Answer the following question given this paragraph: 39.3 | Breathing By the end of this section, you will be able to: Describe how the structures of the lungs and thoracic cavity control the mechanics of breathing Explain the importance of compliance and resistance in the lungs Discuss problems that may arise due to a V/Q mismatch Mammalian lungs are located in the thoracic cavity where they are surrounded and protected by the rib cage, intercostal muscles, and bound by the chest wall. The bottom of the lungs is contained by the diaphragm, a skeletal muscle that facilitates breathing. Breathing requires the coordination of the lungs, the chest wall, and most importantly, the diaphragm. Q: Mammalian lungs are located in what cavity, where they are surrounded and protected by the rib cage, intercostal muscles, and chest wall? Choices: - ventral - abdominopelvic - dorsal - thoracic A:
thoracic
Answer the following question given this paragraph: In the equation for pressure, force is expressed in newtons (N) and area is expressed in square meters (m 2 ). Therefore, pressure is expressed in N/m 2 , which is the SI unit for pressure. This unit is also called the pascal (Pa) . It is named for the scientist Blaise Pascal, whose discovery about pressure in fluids is described later in this lesson. Pressure may also be expressed in the kilopascal (kPa), which equals 1000 pascals. For example, the correct air pressure inside a mountain bike tire is usually about 200 kPa. Q: In the equation for pressure, how is force expressed? Choices: - meters - pounds - teraflops - newtons A:
newtons
Q: Answer the following question given this paragraph: The brain serves as the control center of the nervous system and the body as a whole. It lets us understand what we see, hear, or sense in other ways. It allows us to learn, think, remember, and use language. It controls all the organs and muscles in our body. Q: What serves as the control center of the nervous system? Choices: - spine - bone - heart - brain A:
A: brain
Question: Answer the following question given this paragraph: Like boys, girls also go through an adolescent growth spurt . However, girls typically start their growth spurt a year or two earlier than boys (and therefore a couple of centimeters shorter, on average). Girls also have a shorter growth spurt. For example, they typically reach their adult height by about age 15. In addition, girls generally do not grow as fast as boys do during the growth spurt, even at their peak rate of growth. As a result, females are about 10 centimeters (about 4 inches) shorter, on average, than males by the time they reach their final height. Q: Which gender typically experiences growth spurts first? Choices: - no difference - male - transgender - female A:
Answer: female
*Question*
Answer the following question given this paragraph: The cerebrum is divided into a right and left half ( Figure above ). Each half of the cerebrum is called a hemisphere. The two hemispheres are connected by a thick bundle of axons called the corpus callosum . It lies deep inside the brain and carries messages back and forth between the two hemispheres. Q: What is each half of the cerebrum called? Choices: - demisphere - a describe - a biplane - a hemisphere A:
**Answer**
a hemisphere

Answer the following question given this paragraph: in animals but also in plants. An organ system is a higher level of organization that consists of functionally related organs. Mammals have many organ systems. For instance, the circulatory system transports blood through the body and to and from the lungs; it includes organs such as the heart and blood vessels. Organisms are individual living entities. For example, each tree in a forest is an organism. Single-celled prokaryotes and single-celled eukaryotes are also considered organisms and are typically referred to as microorganisms. All the individuals of a species living within a specific area are collectively called a population. For example, a forest may include many pine trees. All of these pine trees represent the population of pine trees in this forest. Different populations may live in the same specific area. For example, the forest with the pine trees includes populations of flowering plants and also insects and microbial populations. A community is the sum of populations inhabiting a particular area. For instance, all of the trees, flowers, insects, and other populations in a forest form the forest's community. The forest itself is an ecosystem. An ecosystem consists of all the living things in a particular area together with the abiotic, non-living parts of that environment such as nitrogen in the soil or rain water. At the highest level of organization (Figure 1.16), the biosphere is the collection of all ecosystems, and it represents the zones of life on earth. It includes land, water, and even the atmosphere to a certain extent. Q: What organ system transports blood through the body and to and from the lungs? Choices: - metabolism - digestive - nervous - circulatory A:
(A).
circulatory
