Your heart is an organ made mostly of cardiac muscle tissue 2. The Heart Your heart is an organ made mostly of cardiac muscle tissue The lub-dub, lub-dub noise of a beating heart is the sound of the valves opening and closing

Valves are located between the atrium and ventricle 2. The Heart 2 sides (left & right) Atrium (upper chamber) Ventricle (lower chamber) Valves are located between the atrium and ventricle The lub-dub, lub-dub noise of a beating heart is the sound of the valves opening and closing

How blood travels through your body 3. Blood Vessel Network How blood travels through your body 3 types of blood vessels

1. Arteries – carry blood away from the heart to the organs 3. Blood Vessel Network 1. Arteries – carry blood away from the heart to the organs 2. Veins – carry blood back to the heart 3. Capillaries – tiny, allows exchange between blood and cells in other tissue

Cardiovascular and The Respiratory System Your heart pumps blood to the lungs In the lungs, carbon dioxide leaves the blood and oxygen enters to blood From here, the blood travels back to the heart and distributes the oxygen- rich blood to the rest of the body 3D heart https://www.youtube.com/watch?v=oHMmtqKgs50

Blood Circulation – Due tomorrow! Color the flow of blood according to the image on Mrs. Stephens website. Label: Left and right ventricle Left and right atrium Veins (2) Arteries (2) Capillaries (3) 3. On the back of your diagram, describe what is happening at each step during circulation. There are a total of 5 steps If you are finished then you can read or work on other HW
