Respiratory
This term refers to the proportion of total pressure contributed by that specific gas
What is partial pressure?
The functional unit of the nervous
system
What are neurons?
These two systems impact the same cells and work together to change function. Which one works slower?
What is the endocrine system?
This molecule stores oxygen in muscle tissue.
What is myoglobin?
If you are metabolizing this
then volume breathed in is
greater than volume
breathed out
What are fats?
Axons from this animal were so large Hodgekin and Huxkley could insert wires directly to record action potentials
What is the squid?
This type of chemical signaling diffuses locally and acts on nearby cells
What is paracrine signaling?
Blood leaving the right ventricle enters these vessels.
What are the pulmonary arteries?
This protein comprises the thick filaments of muscle.
What is myosin?
This rightward shift of the oxygen–hemoglobin dissociation curve occurs when pH decreases, temp increases, or CO₂ levels increase
What is Bohr Shift?
This type of signaling results in change in Vm in
postsynaptic cell, is fast, and may elicit an action potential in
the postsynaptic cell
What is electric signaling?
This type of cell releases secretions out
What are exocrine cells?
The release of this chemical by the sympathetic nervous system causes the heart rate to increase.
What is epinephrine?
This contractile unit constitutes the individual functional component of muscle fibers.
What is a sarcomere?
Besides in utero, in what other situations might
higher affinity hemoglobin have an advantage?
What is high altitude?
This division of the nervous system includes nerves that carry sensory information to and motor commands from the brain and spinal cord.
What is the PNS?
This type of hormone is lipid soluble and binds to receptors inside the target cell
What are steroids?
Blood leaving the left ventricle of the heart enters this large vessel.
What is the aorta?
This protein has binding sites for myosin.
What is actin?
Used to calculate cardiac output, this principle relates oxygen uptake to differences between arterial and venous blood
What is the Fick Principle?
Rather than having CNS and PNS, invertebrates have this as their nervous system
What is distributed ganglia?
This hormone is released from the thyroid gland, increases metabolic rate and heart rate, and is synthesized from tyrosine
What is Thyroxine?
The heart's own pacemaker is located in the sinoatrial node; a part of this chamber of the heart.
What is the right atrium?
The presence of this ion is required for cross bridge formation during muscle contraction.
What is calcium?
