- Order the contraction of the heart involving the nodes starting with blood entering the right atrium and left atrium. Sinoatrial node signals contraction to surrounding tissues Left atrium contracts and Atrioventricular node is triggered Ventricles contract sending blood to the lungs and body Blood enters the right and left atrium (start) Punkinje fibers transports a signal to the Right and Left Ventriclesmake sure you do not use the internet. Be specific with your answers, this means that I am expecting you to add in some structures and functions involved. Each question should be approximately 4 sentences long. 1. Describe how the circulatory system and the respiratory systems work together.Watch the linked videos then answer the questions below. https://youtu.be/CWFyxn0qDEU https://youtu.be/X9ZZ6tcxArI 1. How much does the average human heart weigh? 2. Which chamber is considered low pressure? 3. What causes the "Lub Dub" sound of our heartbeat?
- PLEASE use in your own words and NOT outside sources just provide the answer itself in brief sentences THANK YOU! 1. When you stand up, gravity causes blood to pool in your legs and abdomen. This decreases arterial blood pressure because there's less blood circulating back to your heart, leading to a condition called orthostatic hypotension. Describe the baroreceptor reflexes in response to this drop in blood pressure. Be as specific as possible.The figure above represents the action potential of pacemaker cells. The horizontal line indicates 1. What value is the horizontal line equivalent to for pacemaker cells? Question Blank 2 of 8 How about for contractile cells? 2. Letter A covers the red line starting below the horizontal line, which event does this signify? 3. Which letter/s cover/s the action potential of pacemaker cells? 4. Which letter represents the opening of K+ channels causing a fast efflux of this ion to the cell membrane? 5. Which letter represents the closing of Ca+ channels? 6. How about the funny channels?A Moving to another question will save this response. Question 14 From which chamber of the heart does blood leave to the lungs?
