This will be so because exercising will cause more oxygen intake and will lead to breathing out more carbon dioxide. Materials List: • Bromothymol Blue solution • Beaker or flask • 10mLgraduated cylinder • Water • Pipette • Straws • Stop watch (phone). Procedure: 1. The flask was filled with 100mL of water. 10mL of Bromothymol Blue was added to the flask.
To fix this issue, the chemical potassium hydroxide will be added that will selectively take out C02. Potassium hydroxide will chemically react with carbon dioxide by the following equation: C02 + 2 KOH -> K2CO3+ H20 A microrespirometer is the system used to measure cellular respiration. As long as the volume and temperature in the microrespirometer does not change, the pressure changes in the microrespirometer are directly relative to a change in the amount of gas in the microrespirometer. Therefore, by comparing separate microrespirometers, each with different test subjects within, we can observe the different rates at which cellular respiration occurs. Hypothesis In this experiment, the rate of cellular respiration in the germinating peas will be higher than that of the glass beads; non-germinating peas; and seeds mixed with glass beads.
It releases around 5% of the energy released by aerobic respiration, per molecule of glucose. The waste product is lactic acid rather than carbon dioxide and water: glucose → lactic acid (+ little energy) [2] The heart rate during exercise is an indicator of intensity, or in other words how hard you are working. As you get fitter, your heart rate decreases for any given exercise workload. Aerobic exercise has the aim of improving the body's consumption of oxygen whereas the aim of anaerobic exercise is to build power, strength and muscle. The muscles are exercised at high intensity for short durations [3].
(5 marks) 5 organs inferior the clavicles are: Lungs- these help us to breathe but extracting carbon dioxide through the walls of the lungs. Heart- this pumps clean blood around our body to help us survive. Kidneys- the kidneys flush out all the bad nutrients from our body and produces urine. Liver- this is where bile is produced and leaves through here. Stomach- It continues the digestion
2) Coronary artery disease is usually caused by a build-up of fatty deposits on the walls of the coronary arteries. The fatty deposits, called atheroma, are made up of cholesterol and other waste substances. The build-up of atheroma on the walls of the coronary arteries makes the arteries narrower and restricts the flow of blood to the heart. Cholesterol is a fat made by the liver from the saturated fat that we eat. Cholesterol is essential for healthy cells, but if there is too much in the blood it can lead to CAD.
| | | Lesson 6 - The Cardio-Respiratory System DefinitionsThe cardio-respiratory system consists of the cardio vascular system (heart and blood vessels) together with respiratory system (lungs and air ways). These systems work to transport oxygen to the muscles and organs of the body and remove waste products including carbon dioxide. The HeartThe heart is a double pump. "Oxygen-poor" blood enters the heart from the vena cava to the right atrium, and flows down to the right ventricle. The first pump pumps "oxygen poor" blood to the lungs from the right ventricle of the heart via the pulmonary artery where it returns as "oxygen rich blood" via the pulmonary vein to the left atrium.
Water keeps the tissues in the eyes, mouth, and nose moist, it lubricates joints, protects organs, and is the primary constituent of blood. In adults, water accounts for about 60% of body weight (Grosvenor & Smolin, 2012). It is no wonder that when the body uses more water than an individual is consuming the body becomes dehydrated. Dehydration is a state that occurs when not enough water is present to meet the body’s
1a. At 8 am, Ben’s blood pressure plummets. List the two body parts that respond to the problem with blood pressure according to the tutorial in the order that they respond and explain what each organ system does to correct this problem. The first to respond is Ben’s nervous system, which senses a change in Ben’s blood pressure due to his fast movement out of the chair. This sends a signal to the heart that Ben’s blood pressure is low, and the heart begins to pump at an increased rate to correct the problem.
Lipid break down, your body can breakdown triglycerides as a source of energy. If your body requires energy and glucose isn’t available your adipose tissue begins to breakdown fatty acids into molecules that your cells can use as energy. Lipid breakdown proves important weight loss. Your body uses energy from stored fat to maintain your tissue. So if you lose fatty tissue you lose weight.
You have other stress, such as family conflicts or school or dating problems. You may have experienced the dawn phenomenon (a surge of hormones that the body produces daily around 4:00 a.m. to 5:00 a.m.). What are the Symptoms of Hyperglycemia? High blood glucose High levels of sugar in the urine Frequent urination Increased thirst How Do I Treat Hyperglycemia? You can often lower your blood glucose level by exercising.
