Human organs are built by tissues, which are in turn made up of cells. Cells are the basic building blocks of all living organisms and are organized into tissues to form organs. These organs work together within organ systems to carry out various functions in the body.
The human organism is a complex structure composed of many parts. Its major features include several body cavities, layers of membranes within these cavities, and a variety of organ systems.
The order of complexity begins with the cell as a functional unit. These cells work together to form tissues which work with other tissues to form organs. The organs work with other organs to form an organ system. The organ systems work all together to form a functioning organism.If you begin with a skeletal muscle cell and place many together that will make muscle tissues. Then add ligaments, tendons and bones (organs) to make the musculoskeletal system. This systems works with other systems in the body so that body will function naturally.
Human organs generally finish developing within the first few years of life, but some continue to grow and mature into adolescence and early adulthood. The brain, for example, is not fully developed until the mid-20s. However, organs like the heart and lungs are typically fully functional by early childhood.

Human anatomy is all about human organs and body systems.

cells, tissues, organs, organ systems, and organisms
The human body is made of organs. Certain organs work together to form systems. We each have a respiratory and a Circulatory system, Digestive system and Excretory System.

I think the human body needs organs because it coud'nt live without it
