Tell me something ineresting?

Question

Tell me something about the human body that it does or something about how it works.. Like for EG Can you tell me what the liver does and how or can you tell me something about white blood cells

Please I am really interested about th body and want to know

Answer 1

The appendix is not useless as most believe. It's actually a little safe house for all the helpful bacteria in out intestines. It's designed to keep f***s out but let bacteria in so when something happens to flush out the intestines, like an illness, all the helpful bacteria you had before can happily repopulate.

Answer 2

no you can't make me

Answer 3

The Liver is a large organ in the body that stores and metabolizes nutrients, destroys toxins and produces bile. Responsible for thousands of biochemical reactions; This livestock organ used as food; A dark brown colour, tinted with red and grey.

have a nice day

Answer 4

Ok, here's one for you most people don't know too much about. Most, if not all, organisms here on Earth have endogenous circadian rhythms, meaning that they have natural daily biological rhythms that vary at nearly 24 hour cycles. In humans the suprachiasmatic nucleus (a collection of  ~20,000 bilateraly distrbuted neurons of the hypothalamus) is considered the central pacemaker, or master control for our body's circadian rhythmicity. One commonly identified function of our physiology that is dependent upon circadian rhythmicity is our sleep/wake cycle, however, physiological processes such as digestion, body temperature, and internal organ fuctions are all associted with circadian processes.

Now, this rhythmicity is not endogenously 24 hours on the button, rather it is slightly longer (on average 24 hours, six minutes). Thus our body incorporates external cues to 'reset' our circadian rhythms on a daily basis. For example, the retinal ganglions (nerves) that innervate upon the hypothalamus do directly so at the suprachiasmatic nucleus. Think of this model as a gate. At a certain time every day, it becomes important for a gate to open and let out the people behind the gate, in order for them to communicate information to the others in the rest of the neighborhood, so that the entire neighborhood runs most efficently. In the case of the suprachiasmatic nucleus, the gate is the inhibition of protein/gene synthesis, and the rhythmic synchronicity of our body is a function of these genes being expressed at specific times during the day. When our alarm clocks go off and light hits our photoreceptors in our eyes (not just rods and cones but also melanopsin receptors), this information 'resets' the suprachiasmatic nucleus, thus allowing the 'gated' expression of genes in order to consistantly synchronize the distal peripheral circadian clocks throughout out bodies on a daily basis.

Here is a neat example that ties these unifying themes together. Most of us, at one time or another, have woken up a couple of minutes before the alarm goes off on a regular basis (for me it was 5:58 am, every day). We do this, even when one night we go to bed at 10pm and the next night at 1:30am. Because our body has an accurate circadian pacemaker that resets itself once a day (to preserve stated accuracy), our central nervous system can consistantly decrease our body temperature throughout the course of the night (at consistant times, regardless of when we fall asleep), and when these temperatures decrease to a set point (for the purposes of this example, lets say 98.225 degrees Farenheit), our reticular activation system is signaled and we awaken at a constant time on a daily basis, all as a function of the rhythmic expression of genes from the suprachiasmatic nucleus.
