3. The fascia adherens component.

4. The aorta has a tunica media dominated by elastic tissue. The elasticity conferred by elastin allows these elastic arteries to smooth out the sharp changes in blood pressure resulting from the pumping heart.

5. An artery would have a larger lumen than its corresponding vein. With such relatively thin walls, veins tend to appear flattened or collapsed in contrast to arteries, which tend to appear more round.

6. The tunica media and tunica adventitia would not be presents in a capillary for the reason that

Respiratory Tissue Review

1. Respiratory Epithelium contains serous and mucous glands, these reflect the functions of the nasal mucosa, to warm and humidify the incoming air.

2. Gas exchange occur in bronchi since it occurs in the capillaries which are found in the alveoli sacs

3. The primary functional unit of the lung is the acinus which includes all of the structures of the respiratory portion of the lung namely the respiratory bronchiole, the alveolar ducts and alveolar sacs.

4. Smooth muscle is not present in the alveolar wall for the reason that it would interfere with gas exchange.

5. The three basic components of the air-blood barrier are the type I epithelial cell, capillary endothelial cell and the fused basal laminae of type I cell and the endothelial cell.

Digestive Tissue...

Salivary glands are exocrine glands
2. Serous cells produce a thin and watery salivary secretion.

3. The adventitia is a very pale connective tissue and unlike a serosa, an adventitia just merges with surrounding connective tissue and has no finished edge of mesothelium.

4. The surface mucous cells cover the luminal surface of the stomach and line the gastric pits.

5. It helps to neutralize the acidic chyme and to protect the duodenal mucosa from auto digestion.

6. Goblet cells produce mucin for lubrication of the intestinal contents and protection of the epithelium.

7. The phagocytic Kupffer cell is an endothelial cell.

8. Blood in the portal vein flows directly from the gastrointestinal tract and the spleen.

9. Bile is a secretion product that aids digestion by emulsifying dietary lipids.

Renal Tissue Review

1. In the proximal tubule segment

2. The proximal convoluted tubule cells is similar to the entorocytes of the small intestine by being both

3. The three layers are the glomerular capillary endothelium, glomerular basement membrane, and visceral layer of Bowman's capsule.

4. It would not be present because it is too big to be filtered.

5. Another function is to move the carbon dioxide and waste products out of the cell back into circulation.
