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 cardiovascular system is sometimes called the blood - vascular , or simply 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. As the name implies, blood contained in the circulatory system is pumped by the heart around a closed circle or circuit of vessels as it passes again and again through the various "circulations" of the body. As in the adult, survival of the developing embryo depends on the circulation of blood to maintain homeostasis and a favorable cellular environment. In response to this need, the cardiovascular system makes its appearance early in development and reaches a functional state long before any other major organ system. Incredible as it seems, the primitive heart begins to beat regularly early in the fourth week following fertilization.

Organs of the Circulation

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. The cardiovascular from Latin words meaning "heart" and "vessel" system comprises the blood, heart, and blood vessels. The circulatory system of the blood is seen as having two components, a systemic circulation and a pulmonary circulation. While humans, as well as other vertebrates , have a closed cardiovascular system meaning that the blood never leaves the network of arteries , veins and capillaries , some invertebrate groups have an open cardiovascular system.

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. The blood circulating within these vessels, the organs of blood formation haematopoiesis and the organs responsible for the breakdown of the blood cells are also part of the bloodvascular system.

Oxygen enters the bloodstream through tiny membranes in the lungs that absorb oxygen as it is inhaled. As the body uses the oxygen and processes nutrients, it creates carbon dioxide, which your lungs expel as you exhale. A similar process occurs with the digestive system to transport nutrients, as well as hormones in the endocrine system. These hormones are taken from where they are produced to the organs they affect. The circulatory system works thanks to constant pressure from the heart and valves throughout the body. This pressure ensures that veins carry blood to the heart and arteries transport it away from the heart. The coronary sinus is a collection of smaller veins that merge together to form the sinus or large vessel , which is located along the heart's….


Heart: Provides the force to "push" the blood throughout the body. Arteries: Carry blood away from the heart to the rest of the body. Veins: Carry blood to the heart from the rest of the body. Capillaries: The smallest blood vessels.


Organs of the Circulation

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.

Introduction to the Cardiovascular System

Blood circulates through a network of vessels throughout the body to provide individual cells with oxygen and nutrients and helps dispose of metabolic wastes. The heart pumps the blood around the blood vessels. The plasma is largely water, containing proteins, nutrients, hormones, antibodies, and dissolved waste products. The heart is a hollow muscular organ which beats over , times a day to pump blood around the body's 60, miles of blood vessels. The right side of the heart receives blood and sends it to the lungs to be oxygenated, while the left side receives oxygenated blood from the lungs and sends it out to the tissues of the body. In a normal heart beat the atria contract while the ventricles relax, then the ventricles contract while the atria relax.

 Верно. Но я хочу иметь копию. Я хочу открыть этот проклятый файл и ознакомиться с созданной Танкадо программой. Сьюзан была столь же любопытна, как и ее шеф, но чутье подсказывало ей, что расшифровка алгоритма Цифровой крепости неразумна, какой бы интерес это ни представляло. В данный момент эта чертова программа надежно зашифрована и абсолютно безопасна. Но как только шифр будет взломан… - Коммандер, а не лучше ли будет… - Мне нужен ключ! - отрезал. Сьюзан должна была признать, что, услышав о Цифровой крепости, она как ученый испытала определенный интерес, желание установить, как Танкадо удалось создать такую программу.

Беккер в очередной раз послал бармену проклятие за коктейль, выбивший его из колеи. Это был один из старых потрепанных севильских автобусов, и первая передача включилась не. Расстояние между Беккером и ним сокращалось. Нужно было во что бы то ни стало догнать его, пока не включилась следующая передача. Сдвоенная труба глушителя выбросила очередное густое облако, перед тем как водитель включил вторую передачу.

На лицах тех застыло недоумение. - Давайте же, ребята. -сказал Джабба.  - Вы же учились в колледжах. Ну, кто-нибудь.

Пульс ее участился. На мониторе появилось символическое изображение конверта - это значило, что пришло сообщение по электронной почте. Сьюзан бросила быстрый взгляд на Хейла, но тот был всецело поглощен своим компьютером. Затаив дыхание, Сьюзан дважды щелкнула по конверту. - Северная Дакота, - прошептала она еле слышно.  - Посмотрим, кто ты. Сьюзан прочитала открывшееся сообщение, которое состояло из одной строчки, потом прочитала его еще .

 - Вы рискуете попасть в Сьюзан. Хейл выжидал.

 Я-я…я убью. Клянусь, убью. - Ты не сделаешь ничего подобного! - оборвал его Стратмор.  - Этим ты лишь усугубишь свое положе… - Он не договорил и произнес в трубку: - Безопасность. Говорит коммандер Тревор Стратмор.

 - Он замолчал, словно подбирая нужные слова.  - Этот шифр взломать невозможно. Сьюзан посмотрела на него и едва не рассмеялась. Невозможно.

 И Танкадо отдал это кольцо совершенно незнакомому человеку за мгновение до смерти? - с недоумением спросила Сьюзан.  - Почему. Стратмор сощурил. - А ты как думаешь.
