The cardiovascular system is sometimes called the blood - vascular , or simply the circulatory, 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.

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.

Circulatory 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….

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.

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.

Они уедут, потом остановятся где-нибудь в лесу. У него будет пистолет… От этой мысли у Стратмора свело желудок. Кто знает, что произойдет, прежде чем он решит освободить Сьюзан… если он ее вообще освободит. Я обязан позвонить в службу безопасности, - решил.  - Что еще мне остается? - Он представил Хейла на скамье подсудимых, вываливающего все, что ему известно о Цифровой крепости.  - Весь мой план рухнет. Должен быть какой-то другой выход.

Это за четыреста-то баксов. Я сказал ей, что даю пятьдесят, но она хотела. Ей надо было выкупить билет на самолет - если найдется свободное место перед вылетом.

Она ткнула его в ногу носком туфли. - Я сказала нет! - И, выдержав паузу, добавила: - И до вчерашней ночи это была правда. В глазах Сьюзан Дэвид был самим совершенством - насколько вообще такое .

 Совершенно верно.

 Я хочу вернуться домой, - сказала блондинка.  - Не поможете. - Опоздала на самолет.
