RESPIRATORY SYSTEM

Function of Respiratory System To provide to enter the bloodstream where it will be carried to every cell for the process of. This produces for. oxygen Aerobic respiration energy metabolism In addition, this system allows to be exhaled from the body. carbon dioxide

So how do organisms Respire? diffusion skin spiracles/tracheal tubes stomates gills

nose mouth Human Respiratory System

The Nasal Cavity has space which the air, mucus membranes which the air and nose hairs which the air. warms moisten filter

nose mouth Human Respiratory System pharynx larynx

How do you speak/choke/have food come out your nose? Eww!! Uvula, but what’s that hanging off it? Adam’s apple

nose mouth Human Respiratory System pharynx larynx trachea bronchi

Bronchi and trachea: Rings of cartilage to keep open, mucus and beating hairs to clear passageway

nose mouth Human Respiratory System pharynx larynx trachea bronchi lung bronchiole alveoli

Lungs contain bronchioles and alveoli. bronchiole1. 2.alveoli 3.capillary

nose mouth Human Respiratory System pharynx larynx trachea bronchi lung bronchiole alveolidiaphragm

So……why do we breathe? And how? We mostly breathe to rid ourselves of CO 2 Inhale: ribs up and out, diaphragm down. Exhale: ribs down, diaphragm up.

Respiratory Disorders: ASTHMA Causes release of histamine which…

…causes a runny nose, sneezing, itchy, watery eyes and possibly- ASTHMA! antihistamine inhaler

Respiratory disorders: BRONCHITIS Inflammation caused by: virus, bacteria, asthma, smoking

Smoking causes: Bad hair! Bad stink! Bad teeth! Bad skin! ADDICTION!!

That was then… This is now!

Smoking causes: EMPHYSEMA Alveoli are overstretched and lose their elasticity

Smoking causes cancer laryngectomy

Mount Everest: 29,032 ft above sea level Mauna Kea, Hawaii 13,000 ft above sea level (33,000 ft from the sea floor!) Chimborazo, Ecuador 20,500 ft above sea level Farthest point from the Earth’s Center
