The human body cells need oxygen in order to function and the respiratory system allows this to happen. Consisting of air passages‚ pulmonary vessels‚ the lungs and breathing muscles‚ it supplies fresh oxygen to the blood which can be fed to other parts of the body. The ribs‚ rib muscles and diaphragm all play a part in allowing air into and out of the lungs‚ (oxygen going into the body and carbon dioxide leaving the body). This is known as ventilation. When we breathe in we inhale and when we

of Group Members: Date: Introduction: In this lab‚ you will be examining many characteristics of a rat’s anatomy. Dissections help researchers get a 3-dimensional picture of how the systems of a body work together. Now you’ll have the opportunity to see how the respiratory‚ digestive and circulatory system are arranged spatially. The Classification of the Rat (Rattus norvegicus): Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Mammalia Order: Rodentia

Assessing Blood Pressure Anatomy of the Heart The heart is located in the thoracic cavity between the lungs within the mediastinum. It is a hollow‚ cone-shaped‚ muscular organ about the size of a fist. Functions of the Heart keeps O2-poor blood separate from O2-rich blood; keeps the blood flowing in one direction—blood flows away from and then back to the heart in each circuit; creates blood pressure‚ which moves the blood through the circuits; Regulates the blood supply based on

Energy and Metabolism P4:.2. Explain the role of the respiratory system in energy metabolism by referring to- a) Inhalation and exhalation. b) Gaseous exchange between alveoli and blood. The respiratory system takes oxygen (O2) into the body and eliminates carbon dioxide (CO2). It also enables speech production. Our bodies need energy for movement‚ growth and reproduction. This energy can only be obtained from the food we eat. By the process of respiration‚ chemicals of food are eliminated

Inspiration/ inhalation is the first half of the respiratory cycle where breath is drawn. Several muscles in the respiratory system contribute to the process of inhalation. However‚ the diaphragm and the external and internal intercostals are the primary muscles of inhalation. The diaphragm originates at ribs 7 through 12‚ the xiphoid process‚ and the first 3 lumbar vertebrae. The diaphragm inserts on its’ central tendon which it pulls down and forwards through contraction in order to increase the
