Slide 1-

THE BLOOD VESSELS Blood Vessels Are they simple pipelines? (vascular system)
Slide 2-

CONTENT Overview of Vascular System Arterial Pressures and Flow Capillary Exchange Venous Blood Flow Regulation of the Vascular System Special Circulations
Slide 3-

H2O Glucose Lipids Amino acids Vitamines Minerals O2 Blood vessel External Environment Permeability of Blood Vessels ? Tissue cells
Slide 4-

Is blood vessel wall permeable everywhere? Arteries Veins Capillaries
Slide 5-

Distribution of Blood (at rest)

Predict the change in Ps and Pp in atherosclerosis
Slide 22-

- is the average pressure over the cardiac cycle MAP = Pd + 1/3 (Ps – Pd) Mean arterial pressure (MAP) systolic pressure (Ps) diastolic Pressure (Pd) 110 mmHg 80 mmHg - MAP = 80 + 1/3 (110 – 80) = 90 (mmHg)
Slide 23-

The pressure pulse disappears in capillaries.

BLOOD FLOW Definition: volume of blood moving through a blood vessel in a given time (ml/min) F =  P R P1 P2  P = P1 - P2 F
Slide 28-

Peripheral Resistance - opposition to blood flow due to friction between the blood and the blood vessel wall and among components of the blood heart 120 mm Hg 40 mm Hg Total vascular bed
