Question

The organ system responsible for delivering blood to the entire body is known as………………? explain with a diagram.

Answer 1

Hint: The circulatory system is usually referred to as the cardiovascular system. This system is consisting of three independent systems that work together for the working of the body: the heart (cardiovascular), lungs (pulmonary), and also the arteries, veins, coronary, and portal vessels (systemic).

Complete solution:
A system that is made up of different blood vessels that carry blood away from and towards the heart is called the circulatory system. In the cardiovascular system, arteries carry blood faraway from the heart and veins carry blood back to the heart together with oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
It was known that the cardiovascular system is a type of network of cylindrical vessels (the arteries, veins, and capillaries) that emanate from a pump (the heart), altogether vertebrate organisms, also as some invertebrates, a closed-loop are often found. In this type of circulatory system, the blood is not moving freely in a cavity as it is contained inside blood vessels, circulating unidirectionally (in one direction) from the heart around the systemic circulatory route,after that returning to the heart again. In contrast with a closed system, an open circulatory system is seen in arthropods (including insects, crustaceans, and most mollusks). The blood is not enclosed in the blood vessels, the fact is that it is pumped into a cavity called a hemocoel in an open circulatory system. Here the blood is commonly known as hemolymph because it mixes with the interstitial fluid. This hemolymph circulates the organs within the body cavity as the heartbeats and the animal moves, reentering the heart through openings called Ostia. During this movement gases and nutrients are allowed to exchange. This system does not use as much energy to operate and maintain as a closed system.


Note:
Some diseases that can affect the circulatory system includes atherosclerosis, hardening of the arteries, Heart attack, Mitral valve prolapse, Mitral valve regurgitation, Angina pectoris, Arrhythmia, and dysrhythmia, Cardiac Ischemia, etc.
