The basic flow of blood
WebBlood flow must obey the principles of conservation of mass, momentum, and energy. Applied to any given region of space, the principle of conservation of mass means that whatever flows in must flow out. If flow is confined to blood vessels, then we obtain a rule similar to Kirchhoff’s law of electric circuits: At any junction the summation of ...

WebPulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs. It absorbs oxygen from tiny air sacs (the alveoli) and releases carbon … WebBranching Blood Vessels. The heart is a pump whose walls are made of thick muscle. They can squeeze (contract) to send blood rushing out. The blood does not spill all over the place when it leaves the heart. Instead, it flows smoothly in tubes called blood vessels. First, the blood flows into tubes called arteries.
WebThe semilunar valves stop the back flow of blood into the heart. There is a semilunar valve where the aorta leaves the left ventricle and another where the pulmonary artery leaves the right ventricle. WebThe pH of blood averages about 7.4; however, it can range from 7.35 to 7.45 in a healthy person. Blood is therefore somewhat more basic (alkaline) on a chemical scale than pure water, which has a pH of 7.0. Blood contains numerous buffers that actually help to regulate pH. Blood constitutes approximately 8 percent of adult body weight.
WebApr 25, 2024 · CHAPTER 1Introduction to basic hemodynamic principles James E. Faber and George A. Stouffer Hemodynamics is concerned with the mechanical and physiologic properties controlling blood pressure and flow through the body. A full discussion of hemodynamic principles is beyond the scope of this book. In this chapter, we present an … WebA vascular disease is a condition that affects the arteries and veins. Most often, vascular disease affects blood flow, either by blocking or weakening blood vessels, or by damaging the valves that are found in veins. Organs and other body structures may be damaged by vascular disease as a result of decreased or completely blocked blood flow.
WebPulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs. It absorbs oxygen from tiny air sacs (the alveoli) and releases carbon dioxide to be exhaled. Systemic circulation facilitates internal respiration: Oxygenated blood flows into capillaries through the rest of the body. The blood ...
