COT 1 in science 9

1. Diseases of Respiratory and Circulatory System

2. 01 02 03 04 Explain the inner workings of the respiratory system and circulatory system and relate the role of circulatory system to the respiratory system. Objectives At the end of the period the students should be able to: Explain the negative effect of cigarette smoking on the circulatory and respiratory system. Identify ways of detecting and preventing diseases in the respiratory and circulatory system. Infer how one’s lifestyle can affect the functioning of the respiratory and circulatory systems.

3. FILL ME OUT! Refer to the diagrams, and check your understanding to the respiratory and circulatory system by labelling each part and giving its function in the box corresponding to the part.

4. YOU COMPLETE ME! Study and complete the diagram of blood circulation in the heart. Answer guide questions after completing the diagram.

5. GUIDE QUESTIONS: How do the heart and the lungs work together? 1 2 Why is oxygen important to your body? 3 Describe the sequence of oxygen, carbon dioxide and blood flow in your own words.

6. Mercury is the closest planet to the Sun and the smallest one in the Solar System—it’s only a bit larger than the Moon Problem and solution Venus has a beautiful name and is the second planet from the Sun. It’s a hot place and has a poisonous atmosphere Problems Solutions Answer this guide question while you are watching—What are the effects of smoking in the systems of the body?

7. LET’S SHARE!

8. PREVENTION IS BETTER THAN CURE!

9. With your group mates, create a story that illustrates various ways of preventing diseases that affect the respiratory and circulatory systems. Y ou must also show the importance of keeping our bodies healthy and free from illnesses. P resent the story that you made in front of the class by means of role-playing. C onsider the following criteria to serve as your guide in completing the given task. Procedure

10. LET,S DISCUSS!

11. Smoking a Cigarette Raised blood pressure and heart rate Constriction (tightening) of blood vessels in the skin, resulting in a drop in skin temperature Less oxygen carried by the blood

12. Smoking a Cigarette Stickier blood, which is more prone to clotting Damage to the lining of the arteries, which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls)

13. Smoking a Cigarette Reduced blood flow to extremities like fingers and toes Increased risk of stroke and heart attack due to blockages of the blood supply.

14. Diseases in the Circulatory System Coronary Heart Disease Coronary Heart Disease is mainly caused by smoking. Cigarettes form plaques that form in the arteries, which can lead to atherosclerosis, which is also known as hardening of the arteries.

15. Diseases in the Circulatory System Coronary Heart Disease chest pain shortness of breath nausea weakness or dizziness Symptoms:

16. Diseases in the Circulatory System Stroke Toxins in the blood from smoking cigarettes contribute to the development of atherosclerosis.

17. Diseases in the Circulatory System Stroke Atherosclerosis is a progressive hardening of the arteries caused by the deposit of fatty plaques and the scarring and thickening of the artery wall.

18. Diseases in the Circulatory System Stroke trouble with walking, speaking, or seeing headache paralysis or numbness on one side of body Symptoms:

19. Diseases in the Circulatory System Peripheral Vascular Disease This is similar to almost any other disease from the circulatory system. In PAD, fatty deposits build up in the inner linings of the artery walls. These blockages restrict blood circulation, mainly in arteries leading to the kidneys, stomach, arms, legs, and feet.

20. Diseases in the Circulatory System Peripheral Vascular Disease In its early stages a common symptom is cramping or fatigue in the legs and buttocks during activity. Such cramping subsides when the person stands still. This is called "intermittent claudication”.

21. Diseases in the Circulatory System Abdominal Aortic Aneurysm This disease happens when large blood vessel that supplies blood to the abdomen, pelvis, and legs becomes abnormally large or balloons outward. It happens slowly over a period of years.

22. Diseases in the Circulatory System Abdominal mass Abdominal rigidity Anxiety Clammy skin Nausea and vomiting Symptoms: Abdominal Aortic Aneurysm

23. Diseases in the Circulatory System Pain in the abdomen or back -- severe, sudden, persistent, or constant. Pulsating sensation in the abdomen Symptoms: Abdominal Aortic Aneurysm

24. RESPIRATORY SYSTEM

25. Diseases in the Respiratory System Emphysema This is a chronic lung disease. The affects are in the air sacs in the lungs (alveoli). There is no cure for this disease, but treatments include inhalers, or inhaled steroids. Sometimes, surgery is a necessity.

26. Diseases in the Respiratory System Emphysema Fatigue Shortness of Breath Coughing Weight Loss Depression -Heart Problems SYMPTOMS

27. Diseases in the Respiratory System Lung Cancer This disease is an abnormal, continual multiplying of cells that has possible results of lumps, masses, or tumors beginning in the lining of the bronchi (large airways), and possibly other areas of the respiratory system.

28. Diseases in the Respiratory System Lung Cancer SYMPTOMS constant chest pain shortness of breath wheezing recurring lung infections bloody or rust-colored sputum

29. Diseases in the Respiratory System Lung Cancer SYMPTOMS hoarseness swelling of the neck and face pain and weakness in the shoulder arm, or hand -unexplained fever.

30. Diseases in the Respiratory System Chronic Bronchitis This is a long-term inflammation of the bronchi (large airways), while symptoms include coughing for long periods of time.

31. Diseases in the Respiratory System Chronic Bronchitis SYMPTOMS coughing for long periods of time (may include mucus) low fever tiredness

40. 1. What are the negative effects of smoking cigarette? 2. How can we help people to avoid vices? 3. What is the process of the oxygen flow in the bloodstream? 4. Does the respiratory and circulatory have a relation? In sight 1 example. 5. Enumerate the major parts of respiratory system. Circulatory system. ASSESSMENT
