|---|---|---|---|---|---|
| The heart is composed of how many chambers? | Four
🗑
|
||||
| What parts of the heart receive blood from the great veins? | Left and right atria
🗑
|
||||
| Describe the atria in terms of wall thickness and number of muscle fibers? | Thin-walled; contains relatively few muscle fibers
🗑
|
||||
| Which is more muscular, the left ventricle or the right ventricle? | Left ventricle
🗑
|
||||
| Which pumps blood to the systemic circulation, the right ventricle or the left ventricle? | Left ventricle
🗑
|
||||
| What separate the ventricles of the heart? | Interventricular septum
🗑
|
||||
| Where does the blood return to the heart from systemic circulation? | Right atrium
🗑
|
||||
| Through which great vein does the blood return from the systemic circulation to the heart? | Vena cava
🗑
|
||||
| Which vena cava drains the head and upper extremities? | Superior vena cava
🗑
|
||||
| What does the superior vena cava drain? | Head and upper extremities
🗑
|
||||
| Which vena cava drains the viscera and lower extremities? | Inferior vena cava
🗑
|
||||
| What does the inferior vena cava drain? | Viscera and lower extremities
🗑
|
||||
| The viscera is drained by which vena cava? | Inferior vena cava
🗑
|
||||
| The head is drained by which vena cava? | Superior vena cava
🗑
|
||||
| What kind of blood flows into the right atrium? | Deoxygenated
🗑
|
||||
| What happens when the pressure in the vena cava exceeds the pressure in the right atrium? | Deoxygenated blood flows into the right atrium
🗑
|
||||
| What causes deoxygenated blood to flow into the right atrium? | Pressure in the vena cava exceeding the pressure in the right atrium
🗑
|
||||
| What happens when the pressure in the right atrium exceeds the pressure in the right ventricle? | The tricuspid valve opens and blood flows passively into the right ventricle.
🗑
|
||||
| What causes the tricuspid valve to open? | Pressure in the right atrium exceeding the pressure in the right ventricle
🗑
|
||||
| If 75% of the stroke volume is the blood flowing passively into the right ventricle, what forces the remaining blood into the right ventricle? | Right atrial contraction
🗑
|
||||
| Right atrial contraction forces remaining blood into the right ventricle. What percent of the stroke volume is this? | 25%
🗑
|
||||
| Where is the blood pumped from the right ventricle? | Through the pulmonary artery to the lungs
🗑
|
||||
| What forces the pulmonic valve to open? | Right ventricular contraction increasing right ventricular pressure
🗑
|
||||
| Deoxygenated blood flows from the ___________ through the pulmonary artery to the lungs. | Right ventricle
🗑
|
||||
| ___________ blood flows from the right ventricle through the pulmonary artery. | Deoxygenated
🗑
|
||||
| Deoxygenated blood flows from the right ventricle through the _____________. | Pulmonary artery
🗑
|
||||
| Which is the only artery that carries deoxygenated blood? | Pulmonary artery
🗑
|
||||
| Deoxygenated blood flows from the right ventricle through the pulmonary artery to the _________. | Lungs
🗑
|
||||
| _________ blood returns to the left atrium via the pulmonary veins. | Oxygenated
🗑
|
||||
| Oxygenated blood returns to the ________ via the pulmonary veins. | Left atrium
🗑
|
||||
| When the pressure in the __________ exceeds the pressure in the _________, the mitral valve opens. | Left atrium; left ventricle
🗑
|
||||
| The mitral valve opens when ________________. | The pressure in the left atrium excceds the pressure in the left ventricle.
🗑
|
||||
| What happnes when the pressure in the left atrium exceeds the pressure in the left ventricle? | The mitral valve opens and blood flows passively into the left ventricle.
🗑
|
||||
| What causes the mitral valve to open? | Pressure in the left atrium exceeding the pressure in the left ventricle
🗑
|
||||
| What percent of the stroke volume is blood flowing passively into the left ventricle upon opening of the mitral valve? | 75%
🗑
|
||||
| What causes the remaining blood in the left atrium to move into the left ventricle after the 75% passively flows into the left ventricle? | Contraction of the left atrium
🗑
|
||||
| Following the left ventricle, where is the blood pumped? | Into the aorta.
🗑
|
||||
| What causes the aortic valve to open? | Contraction of the left ventricular wall which increases the left ventricular pressure.
🗑
|
||||
| Blood flows from the left ventricle through the ______ to the systemic circulation. | Aorta
🗑
|
||||
| Blood flows from the left ventricle through the aorta to the _____________. | Systemic circulation
🗑
