most of them are actually made of metal, cloth, rubber, leather and plastic Under non-living things, there are two groups: 1) Once Alive 2) Never Alive Once alive are things that are from alive things such as the skin of the snake used to make a handbag.

Limpic System
The endocrine system, particularly hormones such as leptin and ghrelin, plays a key role in regulating appetite by signaling hunger and fullness to the brain. Social factors, such as the companionship of others during meals, can also influence appetite through psychological and emotional mechanisms. Additionally, the brain's reward system, which involves neurotransmitters like dopamine, can be activated by consuming good food or engaging in enjoyable social interactions, further influencing appetite.
The limbic system, specifically the hypothalamus, is responsible for creating the sensation of appetite and motivating an individual to seek out food and social connections in order to maintain survival and well-being. It regulates hunger, thirst, and other basic biological needs.

Well, if your body is alive, all organs and tissues are alive. However, separate from the body, the digestive system would not function. Therefore, it cannot be said that the digestive system is "alive" apart from its functioning within the body.
The skeletal system receives a blood supply, just as every other system of the body does. Blood carries all the necessary oxygen, nutrients, and other things needed to support life.
