Describe the function of the kidneys in the excretory process

coaster_crazzy

Best  Each of these organs moves METABOLIC wastes out of the blood stream.  

Lungs move CO2 out of the blood  

Skin excretes uric acids out in sweat  

Kidneys filter uric acids out into urine, along with excess water and other compounds  

Liver also filters metabolic wastes from the bloodstream.

In my research the kidneys act like a filter, filtering out the sugars from sodas, tea, and in some cases coffee. Hope this helps!

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
