Most of blood is made of the yellow-colored liquid _______. _______ blood cells are part of the immune system and fight off infections. Blood must reach every single cell in the body. In order to do this, blood flows through the _______, which are small blood vessels, often only 1 cell thick. Most _______ carry oxygen-rich blood away from the heart and are coded red in anatomy diagrams. Blue-colored blood vessels indicate low-oxygen blood and are called _______. The _______ is the main artery out of the heart, taking freshly-oxygenated blood from the left ventricle to deliver to the rest of the body. The right ventricle pumps blood to the lungs through the _______; this is typically colored blue even though it carries blood away from the heart. _______ is a waste gas that is carried by blood back to the lungs. Respond to the following based on your reading. Write out the process of blood flowing through the heart. Begin with low-oxygen blood returning to the heart from the body. Your response should include the terms: pulmonary artery, aorta, pulmonary vein, superior vena cava, inferior vena cava, left atrium, right atrium, left ventricle, right ventricle, mitral valve, tricuspid valve. Fill in the blank. 1___platelets___ help blood clot following wounds, so that wounds stop bleeding. 2Most of blood is made of the yellow-colored liquid __plasma_____. 3______white_ blood cells are part of the immune system and fight off infections. 4Blood must reach every single cell in the body. In order to do this, blood flows through the ____capillaries___, which are small blood vessels, often only 1 cell thick. 5Most __arteries_____ carry oxygen-rich blood away from the heart and are coded red in anatomy diagrams. 6Blue-colored blood vessels indicate low-oxygen blood and are called ___veins____. 7The _______ is the main artery out of the heart, taking freshly-oxygenated blood from the left ventricle to deliver to the rest of the body. 8The right ventricle pumps blood to the lungs through the pulmonary artery__; this is typically colored blue even though it carries blood away from the heart. 9____carbon dioxide___ is a waste gas that is carried by blood back to the lungs. Respond to the following based on your reading. 10Write out the process of blood flowing through the heart. Begin with low-oxygen blood returning to the heart from the body. Your response should include the terms: pulmonary artery, aorta, pulmonary vein, superior vena cava, inferior vena cava, left atrium, right atrium, left ventricle, right ventricle, mitral valve, tricuspid valve. Blood flows through the heart in a certain order starting from the entry of deoxygenated blood into the right atrium Low-oxygen blood returns to the heart from the body via the superior vena cava and the inferior vena cava. This blood enters the right atrium. The blood flows through the tricuspid valve into the right ventricle. The right ventricle pumps the blood through the pulmonary artery to the lungs for oxygenation. In the lungs, the blood picks up oxygen and releases carbon dioxide, becoming oxygen-rich. The oxygen-rich blood returns to the heart via the pulmonary vein and enters the left atrium. The blood then flows through the mitral valve into the left ventricle. The left ventricle pumps the oxygen-rich blood into the aorta, which carries it to the rest of the body. This cycle enables constant delivery of oxygen-rich blood throughout the body The correct answer is not displayed for Written Response type questions. Hide question 1 feedback Feedback Platelets plasma White capillaries arteries veins aorta pulmonary artery Carbon dioxide The blood returns to the right atrium through the superior vena cava and inferior vena cava and is transferred to the right ventricle through the tricuspid valve. The right ventricle pumps the low-oxygen blood through the pulmonary artery to the lungs. Once the blood has been oxygenated in the lungs, it goes to the left atrium through the pulmonary vein. The left atrium sends the blood through the mitral valve to the left ventricle, which then pumps the blood out to the body through the aorta. Question 2 Exercise Exercise Match the following respiratory conditions to their descriptions and symptoms. 1. Emphysema a. A condition in which an attack can trigger constriction of airways 2. Pneumonia b. The inflammation of bronchioles in the lungs 3. Bronchitis c. The buildup of fluid in the alveoli of the lungs 4. Asthma d. A condition often caused by smoking, featuring damaged alveoli Fill in the blank. _______ are the small sacs that are the site of gas exchange in the lungs. In addition to being an airway, the _______ is the location of the human vocal cords. Cilia in cells along the trachea and nasal passages secrete _______ which traps dirt and particles from the air. Air is only approximately 21% oxygen. The majority of air is ______. The medulla oblongata controls the contraction and relaxation of the _______, causing the lungs to inflate and deflate during breathing. Explain the process of breathing. Begin with inhalation and describe the route that the air takes to the lungs, and what happens when the air reaches the lungs. Include in your description the terms: mouth, nose, pharynx, larynx, trachea, bronchi, lungs, alveoli, carbon dioxide, oxygen, and capillaries. 1-d 2 c 3 b 4 a alveoli _______ are the small sacs that are the site of gas exchange in the lungs. In addition to being an airway, the larynx__ is the location of the human vocal cords. Cilia in cells along the trachea and nasal passages secrete mucus___ which traps dirt and particles from the air. Air is only approximately 21% oxygen. The majority of air is _nitrogen_____. The medulla oblongata controls the contraction and relaxation of the _diaphragm______, causing the lungs to inflate and deflate during breathing. Explain the process of breathing. Begin with inhalation and describe the route that the air takes to the lungs, and what happens when the air reaches the lungs. Include in your description the terms: mouth, nose, pharynx, larynx, trachea, bronchi, lungs, alveoli, carbon dioxide, oxygen, and capillaries. The breathing starts with the mouth and nose. An air flows to the body through the mouth and nose and next goes to the pharynx and larynx. After that it goes down the trachea through the bronchi into the lungs. In the lungs the alveoli perform the gas exchange where carbon dioxide diffuses into the lungs for exhalation. It diffuses through the capillaries and is beingpumped throughout the body. The correct answer is not displayed for Written Response type questions. Hide question 2 feedback Feedback D C B A Alveoli larynx mucus nitrogen diaphragm Air enters the body through the mouth or nose and passes through the pharynx and larynx. Then it travels down the trachea and branches through the bronchi into the two lungs. In the lungs, small alveoli are the site of gas exchange where carbon dioxide diffuses into the lungs for exhalation, while oxygen from the air diffuses into the capillaries surrounding the alveoli to be pumped throughout the body.
