Exam 20: Unifying Concepts of Animal Structure and Function

A leiomyoma is a benign tumor that affects smooth muscle. A large tumor of this type might be predicted to

What kind of connective tissue has an extracellular liquid matrix called plasma?

Which of the following tissues would likely be found in the small intestine?

The human wrist is very agile, but because of this agility it is also very prone to injuries involving the tissue connecting the wrist bones. This statement illustrates that animal structures

Epithelial tissues

Which of the following is a type of connective tissue?

Which of the following is an example of positive feedback?

The structural and functional unit of nervous tissue is the

Which layer of the skin lacks connective tissue?

An organ represents a higher level of structure than the tissues composing it, and it performs functions that the tissues cannot perform alone. This is an example of the principle of

Bioengineering to create organs for transplants involves

Structure in the living world is organized into hierarchical levels. Which of the following correctly lists these from least inclusive to most inclusive?

A leading motivation for scientists to bioengineer human organs for transplant is the trend in the percentage of patients on the organ transplant waiting list who receive a transplant (that is, [Number receiving transplant/Number on the wait list] × 100), as shown in this graph. Furthermore, although ethnic groups generally donate in proportion to their group's representation in the U.S. population, the need for particular organs in some groups is much higher than in others. For example, chronic kidney disease is three times more common in African Americans, Asians and Pacific Islanders, and Hispanics/Latinos as compared to Caucasians. Although organ compatibility is based on blood type and tissue markers, and not ethnicity, a compatible match is more likely between people of the same ethnic group (that is, with greater genetic similarity). Thus, bioengineering of human organs can also potentially solve the problem of decreased access to organ transplants among diverse groups of people. Change in percent of organ transplant waiting list who receive a transplant -Imagine that fully functioning kidneys have been successfully created through bioengineering. What data analysis would measure the effectiveness of bioengineered organs in improving access to organ transplants among diverse groups of people?

Unlike both smooth and skeletal muscle, cardiac muscle has cells that

Change in percent of organ transplant waiting list who receive a transplant -What is the best explanation for the trend in the percentage of patients on the organ transplant waiting list who receive a transplant, and how can bioengineering help to reverse this trend?

-Which type of epithelial tissue shown is a stratified tissue?

Structure in the living world is organized into hierarchical levels. Which of the following correctly lists these from least inclusive to most inclusive?

Which is the most abundant kind of tissue in an animal, such as a gorilla?

Which organ system removes nitrogen-containing waste products from blood?

The human spine acts like a weight-bearing column. Compare this to the spine of a horse, which acts like an elastic suspension bridge. Which organism would you predict to experience more back pain and why?
