c. What is the large, red-colored artery that exits from the top of the heart?

5. Select any of the purple-colored branching vessels inside the rib cage and use the arrow in the

content box to find and choose Pulmonary circulation from the hierarchy list. This will highlight the

circulatory route that takes deoxygenated blood to the lungs and returns oxygenated blood back

to the heart. The largest of these vessels, the _______________________________, immediately branches into

the right and left _______________________________ as it leaves the heart.

6. Make sure the pericardium is still hidden, and then select the aorta. Use the arrow in the content

box to find and choose Great vessels from the hierarchy list. How many great vessels are there and

what are their names? Hint: You may have to move the view around and observe it from all angles to

see all the great vessels.

7. By definition, _______________________________ carry blood away from the heart and

_______________________________ carry blood to the heart. Hint: Select any vein, use the up-arrow in the

content box to find and choose Veins from the list, and use the book icon to read the definition. Do the

same for arteries.

Superficial middle

cerebral vein

Superior anastomotic

vein (of Trolard)

Sigmoid sinus

Transverse sinus

Superior

4. Refresh the view and rotate it to observe the superior portion of the brain. What is the unpaired,

large vessel that drains blood from the brain?

a. Where is this chamber located?

b. Dural sinuses are channels between the layers of the dura mater that contain venous blood.

They are larger in diameter than regular veins and are often referred to as chambers.

5. Locate one of the superior anastomotic veins (of Trolard). Anastomoses are connected vessels

that form a network, providing alternate blood supply routes. These veins lie between which two lobes

of the brain?

6. Select any of the veins that parallel the superior anastomotic veins. This group of veins is called

________________________________. The regions of the brain that are drained by these veins are the

_______________________________.

middle cerebral vein and the _______________________________, which drain into the

_______________________________.

8. Posteriorly, the transverse sinuses and the superior sagittal sinus meet at the

_______________________________, which drains into the _______________________________, which in turn drains

into the _______________________________.

9. The sigmoid sinuses are located near the posterior lobes of the _______________________________.

10. Rotate the view to observe the anterior structures. Locate the large, paired cavernous sinuses.

They receive blood from the ophthalmic region. Blood from the cavernous sinuses travels through two

petrosal sinuses and the sigmoid sinus to drain into the _______________________________. In the system

tray on the left side of the screen, select and deselect the skeletal system icon to add and remove the

skeletal system structures from the view and observe where the internal jugular veins leave the skull

and enter the neck.

artery, which joins the posterior cerebral artery to the middle cerebral artery.

6. Rotate the view to observe the many collateral routes formed by the circle of Willis.

a. What prominent landmark of the nervous system is enclosed by the circle of Willis?

b. Which endocrine system landmark is enclosed by the circle of Willis?

7. Rotate the view to observe the superior surface of the brain. Branches from the circle of

Willis supply the entire brain. Two pairs of large arteries, the _______________________________ and

_______________________________ arteries, travel in the longitudinal fissure between the two hemispheres.

From these two pairs of arteries, several sets of arteries travel laterally across the brain to join the

middle _____________________________. Their branches supply the cerebrum.

B. Carotid and Jugular Vessels

In the Circulatory System Views section, select View 5. Carotid and Jugular. Use this view to

exits the skull through a space between the temporal and occipital bones called the

________________________________.

2. External to the skull, the posterior portion of the scalp is drained by the paired

_______________________________.

3. The sides of the scalp are drained by the _______________________________, which pass over the

temporal bones in front of the ears, and the _______________________________, which pass behind the ears.

These veins join to form the retromandibular vein.

4. The occipital veins and branches of the retromandibular vein join to travel down the outside of the

neck as the _______________________________.

one for each lung. Before it branches, this vessel is called the _______________________________, and its

branches are called _______________________________.

Superior vena cava

Heart valves

Pulmonary trunk

Left atrium

Pulmonary artery

Pulmonary vein

3. While viewing the posterior side of the heart, select the large surface of the lower heart to highlight

the sternocostal surface. Use the Hide button in the content box to hide this surface and rotate the

view to observe the opening to the pulmonary trunk.

a. Which heart chamber pumps blood into the pulmonary trunk?

b. Which valve controls backflow of blood from the pulmonary trunk into the heart?

4. Once inside the lungs, these arteries split into increasingly smaller branches that eventually reach

the pulmonary capillary beds, which wrap around the alveoli of the lungs. This is the site of

_______________________________.

5. The pulmonary arteries are unique because they are the only arteries that carry

_______________________________. Therefore, they are colored purple, not red, in the view.

6. Why are the pulmonary veins colored a dark shade of purple, instead of blue like the superior

vena cava, in this view?

7. Select the left lung and use the Hide button in the content box to hide it. If you want to hide the

trachea and bronchi as well, deselect the respiratory system icon in the system tray on the left side of

the screen to remove these structures from the view. Rotate the view to observe it from the back and

locate the four veins, two on each side, that return blood from the lungs to the heart.

the arteries that enter the inferior side of the liver. The common hepatic artery branch that supplies

the liver is the _______________________________. This artery terminates in left and right branches that

enter the liver, supplying it with freshly oxygenated blood.

3. Rotate the view to observe the veins that enter the liver from below. Locate the large vein that enters

the liver next to the proper hepatic artery branches. This vein is the _______________________________.

a. The hepatic portal vein delivers oxygen-depleted blood, which carries food absorbed by the

small intestine that will be processed by the liver before entering the heart. Which organs are

drained by this vein?

4. Portal veins are vessels that carry blood from one set of capillary beds—in this case, from the

digestive system—and deliver it to another set of capillary beds—in this case, to the liver—without

passing through the heart first. As the hepatic portal vein enters the liver, it branches into small,

permeable, capillary-like vessels called ________________________________. Products of digestion that are

absorbed by the intestines enter the liver through these permeable vessels. Other products, such as

materials reabsorbed from the colon and the products of red blood cell recycling from the spleen, also

enter the liver for processing.

5. Select the (VII) right posterolateral segment of the liver and use the Hide button in the content box

to hide it and observe the paired veins that drain the liver. These are the _______________________________,

which empty into the _______________________________.
