Tissue Lab Relate and Review

Epithelium, ciliated columnar:
Covers body surface or lines body cavity; Some functions include protection and filtration. It creates a slippery surface. (left)

9 out of 12 of my drawings of the different types of
cells that we looked at under a microscope.

In this lab, I looked at 12 different types of tissues under a microscope. By learning about them and then looking at them, it helped me learn more and be more interested. It was very interesting to see the tissues and how they looked based on ideas such as the number of layers or the structure without having to look at it through a picture or diagram. Some of the most interesting tissues to look at and draw were the ones labeled " stratified squamous (top) dense irregular connective (bottom)" and "blood smear human". The first one was really cool because it showed how the epithelial and connective tissues blended together. The human blood smear sample was very pretty and looked simple. There were perfectly shaped ovals, circles, and peanut looking cells inside of this sample. I wouldn't think that blood looked that way especially because it was called a "smear". 

The different tissue types are connective, epithelial, muscle, and nervous. Connective tissue is " the most diverse and abundant" (Histology Part 1). It's main function is to bind together, strengthen, and support the other three tissues. Epithelial tissue covers body surfaces or lines body cavities. It's main function is protection. Muscle tissue has three types: skeletal, smooth, and cardiac. And nervous tissue "transmits electrical signals from sensory receptors to effectors" (Histology Part 2).

This lab made it both interesting and fun to look at the different types of tissues. i learned many things and it made it easier to remember by seeing visuals.
