Answers 1a) On graph paper 1b) At molecular level‚ Haemoglobin is a protein made of four subunits bound together. Each of the subunits consists of a molecular group known as ‘heme’ and a polypeptide attached to the ‘heme’. The ‘heme’ group contains one atom of iron (Fe²+) and it is this iron that the oxygen molecule combines itself to. As there are four of the iron molecules in the haemoglobin this shows that a maximum of four oxygen molecules can be carried by the haemoglobin at anytime. For simplicity

Respiratory system: The respiratory system is a combination of the Circulatory and Pulmonary systems feeding oxygen and nutrients to cells all around the body. These systems allow oxygen to enter the body‚ and be circulated around the body at a varying rate. These two systems work in conjunction with each other and have various rates of operation that are usually in as close a correlation as possible. Circulatory System: The circulatory system’s primary responsibility is to circulate oxygenated

The respiratory system The respiratory system is responsible for providing oxygen and removing carbon dioxide‚ heat and water vapours. All living creatures require oxygen and give off carbon dioxide. Oxygen is required for every cell in your body to function. Structure of the respiratory system: Normally air is taken in through your nose however sometimes it is taken in through your mouth and passes through a series of airways to reach the lungs. This series of airways is known as the respiratory

oxygen and respiratory disease. Respiratory disease is the term used for defining diseases like chronic obstructive pulmonary disease (COPD)‚ emphysema and asthma. Common signs and symptoms of respiratory disease are coughing‚ wheezing‚ dyspnoea and production of abnormal secretions like sputum and haemoptysis (Jenkins et al 2008). Respiratory disease accounted for 8.4% of the registered deaths in Australia in 2007. There was an estimated 6.6% increase in deaths caused by respiratory disease from

Anatomy of the Respiratory System Nose and Nasal Cavity The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The nose is a structure of the face made of cartilage‚ bone‚ muscle‚ and skin that supports and protects the anterior portion of the nasal cavity. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function
