Pores are found in various tissues throughout the body. In the skin, they are primarily associated with hair follicles and sweat glands, playing a crucial role in thermoregulation and excretion. In the kidneys, pores in the glomerulus and renal tubules facilitate filtration and reabsorption. In the lungs, alveolar pores (pores of Kohn) help in the distribution of air and prevention of alveolar collapse.
