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

Curiosity: What is the effect of temperature of saline on cardiac output? HYPOTHESIS: Cardiac output is higher in a hot saline and low in cold saline temperature parameters. Educated Guess Answer: Phenomenally cardiac output is supposed to rise in hot saline conditions and drastically go down in cold saline conditions. Normalising Data Table 2.1: Cardiac output normalised data of frogs in normal‚ hot and cold saline conditions Normal Hot Cold FROG SV(mV/beat) HR(beat/min) Cardiac output(L/min)

different medical careers and came upon respiratory therapy. I have a family friend that works as a respiratory therapist and when I started asking questions I became very intrigued. I signed up to job shadow for a day and instantly fell in love with the work! Being a respiratory therapist ties in my passion of wanting to help people and the challenge‚ I enjoy of constantly learning new things.

Respiratory system: Minute ventilation is the quantity of oxygen which is taken in by your lungs per minute. When we exercise there is a higher oxygen intake per minute due to a higher breathing rate‚ we will also need more oxygenated blood cells to go round to the muscles in use to help try and prevent muscular injuries. The reason why when minute ventilation increases is positive to an athlete is because there is a higher intake of oxygen and nutrients needed. This will mean that the athlete

Respiratory Function Jeremiah Schmidt - 17456597 ------------------------------------------------- INTRODUCTION The aim of practical 3 under the respiratory control subsection was to investigate the effects that hyperventilation and rebreathing have on ventilation rate and breaking point and to observe the effect of carbon dioxide (CO2) on water pH (School of Science and Health 2012). The results from respiration rate and breaking point were then compared to the different sexes and further

Respiratory System: Study Guide The respiratory system provides for exchange of oxygen and carbon dioxide of the body. - In terrestrial vertebrae’s‚ the respiratory system includes 3 steps: 1. Breathing: Inspiration (inhaling oxygen) and Expiration (exhaling carbon dioxide) 2. External exchange- Gas exchange between the AIR and BLOOD in lungs. Blood then transfers oxygen to the tissue cells. 3. Internal exchange- Gas exchange between the BLOOD & TISSUE FLUID and between the CELLS & TISSUE FLUID

RESPIRATORY SYSTEM Respiratory System Organs and Its Functions Introduction to the respiratory system organs: The respiratory system is the system of the human body by which it produces energy needed for life processes. This energy is produced by the breaking down of glucose molecules in all living cells of the human body. Introduction to the respiratory system organs: In simple terms‚ Oxygen taken in to the body through air breathed in is transported to all parts of the body‚ and it
