Your circulatory system helps regulate your temperature. When you are hot, capillaries just beneath your skin grow slightly wider to allow more blood to be near the surface of your skin and allow some body heat to escape. This is why your face is often red when your are very hot. When you are cold, the capillaries get slightly thinner. Less blood goes near the skin's surface, and less heat is lost.
The funtions of the cells that make up your body are: the skin tissue, the digestive system, and the circulatory system.

The defenses of the body, including the skin, immune system, digestive system, and circulatory system, are collectively referred to as the "immune system" or "defense systems." The skin acts as a physical barrier, while the immune system provides a complex network of cells and proteins that identify and eliminate pathogens. The digestive system also plays a role by using enzymes and acids to neutralize harmful microorganisms, and the circulatory system helps transport immune cells throughout the body. Together, these systems work in concert to protect the body from infections and diseases.
The skin is an organ by itself, but the circulatory system and nervous system both have direct connections with the skin (through capillaries in the case of circulatory and nerve endings in the case of nervous system.)

The earthworm's circulatory system, which consists of blood vessels, helps transport oxygen from its skin to its cells. The earthworm's respiratory system, which involves breathing through its skin, allows for the exchange of oxygen and carbon dioxide at the cellular level.
Yes, it lacks a circulatory system. It diffuses oxygen directly into its cells and diffuses carbon dioxide back out. That mechanism is why planarians need to keep their skin moist. On land, planarians secrete a thin layer of mucus to make diffusion easier.
Arthropods have an open circulatory system, with organs in the internal body cavity (hemocoel) and cells bathed in hemolymph. The fluid drains into open pores for recirculation usually by a dorsal tube acting in the role of a heart. Not all arthropods use hemolymph for oxygenation; insects for example oxygenate tissues directly via tubules connected through vents (spiracles) to the atmosphere.
No, it is not part of the circulatory system, it is protecting you from the environment, to help keep homeostasis( the body in stable condition)
The dermis is one of the layers of the skin. It is part of the integumentary system.
As firm and mean as this may sound, it is still true: Eventually the person whose circulatory system is not working is going to die, most likely some time in the next 30 minutes if you are lucky.
All organs are fed by the circulatory system. Examples include the skin, stomach, uterus, brain, kidneys, and spleen.
