Answer 1

Answer:

all

Explanation:

runnning is the most common way to improve your overall health, so it improves your organs:

heart= fat drops, reduces cholesterol, reduces production and stress hormones (adrenalin and cortisol), improves blood circulation, lowers risk of thrombosis, increases blood volume in your body.

lung=increases endurance capacity, improves diaphragm and intercostal muscles allowing better breaths, growing more capillaries can help have oxygen to your muscles quickee which basically gives you more energy and so it also removes toxins faster, toxins like carbon dioxide are removed faster after running, it so improves your lungs by making it cleaner.

new capillaries= makes muscles get nutrients and oxygen faster.

so 4: all is the answer
