This process is called photosynthesis. Cytoplasm is the gel-like material inside the cell membrane and. outside the nucleus. Cytoplasm contains a large amount of water and many chemicals. and structures that carry out the life processes in the cell. These. structures that the cytoplasm contains are called organelles.
Macrophages (Greek: big eaters, from Greek Î¼Î±ÎºÏÎ¿Ï (makros) = large, ÏÎ±Î³ÎµÎ¹Î½ (phagein) = to eat) are a type of white blood cell that engulfs and digests cellular debris, foreign substances, microbes, cancer cells, and anything else that does not have the types of proteins specific to healthy body cells on its surface in a process called phagocytosis.
Once activated by microbial products, macrophages acquire microbicidal competence that usually leads to effective immunity (2). However, several bacterial pathogens have evolved strategies to interfere with macrophage activation and to modulate host responses (3). Macrophages are dynamic and heterogeneous cells; this is due to different mechanisms governing their differentiation, tissue distribution, and responsiveness to stimuli (4, 5).
