Respiratory System

The respiratory system has the most direct relationship with the ____system because___

• cardiovascular-the respiratory system provides the oxygen that the cardiovascular system transports throughout the body

• skeletal-the calcium from bones is necessary for gas exchange in the lungs

• reproductive- smokers with lung damage could pass it on to their offspring

• integumentary-oxygen can also be absorbed by the skin

A condition that causes constriction of the bronchioles, often due to an allergic reaction is called

• emphysema

• asthma

• pulmonary bronchitis

• respiratory distress syndrome

Which of the following is NOT TRUE about alveoli?

• they are surrounded by fluid for efficient gas exchange

• they line all of the upper and lower respiratory passages

• they are made of simple squamous cells

• they contain white blood cells/macrophages

• pleural membranes

Which of the following is NOT part of the upper respiratory tract?

• nasal cavity

• bronchioles

• pharynx

• larynx

Nasal hairs function in

• warming the air breathed in

• blocking dust and debris

• gas exchange

• producing mucus

What structural feature supports the trachea to keep it open for air passage?

• rings of cartilage

• cilia

• visceral muscle

• the rib cage

Respiratory distress syndrome, which often occurs in newborns is caused by

• exposure to pollution

• damage to respiratory nerves

• lack of surfactant/lubricant in the alveoli

• smoking

The anatomical term for the opening of the larynx is called the

• alveoli

• windpipe

• diaphragm

• glottis
