  1. 1. EXCRETORY SYSTEM GRADE 10 LIFE SCIENCES BY KAMATI VUYO 201203654 ALEJANDRA, C. ANDREW, P . BRONTE, S. CAMILA, M . KIM, P .
  2. 2.  The excretory system is a passive biological system that removes excess, unnecessary materials from an organism and prevent damage to the body  The matter, such as urine or sweat, that is so excreted  The act or process of discharging waste matter from the blood, tissues, or organs.
  3. 3. What the Excretory System does The system removes metabolic waste from the body. One of the main parts of the Excretory System is the kidney. The waste products arrive in the kidneys then the kidneys then start a process that removes hazardous toxins and products that the body can not use. The kidneys then mix the waste products together to form a liquid called urine. The urine then goes to the bladder and is kept there until it is released via the Uretha.
  4. 4. DIFFERENT ORGANS INVOLVED IN EXCRETORY SYSTEM: Kidney Urinary bladder Urethra urethral sphincter vena cava renal artery Ureter renal vein skin Dorsal aorta adrenal gland
  5. 5. Kidney The kidney is a reddish brown, bean shaped organ which is present in each of the sides of the Vertebral column .
  6. 6. Skin The skin is another part of the excretory system: it eliminates sweat, that helps cool the body and regulate the concentration of salt
  7. 7. Renal artery normally arise off the side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood.
  8. 8. Adrenal gland Are endocrine glands that sit at the top of the kidneys the right adrenal gland is triangular shaped, while the left adrenal gland is semi lunar shaped. They are chiefly responsible for releasing hormones in response to stress
  9. 9. Renal vein The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava. They carry the blood purified by the kidney.
  10. 10. Vena cava vein is the vena cava that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart.
  11. 11. urethral sphincter refers to one of two muscles used to control the exit of urine in the urinary bladder through the urethra.
  12. 12. Ureter Are muscular ducts that propel urine from the kidneys to the urinary bladder. In humans, the ureters arise from the renal pelvis on the medial aspect of each kidney before descending towards the bladder.
  13. 13. Urinary bladder The urinary bladder is the organ that collects urine excreted by the kidneys prior to disposal by urination. It is a hollow muscular , and sits on the pelvic floor
  14. 14. Dorsal aorta The dorsal aorta give branches to the yolk-sac, and are continued backward through the body-stalk as the umbilical arteries to the villi of the chorion.
  15. 15. Urethra In anatomy is a tube which connects the urinary bladder to the outside of the body.
  16. 16. Liver  Are produced as a result of break down of hemoglobin in the worn out red blood cells in the liver and excreted with the bile into the duodenum and removed along with the feces .
  17. 17. PROBLEMS  A problem that can happen in the Excretory system is Urinary tract infection- This is usually due to a bacteria which can cause burning during urination. It is usually treated with antibiotics.  Kidney stones- These are small hard deposits that develop in the kidneys. They can cause severe pain in the stomach and back. Surgery may be required if they are to expand.  Cystitis is an infection in the bladder, due to bacteria.  Blood in the urine- is a sign of a problem usually due to an urinary tract infection or kidney stones. Sometimes, it can be due to a more serious problem such as cancer.
  18. 18. HOW TO LOOK AFTER YOUR EXCRETORY SYSTEMS  Drink adequate amounts of water.  Exercise regularly.  Eat a nutritious diet consisting of fruits, vegetables, grains, and nuts.  Stay away from drugs, alcohol and tobacco
  19. 19. LARGE INTESTINE  The Large Intestine collects waste from throughout the body.  It extracts any remaining (usable) water and then removes waste.
  20. 20. Urethritis  Urethritis is an inflammation of the urethra caused by a bacterial or viral infection. Symptoms of urethritis vary between sexes. A symptom in men can be seen as blood in the urine or semen or even a discharge containing puss. In women, abdominal pain, pain during urination and fever may occur.
  21. 21.  How it Works with Other Systems Circulatory:  Blood that circulates through the body passes through one of the two kidneys. Urea, uric acid, and water are removed from the blood and most of the water is put back into the system  Endocrine:  Monitors levels of compounds and fluids  Kidney function must be constantly altered to provide the best internal environment for your cells  If too much water is present, hormones are released that allow for more urine production. If the body is dehydrated, less urine will be produced  Adrenal gland position on the top of each kidney. Adrenals release adrenaline into your body
  22. 22. WHICH IS THE RELATIONSHIP BETWEEN WATER AND EXCRETION?  Water is essential for digesting food. It is also important for getting rid of various toxic elements from the body, in the form of urine, sweat and faecal matter.  Water helps to cushion our joints and prevents shocks in them.  Water present in blood is the carrier of oxygen and nutrients to all our body cells.
