Dendritic cells are a type of immune cell that play a key role in activating the immune system by capturing, processing, and presenting antigens to other immune cells. They act as messengers between the innate and adaptive immune systems, helping to initiate an immune response against invaders such as pathogens.
The flame-cell system in planarians consist of specialized cells called flame cells that are part of the excretory system. Flame cells have distinctive cilia that beat rapidly, creating a flickering appearance like a flame. These cells help regulate the osmotic balance and remove waste from the body by actively pumping fluids through the excretory system.

Circulatory system
The circulatory system.
The circulatory system carries nutrients and oxygen to body cells. In addition, it carries hormones and immune materials.
The circulatory system transports materials in the body.
Blood moves materials past cells, allowing for diffusion. It also moves cells themselves to places they are needed, as with immune system cells.

Similarities : used in circulatory system, transport materials, differences : arteries are thicker, and used to transport materials to the cells veins are thinner, and used to transport materials from the cells to areas of the excretory system.
Materials within a cell are transported by organelles such as vesicles and the endoplasmic reticulum. Between cells, materials are transported by the circulatory system, which includes blood vessels and the lymphatic system. Proteins such as transporters and channels also assist in transporting materials across cell membranes.
