Illuminate the Truth Stroke VolumeHighlight the correct word in each of the following sentences.1. (Preload)(Afterload) is the amount of tension, or stretch, in the ventricular muscle just before it contracts.2. (Contractility)(Stroke volume) is the force with which ventricular ejection occurs.3. Starling's law of the heart states that the more the ventricle is stretched-within limits-the (less)(more)forcefully it will contract.4. The force against which the heart must work to eject its volume of blood is called the (cardiacoutput)(afterload).5. Factors that affect contractility are called (chronotropic) (inotropic) agents.6. Factors that affect heart rate are called (diastolic)(chronotropic) agents.

Indicate the correct order of the sequence of events occurring during congestive heart failure. Order the sentences (Hint: End with "g") This question is a great summary of what happens, in steps, in congestive heart failure. a. narrowed bicuspid valve makes the L atrium pump harder in order to "push" blood into the L ventricle through an opening that is too narrow. b. pressure of the extra, backed up blood in the lung creates pressure in the capillaries that begin to leak fluid into the lung. c. extra "left-over" blood in the atrium that has not descended into the ventricle after a beat has nowhere to go. d. congenital heart defect causes a narrowed bicuspid valve e. not all blood gets "pushed" from the L atrium to the L ventricle during a regular heart beat f. blood that backed up in the L atrium with nowhere to go backs up further, into the pulmonary veins and eventually into the lung g. the patient gets less oxygen with each breath, feels tired all the time and is…

I need help with a respiratory question, thank you, I really appreciate it Stroke volume can be calculated using which formula? Group of answer choices End-diastolic volume – end-systolic volume Ejection fraction × heart rate Ejection fraction × end-systolic volume Cardiac output ÷ end-diastolic volume
ANSWER THIS QUESTION BY RELATING IT TO THE PHOTOSKIP THIS IF YOU ALREADY ANSWERED OTHERWISE DOWNVOTE.Explain how the following factors affect the blood velocity and volume flow rate as well as potential risks for stroke: i. the pulsatile nature of blood flow, ii. elasticity of the wall of the blood vessels, and iii. gradual narrowing and curvature of blood vessels.
which arrhythma refers to rapid, random, inefficient, and irregular contrations of the atria and ventricles(350 beats or more per minute) 1. Flutter 2. Bradycardia 3. Fibrillation
Indicate which of the following sentences is true in heart failure caused by stenosis of the mitral valve. Group of answer choices 1)Anytime a valve is stenotic, the L atrium must generate a greater force than normal to attempt to move blood through the narrowed opening. This decreases the workload on the heart, eventually leading to an inoperative muscle. 2)Anytime a valve is stenotic, the L atrium must generate a greater force than normal to attempt to move blood through the narrowed opening into the L ventricle. This increases the workload on the heart, eventually leading to its weakening and failing. 3)Anytime a valve is stenotic, the R atrium cannot generate greater force than normal to attempt to move blood through the narrowed opening, and it fails. 4)Anytime there is valve regurgitation, the heart must generate a greater force than normal to attempt to move blood through the narrowed opening into the ventricle. This increases the workload on the heart,…
