An atriopore is a hole in a lancelet through which water exits the body.
Oxygen is moved through the body, bounded to hemaglobine (red blood cells). Glucose is moved through the blood.
Red blood cells are part of the blood and travel where the blood goes. Blood is moved through the heart to the lungs and back to the heart. Then it is moved through arteries to all the tissues of the body and back to the heart through the veins.
Blood cells and platelets are suspended in blood plasma (mostly water) and moved through the body in blood vessels (arteries, veins & capillaries). The blood is forced through the blood vessels by the heart.
like other cordates except urocortates, lancelet have closed-circulatory system.
In the circulatory system, the heart pumps blood through your body, like a fuel pump in your car. Blood is moved by the heart, which supplies blood to the liver, lungs, and all vital organs.
Oxygen is transported through the blood stream by Hemoglobin.
What it does it is, the heart is actually a muscle it squeezes out blood witch is moved throughout your body through your veins and arteries. That's what keeps the blood circulating around your body.
The atrial cavity in a lancelet serves as a space that facilitates the flow of water through the organism's body. It plays a crucial role in respiration and feeding by allowing water to pass over the gills, where gas exchange occurs and food particles can be filtered out. This cavity helps maintain the lancelet's simple body plan while supporting its basic physiological functions.
