Hb (hemoglobin) binds to CO (carbon monoxide) with a higher affinity than oxygen and stabilizes the R (relaxed) state - True When hemoglobin changes from the T to the R, it has a high affinity for oxygen - True When hemoglobin changes from the R to T, it has a low affinity for oxygen - True Cooperatively refers to - structural changes that increases the affinity for oxygen in hemoglobin When the oxygen concentration is high, the heme shape is planar. When the oxygen concentration is low, t...

3 cardiovascular adjustments - 1. ANS adjustments which increase Q 2. Redistribution of Q 3. Increased venous return in proportion to increased Q Q - cardiac output = (EDV - ESV) x HR - increases with increased exercise intensity Fick equation - VO2, Q, and aterial-venous O2 difference O2 content - O2 bound to Hb + O2 dissolved in plasma O2 content in different areas of the body - active muscle < mixed < inactive < arterial arterial capacity, arterial content, mixed ve...

What are the signs of the hypovolemic shock ? Decrease BP, increase HR, Cool/clammy skin, pale What is the sympathetic nervous system's fight or flight response ? Dilation of pupils, increased respiratory rate and heart rate. What is the net effect of the renin-angiotensin-aldosterone system in compensatory shock ? Increase blood pressure through vasoconstriction and increased venous return through retention of sodium and water. What are the most important cells in the inflammato...
