Capillaries (May 3, 2011)
Description
Capillaries are the smallest blood vessels in the body, serving as the vital site where gases and nutrients are exchanged between the blood and tissue cells. In this video, we take a close-up look at the flow of blood through these capillaries. We will see how red blood cells navigate these narrow passageways, driving the essential process that enables cellular respiration and ensures the proper functioning of the body’s organs.
Original title
נימים (3 במאי 2011)
הנימים הם כלי הדם הקטנים ביותר בגוף, ודרכם מתבצע חילוף הגזים וחומרי המזון בין הדם לתאי הרקמות. בסרטון נצפה מקרוב בזרימת הדם בנימים ונראה כיצד עוברים תאי הדם האדומים בקוטרם הצר, בתהליך שמאפשר את נשימת התאים ותפקודם התקין של האיברים השונים.

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
