Blood Basics
This type of tissue is blood.
What is fluid connective tissue?
This chamber receives oxygen-poor blood returning from the body.
What is the right atrium?
This phase of the cardiac cycle is when the heart relaxes.
What is diastole?
This structure blocks the larynx during swallowing.
What is the epiglottis?
This is the primary function of the respiratory system.
What is gas exchange?
These are also known as erythrocytes.
What are red blood cells?
These vessels transfer blood between arteries and veins.
What are capillaries?
What is bradycardia?
The right lung has this many lobes.
What are three lobes?
This is the difference between ventilation and respiration.
What is ventilation is movement of air, while respiration is gas exchange?
This is the normal pH range of human blood.
What is 7.35-7.45?
This is the largest artery in the body.
What is the aorta?
These electrical signals trigger the mechanical contraction of the heart.
What are action potentials?
These three divisions categorize the bronchi.
What are primary, secondary, and tertiary bronchi?
These are the two primary muscles of inspiration.
What are the diaphragm and the external intercostal muscles?
These are the three steps of hemostasis in correct order.
These are the only two vessels that break the "arteries carry oxygen rich blood" rule.
What are the pulmonary artery and pulmonary veins?
These are the highest and lowest pressures exerted on arterial walls during the cardiac cycle.
What are systolic and diastolic blood pressure?
These are the four layers of the tracheal wall.
What are mucosa, submucosa, cartilage layer (hyaline cartilage), and adventitia?
Approximately this many alveoli are found in the lungs (total).
What are about 300 million?
This hormone, produced primarily by the kidneys, regulates red blood cell production in bone marrow.
What is erythropoietin (EPO)?
This system allows the heart to beat independently of nervous system input and includes the SA node, AV, node, bundle branches, and Purkinje fibers.
What is the intrinsic cardiac conduction system?
Name three extrinsic factors that can influence the cardiac cycle.
What are hormones, autonomic nervous system input, ion levels, body temperature, cardiovascular health, age, or gender (Any 3)
This molecule reduces surface tension in the alveoli and prevents collapse.
What is surfactant?
This is the balanced chemical equation for cellular respiration.
What is C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP?
