Blood Flow in Humans: The heart is the organ responsible for moving blood through the body and setting our blood pressure. Blood is pumped out of the heart into the large arteries that then branch off into smaller and smaller vessels, then the blood returns to the heart through t...
Diastolic pressure is the lowest pressure recorded in the arteries during a cardiac cycle. From:Elsevier's Integrated Physiology,2007 About this page Add to MendeleySet alert Also in subject areas: Agricultural and Biological Sciences Biochemistry, Genetics and Molecular Biology ...
Your blood pressure is the measure of the force your heart uses to pump blood throughout the blood vessels in your body. It is shown by two numbers, where the first number indicates the systolic pressure. This is the pressure in your arteries during a heartbeat. The second number is calle...
This number measures how much pressure the blood is exerting against the artery walls when the heart beats. Diastolic, or the bottom number. This number measures pressure in the arteries when the heart is at rest between beats, at its lowest in the phase of circulation. Low blood pressure, ...
diastolic pressure- the blood pressure (as measured by a sphygmomanometer) after the contraction of the heart while the chambers of the heart refill with blood arterial pressure- the pressure of the circulating blood on the arteries; "arterial pressure is the product of cardiac output and vascular...
The systolic pressure is defined as the peak pressure in the arteries, which occurs near the beginning of the cardiac cycle; the diastolic pressure is the lowest pressure (at the resting phase of the cardiac cycle). The average pressure throughout the cardiac cycle is reported as mean arterial...
Blood pressure is a measurement of the force of blood being pushed against the walls of arteries. Blood pressure is measured in millimeters of mercury (mm Hg). This is an important diagnostic tool that can help medical professionals...
whereas during diastole the blood is moved into the heart due to a pressure difference between the vena cava and the right atrium, and pressure is lowest [12]. These periodic variations in pressure is what causes blood flow to be considered “pulsatile” [13]. This pulsatile action is what...
- Because the pressure is low, veins possess valves to prevent back flow and stop the blood from pooling at the lowest extremities Flow of blood in veins Blood is at very low pressure in the veins which can make it difficult for the blood to move against the downward force of gravity, ...
15.The patient's blood pressure is stable. 病人的血压平稳. 16.His blood pressure has stabilized. 他的血压已经稳定下来了. 17.Blood pressure and heart rate are typically at their lowest levels during sleep. 血压和心率通常在睡眠期间最低。
