Cardiovascular Final Boss Flashcards
What is heart rate
Hate rate - 60 -80 beats per mins, monitored by pulse ( accessible artery) in wrist or arm
What is stoke volume
The amount of blood that pumps by heart in one contract
- the volume of blood in ventricles before they contract
Average individual = 70 ml
Blood pressure
The force exerted by blood on vesssel wall
Systolic Bp- the pressure produced in the arterial system when the left ventricle contracts and pushes blood into the aorta
Diastolic BO - the pressure in the arteries when the heart is resting ( cardiac diastole )
The cardiac cycle
- As the atria and ventricles relax ( diastole ), they fill with blood from the vena fava and pulmonary vein
- The atria contracts ( systole) squeezing more blood into the ventricles
- Next the ventricles contracts, squeezing blood into the aorta and pulmonary vein
What is sympathetic nervous system and parasympathetic system
Sympathetic nervous system- speeds up heart heart for example exercise and stress ( aderline)
Parasympathetic system - slows down sleep or rest
What is actute ( sudden )
Chronic
Life threading
Short term diseases
Heart attack
Angina
Lukiema
Anemia
what is CHD
Fatty deposits in the arteries walls that stop blood circulations
- arteries become narrow
Lungs - wheezing , couphijg , due to lack of oxygen , heart pushes unesseary fluid to lungs
Obesity and diabesties pancreas - ENDORINe
what is stoke
Lack of blood flow that goes to the brain this could be because of a blood vessel that burst in the brain
- CNS- faintness, dinzinesssz, speech language motor skills
Circulatory lack of oxygen to the brain - brain dead
What is anemia
Anime is the lack of oxygen in RBC due to fewer so there is a lack of oxygen is muscles tissues
- muscle fatigue, hypotenia
Lung problems
What are ateries
Carry blood away from heart
Arteroles
Carry blood away from heart regulating blood flow
- provide a extensive network to supply capillaries
What are capliceries
Blood flow very slowly to allow nutrients to pass to and from waste into muscles and organs
What are veins
Carrys blood back into heart
