| 2891404243 | What type of epithelium would you expect to find lining the alveoli (air sacs) in the lungs and why? | Since air must diffuse from the alveoli into the bloodstream, you would expect to find very thin cells, or squamous epithelium.

You volunteer to help her sort them out. How would you decide which slide is which? | Because animal intestine is modified for absorption, you would look for a slide that shows a single layer of epithelium lining the cavity. The cells would be cuboidal or columnar and would probably have microvilli on the surface to increase surface area. Because the esophagus receives undigested food, it would have a stratified epithelium consisting of squamous cells to protect it. | | 116 |
| 2891404251 | Analysis of a glandular secretion indicates that it contains some DNA, RNA, and membrane components such as phospholipids. What kind of secretion is this and why? | The presence of DNA, RNA, and membrane components suggest that the cell was destroyed during the process of secretion. This is consistent with a holocrine type of secretion. | | 117 |
| 2891404288 | Harriet had liposuction several years ago, but has since gained back all the weight lost through the procedure. She does not understand her weight gain because adipocytes are incapable of dividing. Provide a plausible explanation. | While it is true that adipocytes do not divide and the number of fat cells in peripheral tissues is limited, mesenchymal cells can divide and give rise to cells that differentiate into fat cells. Thus, areolar connective tissue can become adipose tissue in times of nutritional excess. Along with this, the fat cells that remain after surgery can enlarge by storing more tr iglyceride if the patient continues to overeat. | | 118 |
| 2891404292 | Cartilage heals poorly and in many instances does not heal or recover at all after a severe injury. Why not? | Cartilage lacks blood vessels, because chondrocytes produce a substance that inhibits the formation of blood vessels. This limits nutrient and oxygen delivery. Furthermore, adult chondrocytes are terminally differentiated and can't divide so no more interstitial growth occurs. Both avascularity and lack of cell division combine to minimize cartilage healing. | | 119 |
| 2891404296 | Which is likely to heal faster, a bone injury or a cartilage injury? Why? | Bone injuries heal relatively quickly because of the good nutrient supply by way of nearby blood vessels and the canaliculi, whereas cartilage is supplied nutrients via diffusion from the outside, a far slower process. | | 120 |
| 2891404300 | Compare and contrast the three types of muscle tissue. List three similarities and three differences among them. | Similarities: All have contractile proteins; skeletal and cardiac have striations; cardiac and smooth are involuntary; cardiac and smooth are uninucleate.
Differences: Skeletal is voluntary; cardiac has intercalated discs; smooth is nonstriated; skeletal is multinucleate. | | 121 |
| 2891404306 | What is the difference between neurons and neuroglia? | Neurons are specialized to respond to chemical and electrical signals and communicate by propagating an electric impulse along their axon. Neuroglia are a diverse group of cell types within neural tissue that support, nourish, and protect neurons. | | 122 |
| 2891404311 | During the inflammatory process, blood vessels dilate. What does this accomplish? | It allows for increased blood flow for delivery of nutrients, oxygen, and defense cells and proteins and for the removal of waste products and debris from the site of injury. | | 123 |
