Image: Human Respiratory System (Jain, 2016) The Cardiovascular System – Anatomy The cardiovascular system is comprised of the heart, vessels and blood. The cardiovascular system includes the heart and blood vessels and performs the function of pumping and carrying blood to the rest of the body. Thank you for signing up to Live Science. Drag and drop the text labels onto the boxes next to the heart diagram. The largest arteries of the body contain a high percentage of elastic tissue that allows them to stretch and accommodate the pressure of the heart. Also known as thrombocytes, platelets are small cell fragments responsible for the clotting of blood and the formation of scabs. The aorta carries oxygenated blood from the heart to organs and tissues. Arteries face high levels of blood pressure as they carry blood being pushed from the heart under great force. The high surface area to volume ratio of erythrocytes allows oxygen to be easily transferred into the cell in the lungs and out of the cell in the capillaries of the systemic tissues. cardiorespiratory system? Blood vessels are often named after either the region of the body through which they carry blood or for nearby structures. Future US, Inc. 11 West 42nd Street, 15th Floor, We hate spam as much as you do. Blood vessels can also affect blood pressure. If you want to redo an answer, click on the box and the answer will go back to the top so you can move it to another box. Veins rely on gravity, inertia, and the force of skeletal muscle contractions to help push blood back to the heart. The heart is a four-chambered “double pump,” where each side (left and right) operates as a separate pump. Ð Transport O 2 to tissues and removal of waste Ð Transport of nutrients to tissues Ð Regulation of body temperature. The heart is considered to be the powerhouse of the circulatory system, its function is to pump blood around the body. The liver removes toxins, stores sugars, and processes the products of digestion before they reach the other body tissues. Its main function is to transport nutrients to cells and wastes from cells (Figure 2.1.3.3 “Cardiovascular Transportation of Nutrients”). Greater contractile force and heart rate lead to an increase in blood pressure. It is comprised of three parts: the pulmonary circulation, coronary circulation, and systemic circulation. Once active, platelets change into a spiny ball shape and become very sticky in order to latch on to damaged tissues. What is a Circulatory System Diagram. The left side of the heart receives oxygenated blood from the lungs and pumps it through the systemic arteries to the tissues of the body. Please refresh the page and try again. The quiz below is all about the system and all we learned about it. Each of the quizzes includes 15 multiple-choice style questions. One of the biggest challenges to homeostatsis is exercise through an increase in the demand for oxygen. Respiratory System Diagram. The diaphragm is a dome-shaped muscle that curves upwards towards the lungs. The subclavian artery runs into the axillary region where it becomes known as the axillary artery. Neutrophils contain digestive enzymes that neutralize bacteria that invade the body. The proteins within plasma include antibodies and albumins. Cardiovascular system diagrams, quizzes and free worksheets. Responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the body’s hardest-working organ — the heart, which is only about the size of a closed fist. Since there is a limited supply of blood, and not all tissues have the same energy and oxygen requirements, the precapillary sphincters reduce blood flow to inactive tissues and allow free flow into active tissues. Blood carried by arteries is usually highly oxygenated, having just left the lungs on its way to the body’s tissues. Venules pick up blood from many capillaries and deposit it into larger veins for transport back to the heart.

Comprised of the heart and circulatory system, the cardiovascular system transports nutrients to and removes gaseous waste from the cells of the body. The heart is a muscular organ with four chambers. The systemic circulation is a major portion of the circulatory system. In this interactive, you can label parts of the human heart. Blood is propelled by the heart, with arteries, capillaries, and veins serving as the major vessels of the system. Image: Human Respiratory System (Jain, 2016) The Cardiovascular System – Anatomy The cardiovascular system is comprised of the heart, vessels and blood. TCE Sport science The Cardiorespiratory system The Cardiorespiratory System: The major anatomical structures of the cardiorespiratory system include the heart and lungs. Many serious conditions and diseases can cause our cardiovascular system to stop working properly. The regulation of blood flow also affects blood pressure, as smaller arteries give blood less area to flow through and therefore increases the pressure of the blood on arterial walls. Similarly, contraction of the external intercostal muscles moves the ribs upwards and outwards. Lymphocytes include T cells and natural killer cells that fight off viral infections and B cells that produce antibodies against infections by pathogens. Start studying NASM Chapter 3, The Cardiorespiratory System. If you get a question right the next one will appear automatically, but if … A heavy exercise session can increase demand for oxygen by up to 15 to 25 times above the resting level. In fact, the heart is a double pump. There are 2 primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. Human cardiovascular system, organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes. As skeletal muscles in the body contract, they squeeze nearby veins and push blood through valves closer to the heart. Many different substances can be found dissolved in the plasma, including glucose, oxygen, carbon dioxide, electrolytes, nutrients, and cellular waste products. The body's circulatory system includes the cardiovascular and lymphatic systems; the quizzes below focus on the cardiovascular system. They face much lower blood pressures than arteries due to their greater number, decreased blood volume, and distance from the direct pressure of the heart. Hemostasis, or the clotting of blood and formation of scabs, is managed by the platelets of the blood. Veins carry oxygen-poor blood back to the heart. The cardiac cycle provides the "muscle" needed to pump blood throughout the body. Erythrocytes transport oxygen in the blood through the red pigment hemoglobin. Not only do animals need a way to get more oxygen into the cells, but they al… All blood vessels contain a hollow area called the lumen through which blood is able to flow. The superior vena cava carries oxygen-poor blood into the heart. On black background. The respiratory system, which includes air passages, pulmonary vessels, the lungs, and breathing muscles, aids the body in the exchange of gases … The shape of erythrocytes is biconcave—disks with a concave curve on both sides of the disk so that the center of an erythrocyte is its thinnest part. Copyright © Innerbody Research 1999 - 2020. The left atrium and left ventricle of the heart are the pumping chambers for the systemic circulation loop. One of the biggest challenges to homeostatsis is exercise through an increase in the demand for oxygen. Antibodies are part of the immune system and bind to antigens on the surface of pathogens that infect the body. Platelets normally remain inactive in the blood until they reach damaged tissue or leak out of the blood vessels through a wound. Which cell is flexible and elastic so it can squeeze through the capillaries? Blood is propelled by the heart, with arteries, capillaries, and veins serving as the major vessels of the system. 29 August 2013. The primary function of the respiratory system is to allow oxygen (O 2) to move from the air into the venous blood and carbon dioxide (CO 2) to move out.Oxygen and carbon dioxide pass between air and blood by simple diffusion across the alveolar-capillary membrane. The right side of the heart receives deoxygenated blood from the systemic veins and pumps it to the lungs for oxygenation. Which part of the cardio-respiratory system has a small diameter which helps with diffusion of nutrients and gasses? Platelets next release chemical clotting factors and begin to produce the protein fibrin to act as structure for the blood clot. The cardio-respiratory system works together to get oxygen to the working muscles and remove carbon dioxide from the body. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Superior Vena Cava & Inferior Vena Cava. The vessels are vital in transporting blood, nutrients, waste, oxygen and hormones throughout the body. The vessels are vital in transporting blood, nutrients, waste, oxygen and hormones throughout the body. PIXOLOGICSTUDIO/Science Photo Library/Getty Images Heart . Find out all about the blood, lungs and blood vessels that make up the circulatory system. Each heartbeat results in the simultaneous pumping of both sides of the heart, making the heart a very efficient pump. When the muscle relaxes, the valve traps the blood until another contraction pushes the blood closer to the heart. Please deactivate your ad blocker in order to see our subscription offer. Located just behind and slightly left of the breastbone, it pumps blood through the network of arteries and veins called the cardiovas- cular system. A heavy exercise session can increase demand for oxygen by up to 15 to 25 times above the resting level. Which cell contains haemoglobin? Thicker, more viscous blood from clotting disorders can also raise blood pressure. Abstract. Circulatory system diagrams are visual representations of the circulatory system, also referred to as the cardiovascular system. The cardiovascular system moves blood throughout the body, and the lymphatic system moves lymph, which is a clear fluid thats similar to the plasma in blood. Platelets form in the red bone marrow from large megakaryocyte cells that periodically rupture and release thousands of pieces of membrane that become the platelets. Explore {{searchView.params.phrase}} by color family The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The left and right coronary arteries branch off from the aorta and provide blood to the left and right sides of the heart. White blood cells, also known as leukocytes, make up a very small percentage of the total number of cells in the bloodstream, but have important functions in the body’s immune system.
