Are the digestive system and skeletal are made of cells?

Yes, the digestive system and skeletal system, like all other systems in the body, are made up of cells. Cells are the basic unit of life and form the building blocks of all living things, including humans. The digestive system consists of various organs such as the mouth, esophagus, stomach, intestines, etc., which are all composed of different types of cells. For example, the lining of the esophagus is made up of epithelial cells, and the muscles responsible for the movement of food through the digestive tract are made of muscle cells. Similarly, the skeletal system, which provides support and protection for the body, is composed of specialized cells such as osteocytes, osteoblasts, and osteoclasts. These cells are involved in the synthesis and remodeling of bone tissue and the maintenance of calcium homeostasis. Therefore, both the digestive system and skeletal system consist of various types of cells that perform specific functions to ensure their proper functioning and overall health of the individual.
