Cardiac cycle Flashcards
What is the term used to describe a resting heart rate?
Bradycardia
What is the correct timing for the systole phase of a heart beat?
0.3 seconds
What are the benefits of active cool down?
Allows body temperature, blood pressure and heart rate to return to normal/ Stretching can help reduce lactic acid build up, reduces chance of muscle cramp and stifnesss.
What are arteries?
Carry blood away from the heart (carry oxygenated blood(
What side is the right side of the heart?
Heart receives blood from pulmonary vein which is deoxygenated picks up then o2 from lungs after
What is the left side of the heart?
Oxygenated blood received from the vena cava, from the lungs
What are the stages of the cardiac?
Diastole- no impulse, arias receive blood from pulmonary/ vena cava
atrial systole- both tries contract (duel pump mechanism) to force blood into ventricles through bicupsid/tricuspid
ventriclur systeole- both ventricles contract and eject the blood into the pulmonary artery and aorta for transportation around the pulmonary system and systematic
What is the heart rate for an untrained athlete at rest?
60-75bpm
What is the stroke volume for an untrained athlete at rest>
70ml/beat
What is the cardiac output at rest?
51/min
What is the maximal heart rate for an untrained performer?
220-age
What is the maximal stroke volume for an untrained performer?
100-120ml per beat
What is the maximal cardiac output for an untrained performer?
20-30 ml ejected from the left ventricle per beat
What is heart rate?
The number of beats of the heart per minute
What is the stroke volume?
The volume of blood ejected from the left ventricle per beat
What is the cardiac output?
The volume of blood ejected from the left ventricle per minute
What is the heart rate for a trained performer at rest>
50 beats per minute
What is the resting stroke volume for a trained athlete?
100ml/beat
What is the cardiac output of a trained performer at rest>
51/min
What is the maximal heart rate for a trained performer?
220-age
What is the maximal stroke volume of a trained performer?
160-200ml
What is the maximal cardiac output of a trained performer?
30-40 l/min
When muscles are contracting what detects it and what happens to inmate movement?
Break down of fats are needed to happen, so symatheit nervous system is notified which is by th receptors; baro,chemo, proprio from the blood vessels blood and muscles that pressure, lactic and movement has occurred. The ccc sends impulses down accelerator nerve for the atria to contract
When the body has finished exercising what dos the body do to reduce the heart rate?
Parasymapthic system is noticed to reduce stimulation of sa node reducing the heart rate to rest in medulla oblongata. The decrease of this is sent down the tragus nerve
What are capillaries?
Allow for gas, nutrients and waste exchange
What are arterioles?
carry oxygenated blood from the heart- left ventricle
What are the venues?
Smaller blood vessels carrying deoxygenated back to heart, right aura
