Anatomy and Physiology of the Respiratory System

What is the significance of the pleural membrane in the respiratory system?

• It facilitates the opening and closing of the vocal cords.

• It allows for the expansion and contraction of the lungs.

• It separates the heart from the lungs.

• It filters air entering the alveoli.

During which process does oxygen move from the alveoli into the blood?

• Filtration

• Osmosis

• Diffusion

• Active transport

Which of the following gases is expelled from the body during exhalation?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

Which of the following is NOT a function of the respiratory system?

• Gas exchange

• Blood filtration

• Sound production

• Regulation of blood pH

Which of the following is a characteristic of alveoli in the lungs?

• Long and branching

• Disc-shaped and flat

• Tiny and thin-walled

• Muscular and acidic

Which organ system is responsible for gas exchange?

• Respiratory system

• Digestive system

• Muscular system

• Nervous system

What is the function of red blood cells?

• Transmit electrical signals

• Carry oxygen

• Produce movement

• Break down food

How are anatomy and physiology related?

• They are completely independent studies.

• Structure influences function, and function influences structure.

• Anatomy focuses on cells, while physiology focuses on tissues.

• Physiology is a prerequisite for anatomy.
