Organs are composed of tissues. Tissues are composed of identical cells, which are then made of proteins, lipids, carbohydrates and nucleic acids.
proteins....
Most of the structural components of an organism is made from proteins. Connective tissues like collagen and adhesion structures are made of proteins, usually more than one per unit, to connect and hold an organism together and provide structure.
Proteins are the main building blocks for tissues including muscle, hair, nails, skin, eyes, internal organs, nerves, ligaments, tendons, cartilage and membranes. They are also the building blocks of cells, cellular membranes, organelles--all the way to the level of DNA and genes.
Cells are the building blocks of life.
Cells are the main building blocks of all tissues. Tissues are the building block of organs.

cells: the basic building blocks of life
Proteins are the main building blocks for tissues including muscle, hair, nails, skin, eyes, internal organs, nerves, ligaments, tendons, cartilage and membranes. They are also the building blocks of cells, cellular membranes, organelles--all the way to the level of DNA and genes.
Remember, amino acids are the building blocks of cells. Cells are the building blocks for tissues; cells specialize into specific types of tissues. Tissues built of specialized cells form organs. Single or multiple organs make organ systems. All of the organ systems make up the organism, the human body in this case. So the answer to this question is cells.
