Elasticity of Pulmonary Blood Vessels in Human Lungs volume in response to an alteration in blood pressure. In order to formulate such problems, mechanical property data for blood vessels of all generations of the human lung are needed and are gathered in our laboratory. In particular, vessel diameter as a function of transmural pressure are measured for each vessel generation.作者: 肌肉 時(shí)間: 2025-3-24 22:40 作者: 保存 時(shí)間: 2025-3-24 23:20 作者: macrophage 時(shí)間: 2025-3-25 04:19
