A.

Pulmonary valve

B.

Aortic valve

C.

Tricuspid valve

D.

Bicuspid valve

Answer and Explanation

The Correct Answer is C, A, D, B

  • Deoxygenated blood from the body enters the right atrium, passes through the tricuspid valve into the right ventricle.
  • From the right ventricle, blood moves through the pulmonary valve into the pulmonary arteries and goes to the lungs for oxygenation.
  • Oxygenated blood returns to the left atrium and passes through the bicuspid (mitral) valve into the left ventricle.
  • Finally, the left ventricle pumps oxygenated blood through the aortic valve into the aorta for distribution to the body.

Correct Answer is A

Explanation

A. This allows for rapid exchange of oxygen and nutrients: Capillaries have thin walls (one cell thick) to facilitate the rapid diffusion of gases (oxygen and carbon dioxide), nutrients, and waste products between blood and tissues.

B. This allows for red blood cell formation to occur: Red blood cells are formed in the bone marrow, not in capillaries.

C. There is no blood pressure within the capillaries: There is still blood pressure within capillaries, although it is lower than in arteries, so this is incorrect.

D. Blood does not travel through capillaries: Blood does indeed travel through capillaries as part of the circulatory system.

Correct Answer is A

Explanation

A. Parietal pleura: The parietal pleura is the outer layer of the pleura that lines the thoracic cavity and is connected to the thoracic wall.

B. Diaphragm: The diaphragm is the main muscle involved in respiration, but it is not part of the lung's outer layer.

C. Pleural cavity: The pleural cavity is the space between the parietal and visceral pleura, filled with pleural fluid to reduce friction.

D. Visceral pleura: The visceral pleura is the inner layer that covers the lungs but does not connect to the thoracic wall.
