The basement membrane is an example of extracellular matrix, the subject of the next lecture.
Insulin is made by the pancreas and facilitates the movement of glucose from the blood and extracellular fluids into the cells.
Phagocytosis is an uptake mechanism based on a complex rearrangement of the actin cytoskeleton that delivers large extracellular particles into intracellular vacuoles.
The result of this is to decrease urine volume and increase the volume of extracellular fluid.
Many of them, probably also of proteid nature, are much more resistant to heat; thus the intracellular toxins of the tubercle bacillus retain certain of their effects even after exposure to iooÃ‚° C. Like the extracellular toxins they may be of remarkable potency; for example, fever is produced in the human subject by the injection into the blood of an extremely minute quantity of dead typhoid bacilli.
