Chemical
The human body is made up of atoms. Oxygen, carbon, hydrogen, and nitrogen make up 96% of
the body's mass. There are 22 other elements that also commonly occur in the human body,
such as iron.
Atoms combine to form molecules, for example, water, glucose, and DNA
Cellular
The sum of the chemical reac ons in a cell makes up its structure and func on. O3en these
reac ons are confined to specific regions within a cell, known as organelles.
Tissue
There are four basic types of ssue grouped together by common features of structure and
func on:
epithelial ssue
connec ve ssue
, muscular ssue
nervous ssue
Organ
Organs have specific func ons
System
e systems have organs that are in direct physical contact and therefore func on together, such
as the organs of the diges ve system, but others are related by func onal or structural
similari es and do not have direct contact, such as the glands that form the endocrine system.
Organism
Each body system carries out its individual func ons, but all of these organ systems must work
together for the organism to operate as a whole.
organelles
any of several different types of membrane-enclosed specialized structures in the cell that
perform specific func ons for the cell
Integumentary System
The integumentary system consists of the skin and the associated skin components, such as hair,
sweat glands, sebaceous glands, and nails.
Integumentary System Func on
Protects the body from the external environment, excretes metabolic waste, helps to make
vitamin D, and detects pain, touch, dehydra on, and changes in temperature.
Skeletal System
The skeletal system consists of the bones and the car lage associated with joints.
Skeletal System Func on
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
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.
