Glands

Bronchi
Cartilage
The correct answer is Capillaries
So why is this answer correct? : Capillaries are the smallest blood vessels in the vascular system. They are found all over the body and perform many tasks, such as transporting blood, nutrients, and oxygen to organs. Capillaries also support many crucial organ systems. In the endocrine system, they deliver hormones to specific organs, and in the liver, they remove defective red blood cells and bacteria.
