The heart consists of four chambers that are connected in such a way that contraction of them causes the heart to act as a pump, the right half of the heart passing blood from the venae cavae to the pulmonary circulation for oxygenation and the left half of the heart pumping oxygenated ...
The cardiac cycle is the sequence of events that occurs when theheartbeats. As the heart beats, it circulates blood throughpulmonary and systemic circuitsof the body. There are two phases of the cardiac cycle: The diastole phase and the systole phase. In the diastole phase, heartventriclesrel...
6. Cardiac cycle of healthy heart A single cardiac cycle consists of two primary phases- diastole and systole. The term “diastole” denotes relaxation, and the term “systole” refers to contraction [3]. 6.1 Diastole During the diastolic phase, blood flows into the right atrium from the ...
The Cardiac Cycle The cardiac cycle can be divided into four stages: Filling phase –the ventricles fill during diastole and atrial systole. Isovolumetric contraction –the ventricles contract, but as the heart valves are shut, the volume remains constant. This causes a build-up of pressure, re...
Figure 1. The cell cycle consists of interphase and the mitotic phase. During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The ...

The sphygmomanometer consists of a rubber bag inside a cloth cuff that is wrapped around the upper arm, just above the elbow. The rubber bag is inflated with air using a hand bulb pump. As the bag is pumped up, the pressure ...
of one side occurs simultaneously with the contraction of the other. So the first and second stages of diastole in the cardiac cycle happen simultaneously, and then the first and second stages of systole occur. The “lub-dup” noise heard when listening to the heartbeat is the sound of ...
Explain the cardiac cycle in the four-chambered heart. The flow of blood through the heart and around the body is called what? What is the function of the interatrial septum in the heart? The cardiovascular system consists of all the following except: A. The heart B. Blood vessels C. Vei...
The heart contains a cycle of contraction (systole) and relaxation (diastole) between each heartbeat. This cycle is called the cardiac cycle. The...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
