1.5 Anatomy and Physiology
1.5.1 Circulatory System The main function of the circulatory system is to efficiently circulate blood, nutrients, and delivering oxygen to all of the body tissues while removing carbon dioxide and hormones (S. Whittemore & Cooley, 2009). The human circulatory system is a closed loop composed of two circulation pathways in series: the pulmonary and systemic pathways. Figure 2 illustrates the circulatory system as a closed loop system transporting blood to their respective locations. Figure 2. (A) The circulatory system consists of a series of veins, arteries, capillaries, arterioles, and venules that transfer blood to and from the heart. (B) Two major circuits of the circulatory system: Pulmonary circuit and Systemic Circuit (Sloane, 1994).
The pulmonary circulation system is a high-flow and low-pressure system that is influenced by pressures produced by the heart and thorax (Fishman, 1985). Pneumonic flow transports deoxygenated blood from the right ventricle of the heart to the pulmonary artery. The pulmonary artery divides into two smaller branches, each carrying deoxygenated blood to the respective lung (Bhise, 2008). The lung is the important link in transporting oxygen from the air to the blood. The lungs are large highly compliant vasculature beds where gas exchange occurs causing the oxygenation of blood. Four pulmonary veins collect the oxygenated blood from the right and left lung; decanting the blood into the left atrium (Bhise,
One of the most important systems in the body, keeping it alive, is the cardiovascular system. As a part of the circulatory system, the cardiovascular system pumps blood throughout the body through a network of many arteries and veins, providing it with nutrients and oxygen. Also, the cardiovascular fights infections and disease in the body and creates blood cells. Never the less, blood acts as a filtration system for the body and removes waste, cell debris, or bacteria from the bloodstream.
The cardiovascular system, which consists of the heart and blood vessels, is the circulatory systems in our body. The major function of the system is transportation; the heart is the system pump and the blood vessels are the delivery routes. The heart transport respiratory gases, nutrients, wastes, and other substances vital to the body’s homeostasis to and from the cells by using the blood as a medium.
Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.
The Circulatory system is responsible for the transport of blood throughout the body. The Circulatory system has many organs. The main components are the heart, the blood, and the blood vessels. It also consists of arteries, arterioles,
The cardiovascular system consists of the heart, blood vessels and 5 liters of blood that the blood vessels transport. The cardiovascular system is transporting oxygen, nutrients, hormones and cellular waste products through the body. The cardiovascular system is powered by the hardest working organ the heart.
Composed of various systems, the human body exists as a complex and sophisticated machine that carries out intricate tasks, crucial for life. The most vital of these is the circulatory system. The combination of the heart, lungs, arteries, and veins make up this highly important system. Transporting nutrients and oxygen to tissues and organs, while also discarding waste products remain the main purpose. Three separate systems, the cardiovascular, pulmonary, and systemic all work together with the sole intention of circulating blood and nutrients through the body. Through the beating of the heart, circulation to the lungs, and transportation of oxygen rich blood throughout the body, each human being has the ability to inhale and exhale effortlessly, while our body works efficiently to complete the essential task of the circulatory system. The circulatory system works in a cycle that repeats itself sixty to one hundred times a minute. A single complete heartbeat makes up one cardiac cycle (Toro).
The circulatory system, also called the cardiovascular system, distributes vital nutrients throughout the body. The main organs are the heart and the blood vessels that run throughout the entire human body. Blood runs through the entire body, in the blood vessels, and contains cells and plasma.
The circulatory system is by definition the system of organs and tissue, including the heart, blood, blood vessels, lymph, lymphatic vessels, and lymph glands involved in circulating blood and lymph through the body (Dictionary). However, the heart has a very specific function that is involved in the system; the heart 's function and parts will be broken down into detail in following paragraphs.
There are three main functions of the cardiovascular system are: transportation where the heart pumps the blood vessels through the delivery way. It has been argued by (Medical terminology for cancer, 2014) that heart transports the respiratory gases, nutrients, wastes, and other substances that are needed by the body’s homeostasis to and from the cells by using the blood.
Did you know the circulatory system comprises the heart, veins, capillaries and arteries? The system moves pure oxygenated blood in a continuous and controlled way from the lungs and heart so that blood can reaches every cell. Blood travels through a type of network of vessels that include capillaries that permeate every tissue of the body. Once it’s depleted of oxygen, the blood returns to the lungs and heart and the cycle continues.
Main components of the circulatory system are the heart, blood vessels, and blood. The heart helps pump blood throughout the body, the functions are to transport oxygen as well as blood from the lungs and to other tissues in the body.
Some of the major functions of the cardiovascular system are transporting hormones and fighting off diseases. Other functions include transporting the nutrients and removing the waste from the body. The cardiovascular system can also regulate your body temperature. Some of these functions are not as important as transporting oxygen to the heart and removing the carbon dioxide from the heart.
The cardiovascular system is made up of two circulatory routes, the pulmonary circuit and the systematic circuit. The blood is oxygenated in the lungs during the pulmonary circuit and then the oxygenated blood is circulated through the rest of the body by the systematic circuit.
The two major cardiovascular circuits in the human body is the pulmonary circuit and the systemic circuit. Both of these circuits work together in order to make the body function properly. The major difference between these two circuits is where the blood travels and what areas of the body the blood reaches. The pulmonary circuit carries blood to only the lungs which focuses more on gas exchange. The systemic circuit carries blood to the tissues in the entire body which focuses more on supplying the tissues with oxygen and nutrients. Another interesting fact that separates these two circuits is the blood itself and the process that which it flows. At the beginning of the pulmonary circuit, the blood is deoxygenated. The oxygen poor blood then
