The small intestines and the first 2/3 of the large intestine are supplied

with blood by what artery?

The Superior Mesenteric Artery

The Superior Mesenteric artery branches into what arteries?

The mesenteric arteries.

Name the first branch off the aorta below the diaphragm

The celiac artery

The celiac artery branches into what three arteries?

The gastric, splenic, and hepatic arteries.

What organs do these arteries supply blood to?

The gastric supplies blood to the stomach, the splenic supplies blood

to the spleen, and the hepatic supplies blood to the liver.

Are there celiac, inferior, and superior mesenteric veins that empty

directly into the vena cava?

No. The celiac, inferior, and superior mesenteric veins empty into the Hepatic Portal System.

What is this thin shiny watery mesh-like

membrane?

Mesentery

Name this red blood vessel.

Mesenteric artery

Name this yellow stained blood vessel.

Mesenteric vein.

What does the Hepatic Portal System empty into?

The liver

The large yellow vein that the mesenteric veins empty into is

called?

The Hepatic Portal Vein

What are the special macrophages in the liver that

phagocytize debris and bacteria and also cleanse the blood?

Kupffer cells which prowl the walls of the liver sinusoids.

What artery takes blood the the last 1/3 of the Large intestine?

The inferior mesenteric artery.

Products of digestion that are filtered through the Hepatic Portal System are

said to be?

Blood-borne

What products of digestion are Blood-borne?

Amino acids, monosaccharides, disaccharides, etc.

In the small intestine, name the finger-like projections that

increase the surface area for absorption of nutrients.

Villi (singular villus)

Each villus contains a capillary bed and what other structure?

A lacteal, a dead-end beginning of a lymphatic

vessel.

What is the function of the lacteal within the villus?

Lacteals absorb excess interstitial fluid and are responsible for

picking up and transporting the products of fat digestion.

What are the products of fat digestion?

Monoglycerides, diglycerides, glycerol, cholesterol, etc.

What structure do the products of fat digestion originally become?

Chylomicrons--packages of fatty things surrounded by a transport

protein

Chylomicrons are made by the brush border cells and exported to what

dead-end vessels?

Lacteals. What larger and larger vessels do lacteals empty into?

Lymphatic vessels

The lymphatic fluid in these vessels passes through what

structures?

Lymph nodes

What is the name of the large sinus that the lymphatic vessels

eventually empty into?

The cisterna chylii

The ciserna chylii is the beginning of what main duct in the lymphatic

system?

The thoracic duct

The thoracic duct empties into what vessel?

The left subclavian vein

From the left subclavian vein, trace the path of the blood en

route to the heart

The left subclavian vein empties into the left brachiocephalic vein, which empties into the superior vena cava, which empties into the right heart.

What organ filters the lymph-borne products of fat digestion?

None. Products of fat digestion go straight into the bloodstream.

How do we refer to the products of fat digestion?

As lymph-borne
