The topic of Matsumi Ladies Clinic Mita English blog in March is about the mouth.

In the first part, I create an article from the medical perspective.

 

Anatomically, the mouth, also known as the oral cavity, is the opening through which most living things including insects, birds and animals take in food and produce vocal sounds.

The mouth is composed of the beak in birds and the lips with the tongue and teeth in animals.

 

In the first multicellular life things, there was probably no mouth and nutrients were absorbed by the cells from the exterior surface with a process known as endocytosis.

They become enclosed as capsules and digested with the secreted enzymes.

The digestive products were absorbed into the cytoplasm and diffused to other cells.

This form of digestion is still existing in the simple organisms such as Amoeba.

 

The mouth has other functions other than producing sounds and taking food.

The most important is the regulation of body temperature.

 

For example, crocodiles and hippos living in the tropics can open their mouth and cool down by evaporation from inside of the mouth.

 

The mouth is the most important facial part that determines the impression of facial expressions.

The second part, I will create an article focusing on lipsticks, especially on their colors.

 

Matsumi Ladies Clinic Mita has started handling lipsticks that are effective for anti-aging.
