The circulatory system , also called the cardiovascular system or the vascular system , is an organ system that permits blood to circulate and transport nutrients such as amino acids and electrolytes , oxygen , carbon dioxide , hormones , and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases , stabilize temperature and pH , and maintain homeostasis. The circulatory system includes the lymphatic system , which circulates lymph. Lymph is essentially recycled excess blood plasma after it has been filtered from the interstitial fluid between cells and returned to the lymphatic system.

When a person is anaemic, the red blood cells have to work harder to get oxygen around the body. An aneurysm may have no symptoms until it is either very large or it ruptures. Aortic stenosis may be congenital present from before birth , but is often diagnosed during teenage years.

The cardiovascular system can be thought of as the transport system of the body. This system has three main components: the heart , the blood vessel and the blood itself. Blood can be thought of as a fluid which contains the oxygen and nutrients the body needs and carries the wastes which need to be removed. The following information describes the structure and function of the heart and the cardiovascular system as a whole. The heart is located in between the two lungs. It lies left of the middle of the chest. Structure of the Heart The heart is a muscle about the size of a fist, and is roughly cone-shaped.

The circulatory system consists of three independent systems that work together: the heart cardiovascular , lungs pulmonary , and arteries, veins, coronary and portal vessels systemic. The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells. An average adult has 5 to 6 quarts 4. The heart is a muscular organ with four chambers. Located just behind and slightly left of the breastbone, it pumps blood through the network of arteries and veins called the cardiovas- cular system. The systemic circulation is a major portion of the circulatory system. The network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body's cells and then returns deoxygenated blood back to the heart.

The organs of the circulation angiologia include the bloodvascular system and the lymphatic system. The bloodvascular system systema cardiovasculare consists of the heart, its central organ, and the blood vessels among which we differentiate the arteries, running centrifugally from the heart, and the veins which are directed towards the heart. The arterial and venous networks are connected by the capillaries.

Circulatory system , system that transports nutrients, respiratory gases, and metabolic products throughout a living organism, permitting integration among the various tissues. The process of circulation includes the intake of metabolic materials, the conveyance of these materials throughout the organism, and the return of harmful by-products to the environment. Invertebrate animals have a great variety of liquids, cells, and modes of circulation, though many invertebrates have what is called an open system, in which fluid passes more or less freely throughout the tissues or defined areas of tissue. All vertebrates, however, have a closed system—that is, their circulatory system transmits fluid through an intricate network of vessels.

 Испанская церковь гордится тем, что ей принадлежат его останки. Испанская церковь. Беккер отлично знал, что в Испании только одна церковь - римско-католическая. Католицизм здесь посильнее, чем в самом Ватикане. - У нас, конечно, не все его тело, - добавил лейтенант.

Все закончилось. Действительно закончилось. Теперь можно возвращаться домой. Кольцо на пальце и есть тот Грааль, который он искал. Беккер поднял руку к свету и вгляделся в выгравированные на золоте знаки. Его взгляд не фокусировался, и он не мог прочитать надпись, но, похоже, она сделана по-английски. Первая буква вроде бы О, или Q, или ноль: глаза у него так болели.

Под визг покрышек, в снопе искр Беккер резко свернул вправо и съехал с дороги. Колеса мотоцикла подпрыгнули, ударившись о бетонное ограждение, так что он едва сумел сохранить равновесие. Из-под колес взметнулся гравий. Мотоцикл начал подниматься по склону. Колеса неистово вращались на рыхлой земле.
