概括
的硬的外显著影响他们的呼吸机制. 具有弹性外的幼与具有刚性外的成年人相比,具有不同的呼吸动态.
科学领域:
- 比较生理学比较生理学
- 脊椎动物的呼吸机制
- 切洛尼亚生物学的生物学.
背景情况:
- 类动物 (海和海) 具有独特的,硬的外,影响呼吸系统机制.
- 骨化和内脏质量的本体遗传变化可能会改变呼吸效率.
- 了解这些变化对于理解龙呼吸系统生理学至关重要.
研究的目的:
- 为了研究红脚 (Chelonoidis carbonarius) 在本体生殖过程 (青少年与成年人) 中的呼吸机制.
- 评估身体位置 (仰卧,俯卧) 和内脏质量对呼吸系统参数的影响.
- 为了比较完整的海与孤立的肺部中的呼吸机制.
主要方法:
- 测量包括静止肺体积 (VLr),最大肺体积 (VLm),静态遵守 (Cstat),动态遵守 (Cdyn) 和呼吸工作 (W).
- 研究对青少年和成年C. carbonarius在不同的身体位置和孤立的肺部进行了研究.
- 分析了数据,以评估对呼吸功能的遗传学,定位和内脏影响.
主要成果:
- 与完整的动物相比,孤立的肺部显示体积增加,服从,呼吸工作减少.
- 身体位置影响了肺体积,在仰卧姿势中观察到较小的VLr.
- 青少年的每人体质呼吸工作低于成年人,但每个休息肺体积的呼吸工作类似.
结论:
- 青少年和成年C. carbonarius之间存在呼吸机制的显著本体遗传差异,主要归因于骨化.
- 内脏质量和肺隔膜后发育程度也可能导致这些观察到的差异.
- 贝的刚性在塑造呼吸系统的机械性质中起着至关重要的作用,在乌的整个生命中.

01:17Gross Anatomy of the Lungs

The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
