Cuneiform cartilages

Arytenoid cartilages

Carina

are small so that they slip between endothelial cells of capillaries to fight infection in the surrounding tissues

None of the above is related to plasma cells.

have a great deal of rough endoplasmic reticulum reflecting the fact that they secrete a tremendous amount of protein (antibody)

are large so that they can envelope their prey by phagocytosis

have a great deal of rough endoplasmic reticulum to dispose of ingested pathogens

Defective antibody secretion

Lack of mature T lymphocytes

Decreased macrophage activity

Impaired B cell activation

Reduced complement proteins

It depends on the complete lack of surface tension on the alveolar wall.

It is driven by increased blood  levels.

It requires contraction of abdominal wall muscles.

It is a passive process that depends on the recoil of elastic fibers that were stretched during inspiration.

Diaphragm would contract, internal intercostals would relax

Diaphragm would contract, external intercostals would relax

External intercostals would contract, and the diaphragm would relax

Internal intercostals and muscles of the thorax would contract

The thymus consists mainly of lymphoid tissue.

Antibodies mark antigens for destruction.

Only lymph nodes filter lymph.

T lymphocytes originate from the red bone marrow.

concentration of oxygen and/or total atmospheric pressure is higher at higher altitudes

basal metabolic rate is higher at high altitudes

concentration of oxygen and/or total atmospheric pressure is lower at high altitudes

temperature is lower at higher altitudes
