如是细小的泡沫则是原料未洗透彻或不太新鲜,建议在初次煮锅内放些料酒。待开锅后再换一次新水来炖煮。

求英文答案 !!!
when we breathe in (inspiration)
the diaphragm muscle contracts and bee flattened
the external intercostal muscles also contract to move the rib cage upwards and ouards. both will cause an increase in thoracic volume. the pressure in thoracic cavity decrease and bee lower than atmospheric pressure. Thus air from atmosphere rush into the lungs and the lung is inflated. when we breath out (expiration)
the diaphragm muscle relax and cause it bee dome-shaped. the external interconstal muscle also relax and cause the rib cage move inwards and downwards. both cause a decrease in thoracic volume. the pressure in thoracic cavity increase and bee higher than the atmospheric pressure. thus air is forced out from the lungs and the lung bee deflated. athletes&#39lungs aren&#39t bigger
but their tidal volume and vital capacity will be larger than us due to their training. so they can breathing volume will be greater to facilitate gaseous exchange (O2 and CO2) to support the energy need for and remove wastes from exercise.

从外界空气中吸入氧,使氧气进入肺部血液,再运输到身体各部份使用。另一方面,肺部血液里的二氧化碳则渗透到气泡里,再排出体外。 横隔膜帮助呼吸人的肺脏普遍右肺宽而短,左肺窄而长。两肺之间有心脏和大血管、气管、食道等器官。肺的下面被膈与腹腔脏器隔开。 肺的表面有浆膜(即脏胸膜),光滑、湿润。肺柔软而有弹性,肺内含有空气,呈海绵状。肺的颜色随年龄和职业而有所不同,新生儿的肺为淡红色;成人由于不断吸入尘埃,沉积于肺而呈暗灰并有黑色斑点;老年人颜色更黑。 [编辑] 呼吸原理 外肋间肌 收缩 放松 内肋间肌 放松 收缩 肋骨和胸骨移动方向 外、上 内、下 横隔膜肌 收缩 放松 横隔膜 扁平 拱形 胸腔容量 大 小 胸腔压力 小 大 肺部 扩张 缩小 肺内气压 低 高 效果 吸气 呼气 [编辑] 中医 中医认为「肺主气,心主血,气为血之帅」、「肺朝百脉,助心行血」,指肺能使百脉之气血如潮水般有规律地周期运行。 [编辑] 其他动物的肺脏 爬虫类动物的肺像一个大气泡(bellows)一样; 鸟类的肺又名循环肺; 鱼类的肺只能让血单向的流动。 2007-04-13 16:54:40 补充: In air-breathing vertebrates
respiration occurs in a series of steps. Air is brought into the animal via the airways — in reptiles
birds and mammals this often consists of the nosethe pharynxthe larynxthe trachea (also called the windpipe)2007-04-13 16:55:40 补充: the bronchi and bronchiolesand the terminal branches of the respiratory tree. The lungs of mammals are a rich lattice of alveoli
which provide an enormous surface area for gas exchange. A neork of fine capillaries allows trport of blood over the surface of alveoli. 2007-04-13 16:55:49 补充: Oxygen from the air inside the alveoli diffuses into the bloodstream
and carbon dioxide diffuses from the blood to the alveoli
both across thin alveolar membranes.

肺气泡和肺气肿跟宠物没有关系的肺气肿病者的饮食营养疗法首先是安排好进食环境。例如,在进食前适当休息以减少缺氧。如果病情重者,在进食前和进食之后应吸氧3--5分钟。这是因为进食时耗量增加,需要补充吸氧量,但在进食时则不能吸氧,如进食和吸氧同时进行,一则易发生食物误吸入气道,二则吸氧无效,因为进入鼻腔内的氧气会 随咀嚼动作经口腔排出。为何在进食之后吸氧呢?这是因为进食 之后,胃内容物增加,腹压上升,使隔肌位置上移,肺容量减少, 增加缺氧,进食后吸氧可以缓解由于进食动作而产生的缺氧症状。
鉴于上述原因,肺气肿病人应少食多餐,软食为主。其次要安排好食谱,蛋白质和碳水化合物(糖类和淀粉类)每克含4卡热量,对一般病情不重的肺气肿病者,补充此类食品是适宜的。但如病重出现呼吸困难者,不宜进食蛋白或糖类(淀粉)比例过多的食 品,否则会加重呼吸困难,原因是蛋白质食物过高会刺激呼吸中柩兴奋,呼吸急促症状增加,而淀粉或糖分过高食品可使体内 CO2产生增多,加速体内CO2潴留。此时最好进食含脂肪比例高的食品,而且脂肪每克热量达9卡之多,对患者热量补充有利。 补充维生素,多吃新鲜蔬菜或水果对肺气肿病者
