Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
Oxyphil cells have also been shown to have higher oxidative and hydrolytic enzyme activity than chief cells due to having more mitochondria. [2] Oxyphil cells have significantly more calcium-sensing receptors (CaSRs) than chief cells. [13] More work needs to be done to fully understand the functions of these cells and their secretions.
Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism . [ 1 ] Animal cells , plant cells and microorganism cells show similarities in their functions even though they vary in structure.
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
Cells adjust their pH i accordingly upon an increase in acidity or basicity, usually with the help of CO 2 or HCO 3 – sensors present in the membrane of the cell. [3] These sensors can permit H+ to pass through the cell membrane accordingly, allowing for pH i to be interrelated with extracellular pH in this respect.
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function.The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive.
The lymphatic endothelium refers to a specialized subset of endothelial cells located in the sinus systems of draining lymph nodes.Specifically, these endothelial cells line the branched sinus systems formed by afferent lymphatic vessels, forming a single-cell layer which functions in a variety of critical physiological processes.
