Cellular physiology is the study of how cells function and interact with each other within living organisms. This field of research encompasses a wide range of topics, including cell structure and organization, cellular metabolism, cell signaling, communication between cells, and cell growth and division. By studying cellular physiology, researchers aim to gain a better understanding of how cells maintain homeostasis, respond to their environment, and carry out specific functions within the body. This knowledge is essential for advancing our understanding of various biological processes and diseases, and for developing new treatments and therapies.
