DATE: 3/21/2024HISTOLOGY OF THE CIRCULATORY SYSTEM:
Summary of Key Points on the Circulatory System:Heart:
– The heart is composed of three main layers: the inner endocardium, the myocardium, and the outer epicardium.
– Rhythmic contractions are initiated by the cardiac conducting system, comprised of specialized muscle fibers including the SA and AV nodes, bundle branches, and Purkinje fibers.
– Purkinje fibers, found in the ventricles, are distinguished by their size, glycogen content, and arrangement of myofibrils.
– Dense irregular connective tissue forms the cardiac skeleton, supporting heart valves and providing attachment points for cardiac muscle.Vasculature:
– Blood vessels have three layers: intima, media, and adventitia, each with distinct compositions and functions.
– Endothelial cells within vessels play active roles in regulating blood clotting, smooth muscle contraction, and inflammation.
– Arteries are categorized by size and wall composition, ranging from large elastic arteries to small muscular arteries.
– Microvasculature includes arterioles, capillaries, and venules, facilitating metabolic exchange in tissues.
– Terminal arterioles connect to capillary beds, where metabolic exchange occurs.
– Capillaries exhibit different structures and functions, influencing the extent of molecular exchange.
– Venules drain capillary beds, serving as entry points for white blood cells into tissues.
– Pericytes, thin cells surrounding endothelial cells, contribute to vascular function.Paraphrased from:

MT30 LEC – CCWHAT IS HISTOLOGY ART?
Discover the Beauty of Histology Art“Histology Art” was crafted to celebrate and explore the beauty of histology; it is not intended for use as a learning tool for histology. Special histology stains or histology immunohistochemistry techniques were not employed in the creation of the histology art images. Instead, digital editing was utilized to bring these histology art images to life.
LESSON LEARNED:
Imagine yourself building a clinical laboratory with abundant financial resources and a dedicated team willing to invest. During the planning stage, you have numerous creative ideas on how to effectively manage the laboratory and achieve your vision of becoming a leading global healthcare provider. However, you find yourself stuck in the middle, unsure of how to fully maximize your resources, implement you’re creative ideas, and work with a limited staff. It is at this point that you recall the valuable lessons you learned in your MT14 Health and Information System for Med Lab Science class, which taught you about managing, building, and creating a comprehensive health information system.Health Information Systems for Med Lab Science is a fundamental aspect of our current profession as medical technologists and will be crucial if we decide to establish our own clinical laboratory in the future. From this class, I have learned three important lessons that will guide me on my journey. Firstly, I have learned the importance of selecting an appropriate, cost-efficient, user-friendly, and reliable Laboratory Information System (LIS), as it serves as a fundamental component of the healthcare system. An LIS enables easy access to data and files, provides readily available test results, and facilitates the efficient storage of patient information. Secondly, I have gained an understanding of the different functions and roles of allied healthcare workers who collaborate to deliver quality services in a clinical laboratory. Additionally, I learned about the significance of properly determining salary grades for these professionals. It is important to recognize the contributions of each member of the team and ensure fair compensation.
Furthermore, in creating a clinical laboratory, I have learned about the importance of implementing procedures, processes, and policies in conjunction with material management. Adhering to these guidelines ensures smooth operations and regulatory compliance. Lastly, I have acquired knowledge about quality assurance, which emphasizes the importance of maintaining reliability, performance, and a focus on providing confident and high-quality services. Implementing quality assurance measures guarantees that the laboratory meets rigorous quality requirements and provides accurate and reliable results to healthcare providers and patients. By applying these lessons, I am confident that I will be better equipped to build and manage a successful clinical laboratory, ensuring efficient data management, effective teamwork, adherence to procedures, and a commitment to quality assurance.
POLICY – A policy is a guideline or direction of a firm that offers guidance to employees, departments, and the entire organization. It functions as a procedural handbook and ensures consistency and conformity to the organization’s mission, values, and strategic goals. The bulk of the time, upper management develops policies and utilizes them as a guide for decision-making. You should define the aim of a policy, its reason for being, the department under which it falls, and those in responsibility of implementing and enforcing it.
PROCESS – A process spans departments and describes how to create a product or service. It adheres to the company’s standards or policies while providing a high-level overview of how something should function. Within a process, you should specify who is in charge of carrying it out, what tasks should be completed, and when they should be completed.
Procedure – Whereas a process provides a general picture, a procedure is more specialized and provides step-by-step instructions on how to carry out a particular activity or a particular portion of a process. Employee input is frequently sought when developing procedures since employees utilize them the most; procedures are the operational implementations of policies developed by senior management. A procedure should specify who does it, the actions that are taken, when they are taken, and how they are taken.
