muscle
10 of 27
What is a heart beat?

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
