DESCRIPTION
Weird body facts Hiccups occur when a spasm contracts the diaphragm, causing an intake of breath that is suddenly stopped by the closure of the vocal cords (glottis). Increasing the level of carbon dioxide in the blood usually stops hiccups. Learning goal. - PowerPoint PPT Presentation

Weird body factsHiccups occur when a spasm contracts the diaphragm, causing an intake of breath that is suddenly stopped by the closure of the vocal cords (glottis).Increasing the level of carbon dioxide in the blood usually stops hiccups.
Learning goal
• To describe the role of the liver and the kidney in excreting waste.
You will show your understanding by:• Outlining the parts of the kidney and
describing what happens in each part
The Importance of Excreting Wastes
• The Liver– Metabolizes toxins (alcohol) so kidney can
excrete them– Processes harmful products from protein
metabolism for kidneys to excrete as urea• Recall general amino acid structure
The KidneyStructure & Function
What is the main function of the kidney?
• The average body contains about 42 L of water. In one day, the kidneys filter 180 L of water and only 1.5 - 2 L appear in the urine.
• The kidney plays a vital role in– Extracellular fluid (ECF) regulation (remove
wastes like ammonia -> urea)– Acid-base balance– ECF osmolality ([ion] in fluid) and volume– Hormone production -> Vitamin D and
Erythropoietin (RBC production)
Location and structure of the kidney
Another interesting fact
• The human body makes anywhere from 1 to 3 pints of saliva every 24 hours.

Kidney Structure & Function
• The kidneys have three basic mechanisms for separating the various components of the blood: – filtration, reabsorption, and secretion.
• The structure of the kidney is such that it allows for this function
• Interactive video
Structure and Function of the Nephronpp. 346 - 356
• Your task:– Your group will be responsible for one area of the
nephron– You will need to illustrate its structure and outline
its function. Explain its function in all aspects of renal physiology: water and electrolyte balance, hormone production, pH balance, etc.
