The circulatory system of the lungs is the portion of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to the heart via the pulmonary vein. This viscosity is vital to the function of blood because if blood flows too easily or with too much resistance, it can strain the heart and lead to severe cardiovascular problems blood in the arteries is a brighter red than blood in the veins because of the higher levels of oxygen found in the arteries. Heart chambers and associated great vessels the contribute little to propulsion and pumping activity of the heart blood enters the right atrium heart anatomy. Intraoperatively, the anatomy of the heart is viewed from the right side of the supine patient via a median sternotomy incision the structures initially seen from this perspective include the superior vena cava, right atrium, right ventricle, pulmonary artery, and aorta.
The arteries, still defined as the vessels leading away from the heart, carry oxygen-poor blood to the lungs, and the veins carry oxygen-rich blood fr anatomy of a blood vessel wall the tunica intima, tunica media, and tunica externa. Study exercise 30: anatomy of the heart flashcards taken from the book human anatomy & physiology laboratory manual. Blood pumped by the heart flows through a series of vessels known as arteries, arterioles, capillaries, venules, and veins before returning to the heart arteries transport blood away from the heart and branch into smaller vessels, forming arterioles.
3 anatomy of the heart • the heart is a muscular organ a little larger than your fist weighing between 7 and 15 ounces (200 to 425 grams) • it pumps blood through the blood vessels. The heart has four separate chambers the upper two chambers are called the right and left atria (ra and la) the atria are the receiving chambers for blood returning from the body and the lungs. 2 lecture outline • cardiovascular system function • functional anatomy of the heart • myocardial physiology • cardiac cycle • cardiac output controls & blood pressure.

Blood supply to the heart the heart is a four-chambered muscular pump that is located within the mediastinum in the thoracic cavity it lies between the lungs and just superior to the diaphragm. Cardiovascular system anatomy tv problems contact murray jensen red blood cell blood vessels close to the heart: aorta, brachiochephalic, etc. Anatomy of the heart review sheet 30 251 gross anatomy of the human heart 1 7 provide nutrient blood to the heart muscle 8 lining of the heart chambers. The human cardiovascular system is made up of the heart, the blood it pumps, and the blood vessels, veins and arteries, through which the blood travels. Select the name of the part of the heart or blood vessel from the list below to see a picture and a description of what it does anatomy inside to understand how.
Vasculature of the heart tweet contents 1 naming chd can result in reduced blood flow to the heart as a result of narrowing or blockage of the coronary arteries. Embedded in the heart are valves that control blood flow and ensure that blood flows in a specified direction3,8 the heart in brief, the heart is a muscular organ enclosed in a double walled sack called the pericardium. The main job of the heart is to pump blood through a network of blood vessels these vessels form a loop that starts at the heart, goes out through your body, and then ends back at the heart again together, the heart, blood, and blood vessels are part of the circulatory system, which does two of the most important jobs in the body.
The heart is a muscular, four chambered organ that is responsible for distributing blood throughout the body the continuous activity of the heart creates a large demand for nutrients to be delivered to cardiac tissue and for waste to be removed.

How the heart works the heart is a large, muscular organ that pumps blood filled with oxygen and nutrients through the blood vessels to the body tissues.
