Function of Right Atrium

Back 5

Receives blood from the inferior and superior vena cavae and coronary sinus, then pumps to right ventricle

Front 6

Function of Right Ventricle

Back 6

Receives blood from the Right Atrium & pumps into the pulmonary trunk, whose branches carry to the lungs for oxygen

Front 7

Function of Left Atrium

Back 7

Receives oxygenated blood coming back to the heart from the lungs via the pulmonary veins then pumps it into the left ventricle

Front 8

Function of Left Ventricle

Back 8

Receives blood from the left atrium and pumps into the aorta to be carried to tissues in the sytemic circuit

and specialized fibers

Front 32

What is the middle layer of the heart called?
What is special about the intercalated discs that it contains?

Back 32

The mycardiums intercalated discs allow rapid transfer of electrical impulses

Front 33

Descending Aorta does what?

Back 33

The descending aorta is the part of the aorta beginning at the aortic arch & runs down through the chest and abdomen. It is divided into two portions, the thoracic and abdominal, in correspondence with the two cavities of the trunk. In the abdomen, the descending aorta branches into the two common iliac arteries which serve the legs.

Front 39

Blood flow to the liver is unique in that it receives both oxygenated & deoxygenated blood. As a result, the partial pressure of oxygen (pO2) and perfusion pressure of portal blood are lower than in other organs of the body.

Back 39

The portal venous system is responsible for directing blood from parts of the GI tract to the liver. Substances absorbed in the small intestine travel first to the liver for processing before continuing to the heart. Not all of the gastrointestinal tract is part of this system. The system extends from about the lower portion of the esophagus to the upper part of the anal canal. It also includes venous drainage from the spleen and pancreas.
