Anatomy and Physiology Quiz (Cardiac)

A typical adult heart measures [blank_start]12.5[blank_end] cm ([blank_start]5[blank_end] in) from the attached base to the apex

The apex reached the fifth intercostal space approximately [blank_start]7.5[blank_end] cm ( [blank_start]3[blank_end] in) to the [blank_start]left[blank_end] of the midline

The apex is [blank_start]6[blank_end] cm ([blank_start]2.5[blank_end] in) thick

The heart is located near the [blank_start]anterior[blank_end] chest wall directly behind the [blank_start]sternum[blank_end]

[blank_start]Myocardium[blank_end] is the cardiac muscle tissue

The [blank_start]Left Ventricle[blank_end] is the thickest of all the heart chambers

The atrioventricular valve ( AV valve) is also known as the bicuspid or the [blank_start]mitral[blank_end] valve

Blood leaves the ventricle through the aortic semilunar valve and into the [blank_start]ascending aorta[blank_end]

The Left Circumflex Artery supplies the [blank_start]left atrium[blank_end] and the [blank_start]left ventricle[blank_end]

The Left Marginal Artery supplies the [blank_start]left ventricle[blank_end]

The direction of blood flow away from the heart and back again is 1. [blank_start]Arteries[blank_end] 2. [blank_start]Arterioles[blank_end] 3. [blank_start]Capillaries[blank_end] 4. [blank_start]Venules[blank_end] 5. [blank_start]Veins[blank_end]

[blank_start]Venules[blank_end] are thin-walled veins that receive blood from capillaries

The capillary beds have the greatest combined [blank_start]surface area[blank_end]

Systolic Pressure - peak blood pressure measured during ventricular [blank_start]systole[blank_end]

Diastolic Pressure- minimum blood pressure at the end of the ventricular [blank_start]diastole[blank_end]

The way to find [blank_start]Aortic Pulse Pressure[blank_end] is Systolic pressure - Diastolic pressure

[blank_start]Chemoreceptors[blank_end] respond to changes in carbon dioxide, oxygen, or pH levels in the blood and cerebrospinal fluid

[blank_start]Cardiac output[blank_end] is the amount of blood ejected by the left ventricle each minute

Oxygen saturation in the right chambers of the heart is [blank_start]75[blank_end] %

Oxygen saturation in the left chambers of the heart is [blank_start]95[blank_end] %

The sinoatrial node is known as the heart's natural [blank_start]pacemaker[blank_end]

A cardiac cycle consists of one period of [blank_start]systole[blank_end] and [blank_start]diastole[blank_end]

Preload indicates how much [blank_start]blood[blank_end] a ventricle contains

The inferior vena cava delivers blood to the right atrium from the rest of the ____________, ______________, and ________________

The intra-atrial septum separates the __________ and __________

There are 6 pulmonary veins

The Superior Vena Cava delivers blood to the right atria from the head, neck, upper limbs, and ____________

The Right Coronary Artery supplies the [blank_start]right atrium[blank_end] and the [blank_start]right ventricle[blank_end]

The Left Anterior Descending Artery supplies the ________________, _______________, and _____________

The Right Marginal Artery supplies the right ventricle and apex
