3 Explain in your own words what Circulatory System is. What role does oxygen and carbon dioxide play in the circulatory system? KeslerScience.com Describe the main organs and components of the circulatory system. KeslerScience.com

4 Assess It! Station Directions It is recommended that you have completed at least two of the following stations before working at this station. -Read It! -Explore It! -Watch It! -Research It! Each member will answer the questions from the task cards on the lab sheet in the Assess It! section.

5 A. Heart B. Veins Which is not a part of the circulatory system? Which describes the purpose of the circulatory system? A. To supply oxygen and nutrients to the body via blood vessels B. To remove digestive waste C. Arteries D. Brain C. To control all of the movement within the body D. To remove liquid waste as urine travel away from the heart and carry oxygen-rich blood to the body. A. Arteries B. Veins C. Bones D. Nerves

6 The circulatory system works directly with the system to exchange oxygen and carbon dioxide in the body. A. Excretory B. Endocrine C. Respiratory D. Nervous

7 Read It! Station Directions Each member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section. It is important to remember that the answers will come directly from the reading passage.

8 Heart Disease Heart disease includes numerous problems, many of which are related to a process called atherosclerosis. Atherosclerosis is a condition thatdevelops when a substance called plaquebuilds up in the walls of the arteries. This buildup narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can stop the blood flow. This can cause a heartattack or stroke. A heart attack occurs when the blood flow to a part of the heart is blocked by a blood clot. If this clot cuts off the blood flow completely, the part of the heart muscle supplied by thatarterybegins to die. Most people survive their first heart attack and returnto their normal lives to enjoy many more years of productive activity. But having a heart attack does meanyou have to make some changes. The doctor will advise you of medications and lifestyle changes according to how badlythe heart was damaged and what degree of heart disease caused theheartattack. Other types of Cardiovascular Disease: Heart failure: This doesn't mean thatthe heart stops beating. Heart failure, sometimes called congestive heart failure, means the heartisn't pumping blood as well as it should. The heartkeeps working, but the body's need for blood and oxygen isn't being met. Heart failure canget worse if it's not treated. If your loved one has heart failure, it's very importantto follow the doctor's orders. Arrhythmia: This is an abnormal rhythm of the heart. There are various types of arrhythmias. The heart canbeat too slow, too fast or irregularly. Bradycardia is when the heart rate is less than 60 beats per minute. Tachycardia is when the heart rate is more than 100 beats per minute. An arrhythmia can affecthow well the heartworks. The heart maynot be able to pump enough blood to meet the body's needs. Learnmore about arrhythmia. Heart valve problems: Whenheart valves don't openenough to allow the blood to flow through as it should, it's called stenosis. Whenthe heartvalves don't close properly and allow blood to leak through, it's called regurgitation. Whenthe valve leaflets bulge or prolapse back into theupper chamber, it s a condition called mitral valve prolapse. Whenthis happens, they may not close properly. This allows blood to flow backward through them. Discover more about the roles your heart valves play in healthy circulation.

9 What is the main cause of a heart attack? A. Blood flow is blocked by a blood clot B. Heart beats irregularly C. The valves in the heart don t operate properly D. cking a vessel to Based on how heart attacks are caused, which of the following is not a preventative measure? A. Someone that chooses not to smoke B. Regular physical activity C. A job that allows you to sit all day A blood clot is blo the brain D. Healthy diet If you heart is beating too fast at rest what is a potential problem you may have? A. Bradycardia B. Tachycardia C. Heart attack D. Stroke

10 What is the difference between stenosis and regurgitation? A. Stenosis is when valves don t open far enough and regurgitation is when heart valves don t close all the way. B. Regurgitation is when valves don t open far enough and stenosis is when heart valves don t close all the way.

11 Watch It! Station Directions Each member of the group will go to the website listed on task card #1 Complete the task cards in order. Every student will answer the questions from the task cards on the lab sheet in the Watch It! section of the lab sheet.

12 YouTube: G Drive: URL is case-sensitive 1. Click Play on the video. 2. Answer questions from cards #2-4 on your lab sheet. What is the difference between veins and arteries? YouTube What are the two things that happen as the blood passes through the lungs? Briefly summarize how blood flows through heart.

13 Research It! Station Directions Each member of the group will go to the website listed on task card #1 Complete the task cards in order. Every student will answer the questions from the task cards on the lab sheet in the Research It! section.

14 1. Go to Answer the following questions on your lab sheet. 1. Read the first paragraph and summarize the structure and function of the cardiovascular system 1. From the Blood Vessels section, describe the difference between arteries, veins, and capillaries. 2. How much blood is in the human body? 3. What are the 3 main functions of the cardiovascular system.

15 Explore It! Station Directions One member of the group will read the task cards in order. The group will be responsible for completing each of the tasks that are being read. Each member of the group will then write their conclusions down on the lab sheet in the Explore It! section.

16 Use diagram #1 for the following questions. 1. After looking at the diagram, what role do you think blood plays in the human body? 2. What organs and components make up the circulatory system? The circulatory system is responsible for transporting oxygen, nutrients, hormones, and cellular waste throughout the human body. Arteries carry blood away from the heart and veins carry blood to the heart. 1. Which vessels do you think contain the most oxygen and which carry the most carbon dioxide? Use diagram #2 for the following questions. 1. What is the main artery that carries blood to your brain? 2. What is the main vein that carries blood from your legs to the heart? 3. What is the main artery that carries blood to your lungs? The circulatory system is made up of your heart, arteries, veins, and capillaries. 1. List the 4 main components on your lab sheet.
