Question

How do skin and lungs help in excretion​

Answer 1

Explanation:

The skin is part of the integumentary system, but it also plays a role in excretion through the production of sweat by sweat glands in the dermis. Although the main role of sweat production is to cool the body and maintain temperature homeostasis, sweating also eliminates excess water and salts, as well as a small amount of urea. When sweating is copious, as in the figure below, ingestion of salts and water may be helpful to maintain homeostasis in the body.

Answer 2

Answer:

The skin plays a role in excretion through the production of sweat by sweat glands. ... The lungs are responsible for the excretion of gaseous wastes, primarily carbon dioxide from cellular respiration in cells throughout the body. Exhaled air also contains water vapor and trace levels of some other waste gases.
