Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The vessels that exhibit the lowest level of permeability are the ____
A
continuous capillaries
B
fenestrated capillaries
C
sinusoidal capillaries
D
None of the above
Explanation: 

Detailed explanation-1: -Continuous capillaries are the least permeable type of capillary, allowing only small solutes to pass across the capillary wall. These are found in areas such as the brain, lungs, and muscles. Fenestrated capillaries contain pores or fenestrations and are more permeable than continuous capillaries.

Detailed explanation-2: -Fenestrated capillaries The ‘fenestrations’ are pores that will allow larger molecules though. These capillaries are more permeable than continuous capillaries.

Detailed explanation-3: -As a result, sinusoids are considerably more permeable and are capable of considerable rapid nutrient exchange. Endothelial cells lining hepatic sinusoids are interspersed by macrophages, which have an important phagocytic function. Figure 7. A majority of capillaries exhibit a continuous structure.

Detailed explanation-4: -Capillaries are small enough to penetrate body tissues, allowing oxygen, nutrients, and waste products to be exchanged between tissues and the blood.
