Cardiac 2 - Coggle Diagram

- - - - Thymus: R-cell factory, lymphocyte proliferation, thymocyte maturation into T cells, in front of the heart
    - - Spleen: loctaed in upper left abdomen, red pulp recycles RBC and houses macrophages, white pulp is site of lymphocyte maturation and antibody synthesis
      - Lymph nodes: filtering, trapping stations, lymphocyte activation
- - - - Cardiovascular center
      - Cardioinhibitory center
      - Vasometer center
    - - Increased BP: cardioinhibitory center
      - Decreased BP: cardioaccelerator center which stimulates vasomotor center
  - - - Medulla oblongata signals for hormones
      - Epinephrine and norepinephrine
      - increased heart rate, constrict blood flow and redirect blood flow
    - - Kidney responds to BP through nerve or Na concentration drop
      - Kidney secretes renin
      - Liver makes angiotensinogen and renin turns into angiotensin 1
      - Converted in lungs into 1 and endothelial cells for 2
      - Angiotensin 2
        
        Vasoconstrictor, increases BP
        
        Stimulates aldosterone release, reabsorbtion of salt in kidney
        
        Stimulates ADH
      - Erythropoietin
        
        Released by kidney when low blood flow or oxygen
        
        Stimulaes erythrocytes from bone marrow
        
        Increases blood volume, blood viscocity, blood pressure
      - High blood pressure
        
        Right atria responds to stretching
        
        Secrete atrial natriuertic peptide and brain natriuretic peptide
        
        appose angiotensin 2 and suppresses renin, aldosterone, and ADH
        
        Peripheral vasodilation
