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.

Oxygenated blood received from the vena cava, from the lungs

Question 7

What are the stages of the cardiac?

Answer 7

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

Question 23

When muscles are contracting what detects it and what happens to inmate movement?

Answer 23

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

Question 24

When the body has finished exercising what dos the body do to reduce the heart rate?

Answer 24

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
