  2. Hemodynamics - Wikipedia

    en.wikipedia.org/wiki/Hemodynamics

    Hemodynamics explains the physical laws that govern the flow of blood in the blood vessels. Blood flow ensures the transportation of nutrients , hormones , metabolic waste products, oxygen , and carbon dioxide throughout the body to maintain cell-level metabolism , the regulation of the pH , osmotic pressure and temperature of the whole body ...

  3. Hemodynamics of the aorta - Wikipedia

    en.wikipedia.org/wiki/Hemodynamics_of_the_Aorta

    The hemodynamics of the aorta is an ongoing field of research in which the goal is to identify what flow patterns and subsequent forces occur within the thoracic aorta. These patterns and forces are used to identify the presence and severity of cardiovascular diseases such as aortic aneurysm and atherosclerosis . [ 1 ]

  4. Wiggers diagram - Wikipedia

    Blood pressure. Aortic pressure; Ventricular pressure; Atrial pressure; Ventricular volume; Electrocardiogram; Arterial flow (optional) Heart sounds (optional) The Wiggers diagram clearly illustrates the coordinated variation of these values as the heart beats, assisting one in understanding the entire cardiac cycle.

  5. Lumped parameter model for the cardiovascular system

    en.wikipedia.org/wiki/Lumped_parameter_model_for...

    A lumped parameter cardiovascular model is a zero-dimensional mathematical model used to describe the hemodynamics of the cardiovascular system. Given a set of parameters that have a physical meaning (e.g. resistances to blood flow), it allows to study the changes in blood pressures or flow rates throughout the cardiovascular system.

  6. Pressure–volume loop analysis in cardiology - Wikipedia

    en.wikipedia.org/wiki/Pressure–volume_loop...

    Several physiologically relevant hemodynamic parameters such as stroke volume, cardiac output, ejection fraction, myocardial contractility, etc. can be determined from these loops. To generate a PV loop for the left ventricle, the LV pressure is plotted against LV volume at multiple time points during a single cardiac cycle .

  7. Hemorheology - Wikipedia

    en.wikipedia.org/wiki/Hemorheology

    Blood viscosity is a measure of the resistance of blood to flow. It can also be described as the thickness and stickiness of blood. This biophysical property makes it a critical determinant of friction against the vessel walls, the rate of venous return, the work required for the heart to pump blood, and how much oxygen is transported to tissues and organs.

  8. Venous return - Wikipedia

    en.wikipedia.org/wiki/Venous_return

    Venous return (VR) is the flow of blood back to the heart. Under steady-state conditions, venous return must equal cardiac output (Q), when averaged over time because the cardiovascular system is essentially a closed loop. Otherwise, blood would accumulate in either the systemic or pulmonary circulations.

  9. Cardiovascular physiology - Wikipedia

    en.wikipedia.org/wiki/Cardiovascular_physiology

    Blood flow through the left coronary artery is at a maximum during diastole (in contrast to the rest of systemic circulation, which has a maximum blood flow during systole.) splanchnic circulation: 15%: low: Flow increases during digestion. hepatic circulation: 15%: Part of portal venous system, so oncotic pressure is very low renal circulation ...
