Question

What feature of an epithelial tissue would be well suited to the rapid diffusion of material from one fluid (such as blood) to another (such as interstitial fluid)?

a single layer of flattened cells

large cube shaped cells

loosely connected cells in an extracellular matrix

many layers of cells forming a thick stack

All of the following are matched correctly except one. Choose the exception. (i.e. choose the one that is not matched correctly)

erythrocytes - blood

mucus secreting cells - epithelium

mineralized matrix – cartilage

relatively small proportion of cells and matrix - dense fibrous connective tissue

lipid filled cells - adipose

Answer 1

A. Epithelial cells are found almost every where in the body and there function are also different in different places.Now in case of blood cells the epihelial cells are called simple squamous epithelium they are flattened single cell layer.They allow material to pass through diffusion. a single layer of flattened cells: True as the blood vessels are single layer cell.

large cube shaped cells: False because these type of cells are found in small glands and in the kidney.

loosely connected cells in an extracellular matrix: False because these type of cells are found in the urinary bladder and urethera

many layers of cells forming a thick stack: False because these type of cells are found in esophagues and mouth,

B.  relatively small proportion of cells and matrix - dense fibrous connective tissue

Because the these dense fibrous connective tissue is found tn large proportion iin the ligaments,tendons & in aponeurosis. So above this pair is wrong.
