Question | Answer |
The cardiovascular system consists of the following: | heart & blood vessels |
precordium | area on the anterior chest directly overlying the heart and great vessels |
great vessels | major arteries and veins connected to the heart |
The heart is found here | 2nd to 5th intercostal space; from the right border of the sternum to the left midclavicular line |
where can you palpate the apex | 5th intercostal space |
the functions of the superior and inferior vena cava is to | return unoxygenated venous blood to the right side of the heart. |
what is the difference between the function of the pulmonary artery and vein? | the pulmonary artery carries venous blood to the lungs from the right ventricle. the pulmonary vein returns oxygenated blood to the left side of the heart. |
aorta | carries the oxygenated blood to the rest of the body |
pericardium | tough, fibrous, double walled sac that surrounds and protects the heart. It has 2 layes and contains pericardial fluid to reduce friction and ensure smooth free movement of the heart |
atrium | holds the blood |
ventricle | muscular pumping chamber |
WHen do AV valves open? When do the close. | AV valves open during diastole (relaxing/ filling phase); AV valves close during systole (contracting). |
The tricuspid valve lies in the | right side of the heart |
the bicuspid valve lies in the | left side of the heart |
AV valves separate these structures | atrium and ventricle |
Semilunar valves seperate these structures | venticles and the arteries |
Semilunar valves: Right Left | Right: pulmonic valve Left: aortic |
Semilunar valves open during | systole to allow ejected from the heart |
There are no valves here: | between the vena cava and the right atrium; between the pulmonary veins and the left atrium |
High pressure in the left side of the heart | gives a person symptoms of pulmonary congestion |
Abnormally High pressure in the right side of the heart shows | in the neck veins and abdomen |
Direction of Blood flow | liver->RA->Inferior vena cava (superior drains venous blood from head and upper extremities).-> From RV, venous blood flows through pulmonic valve to pulmonary artery (Pulmonary artery delivers unoxygenated blood to the lungs). |
pulmonary veins return fresh blood | to the left atrium |
arterial Blood travels from the left atrium | through the mitral alve to the left ventricle |
Blood flows from an area of | higher concentration to lower concentration |
the pressure in atria | is higher than the pressure in ventricles |
early/ protodiastolic filling | first passive filling phase |
