NR 565 Advanced Pharmacology Midterm Week 1: Principles of Pharmacology  Pharmacokinetics, pharmacodynamics, and drug interactions o Pharmacokinetics is the study of drug absorption, distribution, metabolism, and excretion in the body. o For drug absorption to occur, a drug must penetrate cellular membranes to cross biological barriers. The process entails passive diffusion whereby drugs move from a higher concentration area to a lower concentration area by diffusing through cell memb...

BIOS255 – Week 6: Case Study The respiratory system is divided into the upper respiratory tract (URT) and lower respiratory tract (LRT). The URT consists of organs in the head and neck and is generally lined with a pseudostratified ciliated columnar epithelium. The LRT consists of respiratory organs in the thorax and transitions from pseudostratified ciliated columnar epithelium to simple squamous epithelium. The respiratory system can also be divided into two main zones: the conducting zone...

BIOS255 – Week 7 Case Study The respiratory system is a complex network of organs and tissues responsible for supplying oxygen to the body's cells and removing carbon dioxide. However, exposure to certain gases, such as carbon monoxide (CO), can disrupt this delicate balance. CO binds to hemoglobin in red blood cells, preventing oxygen from reaching vital organs and tissues, leading to tissue hypoxia and cellular damage. Patient Background: Lucas, a 45-year-old man, is brought to the eme...

1. What is innate immunity? Innate immunity is the body’s built-in, first-line defense system that is present from birth. It’s nonspecific — meaning it reacts to any invader, not just a specific pathogen — and responds within minutes to hours. It includes: • Physical barriers (skin, mucous membranes) • Chemical barriers (stomach acid, lysozyme in tears/saliva) • Cellular defenses (phagocytes, natural killer cells) • Inflammatory response (swelling, redness, heat, pain) In...

1. What is the definition of "pathophysiology"? Pathophysiology is the study of how normal physiological processes are altered by disease or injury. 2. 2. Name the 5 etiologic factors and give an example if listed. • Biologic agents – bacteria, viruses, parasites (e.g., Streptococcus pneumoniae) • Physical forces – trauma, burns, radiation • Chemical agents – toxins, alcohol, drugs • Genetic disorders – inherited mutations (e.g., sickle cell anemia) • Nutritional e...

1. A bodybuilder's muscles will display hyperplasia. Answer: False Explanation:  Bodybuilders experience hypertrophy (increase in muscle fiber size), not hyperplasia (increase in cell number). **Arnold received a huge trophy for getting huge hypertrophy muscles**  Hyperplasia occurs in tissues with high cell turnover (e.g., uterine lining during pregnancy, wound healing). Memory Tip: “Hyper = more cells, Hypertrophy = bigger cells.” 2. Barrett esophagus is an example of dy...
