Excretion
In Humans metabolic system of the body produces substances such as
carbon dioxide garbage , ammonia , urea , uric acid , or even water . These substances trash if allowed to accumulate in the body will poison and harmful to the body . To avoid problems due to the trash substances , these substances must be removed from cells , tissues , and body . The process of spending the trash substances from cells , tissues , and body is called excretion . Expenditure process ( excretion ) is almost always involves a process
of osmoregulation , a process untukmemelihara osmotic pressure in humans
and animals in the face of the environmental condition of the body
parts that are used to perform osmoregulation in every kind of animal is
varied .
a. Simple Animals ( Animal porous / sponges ) body part is used to regulate the concentration of body fluids simply by the process of diffusion and osmosis directly through the cell membrane
b . Single-celled animals ( eg Amoeba , Paramaecium ) , body parts are used in osmoregulation
is the contractile vacuole via the mechanism of diffusion and osmosis .
c . Land animals , osmoregulation occurs through organ expenditure ( excretion ) , a kidney . In this case
kidneys act as organs of excretion and osmoregulation .
d . Aquatic invertebrates and vertebrates ( amphibians , fish , insects ) osmoregulation function through specific organs such as gills , skin , and even bowel .
Kidney , One system expenditure in humans is the urinary system . Human urinary system is composed of kidneys , ureters , bladder , and urethra ( see Figure 1.1 ) . Urinary system functions as follows :
Filter metabolic waste substances from the blood ; Structure Tool Excretion In Humans
Controlling blood volume , ie by removing the excess water produced by the cells of the body . Maintaining the amount of water in the blood is important to maintain blood pressure in order to move the gas , and solid waste substances spending remained normal .
Maintaining equilibrium concentration of certain salts . These salts must be present in certain concentrations for cell survival activities . The main organ of the urinary system is a pair of kidneys . This organ is red brown , shaped like a kidney bean seeds . The location of the kidney in the lumbar region , precisely at the back of the abdomen and protected ribs . The kidneys filter the blood that has been containing metabolic waste from the body's cells .
skin
Lungs
The lungs are organs including expenses incurred due to breathing air containing carbon dioxide and water resulting from the activities of the cell . The release of water could be seen when you breathe in cold air in the form of fog . Every day the body to release approximately 350 ml of water in the form of water vapor through the respiratory system . To prove the presence of water and carbon dioxide did
heart
Heart had a role in the system of spending because of liver cells to function as a place overhaul of red blood cells and decipher hameglobin resulting dyestuff bile ( bilirubin ) . The dye is released into bile in the urine and feces . The liver also plays a role in the formation of urea from ammonia , which is then excreted through the kidneys with urine .
