What are the general characteristics of the cardiovascular system?
• Flow: depends on ability of heart to pump
• Size: adult fist (300 grams)
• Pump rate: 60-70 bpm
• Volume: 70 ml per beat (5 liters per minute)
What materials are carried/found in the blood?
•Oxygen
• Nutrients
• Wastes
• Hormones
• Immune cells
What is cardiac output?
•The heart is the pump that moves the blood.
,•Its activity can be expressed as "cardiac output (CO)"
•In reference to the amount of blood moved per unit of time.
CO=HR x SV
What factors affect cardiac output?
•Factors effecting CO
-Anatomy
-Physical mechanisms
-Blood supply to heart
Which side of the heart pumps to the systemic circulatory system?
•Systemic circulatory system
- Left side of heart
What side of the heart pumps to the pulmonary circulatory system?
•Pulmonic circulatory system
- Right side of heart
, What is systole?
Contraction of the heart
What is diastole?
Relaxation of the heart
What is the cardiac cycle?
•Sequence of events associated with one complete cycle of contraction and
relaxation of the heart
How long does the cardiac cycle last?
0.8 seconds
How long is ventricular systole?
0.3 seconds
How long is ventricular diastole?
0.5 seconds
