Arteries anatomy. Arteries are components of the cardiovascular system. The left main coronary artery supplies blood to the left side of the heart muscle the left ventricle and left atrium. In elastic arteries the tunica media is rich with elastic and connective tissue.

The media a layer of muscle that lets arteries handle the high pressures from the heart. These arteries divide into progressively smaller branches. The intima the inner layer lined by a smooth tissue called endothelium.

Each artery is a muscular tube lined by smooth tissue and has three layers. They then give rise to the basilar arteries which supply the brain. What are the different coronary arteries.

The anatomy of arteries can be separated into gross anatomy at the macroscopic level and microanatomy which must be studied with a microscope. Below are some of the major arteries that are found in the body and. There are two main types of arteries.

The vertebral arteries enter the cranial cavity via the foramen magnum and converge. The coronary arteries originate as the right and left main coronary arteries which exit the ascending aorta just above the aortic valve coronary ostia. In elastic arteries the tunica media is rich with elastic and connective tissue.

The largest and most important artery in the circulatory system is the aorta. The exception the pulmonary artery carries oxygen depleted blood to the lungs for oxygenation and removal of excess carbon dioxide see. The right coronary artery supplies blood to the right ventricle the.

This system circulates nutrients to and removes waste material from the cells of the body. The left main coronary artery has a short common trajectory branching into the left anterior descending artery and the circumflex artery. Pulmonary arteries and systemic arteries.

Left and right common carotid. The arterial system of the human body is divided into systemic arteries carrying blood from the heart to the whole body and pulmonary arteries carrying deoxygenated blood from the heart to the lungs. These two branches subdivide and course over the surface of the heart epicardium as they traverse away from the aorta.

Arteries of the body major arteries of the body. There are two coronary arteries the right coronary artery and the left coronary artery which emerge from the ascending aort from the right and left aortic sinuses respectively. Artery in human physiology any of the vessels that with one exception carry oxygenated blood and nourishment from the heart to the tissues of the body.

Head and neck arteries. Right coronary artery rca. The adventitia connective tissue anchoring arteries to.

This is the opposite function of veins which transport blood to the heart. The vertebral arteries supply no branches to the neck or extra cranial structures. Arterial wall layers including the tunica intima and the tunica media.
