Summary Introduction
To write:
The medical importance of the anatomoses in the coronary arterial system.
Introduction:
The heart is the central organ of the circulatory system. It consists of four chambers: two upper chambers or atria and two lower chambers or ventricles. Blood passes across a valve before parting each heart chamber.

A 50-year-old male patient arrives in the emergency department complaining of severe chest pain. He is taken to the cardiac cath lab for a coronary angiogram and left ventriculogram. The cardiologist discovers a lesion in the left main coronary artery branch and orders an immediate CABG.
1. Why does the location of this lesion make it more dangerous than lesions in other locations?
2. What does the acronym CABG stand for?
3. Assuming that the CABG is successful, what is the patient's postoperative prognosis?
4. Could the cardiologist perform an angioplasty to repair the lesion?
Illuminate the Truth Capillaries
Highlight the word or phrase that makes cach of the following statements true.
1. Capillaries (are)(are not) evenly distributed throughout the body.
2. The majority of the capillaries in skeletal muscles are (constantly filled with blood)(shut down during periods
of rest).
3. Capillaries (take up)(release) wastes, such as carbon dioxide and ammonia.
4. Water (flows into)(moves into and out of) capillaries.
5. In diffusion, substances move from areas of (greater)(lesser) to (greater)(lesser) concentration.
6. The concentration of oxygen within capillaries is (greater than)(less than) the concentration of oxygen in the
surrounding tissue fluid; therefore, oxygen diffuses (into)(out of) the capillaries.
7. (Osmosis) (Filtration) occurs close to the arterial side of the capillary bed, while (colloid osmotic
pressure)(diffusion) operates toward the venous side.
8. Of all the fluid filtered at the arterial end of the capillary bed. about (85%)(15%) is…

- Illuminate the Truth Stroke Volume Highlight the correct word in each of the following sentences. 1. (Preload)(Afterload) is the amount of tension, or stretch, in the ventricular muscle just before it contracts. 2. (Contractility)(Stroke volume) is the force with which ventricular ejection occurs. 3. Starling's law of the heart states that the more the ventricle is stretched-within limits-the (less)(more) forcefully it will contract. 4. The force against which the heart must work to eject its volume of blood is called the (cardiac output)(afterload). 5. Factors that affect contractility are called (chronotropic) (inotropic) agents. 6. Factors that affect heart rate are called (diastolic)(chronotropic) agents.arrow_forwardv.
