The cardiovascular system has three main functions: transport of oxygen, carbon dioxide and nutrients; clotting of open wounds The cardiovascular system consists of the heart, blood vessels, and blood. Functions of the cardiovascular system Blood circulates through a network of vessels throughout the body to provide individual cells with oxygen and nutrients and helps dispose of metabolic wastes. The blood carries oxygen and nutrients to every cell of the body. The cardiovascular system circulates blood throughout your body to transport oxygen and carbon dioxide, nutrients, hormones, and cells to all your organs and tissues. Blood cells are made up of three parts, and each part has a job to do when it comes to protecting your body from infection or illness. The cardiovascular system circulates oxygen and nutrients throughout the body. The Blood Vessels

• The cardiovascular system has three types of blood vessels:

• Arteries (and arterioles) – carry blood away from the heart

• Capillaries – where nutrient and gas exchange occur

• Veins (and venules) – carry blood toward the heart. The arterial circulation delivers blood from the heart to the body, and the venous circulation carries it back to the heart. The cardiovascular system consists of the heart and blood vessels. Clotting mechanisms are also present that protect the body from blood loss after injuries. The heart is the organ that supplies blood and oxygen to all parts of the body.

Your blood vessels might also constrict or expand, thus allowing more or less of the body's fluids to be lost through sweat. The atrioventricular (mitral and tricuspid) and semilunar (aortic and pulmonic) valves keep blood flowing in one direction through the heart, and valves in large veins keep blood flowing back toward the heart. Blood in the veins is low in oxygen (as it has been taken out by the body) and high in carbon dioxide (as the body has unloaded it back into the blood). Protection. of the body by white blood cells, antibodies, and complement proteins that circulate in the blood and defend the body against foreign microbes and toxins. This system of transportation is the same kind of system that makes up the cardiovascular system. Removing #book# It works to transport oxygen and other nutrients to all the organs and tissues in … The primary function of the heart and blood vessels is to transport oxygen, nutrients, and byproducts of metabolism. Now picture even more roads, those that lead to small neighborhoods. It is a closed tubular system in which the blood is propelled by a muscular heart. The cardiovascular system, also known as the circulatory system, includes the heart, arteries, veins, capillaries and blood. o The major signal for calcium release from the SR is calcium entering through voltage-gated calcium channels in the plasma membrane during the action potential. Cardiovascular System. Oxygenated and nutrient rich blood is distributed to tissues via the arterial system, which branches into smaller and smaller blood vessels from arteries to arterioles to capillaries (where most exchange occurs). The function of the circulatory system is related to the transportation of cells and materials throughout the body. The used blood (low in oxygen) flows back in the veins towards the heart against gravity, where it passes through the superior vena cava and back into the right atrium. bookmarked pages associated with this title. This review highlights this critical physiological system by detailing the structure and function of the circulatory organs, including the dorsal heart and the accessory pulsatile organs that supply hemolymph to the appendages. The cardiovascular system is crucial in many other ways, not just in moving oxygen and blood around. Choose from 500 different sets of cardiovascular system function flashcards on Quizlet.
