In order to use chemicals to regulate body systems this system is necessary.

• circulatory

• digestive

• endocrine

• muscular

These 2 systems work together to make the body move

• skeletal and muscular

• digestive and excretory

• nervous and endocrine

• circulatory and respiratory

this is the main organ of the nervous system

• brain

• heart

• lungs

• intestines

this system helps the body get rid of carbon dioxide and brings in oxygen.

• circulatory

• endocrine

• respiratory

• skeletal

this part of the plant and animal cell turns food into energy

• cytoplasm

• nucleus

• mitochondria

• cell membrane

this part of the excretory system filters waste from the blood

• kidneys

• bladder

• lungs

• heart

This part of the cell keeps all the organelles inside the cell and allows things into and out of the cell.

• cytoplasm

• liver

• cell membrane

• nucleus

These are the structures of the circulatory system that bring blood to and from the heart.

• arteries, capillaries and veins

• capillaries, liver and stomach

• veins, capillaries and kidneys

• pancreas, arteries and lungs

What is the main function of the excretory system?

• digest food that the cells can use

• bring nutrients to the cells

• remove waste from the body

• bring impulses to the brain.

This brings impulses from the nerves to the brain.

• from the gall bladder to the brain

• from the cns to the pns

• from the veins to the arteries

• peripheral nervous system to the central nervous system
