the human body
2. chemical level The chemical level is the most basic level of structural organi-
zation.
3. Atom 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.
4. Molecule A group of atoms bonded together - in the chemical level
5. cellular level The sum of the chemical reactions in a cell makes up its struc-
ture and function.
6. Organelles A tiny cell structure that carries out a specific function within the
cell
7. tissue level Groups of cells form tissues
8. There are four basic types of epithelial tissue
tissue grouped together by connective tissue
common features of structure muscular tissue
and function nervous tissue
9. The function of tissue is influ- by its constituent cells but also by the material and connections
enced by inside and outside of the cell.
10. organ level Organs are made up of different types of tissues
11. system level related organs with a common function
12. · organism level Any living thing, and is made up of 11 body systems.

13. integumentary system Consists of the skin, mucous membranes, hair, and nail
14. integumentary system func- Protects the body from the external environment, excretes
tions metabolic waste, helps to make vitamin D, and detects pain,
touch, dehydration, and changes in temperature.
15. Skeletal System the skeletal system consists of the bones and the cartilage
associated with joints.
16. skeletal system functions Protects the body, provides support and a framework for mus-
cles to act upon, contains bone marrow for blood cells to
develop in, and stores minerals such as calcium.
17. Muscular System 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, in-
cluding the alimentary canal and the walls of blood vessels.
18. Muscular system function Enables the body to move by the action of opposing muscular
contraction and relaxation. It also maintains posture and plays
a role in thermoregulation.
19. cardiac muscle an involuntary, striated muscle that makes up the walls of the
heart
20. smooth muscle a muscle found in viscera
21. Nervous System The nervous system includes the brain, spinal cord, nerves, and
special sense organs (e.g., eyes, ears, and taste buds). This
system is divided into the central nervous system, containing
the brain and spinal cord, and the peripheral nervous system,
containing everything else.
22. nervous system functions

The functionality of the nervous system can be split into three
main stages:
Detecting changes in the internal and external environment,
encoding them into electrical impulses, and transmitting them
along the nerves.
Processing electrical impulses and making decisions, either
consciously or unconsciously.
Activating muscles or glands to induce an appropriate re-
sponse to the initial stimulus.
23. Endocrine System The endocrine system consists of endocrine organs and en-
docrine tissue embedded within organs. Endocrine organs
include the pituitary, thyroid, pineal, parathyroid, and adrenal
glands. Endocrine tissue is also found within the hypothal-
amus, pancreas, thymus, gonads, heart, stomach, and small
intestine.
24. endocrine system function Hormones alter the metabolism of target cells. The hormone
can be very specific, affecting only one cell type, or very general,
affecting many cell types.
25. Cardiovascular System The cardiovascular system consists of the blood, heart, and
blood vessels.
26. Cardiovascular System func- Pumps blood around the body through the blood vessels to
tion deliver oxygen and nutrients to cells and remove metabolic
waste from cells. Regulates the water content of body fluids,
the acid-base balance, and the temperature of the body.
27. lymphatic system The lymphatic system consists of lymphatic fluid (lymph), lym-
phatic vessels, lymph nodes, the spleen, lymph nodules, and
thymus.
