Cardiovascular / (Circulatory) System

Functions of the Blood Carries oxygen from lungs to all body cells & removes carbon dioxide from the cells

Functions of the Blood Carries oxygen from lungs to all body cells & removes carbon dioxide from the cells Carries waste products of cell activity to kidneys to be removed from the body

Functions of the Blood Carries oxygen from lungs to all body cells & removes carbon dioxide from the cells Carries waste products of cell activity to kidneys to be removed from the body Transports nutrients from digestive system to body cells

Functions of the Blood Carries oxygen from lungs to all body cells & removes carbon dioxide from the cells Carries waste products of cell activity to kidneys to be removed from the body Transports nutrients from digestive system to body cells Materials in blood help fight infection and heal wounds (white blood cells & platelets)

Which is not a function of the cardiovascular system? Carry nutrients & oxygen to body cells Carry carbon dioxide & waste away from body cells Attack disease-causing bacteria Produce chemicals that control body processes 8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
