The Circulatory System
The circulatory system usually works in close association with the respiratory system except, as previously noted, in insects.
Circulatory System
Just like a city with hallways, and roads, your body has blood vessels, arteries, and veins that help move things around. Most of the cells inside of your body do not move.
The circulatory system functions in the delivery of oxygen, nutrient molecules, and hormones and the removal of carbon dioxide, ammonia and other metabolic wastes. Capillaries are the points of exchange between the blood and surrounding tissues.
Animal Circulatory Systems
An efficient circulatory system has:
a fluid, e.g., blood, to carry the materials to be transported;
a system of vessels to distribute the blood;
a pump to push the blood through the system; ...
The core components of your circulatory system are the heart and vessels. You happen to have a four-chambered heart while other organisms may have one, two, or three chambers. The heart is the pump for the system.
circulatory system One of eleven major body organ systems in animals; transports oxygen, carbon dioxide, nutrients, and waste products between cells and the respiratory system and carries chemical signals from the endocrine system; ...
open circulatory system
