Like the bustling factory, the body must have a transportation system to carry its various cargos back and forth, and this is where the cardiovascular system steps in. The cardiovascular system can be compared to a muscular pump equipped with one-way valves and a system of large and small plumbing tubes within which the blood travels.

The cardiovascular system consists of the heart, blood vessels, and the blood, which transports materials to and from all parts of the body.

What Is the Heart? Anatomy, Function, Pathophysiology, and Misconceptions

Biomechanics aims to explain the mechanics of life and living. From molecules to organisms, everything must obey the laws of mechanics — Y. The primary function of the cardiovascular system is mass transport, that is, the transport of oxygen, carbon dioxide, nutrients, waste products, hormones, etc. This system consists primarily of the heart , which serves as the pump, the blood , which serves as the conducting medium, and the vasculature , which serves as the conduit through which the blood flows. Closely related systems are the cardio-pulmonary and reno-vascular systems. The primary organs of the pulmonary system are the lungs, which facilitate the exchange of oxygen and carbon dioxide between the blood and external environment, whereas the primary organs of the renal system are the kidneys, which serve as filters to remove waste products from the blood. Although studying the pulmonary and renal systems is important, interesting, and challenging, we shall focus on the heart and vasculature in this chapter.

The heart itself is made up of 4 chambers, 2 atria and 2 ventricles. De-oxygenated blood returns to the right side of the heart via the venous circulation. It is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed. The oxygenated blood then travels back to the left side of the heart into the left atria, then into the left ventricle from where it is pumped into the aorta and arterial circulation. The pressure created in the arteries by the contraction of the left ventricle is the systolic blood pressure.

Cardiovascular System Anatomy and Physiology

The cardiovascular system is a closed system if the heart and blood vessels. The heart pumps blood through a closed system of blood vessels. Blood vessels allow blood to circulate to all parts of the body. The vital importance of the heart is obvious. If one assumes an average rate of contraction of 75 contractions per minute, a human heart would contract approximately , times in one day, more than 39 million times in one year, and nearly 3 billion times during a year lifespan.

Key chapters address animal models for cardiac research, cardiac mapping systems, heart-valve disease, and genomics-based tools and technology.

The Cardiovascular System — Anatomy, Physiology and Cell Biology

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 lymphatic system, on the other hand, is an open system providing an accessory route for excess interstitial fluid to be returned to the blood.

The current approach to understanding cardiac dynamics relies upon movements that adhere to the conventional topographical separation of cardiac muscle into the left ventricle, right ventricle, and septum. Functional analyses have addressed them independently, and this approach has resulted in many suppositions that this report will define and question. Alternatively, cardiac muscle mass is formed by the helix and surrounding circumferential wrap described by Lower in the s [ 1 ], Senac in the s [ 2 ], Krehl in the s [ 3 ], Mall in the s [ 4 ], and more recently by Torrent Guasp [ 5 ].

 Откуда вам это известно. - Это не имеет отношения к делу. Нуматака выдержал паузу. - А если мистер Беккер найдет ключ. - Мой человек отнимет .

 - Мы можем принять участие в аукционе. Стратмор покачал головой: - Танкадо дал нам шанс. Это совершенно ясно.

Беккер как завороженный смотрел на человека, входящего в туалетную комнату. Он показался ему смутно знакомым. - Soy Hulohot, - произнес убийца.

Но когда он начал подниматься на следующую ступеньку, не выпуская Сьюзан из рук, произошло нечто неожиданное. За спиной у него послышался какой-то звук. Он замер, чувствуя мощный прилив адреналина. Неужели Стратмор каким-то образом проскользнул наверх. Разум говорил ему, что Стратмор должен быть не наверху, а внизу.

Загруженная громадным количеством информации программа создавала паутину относительных величин - гипотетическую модель взаимодействия политических переменных, включая известных политиков, их штабы, личные взаимоотношения, острые проблемы, мотивации, отягощенные такими факторами, как секс, этническая принадлежность, деньги и власть. Пользователь имел возможность создать любую гипотетическую ситуацию, и Мозговой штурм предсказывал, как эта ситуация повлияет на среду. Коммандер относился к этой программе с религиозным трепетом, но использовал ее не в политических целях: она служила ему для расчета времени, оценки информации и схематического отображения ситуации, выработки сложных стратегических решений и своевременного выявления слабых мест. Сьюзан не оставляло подозрение, что в компьютере шефа кроется нечто, чему в один прекрасный день суждено изменить весь мир.

Она побледнела. - Что с тобой? - удивленно спросил Хейл. Сьюзан встретилась с ним взглядом и прикусила губу.
