1 In a solution of potassium hydrogen iodate [KH(IO 3) 2 ] at 0.02 M the activity is 40% lower than the calculated hydrogen ion concentration, resulting in a much higher pH than expected.
This type of multicellular exocrine gland has a branched rounded secretory part attached to a single unbranched duct and is found mainly in sebaceous glands. simple branched acinar gland. simple tubular exocrine glands have. a straight tubular secretory portion attached to a single unbranched duct.his type of multicellular exocrine gland has a branched rounded secretory part attached to a single unbranched duct and is found mainly in sebaceous glands. simple branched acinar gland. simple tubular exocrine glands have. a straight tubular secretory portion attached to a single unbranched duct.
Sweat glands are probably the most familiar tubular glands. Other tubular glands include gastric glands (in the lining of the stomach), uterine glands, and various mucous glands of the GI system. Because tubules are elongated, random sections commonly include the lumen as well as the secretory cells themselves (in contrast to the situation with acini).
