  5. Aneurysm: What can go wrong with your brain? • Bulging blood vessel that may rupture • Smoking increases your risk of aneurysms Alzheimer’s: • loss of neurons in brain  decrease in size of brain • loss of memory and cognitive function  confusion • Alcohol: • Can damage your cerebellum  balance problems • Tumors: • Abnormal growth of cells

  6. Aneurysm Bulging Artery

  7. Alzheimer’s 2 million people in the U.S. have Alzheimer’s

  12. Heart and Lung

  13. Functions of the Circulatory System • To carry oxygen from lungs to the rest of the body. • To carry digested food from the small intestine to all areas in the body which need it. • To aid in the disposal of all wastes from the body. • To distribute heat. • To fight diseases by using white blood cells to fight off infection.

  14. Components of the Circulatory System-Heart • Divided into 4 chambers • Right Atrium • Receives deoxygenated blood from body • Right Ventricle • Receives the blood from the rt. atrium and pumps it to lungs • Left Atrium • Receives oxygenated blood from lungs • Left Ventricle • Receives blood from lf. atrium and pumps it to the whole body

  15. Components of the Circulatory System-Vessels • Arteries • Carry blood away from the heart • Have thick muscular walls • Have a pulse • Deep under the skin • Have no valves • Veins • Carry blood to the heart. • Have thin walls • Do not have a pulse • Near surface of the skin • Have valves to stop back-flow of blood • Capillaries • Connect arteries and veins • Very thin walled—1 cell thick

  18. Circulation

  19. Each human has two lungs Between 10 and 12 inches long Lungs

  20. Functions of Lungs • Respiration • process of oxygen from incoming air entering the blood, and carbon dioxide, a waste gas from the metabolism of food leaving the blood

  21. Breath in air that is has oxygen (O2)—inspiration O2 travels down trachea, through the bronchi and bronchioles, into the alveoli for gas exchange Blood comes from heart and goes to the lungs to get oxygenated Exchange carbon dioxide (CO2) (from body) for new O2 by diffusion CO2 is breathed out—expiration Respiration

  22. Digestion

  23. Mouth & Esophagus • Food first enters the mouth and then moves down the esophagus in to the stomach. • The esophagus is made up of muscle and moves food downward by itself, without you controlling it. • Saliva helps to moisten food and break down carbohydrates.

  24. Stomach • It is a large muscular sack that receives chewed up food. • The stomach mixes the food you ate and begins to break down the proteins. • Once the food is mixed with stomach juices it is called chyme. • When mixed thoroughly, the chyme is squirted into the Small Intestine.

  25. Pancreas & Liver • Both organs make chemicals that break down carbohydrates, proteins, and fats in the chyme. • They squirt these chemicals into the first part of the Small Intestine called, the Duodenum.

  26. Small Intestine • This is where the broken down nutrients (carbs, fats, and proteins) are absorbed into the bloodstream. • The blood carries these nutrients to all parts of the body, where they are used for energy. • It takes 2-4 hours for the chyme to travel through the Small Intestine.

  27. Large Intestine • After the nutrients have been absorbed from the chyme, it moves into the large intestine. • Here water is absorbed from the chyme back into the body. • This is where the chyme becomes fecal material. • The fecal material is stored here until you are ready to defecate.

  28. Kidneys • Control how much water is in your body. • When you are dehydrated they keep more water in your blood. • When you drink a large amount of liquid, they let you get rid of the extra water in the form of Urine.
