AMEDD Anatomy and Physiology Course a human stomach is an example of which of the following structural levels of organization - organ A positive feedback system does which of the following? - Strengthens or reinforces a change in a controlled condition after the reaction is completed and the reaction products move away from the enzyme, what happens to the enzyme? - the enzyme molecules break down and are absorbed an acute viral infection may cause what kind of white blood cell reaction - an increase in the number of large lymphocytes Anatomy can be defined as the study of which of the following? - Parts of the body at the cellular level, which of the terms describes an attribute of development from a single cell to a functioning organism - highly variable blood plasma is mostly made up of what substance - antibodyies cellular level - includes cells, which are composed of chemicals and molecules Chemical Level - Includes atoms and molecules chemicals move from an area of higher concentration to lower concentration across the plasma membrane due to which of the following mechanisms - electrical gradient during cell division, in what stage of interphase does replication of most organelles and cytosolic components occur - G2 (gap or growth) during interphase, what takes place during the synthesis (S) stage of cell division - centromeres are synthesized during the metaphase stage of cell division, what happens to the chromatid pairs - identical chromosome sets at opposite poles uncoil and revert to threadlike chromatin form eight chemical elements constitute 3.6 percent of total body mass. what are these chemical elements called? - trace chemical elements endothelial cells display adhesion molecules in response to nearby injury or inflammation. What is the name for these adhesion molecules - heparins Homeostasis is the ___1__ of the body's internal environment. The nervous system uses electrical signals called___2____ to transmit instructions that help bring back equilibrium. The endocrine system does the same by using glands to send out molecular messengers known as ____3___. The nervous and endocrine system maintain homeostasis by triggering ___4___. - 1. equilibrium 2. nerve impulses 3. hormones 4. feedback systems how are white blood cells classified - leukocyte or lymphocyte in a centrifuged sample of blood, what component is seen at the top? - plasma In a negative feedback system in which high blood pressure is detected and reduced to restore homeostasis, which of the following steps represents the action of effectors? - Heart rate slows and blood vessels dilate, decreasing blood pressure. in carrier-mediated facilitated diffusion, what term describes what happens when a specific solute binds to a specific carrier (integral protein) - gated in channel-mediated facilitated diffusion, most of the channels are of what kind - sodium channels in channel-mediated facilitated diffusion, what term describes part of an integral protein and its function during diffusion of substances through the cells membrane - concentration gradient in diffusion, how will smaller molecules behave compared to larger molecules - they will diffuse more rapidly In order from smallest to largest - chemical, cellular, tissue, organ, system, organism in simple diffusion, how do substances move through the lipid bilayer of the plasma membrane - freely in the cycle of cell division there is the mitotic period and what other period - prophase in the transport process of endocytosis, what is used to form th
