30.
Differences Between Blood
Vessel Differences Between Blood Vessel Types Types Walls of arteries are the thickest Lumens of veins are larger Skeletal muscle “milks” blood in veins Slide 11.30 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Skeletal muscle “milks” blood in veins toward the heart Walls of capillaries are only one cell layer thick to allow for exchanges between blood and tissue
31.
Movement of Blood
Through Movement of Blood Through Vessels Vessels Most arterial blood is pumped by the heart Slide 11.31 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Veins use the milking action of muscles to help move blood Figure 11.9
32.
Capillary Beds Capillary Beds
Capillary beds consist of two types of vessels Slide 11.32 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings types of vessels Vascular shunt – directly connects an arteriole to a venule Figure 11.10
33.
Capillary Beds Capillary Beds True
capillaries – exchange vessels Oxygen and nutrients cross to Slide 11.33 Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings nutrients cross to cells Carbon dioxide and metabolic waste products cross into blood Figure 11.10
