Blood Pressure

• Systole Diastole
• Systolic max force from ? contraction
• Diastolic pressure between ? contractions
• Fluid Dynamics
• Cardiac output
• Blood volume
• Peripheral resistance
• Elasticity of vessels
• Viscosity of blood

Blood Pressure

• Other factors that affect BP
• Emotions SNS
• Environmental Temperature
• Activity levels
• Hypertension
• gt140 mmHg systolic, gt90 mmHg diastolic
• Risk factors
• family Hx
• body weight
• age
• gender
• race

21
Diseases of the Cardiovascular System

• Myocardial Infarction
• Angina Pectoris
• Stroke

Immune System Organs
23
Immune System

• Organs of the immune system
• lymphocytes white blood cells
• from lymphatic or lymphoid organs
• bone marrow
• thymus
• lymph nodes
• spleen
• originate in bone marrow, migrate to thymus,
  mature into leukocytes
• lymph nodes capture antigens and hold lymphocytes
• lymph vessels ultimately empty into blood supply
• can spread cancer cells
• spleen filters blood

24
Soldiers of the Immune System

• White blood cells
• phagocytes nonspecific immunity
• macrophages and monocytes
• lymphocytes respond to specific antigens
• T-cells cell-mediated immunity
• Killer T cells
• Helper T cells
• Memory T cells
• Suppressor T cells
• Delayed hypersensitivity T cells

25
Soldiers of the Immune System

• B-cells antibody-mediated immunity
• B-cells produce plasma cells which produce
  antibodies (immunoglobulins - Ig)
• Igs attach to antigen and identify it for
  destruction
• Memory B-cells

26
Helper T Cells
27
The Immune Response

• First lines of defense
• skin
• mucous membranes of respiratory and digestive
  tracts
• Next non-specific and specific immune processes
• phagocytes, B-cells, helper T-cells destroy
  antigen
• Finally killer T-cells destroy invaded cells

28
Immune System and the Brain
29
Auto-immune Diseases

• Rheumatoid arthritis joints
• Rheumatic fever heart muscle
• Multiple Sclerosis myelin
• Lupus erythematosus skin and kidneys

30
Genetics

• Chromosomes contain genes
• DNA
• dominant and recessive genes
• phenotype and genotype
• mutations
• Polygenetic inheritance
• likely the case for many behavioral traits
