If you look closely at the cortex and medulla, you can see many tiny, tubular structures that stretch across both regions perpendicular to the surface of the kidney. In each kidney, there are one million of these structures, called nephrons. The nephron is the basic unit of the kidney. It's a long, thin tube that is closed at one end, has two twisted regions interspaced with a long hairpin loop, ends in a long straight portion and is surrounded by capillaries.
Improves Coordination. Jumping rope actually improves your coordination by making you focus on your feet. Whether or not youâre paying attention to them, your brain is aware of what your feet are doing.
Begin by jumping rope in place for 20 seconds, making sure your feet are balanced and you are landing on the balls of your feet. After 20 seconds, start jogging forward while continuing to jump over the jump rope. As you improve, increase the speed with which you are running forward and jumping. Perform for as long as you can, accelerating your speed until fatigued. High Knee Drill. High knee jump rope drills help improve your speed and strengthen your legs by forcing you to keep your knees high for an extended period of time. Start by jumping rope, bouncing from one foot to the other to establish a rhythm. Once your rhythm is established, increase the height of each knee as you jump over the rope.
