Lymphatic capillaries are dead-end vessels interspersed between the vascular capillaries. They lack tight junctions between endothelial cells and therefore are more permeable to proteins than are vascular capillaries.
Yes, capillaries are permeable to proteins.
The lymphatic capillaries are small, thin-walled vessels that collect excess tissue fluid (lymph) from the interstitial spaces and return it to the bloodstream. This helps maintain fluid balance in the body and plays a crucial role in the immune system by transporting immune cells and proteins.
The Lymphatic System.
Yes, capillaries are permeable to proteins. This characteristic allows for the exchange of substances between the blood and surrounding tissues. Proteins can move in and out of capillaries, facilitating the transport of nutrients, hormones, and waste products throughout the circulatory system.
Only capillaries have permeable walls; veins and arteries are not permeable.
Lymphatic fluid, or lymph, originates from interstitial fluid, which is the fluid that surrounds cells in tissues. It is formed when excess fluid, proteins, and waste products from blood capillaries seep into the spaces between cells. The lymphatic system collects this fluid through lymphatic capillaries, which transport it through lymph nodes and eventually return it to the bloodstream.

Fenestrated capillaries
Lymph capillaries
lymphatic capillaries are very permeable Lymphatic capillaries have valves that keep fluid from flowing backward. The blood capillaries are regulated by smooth muscle. Lymphatic capillaries are also a but larger than blood capillaries.
Fat
Lymphatic vessels originate as blind-ended capillaries in the tissue spaces. These capillaries merge to form larger vessels that eventually join the lymphatic ducts, which return lymph fluid back to the bloodstream.
