A You observe a uniform tissue under a microscope. There is no lumen. The material looks densely packed, but you do not observe many nuclei. It appears that there are strands of fibers running in parallel directions. What type of tissue are you looking at

Connective Tissue.

In the absence of lumen, without much arguments, it looks like a densely packed connective tissue. t possesses a low cell count when it is been compared to the extracellular matrix.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
