Circulatory System â Opencurriculum The cardiovascular system shown in figure 1 is an organ system that moves nutrients, hormones, gases and wastes to and from body cells, and distributes heat to maintain homeostasis. the main components of the cardiovascular system are the heart, the blood vessels, and the blood. figure 1: the main organs of the circulatory system. An organ system* is a group of organs that act together to carry out complex interrelated functions, with each organ focusing on a part of the task. an example of an organ system is the human digestive system in which the mouth and esophagus ingests food, the stomach crushes and liquefies it, the pancreas and gall bladder make and release.
Circulatory System â Opencurriculum Homeostasis can be thought of as a dynamic equilibrium rather than a constant, unchanging state. feedback regulation loops. the endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. the release of hormones into the blood is controlled by a stimulus. The circulatory system is effectively a network of cylindrical vessels: the arteries, veins, and capillaries that emanate from a pump, the heart. in all vertebrate organisms, as well as some invertebrates, this is a closed loop system, in which the blood is not free in a cavity. The circulatory system brings blood to and from the body, while the cardiovascular system brings blood to and from the lungs only. true or false. arteries carry mainly oxygenated blood. name three different types of substances that are transported by the cardiovascular system. describe where and how the pulmonary and systemic circulation. Main features of the human circulatory system. a liquid, blood, to transport nutrients, wastes, oxygen and carbon dioxide, and hormones. two pumps (in a single heart): one to pump deoxygenated blood to the lungs and the other to pump oxygenated blood to all the other organs and tissues of the body. a system of blood vessels to distribute blood.

The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism. oxygen is bound to molecules called haemoglobin that are on the surface of the red blood cells in the blood. beginning in the heart, deoxygenated blood (containing carbon. Figure 40.2.1 40.2. 1: closed and open circulatory systems: (a) in closed circulatory systems, the heart pumps blood through vessels that are separate from the interstitial fluid of the body. most vertebrates and some invertebrates, such as this annelid earthworm, have a closed circulatory system. (b) in open circulatory systems, a fluid called.
