Across
  1. 3. return oxygen-depleted blood to the heart, starting small (venules) and getting larger closer to your heart. The two main are the superior vena cava and the inferior vena cava
  2. 5. results in blood shifting to the digestive system, fast or irregular heart rhythms, and can lead to heart failure or heart attacks.
  3. 6. circuit a circuit that carries deoxygenated blood between the heart into the lungs
  4. 9. circuit a circuit that provides the heart itself with oxygenated blood, then returns oxygen-poor blood to the heart’s atrium to send to the lungs
  5. 10. causes a rise in blood pressure and an increased heart rate due to the production of adrenaline
  6. 11. circuit a circuit that carries blood with oxygen, nutrients and hormones from the heart to the rest of the body and picks up waste products
  7. 13. arrest The heart stops beating during this event, as opposed to heart failure. a person loses consciousness and stops normal breathing.
  8. 15. of the circulatory system, symptoms might include strokes, heart failure, memory loss, organ damage, decreased blood flow, unconsciousness, and confusion.
  9. 16. a lack of oxygen supplied to the brain, causing trouble functioning and paralysis. a simple and easy blood pressure test to detect a high bp can help prevent this,
Down
  1. 1. an efficient system to transport blood to and back from all cells carrying nutrients, oxygen, and waste products from the cells, also known as the cardiovascular system, primary function is to transport nutrients and oxygen-rich blood to all parts of the body and carry deoxygenated blood back to the lungs
  2. 2. thin, muscular tubes that carry oxygenated blood away from the heart and to every part of your body. The largest of this is the aorta, and the smallest are coronary
  3. 4. pumps blood through closed vessels to every tissue within the body, pumps blood and follows the cardiac cycle in two phases, diastole and systole
  4. 7. delivers nutrients, oxygen and hormones to all cells in the body, without this the cells and tissues would not be able to function at their full capacity and would begin to malfunction
  5. 8. an abnormal or irregular heartbeat. most are harmless and don’t last long enough to impact function or require treatment.
  6. 12. connect very small arteries and veins and allow oxygen, carbon dioxide, nutrients and waste products in and out of cells through thin walls
  7. 14. vessel include your arteries, veins and capillaries, are are tubes that circulate blood
