Question

Respond to prompts 1-8 below by identifying heart valves and stages in the cardiac cycle: The valves between the atria and ventricles The relaxation phase of the cardiac cycle when the chambers fill with blood The contraction phase of the cardiac cycle that pumps blood The pressure in the arteries in this phase is the top number in a blood pressure reading The valves between the ventricles and the arteries These valves are open in diastole The pressure in the arteries in this phase is the bottom number in a blood pressure reading These valves are open in ventricular systole Which type of blood vessel (artery, vein, capable) is being described in 9-22? Surrounded by the thickest sheath of smooth muscle One-way valves prevent backflow of blood Thin vessel formed by a single layer of cells and some associated support cells Blood velocity is highest Blood velocity is lowest Blood pressure is highest Blood pressure is lowest Pulse is felt as the stretching of the walls of this vessel This vessel carries out the most important function of the circulatory system -transfer of nutrients, gases, and wastes Sphincters can control blood flow through this type of vessel At the arterial end of this vessel, blood pressure causes net movement out of this vessel At the venous end of this vessel, osmotic pressure causes net movement into this vessel This vessel always carries blood away from the heart This vessel always carries blood toward the heart Look at Figure 23.3A in your textbook and label 1-10.

Explanation / Answer

1- Bicuspid and tricuspid valves are present in between the atria nad ventricles

2- Diastole phase of the cardiac cycle is the relaxation phase of the cardiac cycle in which the chambers fills with blood.

3.The systolic phase of the Cardiac cycle is the phase in which it pumps blood.

4.the pressure in the arteries at the time of systolic phase of heart will be 120 mmHg

5. Aortic valve and pulmonic valves remain present between ventricles and arteries.

6. Bicuspid and tricuspid valves remain open during diastole.

7.Diastolic phase in which pressure drops to minimum

8.semilunar valves means aortic and pulmonic valves remain open during ventricular systole
