Arteries |
Are strong elastic vessels that are adapted for carrying blood away from the heart under high pressure these vessels subdivide into progressively thinner tubes and eventually give rise to fighter branched arterioles. |
|
|
Veins |
Venules are the microscopic vessels that continue from capillaries and merge to form veins. the veins which carry blood back to the artery follow Pathways that roughly parallel those of the arteries. |
|
|
Systolic pressure |
The maximum pressure during ventricular contraction |
|
|
Capillaries |
The smallest diameter blood vessels connect the smallest arterioles and the smallest venules. capillaries are extensions of the inner lining of arterioles and that their walls are composed of endothelium. |
|
|
Diastolic pressure |
When the ventricles relax (ventricular diastole) the arterial pressure drops and the lowest pressure that remains in the arteries before the next ventral contraction is termed the diastolic pressure |
|
|
Blood volume |
Blood volume equals the sum of the formed elements and plasma volumes in the vascular system. about 5 liters for adults or 8% of the body weight in kilograms |
|
|
Blood viscosity |
Viscosity is the ease with which a fluid's molecule flow past one another. The greater the viscosity the greater the resistance to flow. |
|
|
Hypertension |
High blood pressure is persistently elevated arterial pressure. It is one of the more common diseases of the cardiovascular system in the industrialized nations. |
