The main organ in the circulatory system is the heart, according to Hillendale Health. The two other major parts of the circulatory system are the blood and the blood vessels.Know More
The heart is found slightly to the left at the center of the chest, and it is primarily responsible for pumping blood and keeping the blood moving throughout the body, explains Hillendale Health. Blood is a substance that constantly flows throughout the body, and it is pumped by the heart. It travels through blood vessels and brings water, oxygen, nutrients and waste products to and from the body cells. It consists of liquids, solids and small amounts of oxygen and carbon dioxide.
Clinton Community College explains that the heart is composed of two separate pumps. The right side pumps blood to the lungs, while the left side pumps blood to the body. Both sides have an atrium and a ventricle. The function of the atria is to receive blood while they are relaxed and fill the ventricles as they contract, whereas the ventricles pump blood to the body and lungs.
The main job of the circulatory system is to transport materials throughout the body, says Hillendale Health. The system travels through the entire body and connects all body cells.Learn More
The main function of the circulatory system is transporting blood, oxygen, hormones, nutrients and other important substances throughout the body. The circulatory system is actually two separate systems of circulation, pulmonary and systemic, both of which interact with the heart and cardiovascular system to pump blood throughout that system.Full Answer >
The skeletal system works constantly with the muscular system, and the circulatory system, endocrine system and integumentary system also have interactions with it. The skeletal system provides vital support and protection for all the other systems of the human body.Full Answer >
The respiratory system helps maintain homeostasis by regulating the intake of air into the body and by removing carbon dioxide from the blood, which in turn assists the circulatory system's function and many other operations in the body. Homeostasis is the overall equilibrium of the body's internal organs and functions. Without these internal systems being properly balanced it can lead to a number of issues in the human body, including death, depending on the severity of the imbalance.Full Answer >
Large animals need a circulatory system because the cells in the interior of their bodies are too distant from the surface for absorbed oxygen to diffuse to them sufficiently. By circulating fluid carrying oxygen to these deeper areas, the distance oxygen has to diffuse is greatly reduced.Full Answer >
