LIVER
FUNCTION:- It secretes bile, which helps in the digestion of fats.
TYPE:-It is an exocrine gland because bile is released into a duct (the bile duct) and not directly into the blood.
Other roles:- Detoxificaion, storage of vitamines, metabolism of carbohydrates, proteins and fats.
PANCREAS- Both endocrine and exocrine
EXOCRINE FUNCTION :- Secretes digestive enzymes (like amylase, lipase, trypsin) into the duodenum via the pancreas duct.
ENDOCRINE FUNSTION :- Secretes hormones like insulin and glucogon into the bloodstream, which regulates the blood sugar levels.
TYPE :- It is a mixed gland (both exocrine and endocrine).
SKIN
The skin is the largest organ of human body.
Made up of layers: epidermis, dermis, hypodermis.
Contains glands, nerves, blood vessels and hair follicles.
FUNCTION:- Protection, temperature regulation, sensation, etc.
SWEAT GLANDS (inside the skin)
Yes, these are actual glands.
Part of the exocrine gland system.
They produce sweat which is secreted through ducts onto the sin surface.
Type of sweat Glands:
Eccrine glands – All over the body (esp. palms, soles, forehead)
Apocrine glands – Armpits, groin, around the nipplies
EYES
Lacrimal Glands- Tear-Producing Glands
Located above each eye, just under the upper lid.
They are exocrine glands that produce tears.
Tears help:
Lubricate the eye, Wash away dust and microbes, Provide Oxygen and nutrients to the cornea.
Lacrimal gland secretes watery part of tears (main tear gland)
Meibomian glands – Line the eyelids; secrete oil to prevent evaporation of tears
Glands of Zeis – Sabaceous glands at eyelash base
Glands of Moll – Sweat glands near eyelashes
Yes, the eye contain glands. Tears are secreted by the Lacrimal glands, making them exocrine secretions.
MOUTH
SALIVARY GLANDS :- Exocrine glands. They secrete saliva, which helps in: Moistening food. Beginning digestion ( With enzymes like amylase). Cleaning the mouth. Protecting the teeth.
Parotid- Near ears(Largest)-Watery Enzyme rich saliva
Submandibular- Below jaw- Mixed (watery + mucus)
Sublingual- Under the tongue- Mostly mucus
NOSE
NASAL GLANDS:- SEROMUCUS GLANDS – EXOCRINE GLANDS
They produce, Mucus: traps dust, microbes, and allergens. Serous fluid:- Keeps Nasal lining moist.
These glands are located in the nasal mucosa (lining inside the nose). They work with goblet cells ( special mucus-secreting cells) to: Humidify inhaled air . Defend against infection.
EARS
CEREMINOUS GLANDS :- In external auditory canal (outer ear). Modified sweat glands. Secretion- Cerumen (Ear wax).
FUNCTION :- Traps dust and microbes, Prevents drying of ear canal skin, Protects against bacterial or fungal infections
SEBACEOUS GLANDS :- Found near hair follicles in the ear canal. Secrete oil (sebum) that mixes with cerumen to keep the skin soft and waterproof.
