exocrine/endocrine
| Question | Answer |
|---|---|
| exocrine glands | secrete chemical substances into ducts that lead either to other organs or out of the body |
| The structure of the exocrine glands is divided into two parts: | Ductal portion and glandular portion |
| ductile portion (of sweat gland) | is tubular in shape. It is a single, thick, cuboidal cell wall that helps in the movement of the secretion |
| glandular portion | is responsible for the production of the secreted substance. It is a circular or elongated cluster of cells. |
| functions of exocrine glands | Regulate body temperature,LubricationLactationHelps in digestionHelps in reproduction |
| types of exocrine glands | merocrine, apocrine, holocrine |
| merocrine glands | Exocrine glands that secrete without losing cellular material |
| appocrine glands | a sweat gland that secretes a viscous fluid into a hair follicle (as in the armpit or groin), is lined with a single layer of usually columnar cells with eosinophilic cytoplasm, and typically does not become active until puberty |
| holocrine glands | Exocrine glands whose secretions are made up of disintegrated cells |
| Lacrimal Glands- | include tear ducts near each eye. |
| Pancreas- | Secretes pancreatic juice along with the digestive enzymes into the stomach. |
| salivary glands | Glands of the mouth that produce saliva, a digestive secretion |
| Liver- | secretes bile that contains salts and digestive substances. |
| Mammary Glands- | secrete breast milk. |
| Eccrine Sweat Glands- | respond primarily to elevated body temperature by the release salty water through perspiration. |
| pancreatic gland | Regulates the level of blood sugar in the blood |
| Pancreas | is the largest exocrine gland which is 99% exocrine and 1% endocrine. |
| endocrine glands | Glands of the endocrine system that release hormones into the bloodstream |
