Excretory system - absorbs nutrients into the bloodstream via the kidneys
Respiratory system - absorbs nutrients into the bloodstream via the alveoli in the lungs
Nervous system - absorbs nutrients into the bloodstream via neurons in the spinal cord
Describe the relationship between the muscular and respiratory system.
The diaphragm is a muscle which allows for the lungs to inhale and exhale as it expands and contracts.
The diaphragm is a muscle which sends messages for the lungs to inhale or exhale.
The diaphragm is a muscle which allows for absorption of O2 into the bloodstream.
The lungs are a muscle which allows for the diaphragm to expand and contract
When the excretory system is not working properly, what other system is directly affected?
The cardiovascular systems as the blood is cleaned by the kidneys of the excretory system.
The respiratory system as the blood is cleaned by the kidneys of the excretory system.
The immune system as the blood is cleaned by the kidneys of the excretory system.
