GUYS HOW MANY LEVEL OF ORGANIZATION DO WE HAVE?
Answers
Explanation:
Levels of Structural Organization of the Human Body. 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
The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

Answer:
The human body has 6 main levels of
structural organization.
1: Chemical level – is the simplest level within
the structural hierarchy. The chemical level
includes the tiniest building blocks of matter,
atoms , which combine to form molecules , like
water. In turn, molecules combine to form
organelles , the internal organs of a cell.
2: Cellular level – the cellular level is made up of
the smallest unit of living matter, the cell.
Individual cells may have some common
functions but vary widely in size and shape.
Each type of cells carries out a set of unique
tasks within the human body.
3: Tissue level – Tissues are groups of similar
cells that have a common function. A tissue
must contain two different types of cells. The
four basic tissue types in humans include
epithelium, connective, muscle, and nervous
tissue. Each tissue has a characteristic role
within the human body.
4: Organ level – an organ is a structure composed
of at least two different tissue types that
perform a specific function within the body.
Examples include the brain, stomach, and
liver. Complex functions begin to emerge at
this level.
5: Organ system level– One or more
organs work in unison to accomplish
a common purpose. For instance, the
heart and blood vessels work
together and circulate blood
throughout the body to provide
oxygen and nutrients to cells. Besides
the cardiovascular system, the other
organ systems of the body are the
integumentary, skeletal, nervous,
muscular, endocrine, respiratory,
lymphatic, digestive, urinary, and
reproductive systems.
6: Organismal level – The organismal
level is the highest level of
organization. It is the sum total of all
structural levels working together. In
short, it is the human being (or organism) as
a whole.
