In what ways do the circulatory system and the lymphatic system work together to fight infection?

• Both systems have white blood cells (WBC) which will fight the infection.

• Both systems have red blood cells (RBC) which will fight the infection.

• Both systems have platelets which will fight the infection.

• Both systems have plasma which will fight the infection.

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.

How do the respiratory and cardiovascular systems work together to help cells obtain oxygen and remove waste?

• CO2 rich blood is diffusing out of the circulatory system (via capillaries surrounding alveoli into the lungs) to be exhaled while at the same time O2 is diffusing into the bloodstream.

• CO2 rich blood is diffusing out of the digestive system (via capillaries surrounding small intestine) to be exhaled from the lungs of the respiratory system

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.

• The digestive system as the blood is cleaned by the kidneys of the excretory system.
