TEAS 6 Science Exam
, TEAS 6 Science Exam Questions with
100% Correct Answers | Graded A+
Muscles involved in inhalation and do they expand or contract? -
✔✔Intercostals and diaphragm contract
Part of brain that monitors CO2 to regulate breathing - ✔✔Medulla oblongata
Two main functions of nucleolus - ✔✔Protein synthesis, synthesis and storage
of RNA
Function of ribosomes - ✔✔Synthesize proteins from RNA
Golgi complex function - ✔✔Synthesizes materials such as proteins that are
transported out of the cell
Endoplasmic reticulum - ✔✔transport system of cell
Mitochondria functions - ✔✔Production of cell energy; cell signaling; cellular
differentiation; cell cycle and growth regulation
Events of prophase - ✔✔chromatin thickens into chromosomes; nuclear
membrane begins to disintegrate; pairs of centrioles move to opp sides of cell
and spindle fibers form; mitotic spindle starts to move chromosomes around

, Connective tissue - ✔✔bone, cartilage, tendons, ligaments, fat, blood, lymph
Hyperventilation does what to pH? - ✔✔Increases blood pH during acidosis;
slowing breathing during alkalosis will decrease pH
How much blood in adult human? - ✔✔5 L/quarts
Composition of blood - ✔✔...
Cardiac cycle - ✔✔First diastole: blood flows from sup and inf vena cavae to
right atrium through open AV/tricuspid valve. SA node of right atrium contracts
to fill R ventricle w blood. Impulse transmitted through AV node, R ventricle
contracts and initiates first systole. Tricuspid valve closes, pulmonary semilunar
opens. Blood pumped from pulmonary arteries to lungs. Blood from lungs fills L
atrium during second diastole. SA node triggers mitral valve to open, blood fills
left ventricle. During second systole, mitral valve closes and L ventricle
contracts, blood pumped from aorta to rest of body.
Lymph vascular system functions - ✔✔Return of excess fluid to blood; return of
proteins from capillaries; transport of fats from digestive tract; disposal of
debris and cellular waste
Thymus functions - ✔✔Thymosin promotes Tcell formation, T cells mature here
