🗑
|
||||
| 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 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
🗑
