Study Notes
Cardiovascular System
- Arteries have thick walls to withstand pumping blood pressure.
- Veins have thinner walls due to less blood pressure.
- Capillaries act as a bridge between arterioles and venules.
Blood Flow and Composition
- Veins carry blood that is low in oxygen and high in carbon dioxide.
- Capillaries allow the exchange of oxygen for carbon dioxide and nutrients for waste products.
Electrocardiogram (ECG/EKG)
- ECG/EKG is a graphic record of heart's electrical activity.
- The P wave in an ECG represents the activity of the atria.
Heart Rate and Rhythm
- Heart rate is the number of heartbeats per minute.
- Bradycardia is a condition where the heart rate is less than 60 beats per minute.
- Veins flow blood back towards the heart.
