cardiovascular disease

Question 1

what is atherosclerosis

Answer 1

• plaque build up in the arteries
• makes them swell and stiff
• reduces the lumen diameter of the artery

Question 2

what could atherosclerosis lead to

Answer 2

• blood clots forming
• a heart attack/ stroke

Question 3

what is plaque made from

Answer 3

• white blood cells
• cholesterol
• fat

Question 4

what could an atherosclerosis be created from

Answer 4

• high blood pressure
• toxin releasing from tobacco when smoking

Question 5

why would high blood pressure cause an an atherosclerosis

Answer 5

the high pressure puts strain on the arterial walls

Question 6

stage 1 of an atherosclerosis formation

Answer 6

• the squamous endothelium lining is damaged

Question 7

stage 2 of an atherosclerosis formation

Answer 7

• macrophages travel to the damaged vessel and accumulate material here such as cholesterol
• the accumulation of the cholesterol build ups

Question 8

stage 3 of the atherosclerosis formation

Answer 8

• the accumulation attracts more material build around the cholesterol
• the atheroma grows and hardens over time
• the atheroma grows and reduces the lumen diameter of the artery
• restricts the volume of blood flow through the artery
• the atheroma now becomes plaque

Question 9

stage 4

Answer 9

• atheroma grows
• fibrous tissue builds up more
• reduces elasticity of the artery
• now artery cant vascoconstrict/ dilate to regulate blood flow

Question 10

stage 5

Answer 10

the results of the atheroma formation
- reduces elasticity and narrow lumen
- harder for blood to flow through
- blood pressure increases
- high blood pressure increases likelyhood of another atheroma forming

Question 11

what is thromosis

Answer 11

the formation of blood clot in a damaged blood vessel
