When you cry, don't you excrete salt water? when you run and sweat, you excrete salt water. When you drink water and later pee, you excrete urea.
yes ...swet is excretion of water and salts from our body
The skin is considered an organ of excretion because it sweats, getting rid of toxins and certain mineral salts.
· Skin o Expels water, sodium chloride and urea during sweating. (Incidental loss: because sweating is a response to a rise in temperature and not to a change in blood compostion.)
The skin,is the organ that uses sweat to excrete water,salts,and a small amount of urea
skin
excretion means is the removal of wastes in the body
anus,eyes,ears,nose and genital. These excreted chhit/ feces,tears,dirt,nosy water etc. Skin also sweat.
Fresh water fish differ physiologically from salt water fish in several respects. Their gills must be able to diffuse dissolved gasses while keeping the salts in the body fluids inside. Their scales reduce water diffusion through the skin: freshwater fish that have lost too many scales will die. They also have well developed kidneys to reclaim salts from body fluids before excretion.
The kidney is the main organ, that is responsible for the excretion of waste products. Other organs of excretion are your liver, lungs and skin.
they leave through sweat
The skin produces sweat, but this is not really an excretion. The main function of sweat is to help cool the body. However sweat also contains small amounts of urea, the main waste found in the urine. The concentration of urea in sweat is much less than that in the urine, so this is not a significant route for excretion. Sweat also contains samll amounts of salts (minerals), but again the urine is the main route for the elimination of excess salt.

excretion done by the kidneys are mainly for nitrogenous wastes whereas only sweat is being excreted through the skin...the term 'excretion' is actually used only for removal of nitrogenous wastes...
