William Harvey- father of physiology: discovered that blood circulated through the body in 1628.
Epithelial- lining or covering and glandular tissue.
Muscle- highly specialized to contract
Nervous- irritability and conductivity
Connective-Connects body parts; Must be living cells surrounded by a matrix. Example: Bone (cells sitting in lacunae in hardened matrix of calcium salts in Collagen fibers)
Bloodis considered to be a type of connective tissue. Even though it has a different function in comparison to other connective tissues it does have an extracellular matrix.
The matrix is the plasma and erythrocytes, leukocytes and platelets are suspended in the plasma.
Neutrophil – multi-lobed nucleus. Fine cytoplasmic granules
Eosinophil –cytoplasmic granules when red stained
Monocyte – kidney, oval, or lobe shaped nucleus.
Lymphocyte – large round nucleus.
Was Charlie Chaplin the father?
• In 1944 the actress Joan Barry (blood group A) sued Charlie Chaplin (blood group O) for support of her child (phenotype B).
• The blood group evidence was presented in court.
• The jury supported Joan Barry’s claim. Were they right?
The mother must be Heterozygous A (Ao)
The child must be Heterozygous B (Bo, inheriting the “o” from mother)
The child must have inherited a “B” from the father.
Charlie Chaplin was Homozygous O (oo) and therefore could not have been the father.
