Angiogenesis
Description
Angiogenesis is the biological process through which the body grows new blood vessels from existing ones, triggered by chemical signals released from tissues in need of oxygen. Understanding this mechanism is vital to our comprehension of wound healing, as well as the way cancerous tumors nourish themselves and spread throughout the body.

אנגיוגנזה
תהליך האנגיוגנזה מאפשר לגוף להצמיח כלי דם חדשים מתוך כלי דם קיימים בתגובה לאותות כימיים המופרשים מרקמות הזקוקות לחמצן. הבנת המנגנון הזה חיונית להבנת תהליכי ריפוי פצעים, אך גם להבנת האופן שבו גידולים סרטניים מזינים את עצמם ומתפשטים בגוף.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
