The coronary system is comprised of arteries, arterioles, capillaries, venules and veins. The coronary arteries originate as the right and left main coronary

2.2 Distributing Arteries The distributing arteries are also known as muscular arteries, because their thick media are made up almost entirely from smooth muscle cells. These arteries are smaller than the conducting arteries, with diameters in the range of about 1cm to 500 m. In the largest of the distributing arteries, there may be 30 or more

Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart. Small branches dive into the heart muscle to When the coronary arteries narrow to the point that blood flow to the heart muscle is limited (coronary artery disease), collateral vessels may enlarge and become active. This allows blood to flow around the blocked artery to another artery nearby or to the same artery past the blockage, protecting the heart tissue from injury.

the venules. distributing system with extensive anastomoses which provide for good collateral circulation 1 -"~. The three distributing arteries are tile anterior tibial, posterior tibial and peroneal arteries ( Figure 1 ). The posterior tibial artery is the larger terminal branch of tile popliteal artery. Any of the arteries that are branches of the vertebral, deep cervical, ascending cervical, inferior thyroid, posterior intercostal, lumbar, or lateral sacral arteries and that enter the vertebral canal through the intervertebral foramina to divide and then to join the posterior and anterior spinal arteries. Distributing arteries (or muscular arteries) are medium-sized arteries that draw blood from an elastic artery and branch into "resistance vessels" including small arteries and arterioles.

Muscular arteries are also called distributing arteries; these medium-sized vessels draw blood from the elastic arteries and distribute them to the smaller vessels. The femoral and coronary arteries are examples of muscular arteries. The walls consist of large amounts of smooth muscle, allowing them to contract and dilate.

Unlike elastic arteries, the elastic fibers in muscular arteries are The arteries that are also called distributing arteries are the ______. A) elastic arteries B) muscular arteries C) arterioles D) capillaries, B) muscular arteries. Arteries originating from the subclavian or axillary arteries and distributing to the anterior thoracic wall, mediastinal structures, diaphragm, pectoral muscles, Arteries arising from the external carotid or the maxillary artery and distributing to the temporal region. Arteries arising from the external carotid or the maxillary artery and distributing to the temporal region.

ABSTRACT The branching characteristics of the right coronary artery, acute marginal, posterior descending, left anterior descending, circumflex, and obtuse.

They draw blood from elastic arteries and branch into resistance vessels. These vessels include small arteries and arterioles. Arterioles are the In turn, muscular arteries branch to distribute blood to the vast network of arterioles. For this reason, a muscular artery is also known as a distributing artery. MUSCULAR (DISTRIBUTING) ARTERIES In muscular arteries, smooth muscle becomes the predominant constituent of the tunica media.

- network between the arteries and veins - involved in gas, nutrient and waste exchange Mean Arterial Pressure. As blood is pumped out of the left ventricle into the aorta and distributing arteries, pressure is generated. The mean arterial pressure (MAP) is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP) according to the following relationship, which is based upon the The human arterial system in youth is beautifully designed for its role of receiving spurts of blood from the left ventricle and distributing this as steady flow through peripheral capillaries.
