Is circulating blood a function of the nervous system?
While the nervous system controls the pumping of the heart as well as neurotransmitters and hormones that control vasodilation and vasocontraction, the circulatory system is primarily responsible for circulating blood throughout the body.
Why does the earthworm have a closed circulatory system?
The earthworm like many more complex organisms has a closed circulatory system, meaning that its blood is confined to blood vessels and its blood is recirculated so it gets maximum use

What organs work together with the Respiratory System to work properly?
-------
Below answer by a doctor:
Ultimately all organs rely on the respiratory system as it is the system that removes waste carbon dioxide and provides oxygen. Oxygen is used by the body to enable the production of energy. Energy is used by all organ systems and tissues for the functioningy of the body. The organs of the respiratory system are; the lungs, the diaphragm, the heart, the circulatory system, the blood. There are two types commonly considered to be "respiration" 1) the act of breathing in and out which is actually medically called "ventilation", and 2) cellular respiration that occurs within the cell and produces energy.
How can a person lifestyle affect the performance of respiratory and circulatory systems?
Smoking, lack of exercise, lack of attention to Asthma, and exposure to irritants such as dust can all affect the performance of the respiratory and circulatory systems.
What sends blood to heart from upper body?
Veins always carry blood to the heart. Most carry blood low in oxygen but some don't. The term artery and vein are anatomical terms only. Here is a list: internal jugular (from head), left and right subclavian (from upper chest), brachiocephalic (from arm and face), and superior vena cava.

How can homeostasis in the circulatory system get unbalanced?
== == Nutrients and other essential materials pass from capillary blood into fluids surrounding the cells as waste products are removed. A couple of control mechanisms help regulate the diverse functions and component parts of the cardiovascular system in order to supply blood to specific body parts according to need. These mechanisms ensure a constant internal environment surrounding each body cell regardless of differing demands for nutrients or production of waste products. The circulatory system helps to maintain homeostasis by interacting with the digestive system. Homeostasis maintains the stability of the human body's internal environment in response to outside changes in external conditions.
What does the circulatory system do in the aye-aye's body?
The circulatory system performs the same function in all animals. It circulates blood, which carries nutrients and oxygen to the cells while carrying away wastes and carbon dioxide.
How does the circulatory system help people?
The Circulatory System helps us by your body needing cells. Also nutrients and oxygen removes waste from your body.As blood is pumped out of the heart it travels through arteries capillaries and then veins.
Could you live without an organ called a circulatory system?
