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 heart muscle has three layers and they are as follows:.

Blood must always circulate to sustain life. It carries oxygen from the air we breathe to cells throughout the body. The pumping of the heart drives this blood flow through the arteries, capillaries, and veins.
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 ]. For example, the left ventricular free wall and septum are usually discussed separately, yet both are formed by the same muscle Figure 1 and their function cannot be separated unless isolated focal lesions exist. For this reason, the anterior descending and posterior descending coronary arteries are simply vascular highways perched upon the top or bottom of the helical muscle forming the septum and its adjacent LV free wall.

Key chapters address animal models for cardiac research, cardiac mapping systems, heart-valve disease, and genomics-based tools and technology. Once again, a companion compact disk offers unique insights into the working heart, providing color images and movies that enhance the understanding of key points within the text.

Pulmonary Circulation and Systemic Circulation: The Routes and Function of Blood Flow
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.

Your heart does a lot of work to keep the body going. Each day, the average human heart beats about , times, pumping 2, gallons of blood through the body. In fact, the heart does more physical work than any other muscle over a lifetime. Located between the lungs in the middle of the chest, the heart pumps blood through the network of arteries and veins known as the cardiovascular system. Blood delivers oxygen and nutrients to every cell and removes the carbon dioxide and other waste products made by those cells.

Gianluca Pontone, Anatomy and physiology in ischaemic heart disease: a second honeymoon? Gaur et al. The marriage between coronary anatomy and physiology was sealed four decades ago with the evidence that progressive decreases in coronary lumen diameter resulted in reduced myocardial blood flow. Since that time, coronary artery revascularization has been based on visual assessment of the severity of coronary lumen diameter reduction during invasive coronary angiography ICA , assuming that this accurately reflects the physiological significance of the lesion.

Лжец! - выкрикнула Сьюзан. - Я видела твою электронную почту. Хейл замер, потом повернул Сьюзан лицом к. - Ты вскрыла мою электронную почту. - А ты отключил моего Следопыта.
На ВР отчетливо было видно, как уничтожалось окно программной авторизации. Черные всепроникающие линии окружили последний предохранительный щит и начали прорываться к сердцевине банка данных.
Беккер нахмурился. - Я вовсе не хочу с ней переспать. Мне нужно с ней поговорить. Ты можешь помочь мне ее найти.
Начала просматривать длинные строки символов на экране, пытаясь найти то, что вызвало задержку. Хейл посматривал на нее с самодовольным видом. - Слушай, я хотел спросить, - заговорил. - Что ты думаешь об этом не поддающемся взлому алгоритме, который, по словам Танкадо, он хотел создать.
Коммандер. Нет. Сьюзан словно окаменела, ничего не понимая.
Беккер повернул рычажок под топливным баком и снова нажал на стартер.
