Answer» Thanks ☺☺☺ Based on the way of secretion: Glands are two types based on secretion as1. Exocrine glands: They secrete into a location or region of the body through a duct and their secretions are called enzymes mostly while some are non enzymes.Types of exocrine glands and their secretions includeSalivary gland: In the buccal cavity secrete saliva. This saliva has many functions.Pancreas: Secretes enzyme amylase, trypsin and lipase. These enzymes digest carbohydrates, proteins and fats respectively.Sperm: Sperms produce Hyaluronidase an enzyme which helps it swim in the uterine tissue to reach ova. sweat glands: secrete sweat which acts to regulate body temperature and also excretion.Sebaceous gland: secrete sebum.Lachrymal glands: In eye secrete water to moisten the eye.Types of Glands2. Endocrine glands: Secrete into blood flowing through them, so as to let the secretion function at distant parts of the body from the gland. They are ductless glands. Their secretions are called as hormones.a) Pituitary Gland (of hypothalamus): This is a gland located below the hypothalamus in the brain.b) Thyroid gland: Produces thyroid hormones T3 & T4.c) Parathyroid gland: Produces parathormone.d) Adrenal gland: located on the two kidneys. It has outer cortex and inner medulla regions.e) Pancreas: Pancreatic gland has both exocrine and endocrine functions. It secretes multiple hormones which control body glucose metabolism. Its endocrine function release secretions like insulin, glucagon, somatostatin.f) Kidneys: produce Renin angiotensin (controls blood pressure).g) Pineal gland: Located inside the brain and called as body natural clock. One ca see jet-lag effects due to its secretions. Melatonin (sleep hormone). |
