Andru [333]
 The average red blood cell lives for 120 days.

2. There are 2.5 trillion (give or take) of red blood cells in your body at any moment. To maintain this number, about two and a half million new ones need to be produced every  second by your bone marrow.That's like a new population of the city of Toronto every second.

3. Considering all the tissues and cells in your body, 25 million new cells are being  produced each second.That's a little less than the population of Canada - every second !

4. A red blood cell can circumnavigate your body in under 20 seconds.

5. Nerve Impulses travel at over 400 km/hr (25 mi/hr).

6. A sneeze generates a wind of 166 km/hr (100 mi/hr), and a cough moves out at 100 km/hr(60 mi/hr).

7. Our heart beats around 100,00 times every day.

8. Our blood is on a 60,000-mile journey.

Dafna1 [17]

whenever one turns the pages of a book, uses a pen to take notes, or raises one's hand, one's actions are made possible by the somatic nervous system.

The somatic nervous system, also known as the voluntary nervous system, is the area of the peripheral nervous system that controls skeletal (voluntary) muscles to control body movement. It also connects the organism to its environment by receiving external stimuli through the senses of sight, hearing, taste, and smell. In contrast to the autonomic nervous system, which functions largely independently of conscious control in innervating heart muscle and exocrine and endocrine glands, the somatic nervous system uses efferent motor nerves to govern voluntary actions like walking and smiling.
