It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere (Figure 1). A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. Atoms are made up of subatomic particles such as the proton, electron and neutron. intestine. This is when similar types of cells come together to form tissue in the body. The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems. The cells are involved in the formation of different types of tissues that further constitutes the organ and organ systems in humans. Higher levels of organization are built from lower levels. The epithelial tissue can be classified into simple and compound epithelial tissues. Figure1.3Levels of Structural Organization of the Human BodyThe organization of the body often is discussed in terms of six distinct levels of increasing complexity, from the smallest chemical building blocks to a unique human organism. These include the chemical, cellular, tissue, organ, organ system, and the organism level. Assigning organs to organ systems can be imprecise since organs that belong to one system can also have functions integral to another system.
Therefore it is not possible to exchange the materials like gases, nutrients, etc., simply by diffusion and hence require specific organs and organ systems for specific functions and thereby fulfill the needs of each and every cell of the body to its satisfactory level.

This book covers eleven distinct organ systems in the human body (Figure 1.4andFigure 1.5). A human cell typically consists of flexible membranes that enclose cytoplasm, a water-based cellular fluid, with a variety of tiny functioning units called organelles. Life processes of the human body are maintained at several levels of structural organization. The cellular level is considered when a variety of molecules combine to form the fluid and organelles of a body cell. To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms and molecules. Figure 2.
