Apex of the heart - ANSWER-tip of the heart pointing down toward the 5th left intercostal space
Which layer of the heart allows it to act as a pump? - ANSWER-Myocardium
Left ventricle - ANSWER-What is the hardest working cardiac chamber and therefore has the thickest
myocardium?

Which of the following contains oxygenated blood? - ANSWER-Pulmonary veins
Coronary arteries - ANSWER-Which of the following supplies oxygenated blood to the heart muscle?
Myocardium - ANSWER-Which layer of the heart has actin, myosin, and troponin?
coronary arteries. - ANSWER-What is the next step in the sequence of the blood flow: Blood flows from
the left atrium to the left ventricle to the aorta to which of the following structures?
Oxygen poor Carbon dioxide rich - ANSWER-Select all that apply >>>Which features are true of blood
leaving the tissues, travelling towards the right atrium?
, pulmonary capillaries. - ANSWER-What is the next step in the sequence of the blood flow: Blood flows
