- - - - or pressorecptors that detect changes in BP in aorta and carotid arteries
    - - that detect changes in key blood chemical concentrations (H+, CO2, and O2)
    - - vasomotor inhibited (dilate), cardioinhibitory center stimulated-parasympathetic, cardioacceleratory center inhibited-sympathetic
    - - vasomotor stimulated (constrict), cardioinhibitory center inhibited, cardioacceleratory center stimulated
  - - - (ADH) posterior pituitary gland, increases reabsorption of water by the kidneys (DCT) and causes vasoconstriction of arterioles during diuresis and during hemorrhage
    - - Renin released from kidneys, has four different targets that cause vasoconstriction of arterioles and causes the secretion of aldosterone (ADH+ stimulates cardiac output)
    - - stimulates red blood cell production
    - - causes vasodilation of arterioles and promotes the loss of salt and water in urine
    - - increases CO (rate & force of contraction) and causes vasoconstriction of arterioles
    - - increase Na+ and water reabsorption in the kidneys
    - - casues vasodilation of arterioles (Plays a key role in inflammation)
- - - - blood donation 500 ml 10%, vasomotor enough to restore pressure and flow
      - venous reserve (venoconstriction) slow moving blood (liver, bone marrow, and skin) restore 15-20% loss
      - sympathetic stimulation (major loss of blood) E, NE, ADH, REnin
    - - ADH, EPO, Aldosterone, and increase thirst
  - - - hypotension
      - pale, cool, and moist skin
      - confusion and disorentation (no blood to brain)
      - rapid weak pulse
      - no urine
      - drop in blood pH
- - - - aneursym, stroke, myocardial infarction, or massive blood loss
- - - - opposition to blood flow usually due to friction
      - total peripheral resistance- vascular resistance, viscosity, tuberlence
      - total blood vessel length: blood vessel length up: R up: BP up--normally constant, direct relationship
      - blood vessel radius (radius up: R down: BP down) most significant factor in determining BP. indirect relationship
    - - liquids cannot be compressed (hydrostatic pressure) liquid will flow from high to low concentrations
      - circulatory pressure-100 mmHg base of aorta (pressure gradient), needed to force blood through arterioles and into capillaries
      - arterial pressure (measured on the arm), capillary pressure, venous pressure
    - - Blood viscosity- (up viscosity: up R: up BP) normally constant, direct relationship
  - - - 18 mmHg (venule side of capillary)
      - 2 mmHg Vena Cava pressure of veins 18-2=16 mmHg
      - BOP increase CHP (venule side) fluid moves into the vessel
    - - the pressure exerted by blood on the walls of the blood vessels 120/80 normal, tachycardia > 100 bpm, bradycardia<60 bpm
      - the arterial blood pressure rises to its maximum during systole (contraction) and falls to its lowest during diastole (relaxation)
      - CHP increases BOP (arterial side) fluid moves into tissues
    - - capillary pressure pushes on capillary walls, permeably to ions, nutrients, organic wastes, dissolved gasses & water
      - 100 mmHg (aorta) produced by the heart
      - 35 mmHg (arterial side capillary)
      - CHP=BOP no net fluid movement
      - four parts- communication between plasma and interstitial fluid, speeding distribution throughout tissues, assisting the movement of insoluble lipids and tissue proteins, flushing bacterial toxins & chemicals stimuli to the lymphatic system
