Which human body system interacts with each cell of the body?
A) the circulatory system
B) the digestive system
C) the muscular system
D) the skeletal system
A. The circulatory system transports blood to all the cells of the body
How are the alveoli in the lungs and the villi in the small intestine similar?
A) Both are structures located in the respiratory system.
B) Both are structures located in the digestive system.
C) Both are structures in which substances pass through capillary walls into the blood.
D) Both are structures involved in coordination and movement.
C. Both alveoli and villi are tiny structures containing capillaries in which substances pass to and/or from the blood. In the alveoli of the respiratory system, oxygen and carbon dioxide pas into and out of blood; in the villi of the digestive system, nutrients pass into the blood.
In the 17th century, English physician William Harvey concluded that blood in the veins flows toward the heart. Which of the following facts helps support Harvey’s conclusion?
A) The heart pumps about 1,800 gallons of blood per day.
B) The heart has four chambers: two atria and two ventricles.
C) Large veins branch into smaller blood vessels called capillaries.
D) Veins have values that allow blood to flow in one direction only.
D. Of the four facts given, this is the only one that involves the direction of flow of the blood. Therefore, it helps to support Harvey’s conclusion that blood in the veins flows toward the heart.
