Mechanism of blood pressure

1. Baroreceptors are neurones that can detect the changes in blood pressure. Baroreceptors are located at the acrh of the aorta.

2. When blood pressure decreases, baroreceptors are less stimulated. The decreased rate of nerve impulses are sent to the cardiovascular centre in the medulla oblongata. It results in stronger cardiac muscle contractions and increases the heartbeat rate, returning it back to the normal pressure. when blood pressure increases, baroreceptorsare more stimulated. the increased rate of nerve impulses are sent to the cardiovascular centre in the medulla oblongata.
It results in weaker cardiac muscle contractions and decreases the heartbeat rate, returning it back to normal.

I love dresses!




Recently I developed an interest in fashion.
Maybe is due to reading too much of Vivi magazine.
The bubbly and cheerful missy who is always wearing pants developed an interest in dresses?
You must be kidding man!!
But nothing is impossible right
maybe dresses will look nice on me
Just hope that mum will not think I am too weird for dresses
Actually i love dresses a lot
But I don't wear it so ''often'' is because of I did not have any casual dresses in my wardrobe
Moreover dresses are not cheap, they cost a bomb k!

Anyway I think dresses will make me look more feminine ==
So the next target is shopping for dresses!!

胆识过人???

当玻璃盘上的叉子指向我的时候
我问了大家, 我是不是一个有胆识的人
大家都给了近乎相同的答案
但是只有一个人给了我一个我想要的答案
他说他认为我是一个有勇气追寻梦想的人

我常常思考, 我到底能不能够独立, 适应未来要面对的种种
包括升学, 考车, 工作, 赚钱 等等
我好怕我会被时代淘汰, 不被世人认同

因此, 我告诉自己一定要勇敢, 就算害怕也要硬撑下去
唯有这样自己才会坚强起来
辩论比赛让我胆怯
但是我仍然硬着头皮撑下去
我知道只有勇敢一点才能在社会上生存

我的梦想就是靠自己的能力过很好的生活
拥有很好的家庭与事业
这种憧景 需要很多很多勇气来实现吧
其实 我很胆小的, 但是我知道唯有鼓起勇气才能成功
国晖, 你觉得我能够做到吗?

烟花

当人们第一次看到烟火时
惊叹声中不免参杂着兴奋与激昂
那惊叹赞叹着人类伟大的发明

当烟火徐徐升上天空
伴随着人类的梦想
绽放出漂亮的形状
绚丽的色彩

但你们不知道
当烟火绽放的时候
在我心里沉寂好久的热情
都会再次燃起
