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.
Skip it! Jumping rope burns more than 10 calories a minute while strengthening your legs, butt, shoulders, and arms. And it doesnât take long to reap major rewards. You can burn more than 200 calories in two, 10-minute sessions each day (that's 1,000 calories a week)! Jumping rope is also a great way to fit in an effective cardio session when you're on the go; just toss it in your carry-on! You'll probably feel completely energized after jumping rope too.
