THat is just how our body works. The red marrow produces blood cells and clotting factors and the yellow marrow is stores fat, these marrows are important parts of our circulatory system
Yellow bone marrow contains and is made up of fat globules and capillaries. It also contains numerous blood vessels. If yellow bone marrow seeps into the blood stream it can be deadly.
There are two types of bone marrow: red marrow (consisting mainly of myeloid tissue) and yellow marrow (consisting mainly of fat cells). Red blood cells, platelets and most white blood cells arise in red marrow. Both types of bone marrow contain numerous blood vessels and capillaries.
There are two types of bone marrow: red marrow(consisting mainly of hematopoietic) tissue and yellow marrow (consisting mainly of fat cells).Red Blood Cels, platelets, and most white blood cells arise in red marrow. Both types of bone marrow contain numerous blood vessels and capillaries.
Sinusoidal capillaries...these are wide leaky capillaries found in bone marrow
no capillaries connect the arteries to the vain bone marrow makes rbcs
because the amount of fluid that get out from capillaries are low,,,,as we know the lymphatic vessels drain the excess amount of fluid that gets out from capillaries,,,so in bone marrow there is no high amount of fluid so there is no need to have lymphatic drainage :))
The smallest vessels in the lymphatic system are called lymphatic capillaries. These vessels are responsible for collecting excess fluid, proteins, and waste products from the tissues and returning them to the bloodstream.
Sinusoidal Capillaries
The small vessels located in the liver, spleen, and bone marrow are called sinusoids. These specialized capillaries have a wider diameter and more permeable walls compared to regular capillaries, allowing for the exchange of larger molecules and cells. Sinusoids play a crucial role in filtering blood and supporting the function of the organs they are found in.
A vessel that, unlike a blood vessel, carries fluid only away from tissues. This fluid is a pale, watery substance known as lymph.The smallest lymph vessels are the lymph capillaries, which begin in the tissue spaces as blind-ended sacs. Lymph capillaries are found in all regions of the body except the bone marrow, central nervous system, and tissues, such as the epidermis, that lack blood vessels. They are especially numerous in the loose connective tissues under the epithelium of the skin and mucous membranes.
Leaky capillaries found in the bone marrow are called sinusoidal capillaries. These specialized capillaries allow larger cells like blood cells to move in and out of the bloodstream more easily due to their larger size and more permeable nature. This facilitates the movement of cells between the bone marrow and blood circulation.
