what vessel serves as the source of the spleen’s blood supply from the aorta?

The aorta is the conduit that supplies blood to the spleen, and it is known as the source vessel. The splenic artery is a branch of the celiac truck that runs through the abdomen.

Where do blood vessels enter the spleen?

Lymphatic cells such as lymphocytes and macrophages form cords in the red pulp, which is composed of venous sinuses filled with blood and lymphatic cell cords. After entering the spleen through the splenic artery, the blood travels into the sinuses, where it is filtered, and finally exits through the vein of spleen, known as the splenic vein.

Which part of the spleen is its primary site of immune function?

The white pulp (WP) of the spleen is the principal immunologic zone in both humans and animals; nevertheless, the WP accounts for less than a quarter of total splenic tissue in both species. The red pulp (RP) constitutes the bulk of the tissue and is distinguished from the white pulp (WP) in that it has an immunological role different from the WP.

Does spleen have afferent vessels?

Because the spleen lacks afferent lymphatic arteries, as do lymph nodes, it can only absorb white blood cells from the bloodstream, rather than from lymph nodes. Lymphatic capillaries and efferent veins connect the spleen to lymph nodes located outside of it.

Which part of the spleen is its primary site of immune function quizlet?

Which component of the spleen is responsible for the majority of its immunological function? The spleen’s white pulp is composed of reticular fibers that contain lymphocytes suspended in suspension. These lymphocytes are responsible for the cleansing of the blood and are a crucial component of immunologic monitoring and response.

What region is the spleen in?

In the upper left part of your abdomen, directly below your stomach and behind your diaphragm, you will find your spleen. Designed in the shape of a very small smooth, spherical catcher’s glove with notches on the upper front edge, it is soft and purple in color and feels good in the hand.

Is the spleen above or below the diaphragm?

Overview. The spleen is a kidney-shaped organ that is found in the left hypochondrium and partially in the epigastrium, and it is located between the 9th and 11th ribs. It is shaped like a shoe and rests between the 9th and 11th ribs. It is therefore located between the fundus of the stomach and the diaphragm.

What blood vessels serve the spleen?

When oxygenated blood is sent to the spleen, it is referred to be the splenic artery, or lienal artery for short. It arises from the celiac artery and travels in a superior direction to the pancreas. It is well-known for the circuitous course it takes to reach the spleen.

Where are antibodies produced spleen?

While the blood is filtered into the spleen, the sheaths that surround central arteries in the spleen contain T lymphocytes that target foreign bodies as they pass through the spleen. B-lymphocytes predominate in lymphatic nodules, where they produce antibodies that coat pathogens and mark them for removal by scavenger cells. B-lymphocytes are responsible for the production of antibodies.

What part of the spleen serves as a reservoir for lymphocytes and macrophages?

As major repositories for macrophages and other phagocytic white blood cells such as monocytes, the splenic cords in the red pulp of the spleen play a crucial role in the body’s defense against infection.

Does the spleen have lymphatic vessels?

The spleen is a component of the lymphatic system, which is a large drainage network that drains the body. This system is comprised of a network of lymphatic vessels that transport lymph, which is a clear, watery fluid that includes proteins, salts, and several other compounds, throughout the body.

What vessels supply the lymphatic vessels with blood?

Subclavian veins, which pump blood into the heart, serve as a connection between the vast lymphatic collecting vessels and the blood circulation. This vein links to the left subclavian vein, and this vein connects to the right subclavian vein through the ductus lymphaticus dexter (right subclavian vein).

Where are efferent vessels located?

From the lymph sinuses of the medullary section of the lymph nodes, the efferent lymphatic vessel emerges and exits the lymph nodes at the hilum, where it can be seen connecting to veins or larger lymph nodes. It is responsible for transporting filtered lymph out of the node. Efferent lymphatic vessels are also present in the thymus and spleen, but they are not as numerous.
