Nervous System
Detects disturbances in internal and external environments.
What is homeostasis?
The smallest vessels that are the site of gas and nutrient exchange.
Movement of gases between the air in the lungs and the blood; oxygen into blood and carbon dioxide out of the blood.
What is pulmonary diffusion?
Contraction phase where blood is pumped out of the chamber.
What is systole?
Diminishes intensity of process to return to initial status quo.
What is a negative feedback loop?
The only place in the body where arteries carry deoxygenated blood and veins carry oxygenated blood.
What is pulmonary circulation?
The use of oxygen in aerobic metabolism and production of carbon dioxide (within tissues).
What is cellular respiration?
What is diastole?
Points of connection & communication between 2 excitable cells.
What are synapses?
Intercommunication between 2 arteries ensuring blood flow to area even if one artery blocked.
What is anastomosis?
Diaphragm, external intercostals, scalenes, sternocleidomastoid, and pectorals minor.
Decrease heart rate, known as rest and digest.
What is Parasympathetic nervous system?
The cerebrum, occipital, temporal, parietal, frontal, cerebellum, diencephalon, brainstem, and spinal cord are all compromised of this system.
What is the central nervous system?
Has high mitochondrial density, extensive capillary network, and uses aerobic energy for contraction.
What is myocardial muscle fibers?
Airflow= P1-P2/Resistance
What is the Airflow Resistance formula?
What is sympathetic nervous system?
A measure of combined motor unit recruitment & rate of coding active motor units within a muscle is training adaptation.
What is neural drive?
Amount of blood pumped per contraction of ventricles.
What is stroke volume?
The rate of gas transfer (V gas) is proportional to the tissue surface area, the diffusion coefficient of the gas, and the difference in the partial pressure of the gas on the two sides of the tissue, and inversely proportional to to the thickness.
What is Fick's Law of Diffusion?
Electrical charge or impulse initiated & sent by neuron.
What is action potential?
