A) A lack of sufficient blood flow to a group of cells B) An abnormality involving platelets C) A high level of oxygen in the veins D) too much elasticity in a blood vessel If you have blood type B, then that means you can give blood to someone who has ? A) Blood types A and AB B) Blood types B and AB C) Only blood type AB D) Only blood type O In the picture, “B” is pointing to? A) B) C) D) The larynx The esophagus The trachea The bronchi The Epiglottis A) Covers the air passageway of the trachea during swallowing B) Is the air passageway that branches into each lung C) Contains passageways for both food and air D) Is also known as the voicebox Bronchioles are A) Located at the back of nasal cavities and the mouth B) Tiny air sacs where gas exchange occurs C) Are also known as vocal cords D) A network of tiny tubes that connect the alveoli in the lungs to the bronchi Expiration occurs when A) The diaphragm relaxes and rib cage muscles contract B) The diaphragm contracts and the rib cage muscles relax C) The diaphragm and rib cage muscles relax D) The diaphragm and rib cage muscles contract The Diaphragm A) Is a Dome shaped muscle below the chest cavity B) Is the site of gas exchange between the atmosphere and the blood C) Is a membrane that decreases the friction from the movement of the lungs during breathing D) Moistens and filters air before it moves back to the throat _______ is surrounded by capillaries. A) each lung B) the trachea C) the aorta D) each alveolus Systolic pressure is caused by contraction of the heart’s?
