扫描电子显微镜图像一个中性粒细胞(黄色),吞噬了炭疽热细菌(橙色)。
扫描电子显微镜下,处于正常循环中的人类血液的图像。可以看到大量饼状的红血球,包括淋巴细胞、单核细胞、中性粒细胞在内的表面有突起的白血球,以及较小的盘状的血小板。
辅助型T细胞的功能:抗原呈递细胞将抗原呈递到细胞表面的II型MHC分子上,辅助型T细胞在其表面的CD4辅助受体(CD4+)的帮助下来识别这些抗原与MHC所形成的复合物。完成识别后,辅助型T细胞转变为活性状态,释放出细胞因子和其他激活信号(绿色箭头)从而激活巨噬细胞、杀伤型T细胞和B细胞,后者可以生产抗体。而激活B细胞和巨噬细胞可以进一步促进辅助型T细胞的增殖。
抗体分子由两条重链和两条轻链组成。重链和轻链上的可变区使得抗体可以识别不同的抗原。[59]

免疫系统是生物体体内一系列的生物学结构和进程所组成的疾病防御系统。免疫系统可以检测小到病毒大到寄生虫等各类病原体和有害物质,并且在正常情况下能够将这些物质与生物体自身的健康细胞和组织区分开来。

病原体可以快速地进化和调整,来躲避免疫系统的侦测和攻击。为了能够在与病原体的对抗中获胜,生物体进化出了多种识别和消灭病原体的机制。就连简单的单细胞生物,如细菌,也发展出了可以对抗噬菌体感染的酶系统。一些真核生物,例如植物和昆虫,从它们古老的祖先那里继承了简单的免疫系统。这些免疫机制包括抗微生物多肽(防御素)、吞噬作用和补体系统。包括人类在内的有颌类脊椎动物则发展出更为复杂多样的防御机制。典型的脊椎动物免疫系统由多种蛋白质、细胞、器官和组织所组成,它们之间相互作用,共同构成了一个精细的动态网络。作为复杂的免疫应答的一部分,人类的免疫系统可以通过不断地适应来更有效地识别特定的病原体。这种适应过程被定义为“适应性免疫”或“获得性免疫”。针对特定的病原体的初次入侵,免疫系统能够产生“免疫记忆”;当该种病原体再次入侵时,这种记忆就可以使免疫系统迅速作出强化的免疫应答(即“适应性”)。而适应性免疫正是疫苗注射能够产生免疫力的生物学基础。

A scanning electron microscope image of a single neutrophil (yellow), engulfing anthrax bacteria (orange)
A scanning electron microscope image of normal circulating human blood. One can see red blood cells, several knobby white blood cells including lymphocytes, a monocyte, a neutrophil, and many small disc-shaped platelets.
Function of T helper cells: Antigen-presenting cells (APCs) present antigen on their Class II MHC molecules (MHC2). Helper T cells recognize these, with the help of their expression of CD4 co-receptor (CD4+). The activation of a resting helper T cell causes it to release cytokines and other stimulatory signals (green arrows) that stimulate the activity of macrophages, killer T cells and B cells, the latter producing antibodies. The stimulation of B cells and macrophages succeeds a proliferation of T helper cells.
An antibody is made up of two heavy chains and two light chains. The unique variable region allows an antibody to recognize its matching antigen.[58]

The immune system is a system of many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. In many species, the immune system can be classified into subsystems, such as the innate immune system versus the adaptive immune system, or humoral immunity versus cell-mediated immunity. In humans, the blood–brain barrier, blood–cerebrospinal fluid barrier, and similar fluid–brain barriers separate the peripheral immune system from the neuroimmune system which protects the brain.
