Physiology of the
Coronary arteries

Cardiac muscle cells are branching, striated, generally uninucleate cells

Properties of Cardiac muscle fiber

Besides circulating blood, the blood vessels provide two important means of measuring vital health statistics: pulse and blood pressure.

The blood pressure in blood vessels is traditionally expressed in millimetres of mercury
In the arterial system, this is usually around 120 mmHg systolic (high pressure wave due to contraction of the heart) and 80 mmHg diastolic

Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient carried by the blood. In all arteries apart from the pulmonary artery, hemoglobin is highly saturated (95-100%) with oxygen.

Blood vessels do not actively engage in the transport of blood (they have no appreciable peristalsis), but arteries—and veins to a degree—can regulate their inner diameter by contraction of the muscular layer.

Large collecting vessels, such as the subclavian vein, the jugular vein, the renal vein and the iliac vein.
Venae cavae (the two largest veins, carry blood into the heart).

When blood vessels connect to form a region of diffuse vascular supply it is called an anastomosis (pl. anastomoses). Anastomoses provide critical alternative routes for blood to flow in case of blockages.

Capillaries consist of little more than a layer of endothelium and occasional connective tissue.

Activation of the sympathetic nervous system increases heart rate and contractility; parasympathetic activation decreases heart rate but has little effect on contractility.

Cardiac output = heart rate × stroke volume.
Stroke volume depends to a large extent on the degree of stretch of cardiac muscle by venous return.

Cardiac output, typically 5 L/min, is the amount of blood pumped out by each ventricle in 1 minute. Stroke volume is the amount of blood pumped out by a ventricle with each contraction.

At a normal heart rate of 75 beats/min, a cardiac cycle lasts 0.8 s. Pressure changes promote blood flow and valve opening and closing.

Normal heart sounds arise chiefly from turbulent blood flow during the closing of heart valves. Abnormal heart sounds, called murmurs, usually reflect valve problems.

The heart is innervated by the autonomic nervous system
Postganglionic fibers innervate the SA and AV nodes and the cardiac muscle fibers.

The SA node has the fastest rate of spontaneous depolarization and acts as the heart’s pacemaker; it sets the sinus rhythm. Defects in the intrinsic conduction system can cause arrhythmias, fibrillation, and heart block

The conduction system of the heart consists of the SA and AV nodes, the AV bundle and bundle branches, and the Purkinje fibers. This system coordinates the depolarization of the heart and ensures that the heart beats as a unit.

Cardiac muscle has abundant mitochondria and depends almost entirely on aerobic respiration to form ATP.

As in skeletal muscle, the membrane depolarization of contractile myocytes causes opening of sodium channels and sodium entry, which is responsible for the rising phase of the action potential curve.

The atrioventricular valves (tricuspid and mitral) prevent backflow into the atria when the ventricles are contracting; the pulmonary and aortic valves (semilunar valves) prevent backflow into the ventricles when the ventricles are relaxing.

Aorta (the largest artery, carries blood out of the heart)
Branches of the aorta, such as the carotid artery, the subclavian artery, the celiac trunk, the mesenteric arteries, the renal artery and the iliac artery.
Capillaries (the smallest blood vessels)

There are various kinds of blood vessels

Tunica intima (the thinnest layer)
Tunica media (the thickest layer in arteries):
Tunica adventitia: (the thickest layer in veins)

three layers
