Mediastinal anatomy is complicated which is close to a number of important tissues and organs. Moreover‚ tissue biopsy is difficult. Hence‚ it is difficult to establish a diagnosis and differentiate benign from malignant lymph nodes. There are invasive and noninvasive methods for evaluation of enlarged mediastinal lymph nodes. Invasive methods contain mediastinoscopes‚ thoracoscopes‚ transbronchial needle aspiration (TBNA)‚ endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)

Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. The term anatomy refers to the structure and relationship of body parts such as tissues and organs. Physiology on the other hand is how these structures work as in individual and in the body as a whole. Take the circulatory system for example. The heart itself‚ blood vessels and blood is the anatomy. How these

1. Consider the equation F = DP/R. It describes the flow (F) of fluid in a tube in which there is a pressure difference (DP) between the two ends and a resistance (R) to flow. The equation indicates that(2.0 Score ) A.the flow of fluid from point A to point B in a tube depends upon the difference in pressure between A and B. B.the flow of fluid in a tube depends upon the absolute pressure at the beginning of the tube. C.the greater the resistance to flow in a tube‚ the greater the flow for any
