What is occurring within the heart during each part of the EKG?
- ANSWER-At
the P wave of the EKG, the atria are
depolarizing.
At the QRS complex, the ventricles are depolarizing and
the atria are
repolarizing.
At the T wave, the ventricles are repolarizing and there is a
brief refractory
period between the T wave and the following P wave, which
allows the heart a
small rest.
Describe what is happening in the heart during atrial
systole/ventricular diastole
and atrial diastole/ventricular systole - ANSWER-Atrial
systole/ventricular
diastole - atria are contracting and ventricles
are relaxed
Atrial diastole/ventricular systole - atria are relaxed and
ventricles are
,contracting
How are the heart sounds made? - ANSWER-The first heart
sound "lubb" occurs during ventricular systole as a result of
the A-V valves closing. The second heart sound "dupp"
occurs during ventricular diastole as a result of the pulmonary
and aortic semilunar valves closing.
What terms are used to describe abnormal heart rhythms? -
ANSWER-
Arrhythmia, atrial fibrillation, bradycardia, tachycardia,
defibrillation, cardiac arrest, palpitations, Supraventricular
tachycardia (SVT), Ventricular tachycardia, and ventricular
fibrillation.
pulmonary circulation - ANSWER-Circulation of blood
between the heart and
the lungs, oxygenating blood and removing
carbon dioxide
coronary circulation - ANSWER-circulation of blood through
the coronary blood
vessels to deliver oxygen and nutrients to the heart
muscle tissue
systemic circulation - ANSWER-flow of blood from body tissue
to the heart and
then from the heart back to body
tissues
,What factors can influence heart rate and/or blood
pressure? – ANSWER-Cardiac output, blood volume,
peripheral resistance, and blood viscosity. As blood
volume, heart rate, stroke volume, blood viscosity, and
peripheral resistance increase, BP increases.
How is cardiac output figured? - ANSWER-Stroke volume
multiplied by the heart rate, expressed in bpm. (For example, if
the stroke volume is 70 mL, and the heart rate is 72 bpm, the
cardiac output is 5,040 mL per minute.
Where can pulse be found in the body? - ANSWER-The temple
(temporal a.), neck (carotid a.), chin (facial a.), inner elbow
(brachial a.), wrist (radial a.), groin (femoral a.), back of the
knee (popliteal a.), front of the foot (dorsalis pedis a.), back of
the ankle (posterior tibial a.)
At any given moment, where can blood be found in the body? -
ANSWER-Veins
major arteries of the body - ANSWER-temporal, carotid,
brachial, ulnar, radial,
femoral, popliteal, dorsalis pedis,
posterior tibial
major veins of the body - ANSWER-Superior and inferior vena
cava, right and left external and internal jugular and subclavian
v, right and left brachiocephalic v, hepatic v, splenic v, right
, and left common iliac v, external and internal iliac v, femoral v,
great saphenous v, small saphenous v
What is arteriosclerosis? - ANSWER-the thickening and
hardening of the walls
of the
arteries
How does aging affect the cardiovascular system? - ANSWER-
Cholesterol deposition happens in the blood vessels, the heart
enlarges, cardiac muscle cells die, there is an increase in
fibrous connective tissue, adipose tissue and blood pressure
and a decrease in resting heart rate.
What is the function of lymph? - ANSWER-To absorb dietary
fats, deliver fats
and excess fluids to the bloodstream, collect excess
interstitial fluids, and
deliver foreign particles to the
lymph nodes.
Describe a lymphatic vessel - ANSWER-Fine, thin-walled,
transparent valved channels distributed through most tissues.
They have 3 walls: intima, media, and adventitia.
Describe the pathway of lymph - ANSWER-Lymphatic
capillaries
Lymphatic vessels
Afferent lymphatic vessel
Lymph nodes
