Which organ lies in the lateral and posterior portion of the left upper quadrant of the abdomen?

Spleen

What happens when blood volume is lost from the body?

The arteries contract to increase the blood pressure.

As the bronchus divides into smaller bronchioles, the terminal ends of these smaller passages form the:

alveoli

Both areas of the pons are used to:

augment respiration's during emotional or physical stress

Contraction of the right ventricle causes:

blood to flow into the pulmonary circulation.

The waste products of aerobic metabolism include:

carbon dioxide and water.

Mean arterial pressure (MAP) is a product of:

cardiac output and systemic vascular resistance.

Pathophysiology is the study of the functional changes that occur when the body reacts to a particular:

disease.

which of the following systems is responsible for releasing chemicals that regulate body activities?

endocrine

the leaf shaped flap of tissue that prevents food and liquid from entering the trachea is called the

epiglottis

Key hormones of the sympathetic nervous system include:

epinephrine and norepinephrine

Hemoglobin is a molecule that attaches to ______ and carries oxygen.
