Virchow was correct when he concluded that cells arise from others cells, i.e., new cells are born through the division of one cell into two through the process of mitosis. The need for new cells continues throughout our lives, but it is greatest in early life. A fertilized egg divides into two cells, which give rise to four, and those give rise to eight, and then to 16, and 32, and 64, and so on. In a fully grown adult, of course, the rate of cell proliferation is much less, and under normal circumstances, cell division in an adult takes place only when signals indicate the need to replace cells that have been lost, damaged, or worn out. Basically when your young so is your cell and ask you get older they get stronger
All of the systems that are aroused by the <span>sympathetic nervous system</span> are relaxed by the parasympathetic nervous system.
<span>autonomic nervous system (ANS) is a part of the central nervous system that controls all parts that the human cannot have a control on (which are done automatically) like heart rate and breath
ANS is divided in two opposite systems: sympathetic and parasympathetic:
</span>Parasympathetic nervous system: caracterized by the tag "<span>rest and digest" it decreases the heart rate, blood pressure, and breath. It increases the gastrointestinal motricity, letting the organism resting (this happen after a meal).
</span>Sympathetic nervous system: caracterized by the tag "fight or flight" it increases the heart rate, blood pressure, and breath. It decreases the gastrointestinal motricity, letting the organism focus on its environment (this happen when we are in danger).
