The systemic route is the major part of the circulatory system. The systemic route is responsible for transporting blood to all of the tissues located in your body except for the lungs and the heart. Oxygenated blood from the aorta travels through the arteries, veins, and capillaries. The arteries carry the oxygenated blood to the tissues and the veins carry the deoxygenated blood back to the heart.
Another route of circulation is the fetal route of circulation. The fetal circulation is blood from the placenta that is helping the baby to live. The placenta accepts deoxygenated blood from the mother through blood vessels from the umbilical cord. According to heart.org, “Blood coming back from the fetus’s body also enters the right atrium,
but the fetus is able to send this blue blood from the right atrium to the right ventricle (the chamber that normally pumps blood to the lungs).”
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
Pulmonary arteries carry blood from the heart to the lungs where the blood picks up oxygen. The oxygen rich blood is then returned to the heart via the pulmonary veins. Systemic arteries deliver blood to the rest of the body. The aorta is the main systemic artery and the largest artery of the body. It originates from the heart and branches out into smaller arteries which supply blood to the head region brachiocephalic artery, the heart itself coronary arteries, and the lower regions of the body.
The cardiovascular system is divided into two systems a pulmonary and a systemic. Pulmonary division- blood flows from the heart to alveolar capillaries and back to the heart. Systemic division- blood flows from heart to every capillary “except alveolar” and back to heart.
The Structure and Functions of the Arteries Arteries are blood vessels that convey blood from the heart to the tissues of the body. The arteries expand and then constrict with each beat of the heart, a rhythmic movement that may be felt as the pulse. Arteries are usually named from the part of the body that they are found, for example; brachial artery found in the arms, metacarpal artery found in the wrist; or from the organ which they supply as the hepatic artery supplies the liver, pulmonary artery brings deoxygenated blood the lungs. The facial artery is the branch of the external carotid artery that passes up over the lower jaw and supplies the superficial portion of the face; the haemorrhoidal arteries are three vessels that supply the lower end of the rectum; the intercostal arteries are the arteries that supply the space between the ribs; the lingual artery is the branch of the external carotid artery that supplies the tongue. The structure of the artery enables it to perform its function more efficiently.
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
and support, allows us to manipulate our surroundings and - due to its high metabolic activity - produces heat.” (study.com-Dec 2014)
The pattern of blood flow starts in the left atrium to right atrium, then into the left ventricle and right ventricle. During its course, blood flows through the mitral and tricuspid valves. Simultaneously, the right atrium is granted blood from the veins through the superior and inferior vena cava. The job of the superior vena cava is to transport de-oxygenated blood to the right atrium. When your heart beats, the first beat represents the AV valves closing to prevent the backflow of blood into the atrium.
Oxygen is going from the capillaries to the tissues, and carbon dioxide from. tissues taken up into the capillaries. Arteries have to be strong as well as flexible because of the pressure of the blood being pumped. through the venous system. Veins get bigger when they get closer to the heart of the world.
The Respiratory System 1. Define respiration. Respiration is the process of converting glucose to energy, which goes to every cell in the body. 2. Describe the organs of external respiration.
the aortic valve, between the left ventricle and the aorta. heart_chambers.jpg Each valve has a set of "flaps" (also called leaflets or cusps). The mitral valve normally has two flaps; the others have three flaps. Dark bluish blood, low in oxygen, flows back to the heart after circulating through the body. It returns to the heart through veins and enters the right atrium.
In Harvey’s conception, the heart drives the mechanics of blood circulation and not the liver. Transfer of blood from arteries to veins in the lung and periphery may occur through direct connections or anastomoses or through porosities in the flesh (the latter mechanism being favored by
Arteries carry oxygen-rich blood from the heart through the body while veins carry oxygen-poor blood back to the heart. The heart pumps some blood to the lungs while the rest goes to the other organs in the body. Blood enters the heart through a vein and collects in the atrium. The atrium then contracts pusing the blood into a ventricle. Next, the ventricle contracts and all the blood is forced out through an artery and into the lungs or rest of the body.
The chamber of fish heart is not separated by septum. Arteries carry blood to the heart while veins carry blood away from the heart. The fish heart only has one atrium and one ventricle. The oxygen-depleted blood from the body enters the atrium, and followed by the ventricle, and is then pumped out to the gills where the blood is oxygenated, and then it continues to circulate throughout the rest of the body. The human circulatory system is double circulation which includes the heart, veins, arteries and capillaries. The human heart chamber is separated by septum. The right part of the heart receives low oxygen blood returning back from the body. The right atrium receives this deoxygenated blood and then the right ventricle to be pumped to the lungs where the blood will be oxygenated. The oxygenated blood from the lungs is then enters the left ventricle through the left atrium and followed by pumping out into the larger body circulation (Environmental Science Investigation, n.d.). The blood transports oxygen and nutrients to the cells and removes waste products (OSU Klamath Basin Research and Extension Center, 2009). Both of them are closed circulation and heart acted as pumping organ to circulate the blood throughout the
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
