Respiratory system

PRINCIPAL FUNCTION

FUNCTION:

The main function of respiratory system is to take oxigen to give it to the blood and distribute throughout the body.

MAIN PARTS:

• Nose:The two openings in the nose care called nostrils, or napes. They lead to two nasal cavities that are separated by the septum, a wall of cartilage. Inside the face is an intricate system of canals and pockets of air called sinus cavities. Sinus cavities span all the way to the back of the skull, right above the oral cavity, within the cheekbones and between the eyes and brows. All of these areas are responsible, at least in part, for breathing, smelling, tasting and immune system defense.

• Lungs:The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product. We each have two lungs, a left lung and a right lung. These are divided up into ‘lobes’, or big sections of tissue separated by ‘fissures’ or dividers. The right lung has three lobes but the left lung has only two, because the heart takes up some of the space in the left side of our chest. The lungs can also be divided up into even smaller portions, called ‘bronchopulmonary segments’.

• Trachea:The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi. At the top of the trachea the cricoid cartilage attaches it to the larynx. This is the only complete tracheal ring, the others being incomplete rings of reinforcing cartilage. The trachealis muscle joins the ends of the rings and these are joined vertically by bands of fibrous connective tissue – the annular ligaments of trachea. The epiglottis closes the opening to the larynx during swallowing.

• Bronchus:They are two tubes that what they do is carry air to lungs.

ILLENESSES:

• Asthma Systoms:

cough

wheezing,

chest pressure

difficulty breathing

• Pneumonia Systoms:

chest pain

confusion

cough

fatigue

RELATHIONSHIP:

Circulatory system:

The circulatory and respiratory system work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
