Physiology of the Respiratory Systeme UNIT OUTLINE Mechanics of Breathin Activity 1: Analyzing the and Pulmonary Ventilatio Activity 2: Measuring Re Volumes in a Human Sub Activity 3: Determining Volumes and Capacitie Following Exercise Control of Breathin Activity 4: Investigat of Breathing PhysioEX Exercise | n the previous unit we explored the anatomy of the respiratory system. Here we Syst will examine the various functions of the respiratory system. First we consider the various processes involved in the mechanics of breathing: next we explore the various quantities of air that flow into or out of the lungs during a given breath.PEx Activity 2: Co Finally, we briefly investigate the processes by which the body controls breathing,PEx Activity 3: Eff Volumes and Calcul Intrapleural Pressu THINK ABOUT IT Describe the role of the organ system listed in the maintenance of homeostasis for each of the following respiratory events: The cardiovascular system in the exchange of oxygen and carbon dioxide in the lungs The muscular system in inhalation and exhalation : The cardiovascular system in the transport of gases throughout the body The lymphatic system in the exchange of gases between the blood and cells of the : tissues Ace your Go to There yo . Pract inclu PhysExplanation / Answer
The cardiovascular system in the exchange of oxygen and carbon dioxide in the lungs.
Perfusion is the process by which the cardiovascular system pumps blood throughout the lungs. Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body. Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava, and the inferior vena cava. This blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide. Oxygen passes quickly through the layers of cells lining the alveoli and the surrounding capillaries (air-blood barrier) into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
The muscular system in inhalation and exhalation.
the inspiratory muscles expand the thoracic cavity and help in inhalation, while those that compress the thoracic cavity are called expiratory muscles and they induce exhalation. The external intercostals and the diaphragm contract causing the vertical dimension of the thoracic cage to increase which draws air into the lungs. the accessory muscle of inspiration are sternocleidomastoid and scalenus group of muscles. expiration ion is passive process which folows inspiration.The internal intercostals and abdominal muscles pull the ribs down causing the cage to compress which pushes out the air from the lungs after normal exhalation.
The cardiovascular system in the transport of gases throughout the body.
Oxygenated blood from the lungs flows back to the heart via the pulmonary veins and is then pumped to the rest of the body from the left ventricle via the aorta and its branches. Capillary beds of all the tissue is where the exchange occurs.
The lymphatic system in the exchange of gases between the blood and cells of the tissues.
Blood carries oxygen, nutrients etc. to the cells in the body. the exchange of these nutrients and gases happens between the blood and the cells. This occurs in the lymph. it collects the excess fluid that leaks out of blood. filters the fluid for the waste products and transports the cleansed fluid to the circulatory system.
