Answer:
Food is broken down into smaller molecules called nutrients. This process is called digestion. Chemical, energy is stored in the bonds between the molecules that make up food. When the body is active, the energy from food is transformed into heat. This energy is measured in calories
Explanation:
Once the food is in our body, we digest it, that is to say, that we break it down to obtain nutrients that the body can absorb. From this process, we obtain amino acids, lipids, and carbohydrates, which are macromolecules that store energy in their bonds. That is why they store chemical energy. When our body is active and needs energy, it will break these chemical bonds and obtain energy. The chemical energy becomes heat, which is the energy that the body can use. We measure this energy in calories.

<span>The dermis or corium is a layer of skin between the epidermis and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain. It is divided into two layers, the superficial area adjacent to the epidermis called the papillary region and a deep thicker area known as the reticular dermis. The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix. It also contains mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat. In addition, hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels and blood vessels are present in the dermis. Those blood vessels provide nourishment and waste removal for both dermal and epidermal cells.</span>
