What are the most Carbon, Hydrogen, Oxygen, Nitrogen
abundant elements of the
human body?
90% of the human body is Carbon, Hydrogen, Oxygen, Nitrogen
composed of just four
elements which are:
The smallest unit of an Atom
element that still retains the
chemical and physical
properties of the element is
called:
Subatomic particles are: Protons (positive), Neutrons (neutral) and Electrons
(negative)
All matter is composed of Elements
basic substances called
An atom that tells you how Atomic Number
many protons an atom has is
called:
The number of protons and Mass Number
neutrons is called:
,What is isotope? The same element but different number in protons and
neutrons-Mass Number (protons plus neutrons) minus
Atomic Number (number of protons) equals the number of
neutrons.
What is radioactive isotope? Atom whose nucleus undergoes degeneration and in the
process gives off radiation
What is a molecule? Atoms bonded together to form a chemical unit
What is a compound? Combining different atoms
What is ionic bond? Ions with opposite charges attract
What are ions? Particle that is electrically charged because it has gained or
lost one or more eletrons
What is a covalent bonds? Atoms sharing electrons instead of losing or gain them
What is polar bond? Bond created when electrons shared by adjacent atoms are
shared unequally
hydrophilic means water-living
Hydrophobic means water-fearing
What is electrolyte? Substances that release ions when puts into water
What is pH? a measure of hydrogen ion concentration
Anterior position a body part is located towards the front (ventral)
Posterior position a body part is located toward the back. (dorsal)
Superior position a body part is located ABOVE another part or towards the
head
Anatomy structure as well as its relationship with other structure
Physiology function of the body
a body part is CLOSER to a specific point of origin or attachment or
Proximal
closer to the trunk of the body
,Distal a body part is FARTHER from the specific point of the origin or
attachment
Superficial -external a body part is located near the surface
Deep (internal) a body part is located away from the surface
A sagittal plane (median) cuts right down the middle
the body
A frontal plane (coronal) is from ear to ear, from shoulder to shoulder across
perpendicular (oppose) so it
cuts the body
A transverse plane cuts the from the navel in half dividing the superior from the inferior
body
A group of similar types of Tissue
cells that performs a specific
function is a(n):
What is the mechanism positive feedback
called which brings about an
increasing change in the
same direction? Example:
child birth
The relative consistency of hemostasis
the body's internal
environment is called
A group of similar types of tissue
cells that performs a specific
function is a(n):
A group of two or more types Organ
of tissues is a(n):
Organelles
Structures found WITHIN a
cell that perform specific
functions are:
, Place the levels of atom, molecule, organelle, cell, tissue, organ, organ system,
organization in order from organism
least complex to most
complex
The mitochondrion is an Organelle
example of a(an)
The nose is _______ to the Superior
chin
The muscles are _____ to the Deep
skin
The sternum is anterior or Ventral
______ to the heart.
What is the scientific term for Oral
the mouth
Identify the plane that would Sagittal
divide the body into left and
right sides
The plane that divides a Frontal (coronal) plane
body part into anterior and
posterior sections is the
______ plane
The cavity that contains the Anterior (ventral)
pleural and abdominopelvic
cavities is
the ______ cavity
The cavity that contains the Ventral and thoracic
pericardial and pleural
cavities is the ______ cavity.
Posterior, dorsal cavity
The vertebral canal and
cranial cavity is located
within the ______ cavity
