(the body)
chemical level - ANSWER- The chemical level is the most basic level of
structural organization.
Atom - ANSWER- chemical elements that makes up the human body- in
the chemical level , Oxygen, carbon, hydrogen, and nitrogen make up
96% of the body's mass.
Molecule - ANSWER- A group of atoms bonded together - in the
chemical level
cellular level - ANSWER- The sum of the chemical reactions in a cell
makes up its structure and function.
Organelles - ANSWER- A tiny cell structure that carries out a specific
function within the cell

tissue level - ANSWER- Groups of cells form tissues
There are four basic types of tissue grouped together by common
features of structure and function - ANSWER- epithelial tissue
connective tissue
muscular tissue
nervous tissue
The function of tissue is influenced by - ANSWER- by its constituent
cells but also by the material and connections inside and outside of the
cell.
organ level - ANSWER- Organs are made up of different types of
tissues
system level - ANSWER- related organs with a common function
· organism level - ANSWER- Any living thing, and is made up of 11
body systems.
integumentary system - ANSWER- Consists of the skin, mucous
membranes, hair, and nail
, 3|Page
integumentary system functions - ANSWER- Protects the body from the
external environment, excretes metabolic waste, helps to make vitamin
D, and detects pain, touch, dehydration, and changes in temperature.
Skeletal System - ANSWER- the skeletal system consists of the bones
and the cartilage associated with joints.
skeletal system functions - ANSWER- Protects the body, provides
support and a framework for muscles to act upon, contains bone marrow
for blood cells to develop in, and stores minerals such as calcium.
Muscular System - ANSWER- The muscular system consists primarily
of skeletal muscle, but there are also two other types of muscle: cardiac
muscle found in the heart and smooth muscle found within the viscera,
including the alimentary canal and the walls of blood vessels.
Muscular system function - ANSWER- Enables the body to move by the
action of opposing muscular contraction and relaxation. It also maintains
posture and plays a role in thermoregulation.
cardiac muscle - ANSWER- an involuntary, striated muscle that makes
up the walls of the heart
smooth muscle - ANSWER- a muscle found in viscera
Nervous System - ANSWER- The nervous system includes the brain,
spinal cord, nerves, and special sense organs (e.g., eyes, ears, and taste
