1. Chapter 28:
2. The vascular system provides for: The delivery of oxygenated blood to the
tissues
• The removal and transportation of cellular waste for excretion
• The return of circulatory volume to the right heart
• The return of lymph fluid back into the general circulation
3. The arterial sequence of vessels is as follows:: arteries to arterioles to metar-
terioles to capillaries.
4. Left anterior descending (LAD) branch supplies blood to: Both ventricles and
Left anterior descending (LAD) branch
5. Circumflex branch branches from the left coronary artery and supplies
blood to: Anterior wall of the heart.
Left atrium
Posterior wall of the left ventricle
6. Right marginal branch branches from the right coronary artery and supplies
blood to: Lateral aspect of right atrium and ventricle
7. Posterior interventricular branch branches from the right coronary artey
and supplies blood to: Posterior aspect of both ventricles and interventricular
septum
8. The normal pacemaker, the sinoatrial (SA) node, has an inherent rate of 60
to 100 beats per minute (bpm). In the absence of an impulse from the SA node,
the atrioventricular (AV) node can generate impulses at rates of --- to --- bpm.
If the SA and AV nodes fail, ventricular cells can generate impulses at a rate
of ..... to --- bpm.: 40 to 60
20 to 40
9. Repetitive, uncontrolled muscular contractions are called: Tetany
