  1. OCR Level 3Cambridge Technicalsin Health and Social Care Introduction to Unit 5: Anatomy and physiology for health and social care

  2. Meet Mike Mike likes to eat takeaways. He drinks 2 pints of alcohol each evening. He smokes 20 cigarettes a day.

  3. What’s happening to Mike’s body?

  4. How the heart functions if a person is healthy On the right side, the upper chamber fills with oxygen-depleted blood from your body and pushes it via the lower chamber and the pulmonary artery back to the lungs. Here blood picks up oxygen and releases carbon dioxide.

  5. How the heart functions if a person is healthy On the left side, the upper chamber fills with oxygen-rich blood from the lungs. This is pumped via the lower chamber into the aorta and out to the body to provide cells with the crucial oxygen they need.

  6. How the heart functions if a person is healthy On average, most people have a heart rate of around 72 beats per minute at rest.

  7. The impact of Mike’s lifestyle on his heart

  8. The impact of Mike’s lifestyle on his heart Mike’s high fat diet may result in his coronary artery becoming furred up or partially blocked with fatty material called atheroma.

  9. The impact of Mike’s lifestyle on his heart This may result in the artery not supplying enough blood to the heart muscle to meet its needs during exertion or activity.

  10. The impact of Mike’s lifestyle on his heart This could result in muscle ‘cramps’, causing chest pain known as angina.

  11. The impact of Mike’s lifestyle on his heart If Mike continues to have an unhealthy lifestyle this may result in the coronary artery becoming completely blocked with no blood reaching the heart muscle, causing a heart attack.

  12. What’s happening to Mike’s body?

  13. How the lungs function if a person is healthy Your lungs will take gas that your body needs to get rid of (carbon dioxide) and through a process of gaseous exchange, exchange it for gas that your body can use (oxygen). A person may breathe in and out anywhere from 15-25 times per minute.

  14. The impact of Mike’s lifestyle on his lungs Over time, the constant irritation of tar-producing smoke in the lungs can lead to a breathing disease known as emphysema, which causes shortness of breath. Smoking is related to a high number of lung cancer related deaths in the UK. Cigarette smoking coats the lungs with a toxic known as tar.

  15. What’s happening to Mike’s body?

  16. How the kidneys function if a person is healthy Your kidneys act as a filter. They retain fluids and nutrients that your body needs and gets rid of those fluids and nutrients that your body no longer needs by making urine.

  17. How the kidneys function if a person is healthy Your kidneys will: Remove wastes from your body (urea, ammonia, drugs, toxic substances).  Keep the acid/base concentration of your blood constant. Regulate the composition of your blood: Keep the volume of water in your body constant.

  18. The impact of Mike’s lifestyle on his kidneys When the lungs absorb the carcinogens in tobacco smoke into the bloodstream, these chemicals become concentrated in the kidneys as they try to filter the blood. This impacts on the function of the kidneys and can lead to kidney failure. Smokers have an increased risk of kidney disease and cancer, according to the National Kidney and Urologic Diseases Information Clearinghouse (NKUDIC).

  19. How could Mike improve his lifestyle in order to reduce the negative impacts of his lifestyle on his organs?

  20. Stop smoking. Reduce alcohol intake. Exercise frequently. Increase water intake.

  21. What will you learn? Understand how homeostatic mechanisms operate in the maintenance of an internal environment. Be able to interpret data obtained from monitoring routine activities with reference to the functioning of healthy body systems. Organisation of the Human Body. Understand the functioning of the body systems associated with energy metabolism.
