Question

fill in the blanks with the terms provided. not all terms will be used. 1. within systemic capillaries, substances such as oxygen, hormones, and nutrients move by high from their relatively hormones concentration in the blood into the interstitial fluid and then in (click to select) where the concentration of these materials is (click to select). very small solutes and fluids may p while larger solutes, must pass through the fenestrations in (click to select) or gaps in capillaries. endothelial cells may use (click to select) to fuse fluid - filled vesicles with the plasma membrane. th move contents either from the blood to the interstitial fluid or from the interstitial fluid into endothelial cells such as certain (click to select) and fatty acids are transported across the endothelial cells by this meth exocytosis high hormones low pinocytosis sinusoids vesicular transport

Explanation:

Substances like oxygen, hormones, and nutrients move from an area of high concentration in the blood to an area of low concentration in the interstitial fluid by diffusion. Very small solutes and fluids may pass through fenestrations in endothelial cells or gaps in capillaries. Larger solutes may use vesicular transport (such as exocytosis or endocytosis - here exocytosis is relevant for moving from blood to interstitial fluid) to move contents. Fatty acids can be transported across endothelial cells by pinocytosis.

Answer:

1. high
2. low
3. endothelial cells
4. exocytosis
5. pinocytosis
