These glial cells facilitate brain homeostasis, form myelin and provide neuronal structure and support8, consistent with evidence of RNA transport across and the permeability of the blood–brain barrier16,17 and that some brain regions are in direct contact with the blood18. Similarly, we used ...

We show here that taxol has different effects on different ...
The evaporation of water from the stomata is the main driving force for water transport through the water. In roots, epidermal cells have a specialized structure that facilitates water and nutrient absorption, the main function of the root. Some of the root epidermal cells have long membranous ...

Figure 14.Blood is a connective tissue that has a fluid matrix, called plasma, and no fibers. Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide. Also present are various leukocytes (white blood cells) involved in immune respo...
aquaporin 4 must regulate that ensheathment, because aquaporin 4 knockout mice had ~ 60% less coverage of cerebral capillaries by astrocytic processes; for that reason, astrocytes regulate water permeability and, therefore, the transport of drugs across the blood–brain barrier (BBB) [10]. ...

Transpiration in Biology Water is absorbed from the soil through plants' root hairs. The root hairs have a higher concentration of salt and less water than the soil around them, which causes the transfer of water to the roots through osmosis. Osmosis is the process by which water moves from...
