The human heart has four chambers: two ventricles, each of which is a muscular chamber that squeezes blood out of the heart and into the blood vessels, and two atria, each of which is a muscular chamber that drains and then squeezes blood into the ventricles. The two atria reside at the top of the heart; the two ventricles are at the bottom. And, the heart is divided into left and right halves, so there is a left atrium and left ventricle, as well as a right atrium and right ventricle.
<span>The reason that the heart is divided into halves is because of the two-circuit circulatory system. The right side of the heart can pump blood to the lungs, while the left side of the heart pumps blood to the rest of the body. Blood goes in both directions on each and every pump.</span>Human hearts, as well as the hearts and circulatory systems of some other mammals, are complex. They need to have a higher blood pressure to get the blood circulated throughout their entire bodies. Blood pressure is a force that sends the blood through the circulatory system.
Answer:
Tropomyosin

Answer:
The Boat-Over-Boat Technique should be performed when a capsized paddler is unable to re-enter their paddle craft without assistance. This open-water rescue technique requires a second kayak or canoe to be properly performed.
Explanation:
Step 1: The capsized paddler helps position your paddle craft so that it’s perpendicular to their capsized paddle craft (when in proper position, the two paddle craft should form a ‘T’ shape).
Step 2: Grasp the end of the capsized paddle craft that’s near you, while the capsized paddler pushes down on the other end of it to raise it upwards.
Step 3: Pull the capsized paddle craft on top of your own paddle craft to allow it to drain (when in proper position, this should form a '+' shape).
Step 4: Once drained and righted, you should slide the drained paddle craft back into the water.
Step 5: Hold the two paddle craft side by side to assist the capsized paddler while they re-enter their paddle craft.
Hope this is what you're asking and this helps there is also other maneuvers you can use when capsized.
