heart / Liver /hati / 心脏 / 肝脏

When we talk about heart in English: good heart 心地善良; broken heart 伤心, our imagination will lead to this :

The same things happened when we talked in Malays Language : baik hati 好心, sakit hati 心痛。

Actually, what does a heart ( jantung ) looks like?

Your heart is about the same size as a pear. It sits behind your sternum (which is the bone between the two sides of your ribs) and your ribs on the left side of your body just next to your sternum.

The heart pumps blood around the body to all of the organs, muscles and other parts of the body. The blood carries oxygen and nutrients which the body needs to work properly, and it also carries waste products that we do not need away from the muscles and organs.

By the way, what does a “hati” (liver) looks like?

It looks like a reddish brown wedge.It lies on the right hand side of your abdominal cavity underneath the diaphragm and behind the ribs.

Liver makes glucose from carbohydrates . Some of this glucose travels in the blood to the rest of the body where it is used for energy. Some of the glucose is stored in the liver as glycogen and it is there until your body needs to use extra energy. It also helps to keep blood glucose at the right levels. Our liver makes bile then stores it in the gall bladder until the body needs some to digest fats.
