The circulatory system includes a vertebrate's heart, vascular system, and blood. In the circulatory and vascular systems-cardiac and vascular-make up this system. The cardiovascular system has systemic and pulmonary branches. The third Some sources use cardiovascular and vascular systems interchangeably for the circulatory system. The network of blood vessels in the heart includes large elastic arteries and veins, smaller arterioles, capillaries that branch into venules, and extra veins. Due to their closed circulatory system, vertebrates' blood never leaves their blood vessels. Arthropods have open circulatory systems. Sponge and comb jellies are diploblasts without circulatory systems. The circulatory system delivers oxygen and nutrition to tissues and removes waste. Blood is plasma, red, white, and platelets. In addition to minerals and proteins, circulating nutrients contain hormones, gases like carbon dioxide and oxygen, and hemoglobin. These nutrients nourish cells, help the immune system fight illness, and maintain homeostasis by controlling pH and temperature. Animal circulatory and lymphatic systems work together. Supplemental routes help the lymphatic system remove excess plasma from tissues and restore it to blood circulation as lymph. Plasma is filtered from capillaries as cell interstitial fluid. For the circulatory system to hydrate the blood, the lymphatic system must be present. Both the immune and lymphatic systems are implicated. Open lymphatic circulation takes longer than closed blood circulation. Some term it a supplementary circulatory system.
