human excretory system of human waste is to remove the body. The system consists of a specific structure and a capillary network contributing to the removal process. human excretory system comprising the kidneys and functional units, the nephrons. secretory gland activity is modulated by a particular hormone, which regulates the amount of absorption in the nephron.
1). These are bean-shaped organs, which, on both sides of the spine at approximately the height of the stomach and liver blood enters the kidneys through the renal arteries and veins of the leaves by the kidneys. Tubes called ureters carry the waste from the kidneys to the bladder to be released for storage or.
renal urine products, an aqueous solution of waste products, salts, organic compounds and nitrogen compounds as two important uric acid and urea. uric acid results from the decomposition of nucleic acids and urea from the degradation of amino acids in the liver. produces both nitrogen can be toxic to the body and excreted in urine.
structural and functional unit of the kidney is nephron. Nephron producing urine and the main unit of homeostasis of the organism. This is essentially a long tubules with a series of related blood vessels. The upper edge of dilated tubules is called a capsule-shaped structure Bowman cutting. Under Bowman’s capsule, to form the proximal tubule coil then see a rotation of the loop of Henle is made. After the loop, tubular coil again as the distal tubule. then enters the duct collection, which also receives the most distal tubule urine.
Bowman’s capsule is a round ball of known glomerular capillaries. The blood occurs in the glomeruli of the renal artery. The force of blood pressure induced glomerular plasma pass through walls, beyond the walls of the Bowman’s capsule and flows in the proximal tubules. Red blood cells and large proteins remain in the blood.
After the plasma is proximal tubule, the roles in which the used material and the water can be recycled is passed. Salt, glucose, amino acids and other compounds, which are suitable for the flow again by active transport through the tubular cells in the blood. Osmosis and hormone activity helps this movement. blood fluid then flows through the loop of Henle in the distal tubules. hydrogen, ammonium, sodium, chloride and other ions in the body selected to maintain the delicate balance of salt figure: Again, salt, water and other materials useful in bloodstream.Homeostasis is again achieved by this process flow.
liquid moves from the distal tubule collecting ducts contain ingredients that are not needed by the body. This liquid is called urine. Urea, uric acid, salt and other metabolic waste products is an important component of urine. Urine flows through the ureters into the bladder fills bladder.When, the flow of urine through the urethra outward.
Figure 1 details the human excretory system. Position kidney structures (see above). A cross section of the kidney shows the two main parts (left). Details of nephrons, the functional units of the kidney (right).
Monitoring of renal function
nephron renal activity is controlled by the selection of a person and the environment and hormones. For example, if a person consumes large amounts of protein, much of urea in the blood of the protein digestion. Even on a hot day, your body will retain water for transpiration and cooling, so that the amount is reduced in urine.
People produce DHA (DHA) a hormone, also known asvasopressin called secreted by the posterior lobe of the pituitary. urine output is regulated by the rate of water absorption in the control nephron tubules.
Some people suffer from a condition in which very low levels of DHA are issued. The result is excessive urination and a disease called diabetes insipidus. Other shapes, which are not related to diabetes, diabetes mellitus, in general. People generally produce glucose transport molecules in the cells with the appropriate amounts insulin.Insulin disease. But when insulin is not available, glucose remains in the blood. Glucose from the bloodstream into the nephron, glucose concentrate, postage nephrons lot of water in the blood. And urine are abundant in the rule.
The adrenocortical hormones also control the content of urine. These hormones increase the reabsorption of sodium and chloride ions into the tubules. Therefore, affecting the balance of water in the body, because the water flows in the direction of the high content of sodium and chloride.
What is the function of the excretory system?
The main function of the excretory system
- First release of waste
- Remove unnecessary byproducts removed from the cell
- eliminating harmful chemicals
- Maintaining the stability of the equilibrium concentration of chemicals
What is the function of the lungs?
The lungs as -spons both institutions on either side of the chest. They consist of the alveoli. You are not responsible for the change of the oxygen in carbon dioxide, but to keep the life support level of the two gases in the blood by releasing additional carbon dioxide and maintaining a steady supply of oxygen. Every cell and all organisms may have a passive diffusion of oxygen into the bloodstream and use them in their own metabolism to produce carbon dioxide, which is released removed when passing through the cell circulation.
The role of the skin?
Leather is another part of the system, including welding, which helps to focus on the body itself in the regulation while maintaining cool. Salt helps the water to quickly evaporate the cooling of the skin. Sweat excreted through sweat. There are two types of sweat eccrine glands: apocrine sweat glands and sweat. The fundamental purpose of skin is to provide a waterproof protective covers the body’s internal environment is complex. The skin also plays an important role in supporting the circulatory and nervous system to maintain the attitude.
Exocrine function What?
Eccrine glands most of the water and salt and is used to control the body temperature. These glands are found throughout the body, but are most common around the soles, palms and forehead. They looked like a wound coil on the outside of the skin tube.
What liver function?
The liver is an important part of the system and shedding of human body. glycogen storage, plasma protein synthesis and drug withdrawal is regulated. Liver secretes bile, the base used to break down fat. Therefore, help get rid of waste that are not needed in the body. This toxic ammonia change, which is a toxic gas, filter urea, urea mentioned dangerous liquids.Kidneys (a mixture of sugar and debris) in a liquid urine sample. The liver is the largest gland of the body.
What is renal function?
Pass the liquid waste from the body by the kidneys. Located next to the spine in the back of the ribs, small kidneys (about 10 cm long) with a red-brown body bean. When the flow reaches the blood by the kidneys called to deposit unused and unwanted water, minerals and rich urea nitrogen molecule. residues kidneys filter blood, the formation of the so-called urine. Kidney channel urine to the bladder with two separate tubes called ureters. Muscle collects urine bladder contractions forcing urine out of the body through the urethra. Gland produces about 1.5 liters of urine per day. All that needs to be removed from the system. This is done by urination.
What role Gall?
Bile is a greenish or yellowish substance secreted by the liver that is used to decompose the fat, ethanol, and the acid residues. Consisting of water, cholesterol, lechithin, bicarbonate, bile salts and pigments. Bile is a solid base substance that is classified as basic. It is released through the bile ducts in the liver. Chemical digestion, which produces stored in the gallbladder and secreted into the small intestine, liver.
What is the function of the colon?
The large intestine or colon is the last part of the excretory system. It is the organ that is removed from the body of solid waste. Its mission is not only to eliminate solid waste and to collect wastewater can be reused. It is part of the digestive tract, which flows through the channel vertebrate. It is 7 meters in length and 6 process, transportation and disposal of solid waste.
