What type of secretion is sweat?
What type of secretion is sweat?
Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct.
What type of secretion is sweat and saliva?
Salivary glands and sweat glands are examples of exocrine glands. Both saliva, secreted by the salivary glands, and sweat, secreted by the sweat glands, act on…
What produces moisture called perspiration?
Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. The eccrine sweat glands are distributed over much of the body and are responsible for secreting the watery, brackish sweat most often triggered by excessive body temperature.
Is sweat hypotonic or hypertonic?
Sweat is hypotonic to plasma and to some of the electrolyte replacement drinks available.
Can you drink hypotonic water?
However, while isotonic drinks are often used to combat dehydration during exercise, hypotonic drinks could be a better solution and are recommended for those looking to replace fluids lost to sweat quickly. Hypotonic drinks cause blood cells to swell as they absorb fluid faster than they lose it.
How much salt do you lose when sweating?
Sweat typically contains 40-60 mmol/L of sodium, leading to approximately 20-90 mmol of sodium lost in one exercise session with sweat rates of 0.5-1.5 L/h.
Which is the correct definition of the word perspiration?
Perspiration Definition. Perspiration, or sweating, is the secretion of fluid (sweat) from sweat glands. This word is both a noun and a verb; it can refer to the act of sweating or to the sweat itself. Sweat mostly consists of water, along with minerals, urea, and lactic acid.
Where does perspiration take place in the body?
Perspiration. The apocrine sweat glands, associated with the presence of hair in human beings (as on the scalp, the armpit, and the genital region), continuously secrete a concentrated fatty sweat into the gland tube. Emotional stress stimulates contraction of the gland, expelling its contents.
What is the role of perspiration in excretion?
However, perspiration also plays a role in excretion of toxins and waste products. Sweat is chemically similar to the plasma, but certain components are selectively retained or excreted.
What is the function of perspiration in dogs?
In other mammals with fewer sweat glands, perspiration does play a role in thermoregulation, but it is not as major. For example, dogs have some sweat glands on the pads of their feet to help keep them cool, but they mainly regulate their temperature by panting.

What kind of secretion does the eccrine sweat gland produce?
The clear secretion produced by eccrine sweat glands is termed sweat or sensible perspiration. Sweat is mostly water, but it does contain some electrolytes, since it is derived from blood plasma. The presence of sodium chloride gives sweat a salty taste.
