What phase of the cardiac cycle is longest?
Atria Diastole is the longest (0.7sec)
What is occurring during the diastolic period?
Diastole is the phase in the cardiac cycle that allows filling of blood into the ventricle. It corresponds to the lower number in the blood pressure measurement. A normal upper limit of the blood pressure falls in the range less than 120/80 mm Hg. Above this value, it is considered pre-hypertension based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.During the diastolic period the ventricle is in the fifth phase of the cardiac cycle. This phase is termed isovolumetric relaxation which occurs immediately after the second heart sound. In this phase, all valves of the heart are closed. The volume of blood in the ventricle during this phase of the cardiac cycle remains constant. Following the fifth phase of the cardiac cycle is the rapid filling of blood into the ventricle. This cycle corresponds to the opening of the mitral and tricuspid valves located between the left and right atria and ventricle, respectively. The next phase of the cardiac cycle, called diastasis, is the longest phase of the cardiac cycle. In this cycle, the ventricle continues to fill with blood but at a much slower rate. The final phase of diastole corresponds to the first phase of the cardiac cycle. In this phase of the cardiac cycle, the atria contracts to provide additional filling of blood into the ventricle. After the final phase of diastole, the systolic phase of the cardiac cycle begins.
The longest phase of the cell cycle is what?
The longest phase of the cell cycle is typically the interphase, which includes the G1, S, and G2 phases. The actual length of each phase can vary depending on the cell type and its specific requirements for growth and division.
What is the relaxing phase of the cardiac cycle?
The relaxing phase of the cardiac cycle is called diastole. During diastole, the heart chambers (atria and ventricles) relax, allowing them to fill with blood. This is followed by the contracting phase called systole.
Which part of the cell cycle is the longest part?
The longest part of the cell cycle is typically the interphase, particularly the G1 phase. This is when the cell grows and carries out its normal functions before entering the synthesis (S) phase to replicate its DNA.
What phase of the cardiac cycle is longest?
Atria Diastole is the longest (0.7sec)
Longest phase in cell cycle?
The G1 phase
What is the longest phase of the entire cell cycle?
Interphase is the longest phase in the cell cycle lasting 18 of the 20 hour cycle. In mitotic cell division cycle,the longest phase is G1 phase which lasts for 10 hours,S phase is for 9 hours,G2 phase for 4 hours and shortest phase is M phase which lasts for 1 hour.
Which is the phase of cardiac cycle in which the auricles contract?
The auricles will contract during the systolic phase of the cardiac cycle. This is one of the numbers that is measured when a patient has their blood pressure taken.
What is the name given to contraction phase of the cardiac cycle?
The contraction phase of the cardiac cycle is called systole. This is when the heart muscle contracts to pump blood out of the heart and into the circulatory system.

Longest phase of cell cycle?
Interphase
When do the AV valve close during the cardiac cycle?
AV valves close during the systole phase of the cardiac cycle.
What is the alternating relaxation and contraction of the heart called?
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
Phase of the cardiac cycle that shortens most in response to tachycardia?
diastolic
What is usually the longest phase of a population's life cycle?
The longest phase of a population's life cycle is typically the adult phase. This phase encompasses the majority of an organism's lifespan, during which it is capable of reproduction and contributes to the growth and stability of the population. This phase is followed by senescence, or the decline in physiological function, and ultimately death.
What is the busiest phase of cell cycle?
Interphase is the longest of the cell cycle. Interphase, the busiest phase of the cell cycle, is divided into three parts.
