Select all that are true of capillaries.Continuous capillaries are the most common type. Sinusoidal endothelial cells form a con
tinuous lining around the capillary lumen. Fenestrated capillaries allow for fast filtration and absorption. Sinusoidal capillaries are found in the bone marrow
The correct answers are a, c, d. There are three types of capillaries: continuous, sinusoidal (or discontinuous) and fenestrated. Continuous capillaries are the most common type and they form tight junctions. Sinusoidal capillaries form an incomplete lining with several gaps, which allow red and white blood cells and some serum proteins to pass. These capillaries are mainly found in the bone marrow, lymph nodes and adrenal glands. Finally, fenestrated capillaries facilitate the movement of smaller molecules and plasma proteins and are mainly found in the small intestine. The majority of the fluid transport happens through the fenestrated capillaries.
I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.
