The cardiovascular system
Cards in this deck (18)
- 1What are the main components of the circulatory systemthe heart
the blood vessels
the blood - 2Define the term heart ratethe number of times the heart beats in a minute
- 3Define the term stroke volumethe amount of blood leaving the heart each beat
- 4Define cardiac outputheart beat x stroke volume
the amount of blood pumped by the heart in one minute - 5define resting heart ratethis is the heart rate when the body is at complete rest
- 6define recovery ratethe time it takes for the heart to return to resting heart rate
- 7define systolic and diastolic pressuremeasured by a sphygomomanometer
systolic - the pressure against the vessel walls when the heart is contracting
diastolic - the pressure against the vessel walls when the heart is relaxing ( in between beats) - 8state some short term effects of exercise on the cardiovascular system- increase in heart rate
- increase in systolic blood pressure
- increase in stroke volume
- increase in cardiac output - 9state some long term effects of exercise on the cardiovascular system- increase in size and strength of the heart ( cardiac hypertrophy)
- increase in stroke volume
- decrease in resting heart rate
- quicker recovery rate
- increased maximum cardiac output
- increased number of red blood cells
- increased capillerisation - 10What is the role of the cardiovascular system1. To transport oxygen in the blood to the working muscles
2. remove waste products
3. return the blood to the lungs for oxygenation - 11What is the equation for cardiac outputstroke volume x heart rate
- 12Which is normally lower systolic or diastolic blood pressurediastolic, because the blood flow is slower when relaxing - so there pressure is lower.
- 13What's an issue with too high blood pressureit can put strain on your arteries
- 14What are the effects of an unhealthy diet on the blood vesselsfatty deposits can build up in blood vessels, resulting in high blood pressure and high cholesterol.
- 15How many types of cholesterol are there?2
- 16What are the names for the two cholesterols(HDL) High Density Lipoproteins
- This is the good cholesterol that can take away cholesterol to be broken down
(LDL) Low Density Lipoproteins
- This is the bad cholesterol that causes deposits to build up in the arteries. This makes it harder for the blood to circulate. - 17How can long term exercise affect blood pressure and cholesterolIt lowers your blood pressure
It lowers your cholesterol levels. - 18What are the dangers of doing nothing to reduce your b.p or cholesterol levelsYou could suffer from stoke or coronary heart failure
