The human body consists of these four tissue types. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. Examples of human organs include the brain, heart, lungs, skin, and kidneys. 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, At each higher level of organization, there is a greater degree of complexity. Molecules are the chemical building blocks of all body structures. For example, one of the most important functions of organ systems is to provide cells with oxygen and nutrients and to remove toxic waste products such as carbon dioxide. In fact, most organs contribute to more than one system. Q. Defend against infection and disease, moves lymph between tissues and the blood stream.

Many people have compared the human body to a machine. Life processes of the human body are maintained at several levels of structural organization. In this book and throughout your studies of biological sciences, you will often read descriptions related to similarities and differences among biological structures, processes, and health related to a person's biological sex. You cannot download interactives. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of which are hydrogen, oxygen, carbon, nitrogen, calcium, and iron. Each cell carries out basic life processes that allow the body to survive. 1). Sarah Appleton, National Geographic Society.

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. Explain how form and function are related in human cells.

After tissues, organs are the next level of organization of the human body. These four tissue types, which are shown in Figure below, make up all the organs of the human body. 1) A. In multicellular organisms, including humans, all cells, tissues, organs, and organ systems of the body work together to maintain the life and health of the organism. The smallest unit of any of these pure substances (elements) is an atom. Throughout this book, "female" and "male" refer to sex only, and the typical anatomy and physiology of XX and XY individuals is discussed. After tissues, organs are the next level of organization of the human body. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things.

Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. Thus, the heart is an organ composed of all four tissues, whose function is to pump blood throughout the body. Think about some common machines, such as drills and washing machines. The female ovaries and the male testes are a part of which body system? The female ovaries and the male testes are parts of the reproductive system. Atoms are made up of subatomic particles such as the proton, electron and neutron. After cells, the next level of organization is tissues. An organ is a structure that consists of two or more types of tissues that work together to do Assigning organs to organ systems can be imprecise since organs that belong to one system can also have functions integral to another system. Each organ performs one or more specific physiological functions. The 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. In total, there are eleven organ systems in the body. Your organ systems do not work alone in your body.
