Your lungs are the two organs inside your chest which fill with air when you breathe in.
e.g. I opened the window and filled my lungs with cool fresh air.
e.g. Water had entered his lungs and he was choking.
e.g. Your heart and lungs have to work harder if you’re overweight.
Your liver is a large organ in your body which processes your blood and helps to clean unwanted substances out of it.
e.g. Two weeks ago, it was discovered the cancer had spread to his liver.
e.g. a nationwide appeal for a donor liver
Your stomach is the organ inside your body where food is digested before it moves into the intestines.
e.g. It’s not a good idea to drink (= alcohol) on an empty stomach.
e.g. I was hungry and my stomach had started growling/rumbling (= making noises).
e.g. Jane was asked to lie down on her stomach.
Your intestines are the tubes in your body between the stomach and the anus. Food passes from the stomach to the small intestine and from there to the large intestine.
e.g. Antibodies from the mother’s milk line the baby’s intestines and prevent infection.
Your kidneys are the organs in your body that take waste matter from your blood and send it out of your body as urine.
e.g. Andy was recovering from a kidney transplant operation.
