LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses Adaptive immune response takes days or even weeks to become established—much longer than the innate response—and is more specific to pathogens and involves molecular memory. This…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses Much of the information about the different organ systems of vertebrate animals is not within the scope for AP®. The immune system, however, was chosen for…
Figure 33.1 In this compound light micrograph purple-stained neutrophil (upper left) and eosinophil (lower right) are white blood cells that float among red blood cells in this blood smear. Neutrophils provide an early, rapid, and nonspecific defense against invading pathogens. Eosinophils play…
Osmoregulation and Osmotic Balance Solute concentrations across a semi-permeable membranes influence the movement of water and solutes across the membrane. It is the number of solute molecules and not the molecular size that is important in osmosis. Osmoregulation and osmotic…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses As we learned in an earlier section, the excretory system works with the circulatory and endocrine systems to maintain osmotic balance, eliminate wastes, and maintain blood…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses Much information in this section is outside the scope for AP®. However, the concepts provide an opportunity to apply concepts explored in previous chapters, including chemistry.…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses The information in this section is not within the scope for AP® other than to appreciate that other organisms, including microorganisms and invertebrate animals, use more primitive…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses Much of the information in this section is outside the scope for AP®. Although the curriculum does not require you to have detailed knowledge about the…
LEARNING OBJECTIVES In this section, you will explore the following questions: Connection for AP® Courses Much of the information in this chapter is not within the scope for AP®. However, the chapter is filled with illustrative examples that are applicable to…
Figure 32.1 Just as humans recycle what we can and dump the remains into landfills, our bodies use and recycle what they can and excrete the remaining waste products. Our bodies’ complex systems have developed ways to treat waste and maintain a…
