What are the parts of the respiratory system describe each part?

Answer 1

Respiratory System is the only life support system under voluntary and automatic control. The respiratory system functions to obtain the oxygen necessary to create energy for body functions and to eliminate the carbon dioxide produced during cellular metabolism. It it also connected to Emotion.

Respiratory System Organs:

Nose and nasal cavity

Sinuses

Pharynx

Larynx

Trachea

Lungs

Diaphragm

Thorax

Nose and Nasal Cavities

-Nostrils (external nares): separates the nasal cavities from the oral cavity

-Nasal Cavities: divided into two passages by the nasal septum, which is made up of hyaline cartilage

-Hard palate: hard portion of the roof of the mouth, separates the nasal cavities from the oral cavity. It's made up of the maxillary and palatine bones

-Soft palate: separates the pharynx into the nasopharynx and oropharynx

-Vestibule: first portion of the nasal cavity, Covered with tiny hairs that filter the air that goes into the system

-Conchae: Shelf-like progections from the lateral wall of the nose

-Meatus: Between the conchae. helps churn the air which enables the large particles to stik to the mucus lining

-Nasolacrimal duct: the tear duct that opens into the nose from the conjuctiva of the eye

-Nasal epithelium: Mucous; cleans the air that enters the nasal cavity & brings it to body temp. and humidity

-Lamina propria: connective tissue lining the epithelium

Sinus Cavities: Four groups of air-filled spaces that open into the internal nose.

Sphenoid sinus - posteriorly and superiorly, closely related to the pituitary gland

Maxillary sinus - in the maxillary bones

Ethmoid sinus - superior and posterior part of the nasal cavity

Frontal sinus - deep in the medial part of the eyebrows

Pharynx (Throat) - Passageway for both air and food

Larynx (Voice box) - Connects the pharynx with the trachea

Trachea (windpipe) - Main airway to the lungs

Lungs - Primary organs of respiration (Right Lungs;3 lobes & Left Lung; 2 lobes)

Diaphragm- Dome shaped sheet of muscle attached to thoracic wall that separates lungs and thoracic cavity from the abdominal cavity.

Thorax (Chest Cavity) - upper region of the torso

KEY TERMS

Peristalisis: rhythmic contraction of smooth muscles that propels products of

digestion along the tract from the esophagus to the anus

Respiration: Movement of air in and out of lungs.

Answer 3

It is one out of the 12 organ systems of the human body. This system involves the body breathing or inhaling in oxygen or air into the body to give the rest of the body oxygen. The respiratory system is made out of the lungs which takes in oxygen I to the body and takes out carbon dioxide lf the
