Good Day! Sept. 3, 2024  But before we begin… Let’s check your attendance. Kindly get your books, notebooks, and pens. Sit properly. Stay focused.  Human Respiratory System Reminder: Performance Task As a doctor who is part of a medical mission, you are tasked to create an infographic that promotes the proper care of the respiratory and circulatory systems. The infographic should also promote awareness of the prevalent respiratory and circulatory diseases in the community. The content of the infographic must include the following topics:  Respiratory and circulatory diseases prevalent in the community  Preventive measures performed by the local health office  Treatment for the diseases Your infographic will be evaluated based on content, presentation, organization, and relevance.  Pulmonary vein Mitral valve aortic valve Left ventricle  Engage: Word Search!

Use the guide questions to evaluate the pie chart.  Diseases of the Circulatory System Explore: What’s in the Pie? 1. What trends or patterns do you observe in the pie graph? 2. How might the data in the graph influence public health policies or individual lifestyle choices?  Diseases of the Circulatory System Main Idea: “Disorders associated with the cardiovascular system are attributed to genetic defects, structural malfunctions, and lifestyle choices.”  Diseases of the Circulatory System Any injury to the blood or the network of blood vessels through which it flows can have serious consequences. The health conditions that can affect the circulatory system can be collectively categorized into diseases of the blood, the blood vessels, and the heart.  Diseases of the Circulatory System Diseases of the Blood Vessels: Atherosclerosis Atherosclerosis is the disease of the arteries that is associated with cholesterol buildup called plaque inside the walls of the arteries.  Diseases of the Circulatory System Diseases of the Blood Vessels: Atherosclerosis The blockage narrows the diameter of the arteries and impedes blood flow. The organs and tissues are thus deprived with oxygen and they may not function properly.  Diseases of the Circulatory System Diseases of the Blood Vessels: Atherosclerosis Causes: fat deposits from unhealthy diet, lack of exercise Prevention: Diet with low cholesterol, avoiding smoking, weight control and exercise. Treatment: medication, surgery, amputation  Diseases of the Circulatory System Diseases of the Blood Vessels: Stroke Stroke is a disorder that results from a blockage caused by the hardening of arteries in the back or in the neck vessels leading to the brain. A blood clot fixed within a blood vessel, called thrombus, can block the passage of blood.  Diseases of the Circulatory System Diseases of the Blood Vessels: Stroke A wandering clot, called embolus, can also stop blood flow. Stroke can also occur due to hemorrhage, where a diseased artery suddenly bursts.  Diseases of the Circulatory System Diseases of the Blood Vessels: Stroke Cerebral hemorrhage, occurs when a patient has atherosclerosis and high blood pressure.  Diseases of the Circulatory System Diseases of the Blood Vessels: Stroke Causes: embolus, thrombus, and hemorrhage Prevention: Healthy diet, exercise and regular check ups Treatment: medication, intensive rehabilitation  Diseases of the Circulatory System Diseases of the Heart: Coronary Heart Disease The inability of the blood to reach the coronary arteries of the heart can lead to coronary heart disease. The reduced blood flow on the blood vessels of the heart tissues causes a painful sensation in the chest, left arm, and shoulder.  Diseases of the Circulatory System Diseases of the Heart: Coronary Heart Disease The inability of the blood to reach the coronary arteries of the heart can lead to coronary heart disease. The reduced blood flow on the blood vessels of the heart tissues causes a painful sensation in the chest, left arm, and shoulder called angina pectoris.  Diseases of the Circulatory System Diseases of the Heart: Coronary Heart Disease Causes: aging, atherosclerosis Prevention: Balanced diet, smoking cessation, exercise Treatment: small doses of aspirin or other drugs  Diseases of the Circulatory System Diseases of the Heart: Hypertensive Heart Disease Hypertension or elevated heart pressure, results from the narrowing of the arterioles, the smallest arteries of the body. The narrowing of the blood vessels causes the increase in pressure, and the heart must pump harder to force blood flow.  Diseases of the Circulatory System Diseases of the Heart: Hypertensive Heart Disease Over time, the heart muscle may thicken and enlarge and become overworked. The overburdened circulatory system will then break down, possibly causing heart failure.  Diseases of the Circulatory System Diseases of the Heart: Hypertensive Heart Disease Causes: Atherosclerosis of the arterioles Prevention: Balanced diet, exercise Treatment: medication of antihypertensive drugs  Diseases of the Circulatory System Diseases of the Heart: Rheumatic Heart Disease This is a heart disease that usually occurs in children. It usually begins with an untreated bacterial infection caused by Streptococcus pyogenes. This bacterial toxin causes the body to trigger an immune reaction and the patient experiences rheumatic fever.  Diseases of the Circulatory System Diseases of the Heart: Rheumatic Heart Disease The bacteria causes damage to the heart, specifically the inflammation of the innermost layer of the heart called endocarditis.  Diseases of the Circulatory System Diseases of the Heart: Rheumatic Heart Disease Cause: infection from Streptococcus pyogenes Prevention: Immediate treatment of the bacterial infection Treatment: medication  Diseases of the Circulatory System Diseases of the Blood: Hemophilia In hemophilia, the blood does not clot properly, which leads to uncontrollable bleeding. This is a genetic disorder transmitted by the mother and the male offspring are mostly affected.  Diseases of the Circulatory System Diseases of the Blood: Hemophilia Causes: genetic disorder of the X chromosome Prevention: none Treatment: medication of antihemophilic factor, blood transfusion  Diseases of the Circulatory System Diseases of the Blood: Anemia Anemia is a condition wherein the red blood cell count stays persistently low. The normal count is 4.7 to 6.1 million, and the deficiency may lead to low hemoglobin.  Diseases of the Circulatory System Diseases of the Blood: Anemia Low hemoglobin leads to insufficient supply of oxygen in the cells and tissues of the body. Anemia can also be caused the production of sickle cells (abnormal red blood cells) that do not function well.  Diseases of the Circulatory System Diseases of the Blood: Anemia Causes: nutritional deficiency, hereditary Prevention: Balance diet Treatment: Iron supplements  Diseases of the Circulatory System Diseases of the Blood: Leukemia Leukemia is a disorder characterized by an abnormal increase in the number of white blood cells. Leukemia is considered as the most dangerous blood disorder.  Diseases of the Circulatory System Diseases of the Blood: Leukemia Because white blood cells are larger, it occupies spaces for RBCs and platelets.  Diseases of the Circulatory System Diseases of the Blood: Leukemia Cause: Hereditary Prevention: none Treatment: radiation and drugs Diseases of the Circulatory System Elaborate: In a piece of paper, create a slogan/ poster on how to promote a healthy Circulatory System. Diseases of the Circulatory System Elaborate: Guide Questions: 1. What message do you want your slogan or poster to convey to others about circulatory health? 2. How did the information you learned today influence the design and content of your poster/slogan? "Pharynx (also "Pharynx" The pharynx is known as voice box)" and the throat, and "Larynx the larynx is The pharynx is correctly actually the (voice identified as throat box)" the voice box. Question: How does exercise help improve our well-being? Evidence Number 1: Exercise strengthens the lungs and heart, making your body more efficient at getting oxygen into the bloodstream and transporting it to working muscles. This efficiency reduces the likelihood of becoming short of breath during exercise over time. Evidence Number 2: Regular exercise reduces the risk of serious illnesses such as heart disease, stroke, diabetes, and some forms of cancer, including lung cancer. Additionally, exercise can improve mental health by reducing anxiety and depression, enhancing attention and memory, and lowering the risk of dementia, including Alzheimer's disease.  Diseases of the Circulatory System Evaluate: 1/4 sheet of paper 1.
