Explanation:
Like plants, animals also need food for their bodies. But they can't produce their own food. They have to depend on others for food purposes. After eating anything, that don' t go their cells directly. It passes many stages; then, they go the cell as a fuel. From eating to consuming by the cell, many digestive processes happen, such as the degradation of larger molecules to small molecules. Many chemical reactions also occur to covert elements to that form, which can be taken by cells as fuel as the reaction in mitochondria.
This way, men and animals get food as their fuel.
<span>Hippocrates believed that there are four humors in human body which need balance for a healthy being. These were:
Blood, phlegm, yellow bile, and black bile.</span>
Galen expanded the idea of the humors and introduced four temperaments which were these:
choleric (hot / dry), melancholic (cold / dry), sanguine (warm / moist), and phlegmatic (cold / moist).
Another expansion Galen did was that he gave each humor/temperament physical and psychological qualities and said that even the food items have an association with the certain humor, those foods can effect certain humor in certain ways.
