How does lack of subcutaneous tissue affect someone's sensitivity to cold environmental temperature?
The subcutaneous tissue is the where the adipose tissue resides and offers insulation. Lack of this insulation will cause sensitivity to cold environmental temperatures.
Why is there no cartilage in the alveoli?
The alveoli, which are the tiny air sacs in the lungs where gas exchange occurs, lack cartilage because they need to be flexible and compliant to facilitate the expansion and contraction during breathing. Cartilage is rigid and would restrict this necessary flexibility. Instead, alveoli are supported by elastic fibers and a thin layer of connective tissue, allowing them to maintain their shape while enabling efficient gas exchange. This design optimizes their function in respiration.
