HEY HERE IS YOUR ANSWER
The main excretory organs of human are as follows –
(i) Kidneys: kidneys are most vital and prominent organ in excretory system. Excretory process is mostly done by kidneys.
In the human being, there exists a pair of the kidney which is dark-red, bean-shaped.Its weight is 140 grams.There are two parts of it. The outer part is called cortex and the inner part is called medulla.A kidney has about ten lakh structural and functional units, called as nephrons.Bowman's capsule is a cup-like structure in every nephron called.Glomerulus of thin blood vessels is found in the Bowman's capsule which is made up of two types of arterioles.
(a) Afferent arteriole: An afferent arteriole connects the renal artery to the glomerular capillary network in kidney's nephron, Which carries the blood to the glomerulus, starting the filtering process.
(b) Efferent arteriole: it has less diameter than afferent arteriole and takes blood out of the glomerulus.
Functions of kidney:
It maintains PH of blood.Ultra filtration – it is the process of filtration of liquids into the cavity of Bowman's capsule.It maintains salt contents of the body.It eliminates toxic substances of the body.Homeostasis – kidney removes various unwanted materials from the blood, it helps in keeping the internal environment of the body constant.Kidney secrets an enzyme Renin which change the plasma protein, the angiotensinogen.
(ii) Skin: Oil gland and sweat glands secrete sebum and sweat respectively. Along with sebum and sweat some other excretory substance to enhance the excretory process.
(iii) Liver: the cells of the liver transform the excessive amino acids and ammonia of the blood into urea which is the main excretory substance. And spleen split the damaged blood cells and separate them from the blood flow.
(iv) Lungs: in general Lungs are associated with the respiratory system but it also plays an important role in the excretory system. Lungs do the excretion of the gaseous substance. CO2 and water vapours and some substances like garlic, onion and some species are also excreted by lungs.
