What carries blood away from the heart? (A) Arteries (B) Veins (C) Both A & B (D) None The Heart The heart consists of many layers including a muscular layer that allows the heart to contract. These contractions enable blood to move throughout the circulatory system...
Oxygen-poor blood returns from the body to the heart through thesuperior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart. Which side of h...
which pump blood to the lungs and body. The twoventricles are thick-walled chambers that forcefully pump blood out of the heart to either the lungs or the body.. Differences in thickness of the heart chamber walls are due to variations in the amount of myocardium present, which reflects the...
The high-pressure chamber receives air directly from the cylinder, while the intermediate-pressure chamber is in contact with the ambient water pressure through the diaphragm or piston. The system operates like this: You inhale, thereby lowering the pressure in the intermediate-pressure chamber to ...
There was nothing to wash out -- no stain of any kind -- no blood-spot whatever. I had been too wary for that.When I had made an end of these labours, it was four o'clock-- still dark as midnight. As the bell sounded the hour, there came a knocking at the street door. I ...

It wasn't that long ago that little research had been done on how travel impacts horses. Most advice came from the shared experiences of other horse owners and commercial transporters. That’s why research findings from the University of California, Davi
, also called the cardiac electrical system, helps the heart contract, thus pumping blood through the body. It is made up of several different parts, including a sinoatrial (sinus) node. The sinus node is a small collection of tissue. It can be found in the heart's upper right chamber....
