Extract heat and moisture from the air leaving the nasal cavity. Heat and moisten the air entering the nasal cavity. Destroy pathogens entering the nasopharynx Which of the following respiratory structures is more commonly known as the "throat"? =throat The _________________ is also known as the "guardian of the airways".

Respiratory System Study guide: Answer the following‚ submit through the assignments link as an msword document. Shenaira Allen 1. What percent of air is oxygen? The air is 21% oxygen 2. What is the entire process of gas exchange between atmosphere and body cells called? The entire process of exchanging gases between the atmosphere and body cells is called respiration. 3. What is the waste product of cells? The two main waste products of respiration are Water (H2O) and Carbon Dioxide

9.01 Brings oxygenated air to the alveoli. Removes air containing carbon dioxide. Filters‚ warms‚ and humidifies the air. Produces sound (speech). Helps with sense of smell. Assists to regulate the pH within the blood. 9.02 Nose- Nares/Nostrils- Allow entrance for air. Nasal Cavity- Lined with mucous & ciliated epithelium. Air is filtered‚ warmed‚ and humidified. Nasopharynx- Part of the throat serving only as a passageway for air. Pharynx- Throat. 3 Passageways that serve for air

Laboratory report investigating the equine respiratory and cardiovascular systems Introduction The respiratory and cardiovascular systems of the horse work together to transport oxygen around the body and play an essential part in providing the horse with its increased need for oxygen during exercise. They allow the musculoskeletal system to use energy to facilitate motion. The cardiovascular system comprises the heart‚ blood vessels and blood. The heart pumps blood around the body

This essay will explain the function of the respiratory‚ digestive and cardiovascular systems and how they work together to produce nutrients and oxygen to the cells for cellular respiration (energy for the body) The first system in the body is the digestive system. When food enters the mouth the salivary glands secrete saliva which mixes with the food. This makes it easy to chew and swallow. Once the food has been chewed enough the food travels down the oesophagus to the stomach. Once the food

or go back to size‚ rib cage moves down and in diaphragm relaxes. The lungs are the main part of the respiratory system. The respiration system produces energy from taking oxygen and produces carbon dioxide which is takes place in the cells. The oxygen goes to the mitochondria inside the cell where it combines with sugar to create energy and produce carbon dioxide and water. The respiratory system connects to circulatory the system because blood goes to the lungs and to picks up oxygen and releases

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
