ACCURATE ANSWERS
What are the most abundant elements of the human body?-correct answerCarbon, Hydrogen, Oxygen,
Nitrogen
90% of the human body is composed of just four elements which are:-correct answerCarbon, Hydrogen,
Oxygen, Nitrogen
The smallest unit of an element that still retains the chemical and physical properties of the element is
called:-correct answerAtom
Subatomic particles are:-correct answerProtons (positive), Neutrons (neutral) and Electrons (negative)
All matter is composed of basic substances called-correct answerElements
An atom that tells you how many protons an atom has is called:-correct answerAtomic Number
The number of protons and neutrons is called:-correct answerMass Number
What is isotope?-correct answerThe 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?-correct answerAtom whose nucleus undergoes degeneration and in the
process gives off radiation
What is a molecule?-correct answerAtoms bonded together to form a chemical unit
What is a compound?-correct answerCombining different atoms
,What is ionic bond?-correct answerIons with opposite charges attract
What are ions?-correct answerParticle that is electrically charged because it has gained or lost one or
more eletrons
What is a covalent bonds?-correct answerAtoms sharing electrons instead of losing or gain them
What is polar bond?-correct answerBond created when electrons shared by adjacent atoms are shared
unequally
hydrophilic means-correct answerwater-living
Hydrophobic means-correct answerwater-fearing
What is electrolyte?-correct answerSubstances that release ions when puts into water
What is pH?-correct answera measure of hydrogen ion concentration
Anterior position-correct answera body part is located towards the front (ventral)
Posterior position-correct answera body part is located toward the back. (dorsal)
Superior position-correct answera body part is located ABOVE another part or towards the head
Anatomy-correct answerstructure as well as its relationship with other structure
Physiology-correct answerfunction of the body
,Proximal-correct answera body part is CLOSER to a specific point of origin or attachment or closer to the
trunk of the body
Distal-correct answera body part is FARTHER from the specific point of the origin or attachment
Superficial -external-correct answera body part is located near the surface
Deep (internal)-correct answera body part is located away from the surface
A sagittal plane (median) cuts the body-correct answerright down the middle
A frontal plane (coronal) is perpendicular (oppose) so it cuts the body-correct answerfrom ear to ear,
from shoulder to shoulder across
A transverse plane cuts the body-correct answerfrom the navel in half dividing the superior from the
inferior
A group of similar types of cells that performs a specific function is a(n):-correct answerTissue
What is the mechanism called which brings about an increasing change in the same direction? Example:
child birth-correct answerpositive feedback
The relative consistency of the body's internal environment is called-correct answerhemostasis
A group of similar types of cells that performs a specific function is a(n):-correct answertissue
A group of two or more types of tissues is a(n):-correct answerOrgan
Structures found WITHIN a cell that perform specific functions are:-correct answerOrganelles
, Place the levels of organization in order from least complex to most complex-correct answeratom,
molecule, organelle, cell, tissue, organ, organ system, organism
The mitochondrion is an example of a(an)-correct answerOrganelle
The nose is _ to the chin-correct answerSuperior
The muscles are _ to the skin-correct answerDeep
The sternum is anterior or to the heart.-correct answerVentral
What is the scientific term for the mouth-correct answerOral
Identify the plane that would divide the body into left and right sides-correct answerSagittal
The plane that divides a body part into anterior and posterior sections is the plane-correct
answerFrontal (coronal) plane
The cavity that contains the pleural and abdominopelvic cavities is the cavity-correct answerAnterior
(ventral)
The cavity that contains the pericardial and pleural cavities is the cavity.-correct answerVentral and
thoracic
The vertebral canal and cranial cavity is located within the cavity-correct answerPosterior, dorsal cavity
The serous membrane that lines the thoracic cavity is the-correct answervisceral pleura
The serous membrane covering the heart is the-correct answerParietal pericardium
