Yes, the vena cava does receive blood during left ventricular systole. During this phase, the left ventricle contracts, pumping oxygenated blood into the aorta. Meanwhile, the right atrium, which receives blood from the superior and inferior vena cava, is filling with deoxygenated blood returning from the body. Therefore, while the left ventricle is actively pumping, the vena cava continues to bring blood into the heart.
ventricular systole
ventricular systole
Right ventricular systole is pumping blood into the PULMONARY ARTERIES just as left ventricular systole is pumping blood into the AORTA -- both at the same time.Source: http://library.med.utah.edu/kw/pharm/hyper_heart1.htmlIn right ventricular systole, the blood enters the pulmonary trunk before proceding into the pulmonary arteries.
The pressure in the aorta is greatest during ventricular systole, which is when the heart contracts and pumps blood into the aorta. This creates a surge in pressure that is known as systolic blood pressure.
The ventricular systole lasts for about 0.3 seconds, during which time the ventricles of the heart contract to push blood out into the arteries.
It is called systole. This is when the ventricles contract and eject blood into the lungs (from the right ventricle) or into the systemic circulation (from left ventricle).
A. systole causes a complete emptying of all blood from the ventricle B. systole increases the pressure in the ventricles ejecting blood out through the cardiac outflow tracts C. systole occupies a longer period of time than does diastole. D. systole is the phase of the cardiac cycle when the heart fills with blood. E. None of the above
The Aorta
The term used for arterial pressure during ventricular systole is systolic blood pressure. It represents the maximum pressure exerted on the walls of the arteries when the heart contracts and pumps blood into the circulatory system.
Because not all of the blood that is in the heart, which was brought in during diastole, is ejected during systole. There is some back flow of blood, which can't make it over the aortic arch because of lack of pressure, into the heart.
Systole is the phase during which the heart contracts resulting in the movement of blood to the peripheral parts of the body. The contractile force causes increase in the pressure of the arteries, greater than the diastole which makes it possible for the blood to reach the body.
In late diastole (relaxation phase), the semilunar (pocket) valves close, due to decreasing arterial pressure, to prevent blood flowing back into the ventricles. These stay closed during atrial systole. (But open again during ventricular systole.)Then, as the ventricles contract during ventricular systole, the bicuspid and tricuspid valves close to prevent blood from flowing back to the atria.So, it really depends on which phase of the contraction we are looking at.(Ed: format)
