    The human body is an amazing machine, we have cells, tissues, organs and organ system that come together to create the human race. Each system plays a key role in our bodies mechanism. Without each systems our bodies would not function properly, but what happens when one of these system fails? The Cardiovascular system components are blood, blood vessels and the heart. The hearts function is to pump blood to all the major organs and tissues (Circulatory). It’s also important to be aware of the derivation that our bodies may encounter, for example a stroke. In this passage I discuss different types of strokes, what are the signs and symptoms and after care for this disorder of the cardiovascular system.

    both these sysmtems work with one another to ensure that organs tissues in the body are supplied with an adequate amount of oxygen, and that carbon dioxide can be removed. firstly through the respiratory system, oxygen is inhaled through the nose and mouth, the oxygen is will travel down the trachea, the rachea divides into the bronchial tubes which enters the lungs. the bronchi divides into smaller branches known as the bronchioles, which have tiny air sacs called alveoli on the end. The alveoli is surrounded by thin blood capillaries, the wall of the capillaries is a single layer of cells. These thin walls allow gas exhange to take place. Oxygen will be diffused in the capillaries and will go into the red blood cells, where it will then be transported back to the heart. carbon dioxide will be diffused though the capillary walls into the alveoli, in an opposite path than oxygen. carbon dixoxide will be released in the lungs and through exhalation the carbon dioxide will be removed.The right atrium of the heart will supplied with de-oxygenated blood by the superior and inverior vena cava. The right atrium will pump the de-oxygenatd blood via the atrioventricualr valve until it reaches the right ventricle. the right ventricle will pump the de-oxygenated blood via the pulmonary semi-lunar valve, which will carry the blood pass through the pulmonary arteries unti it reaches the lungs. these veins from the lungs will carry oxygenated blood to the right atrium. the right atrium will now pump this fresh oxygenated blood past the aventricular valve so it can enter the left ventricle. the left ventricle the thickest out of the four chambers and will pump, so that oxygenated blood is supplied to all the organ tissues in the

  • The Cardiac Cycle

    Elaborate: The cardiac cycle of the heart is divided into diastole and systole stages. Diastole refers to the period of relaxation experienced by the atria and ventricles. Systole is the contraction of the atria and ventricles. 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

    I start my journey in bone marrow. Have you ever seen how flexible bone marrow is!?! It’s really exciting. I form from hemocytoblast which takes about 2 days. The body makes about two million red blood cells every second. So there’s a lot of me to go around. I finally get to leave and make my way through the veins capillaries along with my buddy plasma. We take up most of the room since there’s so much to go around, but on my behalf those guys aren’t that big to begin with. Eventually I go to what I like to call the big brother of the vein capillaries the arteries. Those are so much bigger but they do more work and they are stronger the capillaries are nowhere near as strong! I eventually make my way to your heart! If you close your fist, that’s about the average size of your heart. The heart pumps about 2,000 gallons (7,571 liters) of me a day through its chambers, no you don’t have the much of me in your body but it pumps me over and over. Y­our heart receives me already oxygenated in the same way your brain, foot and the rest of your body do: through an artery. Now although the h...

    The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...

    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

  • Circulatory System

    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.

    ...gs compared to that of the surrounding blood. After oxygen molecules moves into the blood, they are bound to the red blood cells and are then transported through the body. Blood containing oxygen travels from the lungs into the chambers of the heart. When it reaches the heart, it is pumped around the rest of the body. The oxygenated blood travels through a number of vessels, allowing the red blood cells to come into contact with other cells in the body. The red blood cells further take the unwanted carbon dioxide through an opposite system of vessels into the heart. Upon reaching the heart, they are then pumped to the lungs, and come into contact with the alveoli. Hence, the respiratory system and the circulatory system interact with each other when the red blood cells discharge carbon dioxide into the lungs as waste product. Exhalation marks the end of the cycle.

  • Essay On The Respiratory System And The Circulatory System

    930 Words  | 2 Pages

    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
