To help move oxygen-rich blood from the lungs to all parts of the body, your arteries have thick layers of muscle or elastic tissue. To push blood back to yourheart, your veins rely mainly on surrounding muscles and a network of one-way valves. As blood flows through a vein, the cup-...
Any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood towards the heart. Vessel A duct or canal holding or conveying blood or other fluid. Vein A fracture in rock containing a deposit of minerals or ore and typically having ...

10.2.3.1Blood Flow Transport Transport of drug molecules by flowing blood is an obvious example of convective transport. The heart pressurizes the blood causing it to flow through the pulmonary and systemicvasculature. The arterial portion of thesystemic circulationdelivers oxygen-rich blood, as well...
The rapid increase in hepatic portal venous blood flow into the non-embolized lobe increases shear and circumferential stress on sinusoidal endothelial cells, hepatocytes, and Kupffer cells, initiating a cascade of signaling events that leads to an increase in pro-proliferative cytokines (e.g., ...
They carry relatively deoxygenated blood from the fetus, via the internal iliac arteries, to the placenta with its branching villous tree, where oxygen and nutrient exchange can occur. Replenished blood then returns to the fetus via the single umbilical vein, which typically has a larger luminal ...
