Autoregulation of blood flow may be defined as the adjustment of blood flow through an organ to provide for its metabolic needs. Autoregulation is a part of homeostasis, which is the more general term for the stability in the internal environment achieved by control mechanisms activated by ...
Blood flow refers to the movement of blood through a vessel, tissue, or organ, and is usually expressed in terms of volume of blood per unit of time. It is initiated by the contraction of the ventricles of the heart. Ventricular contraction ejects blood into the major arteries, resulting in...
Blood flows (mL/min/g tissue) to organs were determined using reference organ techniques. Control animals displayed no alterations in any of the variables monitored. Throughout the experimental period, organ blood flows were almost uniformly lower (pKey Words: hypoxemia, mesenteric blood flow, ...
What circulation describes the flow of blood from the heart to the myocardium? Blood enters the heart from the systemic circulation through what blood vessels? What is it called when blood is pumped away from your heart and into your body?
Computational simulations of coronary artery blood flow, using anatomical models based on clinical imaging, are an emerging non-invasive tool for personalized treatment planning. However, current simulations contend with two related challenges – incomplete anatomies in image-based models due to the exclu...

1.12.5 The Blood Flow Model The Renkin–Crone model shows that for highly permeable tracers, K1 is limited by the rate of blood flow through the capillary bed of the tissue. Thus, tracers such as [13N]ammonia and [15O]water can be used to obtain quantitative estimates of blood flow. ...
We shall now apply the general principles discussed in the preceding chapters to one organ, the lung. The purpose is to illustrate, in one concrete example, the use of physical principles, with the help of anatomy and histology, to explain and predict the function of an organ in quantitative...
An important application of the one-tissue model is the measurement of regionalblood flow.Blood flowcan be described as the volume of blood that passes through a blood vessel per unit time (e.g., ml/min). However, the regional measurement of blood flow is typically expressed as the blood ...
A method for protecting at least one gonad from a blood borne cytotoxic drug, the method comprising reducing blood flow to at least one gonad of a patient undergoing cytotoxic treat
