Which of the following is the correct order for the organization of the body

Describe, in order from most basic to the majority of complex, the significant levels of organization in the humale organism

All living and non-living points are made of one or even more distinct substances referred to as elements, the smallest unit of which is the atom, (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and also hydrogen (H) is made of H atoms. Atoms incorporate to develop molecules. Molecules can be little (for instance, O2, oxygen gas, which has 2 atoms of the aspect O; CO2, carbon dioxide, which has 1 atom of C and 2 of O), tool (for instance, C6H12O6, glucose, which has 6 atoms of C, 12 of H, and 6 of O); or large (for example molecules dubbed proteins are made of hundreds of atoms of C, H, and O through other elements such as nitrogen (N). Molecules are the structure blocks to all structures in the human body.

All living frameworks are made of cells, which are made of many kind of various molecules. Cells are the smallest independent living point in the huguy body. The body is made of many various cell types, each via a particular function, (for instance muscle cells contract to move something, and red blood cells bring oxygen). All human cells are made of a cell membrane (thin external layer) that encloses a jelly-choose cellular fluid containing tiny organ-likestructures dubbed organelles. There are many types of organelles, each through a specific attribute (for instance, organelles referred to as mitochondrion gives energy to a cell). Different forms of cells contain different quantities and also types of organelles, depending on their attribute, (for instance muscle cells use a lot of energy and therefore have many mitochondria while skin cells perform not and also have few mitochondria).

As in various other multicellular organisms, cells in the human body are organized right into tproblems. A tissue is a group of comparable cells that job-related together to perform a particular feature. Tright here are 4 primary tworry kinds in human beings (muscular, epithelial, nervous and connective). An organ is an identifiable structure of the body composed of two or more tissues forms (for instance, the stomach consists of muscular tissue made of muscle cells, which enables it to readjust its form, epithelial tissue which lines both the inner and also external surconfront of thestomach, nervous tissue which sends out and receives signals to and also from the stomach and also the main nervous device, and also connective tissue which binds whatever together). Organs often percreate a certain physiological attribute (for example, the stomach helps digest food). An organ system is a team of organs that work together to perdevelop a particular function (for instance, the stomach, tiny and also big intestines are all organs of the digestive system, that work together to digest foodstuff, relocate nutrients right into the blood and also eliminate waste). The the majority of facility level of organization, the huguy organism is composed of many type of organ units that work together to perdevelop the features of anindependent individual.

The major levels of organization in the body, from the most basic to the many complicated are: atoms, molecules, organelles, cells, tproblems, organs, body organ systems, and also the huguy organism. See listed below Figure (PageIndex1) .
