Sinusoid blood vessel

sinusoid, irregular tubular space for the passage of blood, taking the place of capillaries and venules in the liver, spleen, and bone marrow. The sinusoids form from branches of the portal vein in the liver and from arterioles (minute arteries) in other organs.

What is the function of sinusoids capillaries?

Sinusoid capillaries allow for the exchange of large molecules, even cells. They're able to do this because they have many larger gaps in their capillary wall, in addition to pores and small gaps. The surrounding basement membrane is also incomplete with openings in many places.

Where is the sinusoid located?

Sinusoids are found in the liver, lymphoid tissue, endocrine organs, and hematopoietic organs such as the bone marrow and the spleen. Sinusoids found within terminal villi of the placenta are not comparable to these; they possess a continuous endothelium and complete basal lamina.

What is capillary and sinusoids?

Sinusoids are a special type of capillary that have a wide diameter. These are found in the liver, spleen, lymph nodes, bone marrow and some endocrine glands. They can be continuous, fenestrated, or discontinuous.

What is the function of sinusoids in the liver?

In the liver the blood from the portal vein flows through a network of microscopic vessels called sinusoids in which the blood is relieved of worn-out red cells, bacteria, and other debris and in which nutrients are added to the blood or removed from it for storage.…
