During which event of the cardiac cycle is systolic blood pressure measured? The atria and ventricles contract simultaneously. The atria and ventricles are relaxed, and blood flows into the atria. Blood flows into the relaxed atria while the ventricles contract. The atria contract while blood flows into the relaxed ventricles.

Which of the following are stages of the cardiac cycle? Select all that apply. An atrial contraction squeezes more blood into the relaxed ventricles. As relaxed atria fill, fluid pressure opens the atrioventricular valves, and blood flows into the relaxed ventricles. The ventricles start to contract and rising pressure shuts the atrioventricular valves and opens the aortic and pulmonary valves. As blood flows into the arteries, the pressure in the ventricles drops, and the aortic and pulmonary valves close. Which of the following components of blood is filled with hemoglobin and transports oxygen? White blood cell Red blood cell Platelet Plasma When blood pressure is measured, two blood pressures are recorded. select answer occurs as the contracting ventricles force blood into the arteries and is the highest pressure of the cardiac cycle. select answer , the lowest blood pressure of the cardiac cycle, occurs when the ventricles are fully relaxed.

Which step is part of the systole period of the cardiac cycle? • Blood fills the atria and pushes atrioventricular valves open. The heart is fully relaxed. and the atria begin to fill with blood. The ventricles contract fully, forcing the semilunar valves open and ejecting blood into the arteries. The atria contract, filling ventricles completely.

The cardiac cycle of the mammalian heart includes phases of systole and diastole of the chambers. During atrial and ventricular diastole, all four chambers are relaxed (the beginning of the cardiac cycle). What occurs next? atrial and ventricular systole: all chambers contract, forcing blood out of the heart to all circuits systole of the right ventricle and right atrium: blood is forced into the pulmonary artery only systole of the left ventricle and left atrium: blood is forced into the systemic circuit only atrial systole and ventricular diastole: the 2 atria contract and blood flows into the 2 ventricles
