This lab was mostly a review lab for me, mostly reaffirming my knowledge (just in time for the unit 1 test), while also going a little bit more in depth than the cursory descriptive terms, such as squamous, cuboidal, columnar, stratification, and physical characteristics like nucleus count. Instead, using the slide names and posters, seeing which tissue structures were in each different regions or organs of the body allowed me to further understand the relations between the structure and function of the cell arrangements. For example, the connective tissue in the form of red and white blood cells on the "blood smear; human" sample revealed small, but circular red blood cells to create the most volume out of limited surface area and optimize the supply of oxygen moving around the bloodstream. In contrast, the slightly larger white blood cells were few and far between, but contained a visible dyed nucleus, showing its efficiency (with its large size) to engulf viruses and bacteria and use its nucleus to create immune cells. While connective blood cell tissue is spread apart between its cells, other tissues, especially the "stratified columnar epithelium; human" sample and the "human skeletal muscle" sample have little to no palpable space between cells, and thus confining the extra-cellular matrix to quick transport between cells and collagen fibers to strengthen the tissue's shape.
