第节概述 感觉器官的感受装置称为感受器,感受器能接受 体内、外环境的各种刺激,然后将刺激所引起的兴奋 转化为神经冲动,通过传入神经到中枢,建立机体与 内、外环境之间的联系

Branch of discovery science focusing on proteins In 1994 defined as the complete set of proteins that is expressed and modified following expression by the entire genome in the lifetime of a cell. If we look at an organism it means that we are looking at the proteome of 3 trillion of cells and -1000

body. These organs can be classified functionally nto two main groups. The primary lymphoid organs provide appropriate microenvironments for the development and maturation of lymphocytes. The secondary lymphoid organs rap antigen from defined tissues or vascular spaces and are sites where mature lymphocytes can interact effectively with that antigen. Blood vessels and lymphatic systems connect these organs, uniting them into a functional whole Carried within the blood and lymph and populating the Macrophage Interacting with

All antibodies share struc
