Goals

Identifying and understanding the process of smelling
Identifying the physiological parts involved in smelling.
Animals have five different senses that enable them to function. The sense include, smelling, hearing, seeing, feeling and tasting. All the five senses are important in the manner in which they are of use to animals. Each of the five different senses has a different organ through which it utilizes to carry out its function. Smelling is carried out through the anatomical part known as the nose. In humans, the nose appears as a protrusion form the face (the size varies among different individuals). Some animals such as dogs have a stronger sense of smell in comparison to other animals such as humans. The nose has features that ensure its smelling function is effectively executed. The nose cleans, warms and moistens air before it is transported to other breathing organs such as the lungs. Transport of fresh air that contains oxygen is very important and important for life to be sustained (Alters 93).
If foul and toxic gases are smelled and breathed into the human body, they might lead to collapse of normal body processes.The sense of smell organ; nose, closely works in close conjunction with other body organs such as the eyes. However, even individuals without the sense of seeing also have effective senses of smelling. In the past, it was thought that blind individuals have better senses for smelling. However, recent studies indicate that they have similar smelling capabilities as individuals with normal eyesight. Smells that are produced by different substances have different vapors which they produce, generate and it is then detected by the receptors in the nose. The nose has membranes that are lined with receptors which are linked to the olfactory nerve.
The nose has small hairs that filter the air that is breathed in before it is inhaled to other body parts such as the lungs. The airs ensure that no physical obstructions enter through the nose. The lungs need the air that is inhaled to be as clear as possible. After the air moves through the nose, it...
