SYSTEM

System is a complex of organs that are working together to be functional.

• BEA DIÑO

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. It is accomplished by breathing. The human body needs oxygen to sustain itself. A complete lack of oxygen is known as anoxia and a decrease in oxygen is known as hypoxia. After four to six minutes, brain cells without oxygen are destroyed and an extended period of hypoxia leads to brain damage and ultimately death.

OUTLINE

I. Functions of the Respiratory System

II.Divisions of the Respiratory System

As to Function• The Conducting

III. Parts and their Functions

1.Oxygen Transport• Respiration• Mechanism of

BreathingVentilation InhalationExhalation

2. Transport of Gases in the Blood

CONDUCTING ZONE

• Consist of the nose, pharynx, larynx, trachea, bronchi, and bronchioles.

• These structures form a continuous passageway for air to move in and out of the lungs.RESPIRATORY ZONE

• Found deep inside the lungs

• These thin-walled structures allow inhaled oxygen to diffuse into the lung capillaries in exchange for carbon dioxide.

UPPER RESPIRATORY TRACT

• Structures found in the head and neck.

• Composed of nose, larynx, and pharynx.

LOWER RESPIRATORY TRACT

• Structures located in the thorax or chest.

• Includes the trachea, bronchi, and lungs (bronchioles, alveoli, and alveolar ducts).

PARTS OF THE HUMAN RESPIRATORY SYSTEM

•JANINA GUILLERMO

PULMONARY VEIN

Pulmonary vein is a blood vessel in the respiratory system that carries oxygenated blood away from to heart to the lungs. HYPERVENTILATION

Hyperventilation is a phenomenon in the respiratory system where levels of carbon dioxide and hydrogen ions increases in body fluids which results to impulses of voluntary inhibition of breathing, where one is force to take a deep breath and rapid breathing to accumulate oxygen for the body.

OXYGEN

Oxygen is an organic element essential for sustaining life of living organisms most especially for humans. This serves as the life for red blood cells which drives the cells and tissues to work and function at their normal state and also serves as the distributor of nutrients and materials in the body.

•JANINA GUILLERMO

CAPILLARIES

Capillaries are the body's smallest blood vessel that helps to exchange water, carbon dioxide, oxygen and many other nutrients.

• BEA DIÑO

NOSTRILS

Nostrils is an organ part of the respiratory system which is one of the passageway of air.

• BEA DIÑO

LARYNX

Larynx or known as voice box is a part of a throat that is responsible for breathing, sound production and connects the pharynx to the trachea for breathing and eating.

•GABRIELLE CABANSAG

TRACHEA

Trachea is at the lower border of a larynx that allows the passage of air that connects the larynx to the bronchi.•GABRIELLE CABANSAG

BRONCHI

Bronchi is at the lower border of trachea that allows the passage of air through the respiratory tract that conducts air into the lungs.•GABRIELLE

•AILA YALUNG

LUNGS

The Human lungs are pair of large, spongy, air-filled organs located on either side of the chest optimized for gas exchange between our blood and the air we breathe as it facilitates the process of taking in oxygen that eventually enters the blood, and gets rid of carbon dioxide, a waste product of the cells.

•AILA YALUNG

ALVEOLI

The Alveoli are tiny sacs that are known to be the functional unit of the lungs surrounded by tiny capillaries that allows oxygen and carbon dioxide to move within the lungs and bloodstream, which gives rise to the process known as the transfer of gases.

•AILA YALUNG

DIAPHRAGM

The Diaphragm is a dome-shaped sheet of strong muscle which separates the chest from the abdomen and plays a lead role in breathing because whenever we breathe out, it moves upward, forcing the chest cavity to get smaller and pushing the gases in the lungs up and out of the nose and mouth.

INVENTED WORDS

ENTRIT

The Entrit is a process of passing across or through an area which is directly involve in the human respiratory system in order to describe the two gases that pass through a same membrane to sustain the needs of the cells within the body.

•AILA YALUNG

HYPOLARYNSITIS

• Hypolarynsitis is a kind of illness that is related to sore throat, the larynx will have an inflammation or will swell due to the damaged tissue on the larynx caused by a person who drinks too much cold liquid and who sings a high pitched note.

•GABRIELLE CABANSAG

VEINTRIES

Veintries is a combination of blood vessels in the whole body mainly found in both respiratory and circulatory system that coordinates to bring oxygenated blood and some organic nutrients back and forth the heart, lungs and different organs that needs these essential materials to continue the functioning of their systems.

•JANINA GUILLERMO

CARBOXYGEN

Carboxygen is an organic compound of gases that occurs during the inhalation and exhalation process of the lungs that diffuses in the membrane essential for the life of red blood cells and transport of some nutrients and materials throughout the body.
