Answer 8

The heart takes in oxygen from the environment and delivers it to cells. "
this is C

& no, heart doesnt take oxygen from the environment and delivers it to cells
its your respiratory system that does it, in other words you nose, trachea, larynx, pharynx, bronchi, bronchiole and alveoli
in short you lungs do it
not your heart
all your heart does is 'pump the blood' around your body by its beating

Answer 9

this pumping generates circulation of blood around your body & as it goes to your lungs region, the blood gets oxygenated, and comes back to heart and gets pumped out from left ventricle to the aorta which branches to more vessels and transports this oxygenated blood to all cells in the body

Answer 10

so you originally were correct (if that 3 stars shows the option you originally chose)
