All vertebrates except cold-water ice fish transport oxygen via hemo-globin packaged in red blood cells (RBCs). Vertebrate RBCs vary in size by thirty-fold. Differences in RBC size have been known for over a century, but the func-tional significance

We examined metabolic rates in 25 deer mice, Peromyscus maniculatus nebrascensis, held at an ambient temperature of 10 °C and found that all of them had the ability to enter torpor. However, we found a gradation between the most torpor-sensitive and

Tadpole shrimp, Triops loregicaudatus live at the bottom of small ephemeral pools where the supply of oxygen is extremely variable. When oxygen tensions in the lower water layers are low, shrimp make numerous trips to the surface in order to obtain o

Tissue capillarity and tissue enzyme activity (citrate synthase and lactate dehydrogenase) were determined for two red muscles and two white muscles from the domestic chicken during normal maturation and, for one red muscle, during muscle hypertrophy

Timed perfusions of capillaries in soleus, vastus lateralis, and diaphragm of rats were determined by injecting a fluorescent dye into the aorta or right atrium. At preselected time intervals after dye injection, the circulation was interrupted, skel

The effects of changes in oxygen supply and oxygen demands on fiber cross-sectional areas, capillary densities and capillary to fiber ratios were determined in three skeletal muscles of rat. The muscles examined were the vastus lateralis, soleus, and

In chicks the ability to regulate body temperature to adult levels develops during the first 2 weeks of life. We examined whether the ability of young chicks to regulate body temperature is increased by elevated levels of the thyroid hormone 3,3′5-

Rates of oxygen consumption ( V O2), body temperatures and pulmonary blood temperatures, blood gases and blood pH were measured for seven 4.9±0.8 (SE) kg tammar wallabies (Macropus eugenii) during rest and during treadmill hopping. For animals resti

The role of the insect tracheal system in gas exchange during cyclic ventilation is investigated using mathematical models. Three models are presented, one to describe the important elements of gas exchange during each of the three phases of cyclic v
