the activation of the enzyme adenycyclase and an increase in concentration of cyclic AMP. The increase of cyclic AMP results in activating the protein kinase which lowers ionic calcium concentrations within the cells and stops the phosphorylation of myosin (12). This result is relaxation in the muscles, opening the airways and bringing an asthmatic patient relief. Albuterol relaxes smooth muscles from the trachea to the terminal bronchioles bringing about relief from any problems caused by…

In cell theory, it is known that all cells arise from pre-existing living cells, through cell division. In cell division, this involves the supplying of identical genetic material from the parent cell, DNA and protein, to two daughter cells. It results in the daughter cells having the same number of chromosomes as the parent cell. We need cell division as it is used in reproduction of new species, growth and repair of damaged cells and tissues, and to reduce the cell size. Larger cells are…

QUESTIONS 1. Discuss the pathophysiology of coronary artery atherosclerosis. Include discussion of risk factors associated with the development of this disease. (10 points) Coronary artery atherosclerosis is most commonly comprised of atherosclerotic fibrous fatty obstructions of the large epicardial vessels, which provide for blood flow and transport nutrients, oxygen, and elimination of metabolic waste products such as CO2, lactic acid, and hydrogen ions. Coronary artery atherosclerosis…
