substances in blood plasma become enclosed within tiny pinocytic vesicles that first enter endothelial cells by endocytosis, then move across the cell and exit on the other side by exocytosis.

a passive process in which large numbers of ions, molecules, or particles in a fluid move together in the same direction

Pressure-driven movement of fluid and solutes from blood capillaries into interstitial fluid

Pressure-driven movement frominterstitial fluid into blood capillaries

the volume of blood that flows through any tissue in a given time period

cardiac output (CO), the volume of blood that circulates through systemic (or pulmonary) blood vessels each minute

2 ways to calculate cardiac output

is the opposition to blood flow due to friction between blood and the walls of blood vessels.

3 factors affect vascular resistance

the volume of blood flowing back to the heart through the systemic veins, occurs due to the pressure generated by contractions of the heart's left ventricle
