Blood Vessels
Blood vessels are tubular structures that carry blood throughout the body, including arteries, veins, and capillaries, each serving distinct functions in the circulatory system.
Gametes
Reproductive cells (sperm in males and eggs in females) that fuse during fertilization to form a new organism with a complete set of genes.
Liver
A vital organ in vertebrates and some other animals that perform a wide range of functions including detoxification, protein synthesis, and production of biochemicals necessary for digestion.

Final Answer :
C
Explanation :
As we become older, our blood vessels become more rigid due to the gradual accumulation of plaque and other deposits on their walls, which can limit blood flow and increase the risk of heart disease and stroke. The elasticity of our skin decreases as we age, making it more prone to wrinkles and sagging. The heart typically increases in size rather than decreasing, and gamete production decreases and eventually stops in both sexes. The liver may receive increased blood flow due to changes in metabolism and other factors, but this is not a universal or consistent feature of aging.
