Being free from disease 1 of 27 What is fitness Ability to do physical exersize 2 of 27 What are some ways of measuring fitness? Blood pressure/ Breathing rate/ Pulse recovery time 3 of 27 What is strength? How is it measured? Amount of weight lifting/ weight lifting 4 of 27 What is flexability? How is it measured? Ammount of joint movement/ sit and reach test 5 of 27 What is speed/ How is it measured? covering an amount of distance in a short amount of time 6 of 27 What is agility? how is it measured? Ability to change direction many times/ 20m shuttle run 7 of 27 What is the role of the heart? pumps blood around body 8 of 27 What is the structure of the heart? A system of valves/ 4 chambers/ covering artery 9 of 27 What is the heart made from? muscle 10 of 27 What is a heart beat? one complete contraction of the heart 11 of 27 What is a coronary artery? Vessels of blood to the heart muscle/ supplies heart muscle with 02, and glucouse 12 of 27 What do arteries carry? Blood under pressure 13 of 27 What is blood pressure? Force from the blood to the walls of the vessels 14 of 27 How does one measure blood pressure? Systolic pressure//diastolic pressure per mmmHg 15 of 27 What is the role f the red blood cell? Yransports oxygen/ transports carbon dioxide/ moves waste/ transports nutriants 16 of 27 Factors that increase blood pressure are... Smaoking, being over-weight, stress, high salt diet, high alchole intake 17 of 27 Factors that decrease blood pressure are... regular exersize, balanced diet 18 of 27 What is hemoglobin? a substance in red blood cells that attracts and absorbs oxygen 19 of 27 How does CO affect the role of hemoglobin? CO reduces amount of oxygen carrying capacity of the blood as CO takes up space in the red blood vessels as hemoglobin absorbs co easier than o2 20 of 27 how does niotine increase blood pressure? Nicotine is a stimulent so affects nerves that control the size the blood vessels/ make them narrow, increasing blood pressure 21 of 27 What is vasconstriction? When blood vessles narrow 22 of 27 What is cholesterol When saturated fat builds up in arteries/ blood flows though arteries at high pressure 23 of 27 What happens to ones body if one has a diet high salt? increase in blood pressure= heart disease 24 of 27 What are the main consequences of high blood pressure? small blood vessles bursting in brain=stroke=brain damage/paralysis. Small blood vessels bursting in kindny=kidney failier 25 of 27 What is thrombosis Clotting of blood in a vessels,causing a blockage 26 of 27 What are the consequences of low blood pressure? low circulation/ dizziness 27 of 27
