HCB TEST 10 CERTIFICATION EVALUATION
EXAMS COMPLETE QUESTIONS AND
ANSWERS PRACTICE SOLUTION
⩥ pulmonary circulation.
Answer: 1. deoxygenated blood from the upper body drain in the
superior vena cava and blood from the lower body drain in the inferior
vena cava which go to the right atrium
2. blood from the right atrium flows through the tricuspid valve to the
right ventricle
3. the right ventricle contracts causing the tricuspid valve to close and
the pulmonary valve to open
4. blood flows through the pulmonary valve passing through the
pulmonary artery to the lungs where it will be oxygenated
⩥ systemic circulation.
Answer: 1. left atrium receives oxygenated blood from the lungs via
pulmonary veins
2. blood from the left atrium flows through the mitral valve to the left
ventricle
3. the left ventricle contracts causing the mitral valve to close and the
aortic valve to open
4. blood flows through the aortic valve passing through the aorta to the
rest of the body
,⩥ coronary circulation.
Answer: circulation of blood through the coronary blood vessels to
deliver oxygen and nutrients to the heart muscle tissue then the
deoxygenated blood flows to the right atrium through the coronary sinus
⩥ what are the components of the conduction system?.
Answer: Sinoatrial node (SA), Atrioventricular node (AV), Bundle of
His (AV bundle), Right and left bundle branches, Purkinje fibers
⩥ what does a cardiac cycle consist of?.
Answer: systole and diastole of both atria and ventricles
⩥ Where does the sound of the heartbeat come from?.
Answer: turbulence in blood flow caused by the closure of the valves,
not from the contraction of the heart muscle
⩥ What is the first heart sound?.
Answer: (lub) created by blood turbulence associated with the closing of
the atrioventricular valves soon after ventricular systole begins (S1 on
SOAP note)
⩥ what is the second heart sound?.
, Answer: (dub) closing of the semilunar valves close to the end of
ventricular systole (S2 on SOAP note)
⩥ when is a pulse formed?.
Answer: When left ventricle contracts, sending a wave of blood through
the arteries
⩥ peripheral pulses.
Answer: the radial, brachial, posterior tibial, and dorsalis pedis pulses,
which can be felt at outer points of the body
⩥ central pusles.
Answer: the carotid and femoral pulses, which can be felt in the central
part of the body
⩥ How much of the body is made up of water?.
Answer: 60%
⩥ What spaces is water divided among in the body?.
Answer: intracellular, intravascular, and interstitial
⩥ intracellular.
Answer: water inside cells (70%)
