Sinoatrial Node?
Explanation:
Blood pressure drops whenever the vagus nerge is stimulated. In fact, babies have to constantly be monitored for position, becase cranial pressure can stimualte the vagus nerve and cut heart circulation by inhibitng the Sinoatrial node.
So we all know that the Earth rotates around the Solar system all the time nonstop. But wait there is more. One half of the Earth which is North America and South America are faced to the sun so you can tell that we are in summer. While we are in summer,the other half of the Earth which is Europe,Africa,Asia and Austrialia ( I think I spelled that wrong who cares about that) they are in winter. This process continues nonstop there is no break.
This means that they each have there own part in the cell, think baseball team. there are different players but you work together
The sun is extraordinarily hot because it is a star. Additionally, each star has its own unique, incredibly hot processes. These reactions are referred to as thermonuclear fusion. The Sun appears to be enormous in comparison to other stars due of its proximity to us. The Sun is a star of medium size. For instance, the following is a list of some of the biggest stars in our galaxy and their distance from the Sun: Mu Cephi is approximately 1500 times the diameter of our sun. The sun's core is so heated and pressurized that nuclear fusion occurs, converting hydrogen to helium. Nuclear fusion generates energy in the form of heat and photons (light)... Solar heat and light are sufficient to illuminate Earth's days and keep our planet warm enough to support life.
