- 1Blood transports oxygen from the lungs to tissues for ________ _________Cellular metabolism
- 2Blood transports ________ _____ from the tissues to the lungs, where CO2 is removed from the bodyCarbon Dioxide
- 3O2 is carried by what in the blood?Hemoglobin
- 4How many grams of hemoglobin for every 100mL of blood?15 grams
- 5What does the oxygen hemoglobin dissociation curve illistrate?The curve illustrates the saturation of hemoglobin at various partial pressures.
- 6An decrease in core body temperature shifts the curve to the ______.Left
- 7An increase in core body temperature shifts the curve to the ______.Right
- 8What is a factor other that body temp. that influences the Oxygen Hemoglobin CurveArterial blood acidity.
- 9What allows the heart to beat on its own?Pacemaker
- 10What is the main intrinsic pacemaker>SA node
- 11The electrical conduction system starts with what?SA node
- 12The electrical impulse begins at the SA node spreads across the _____ to the __________ ______1. atrium
2. Atrioventricular node - 13After the electrical impulse spreads to the atrioventricular node, it moves to the __________ _______Purkinje fibres
- 14The pukinje fibers surround the ventricles. The impulses cause contractions of the heart in an order that causes the circulatory system to work. TRUE or FALSE?True
- 15Electrocardiogram records the hearts _____ ______ at the body's surface using ________ electrodes.1. electrical activity
2. 10-12 - 16In clinical settings, ECG's are NOT taken in incremental exercise tests to see what the heart does under stress. TRUE or FALSEFALSE
ECG's are taken in incremental exercise tests to see what the heart does under stress. - 17What is total peripheral resistance?Total peripheral resistance is the resistance of the entire systemic circulation. When blood vessels constrict, the peripheral resistance increases, whereas the dilation of vessels causes a decrease.
- 18Diastole is the _________ period. Systole is the _________ period.1. Relaxation
2. Contraction - 19What is systolic BP?Systolic pressure is the pressure put on arterial walls as the blood is forced from ventricular contractions.
- 20What is Rate Pressure Product (RPP)?The estimate of work on the heart.
- 21What is diastolic pressure?The pressure exerted on the arterial walls when there is a time of relaxation and no forceful ejection of blood.
- 22What is Mean Arterial Pressure (MAP)>MAP is the pressure in the cardiac cycle.
- 23Cardiac output is defined as the total amount of blood the heart pumps within a minute. TRUE or FLASETRUE
- 24Define Stroke Volume.The amount of blood ejected with each heart beat.
- 25Define end diastolic volume.The blood volume in the ventricles after filling them.
