After turning in the Quiz: Label the shapes and draw arrows to show the direction of blood flow. *Add in the four chamber of the heart and the major vessels (aorta, vena cava, pulmonary artery, pulmonary vein) Heart Body Lungs

Heart Right Atrium Left Atrium Body Lungs Right Ventricle Left Pulm. vein Vena Cava Right Atrium Left Atrium Body Lungs Right Ventricle Left Ventricle Aorta Pulm. artery

Write a paragraph describing the pathway of blood through the body. In your description be sure to use the following terms AND UNDERLINE THEM: Right atrium Body Right ventricle Lungs Left atrium Pulmonary Artery Left ventricle Pulmonary Vein Aorta Oxygen Poor Blood Vena Cava Oxygen Rich Blood

The Pathway of Blood First the oxygen poor blood moves into the right atrium through the vena cava. Next, the oxygen poor blood moves into the right ventricle. The blood then leaves the heart though the pulmonary artery and goes to the lungs to pick up oxygen. The oxygen rich blood then comes back to the heart through the pulmonary veins and flows into the left atrium. The blood next moves to the left ventricle and then goes out to the body cells through the aorta. The oxygen rich blood delivers oxygen and nutrients to all of the cells. After, the oxygen poor blood will flow back to the heart through veins, back to the Vena Cava and the process begins again.

Current Events!

Hypertension Description: consistent high blood pressure Causes: age, birth control pills, medicines, pregnancy, kidney failure, thyroid disease etc. Symptoms: None (“silent killer”) Treatment: 1.Lifestyle changes: change diet, no smoking, less/no stress 2.

Most common type of A-Fib. Involves a very fast/irregular contraction of atria. Normal Heart Rhythm Arrhythmia

Stroke Description: A stroke occurs if the flow of oxygen-rich blood to a portion of the brain is blocked. What causes an Ischemic Stroke?: Artery that supplies oxygen-rich blood to the brain becomes blocked. *Most common type What causes Hemorrhagic stroke? Artery in the brain leaks blood or bursts open Symptoms: numb on one side 3) confusion slurred speech 4) sudden weakness 5) Severe Headache Treatment: Get to a hospital immediately! medicines – blood thinners, surgery – to open blockage
