The respiratory system of the horse is well adapted to athletic exercise‚ with unrestricted upper airway diameters‚ and a large lung capacity afforded by 18 ribs. These combine to enable air intakes of up to 1800 litres per minute in a galloping horse. Volumes of up to 300 litres of blood are pumped at high pressure through small lung capillaries surrounding 10 million air sacs to take up and deliver over 70 litres of oxygen per minute to the working muscles at the gallop. As a result‚ any restriction

between atmospheric pressure‚ intrapulmonary pressure‚ and intrapleural pressure.. Atmospheric pressure is the pressure exerted on us on the earth due to the weight of air molecules. Humans are not overwhelmed with this because of Intrapulmonary pressure‚ the pressure within our lungs. Intrapulmonary pressure causes our lungs to stay slightly inflated even after we exhale. Intrapleural pressure is the pressure on our pleura

chosen for this wonderful journey through the digestive system. I personally have never been in this journey but I’ve heard of this long process by my other peers. The fiber‚ potassium‚ and vitamins are all ready to be soaked up into this lucky person’s body for energy. My journey begins in the oral cavity. As I’m being chewed the teeth the teeth tear me apart into smaller pieces and the salivary glands produce saliva to break me down even further to make it easier for my journey down the pharynx. As

TUTORIAL 2: RESPIRATORY SYSTEM OBJECTIVE QUESTION 1) High-flying birds are able to obtain enough oxygen even when the air is very thin because A) they have more efficient lungs than other vertebrates. B) they have reduced amounts of hemoglobin in their blood. C) their mitochondria are more efficient than those of other vertebrates. D) their heart can increase or decrease in size as altitude changes. E) they are able to store oxygen in oxygen chambers within muscle cells. 2) If you were to move from

Phoenix Material Roderick Tabigne Respiratory System Lab – Week Six Introduction The respiratory system consists of the upper respiratory tract (the nasal cavity‚ pharynx‚ larynx‚ trachea‚ and bronchi) and the lower respiratory tract (the lungs). As you learn about the various diseases that affect the respiratory system‚ it is important for you to understand the structures that can be affected by disease. Complete this lab to become familiar with a healthy system and to identify diseases related to

REDUCTION Oxygen makes up only about 20% of the air‚ yet is the essential component for so many reactions. Without it fuels would not burn‚ iron would not rust and we would be unable to obtain energy from our food molecules through respiration. Indeed animal life on the planet did not evolve until a certain concentration of oxygen had built up in the atmosphere over 600 million years ago. The term oxidation has been in use for a long time to describe these and other reactions where oxygen is added

he Respiratory System Fig 4. Horse’s respiratory system The functions of the respiratory system are to provide the body with oxygen‚ to remove carbon dioxide from the body‚ to control temperature (breathing out warm air and breathing in cool air)‚ to eliminate water‚ to communicate (Voice production) and sensory input (Smell/ touch- nose hairs). The respiratory system consists of the nostrils‚ pharynx‚ larynx‚ Nostrils The nostrils expand to allow air to enter the respiratory system‚ hairs within

Air enters the nose by passing through the external nares or nostrils. The mucosa lining the nasal cavity‚ called the respiratory mucosa‚ warms the air as it flows pa Respiratory physiology The major function of the respiratory system is to supply the body with oxygen and to dispose of carbon dioxide. To do this‚ at least four distinct events‚ collectively called respiration‚ must occur: 1. Pulmonary ventilation Air must move into and out of the lungs so that the gases in
