Heart Anatomy Coronary Arteries. Because the heart is composed primarily of cardiac muscle tissue that continuously contracts and relaxes, it must have a constant supply of oxygen and nutrients. The coronary arteries are the network of blood vessels that carry oxygen-and nutrient-rich blood to the cardiac muscle tissue.ecause the heart is composed primarily of cardiac muscle tissue that continuously contracts and relaxes, it must have a constant supply of oxygen and nutrients.

- in muscle: Structure and organization. The heart is a network of highly branched cardiac cells 110 μm in length and 15 μm in width, which are connected end to end by intercalated disks. The cells are organized into layers of myocardial tissue that are wrapped around the chambers of the heart.

Structure of the Heart The two ventricles are thick-walled chambers that forcefully pump blood out of the heart. Differences in thickness of the heart chamber walls are due to variations in the amount of myocardium present, which reflects the amount of force each chamber is required to generate. The right atrium receives deoxygenated blood from systemic veins; the left atrium receives oxygenated blood from the pulmonary veins.

The cardiovascular system consists of the following? Please supply the omission. The main components of the human cardiovascular system are the heart, blood, and blood vessels.[3] It includes: the pulmonary circulation, a loop through the lungs where blood is oxygenated; and the systemic circulation, a loop through the rest of the body to provide oxygenated blood.ating Newest Oldest. Best Answer: The cardiovascular system is sometimes called the circulatory system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.

Consists of a tough fibrous layer of dense irregular tissue that is fused to the inner surface of the fibrous pericardium, and a thin, smooth, moist serous layer. Visceral Pericardium. Also called the epicardium; formed at the base of the heart where the serous layer turns inward.

Layers of the Heart Layers of the Heart. The heart consists of three layers in all. This Buzzle article explains the structure and function of each of these layers. The heart is one of the most important organs present in the human body. This organ is responsible for pumping blood to all parts of the body. Thus, it is considered as the main organ of the circulatory system. The heart is made up of specialized, smooth muscle tissue known as cardiac muscles or myocardium.

heart The heart wall is composed of three layers of tissues. Its chambers are lined by a delicate membrane, the endocardium. The thick muscular wall essential to normal pumping action of the heart is called the myocardium. The thin but sturdy membranous sac surrounding the exterior of the heart is called the pericardium.

Heart Structure - Anatomy & Physiology Position and Shape of the Heart. The heart is located in the thoracic cavity in between the lungs, 60% of it lying to the left of the median plane. The heart’s lateral projection extends from rib 3 to 6. Most of the heart’s surface is covered by the lungs and in juveniles it is bordered cranially by the thymus.he pericardium is the membrane that surrounds and protects the heart. It is composed of two layers separated by a narrow cavity. The inner layer is firmly attached to the heart wall and is known as the visceral layer or epicardium.

- The heart is a muscular structure with four chambers including two atria, which are the filling chambers and two ventricles, which are the pumping chambers. The venous blood is drained from the body to the right chambers of the heart, then oxygenated in the lungs and ejected to the entire body by the left chambers of the heart.

Heart In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium. The heart pumps blood with a rhythm determined by a group of pacemaking cells in the sinoatrial node.
