Clothing: - Clothing will absorb the sweat that is caused by the environment.

Heat acclimation: - The body is able to become accustomed to high-heat environments. - During heat acclimation, the body is able to be highly efficient, and while large amounts of sweat are produced, the body continues to feel comfortable.

“Adam” - A dummy built to mimic the sweating of a real human being. - Uses: o Evaluating air conditioner usage o Testing clothing o Testing heating devices

Respiratory system: Purpose: - Brings in oxygen, and removes Carbon Dioxide

Air through nose and lungs: - Air is introduced to the body through the nasal cavity - Air then goes through the pharynx, then the glottis - Then air goes to the larynx, trachea, and then lungs

Upper respiratory tract: - Nasal cavity: o Air is introduced to the body - Pharynx: o Connects larynx to nasal cavity - Larynx: o Connects trachea and pharynx

Pharynx: - Food and air passages cross in the pharynx - The larynx and esophagus work together to keep food and air going in the right places

Lower respiratory tract: - Trachea: o Leads to the bronchi - Bronchi o Covered in bronchioles - Lungs: o Store oxygen o Remove CO2

Gas exchange: - Alveoli is responsible for gas exchange

Infections and illnesses: - Upper respiratory system: o Sinusitis o Tonsillitis o Laryngitis - Lower respiratory system: o Bronchitis o Pneumonia

Dangers of smoking: - Lung cancer - Chronic bronchitis - Emphysema

Cardiovascular system: Parts: - Blood vessels - Heart

Functions of cardiovascular system: - Pump pressurized blood - Blood vessels move blood

Blood vessels: - Types: o Veins o Capillaries o Arteries - Structure: o Inside layer of cells is called the endothelium o Middle is made of muscle o Outside is tissue

Heart as a “double pump”: - Left ventricle sends blood all through the body - Right sends blood to the lungs
