  2. Red Blood Cells
    major component of blood that travels through various size blood vessels, whose job is to carry oxygen to all parts of the body
  3. Epithelial
    line in the oral cavity and are shed from the surface. bacteria are often seen on these cells
  4. Intercalated Disks
    tight junction where cardiac muscle cells branch and join with one another end to end 

    allows for the communication of information from one cell to another
  5. Red Bone Marrow
    a specialized blood-producing tissue found in the cancellous bone
  6. Compact Bone
    the outter layer of long bone tubes
  7. Cancellous Bone
    the inner layer of bone, which is spongy
  8. Yellow Bone Marrow
    consists primarily of fat cells, gradually replaces red marrow in some bones as the skeleton matures
  9. White Blood Cells
    part of the body's defense mechanism
  10. Spirochaetos
    anaerobic bacteria that are found in dental cavities and other holes
  11. Pericardium
    outtermost layer of the heart

    double-layered sac that holds the heart in the center of the chest without hampering its movements
  12. 3 Layers of the heart
    1) Pericardium

    2) Myocardium

    3) Endocardium
  13. Myocardium
    middle layer of the heart

    composed of cardiac muscle tissue and makes up the bulk of the heart
  14. Endocardium
    the thin innermost layer that lines the cavities of the heart
  15. Alveoli
    microscopic air sacks bundled at the ends of bronchioles

    where gas exchange occurs in the lungs
  16. Skin
    largest organ of the human body

    functions as a protective coating, and forms an effective barrier against disease causing microbes

    insulates and cushions the underlying body tissues and protects the body from damage 
  17. Gregor Mendel
    monk who is credited with being the "father of genetics"

    1st to discover genes and alleles 
  18. Karyotype
    refers to the kinds of chromosomes an individual has present in the nucleus of each of his cells
  19. Watson and Crick 1953
    discovered the helical structure of DNA
  20. Purines
    adenine and guanine

    bases in DNA that are larger than pyrimidine bases
  21. Pyrimidines
    Cytosine and thymine

    DNA bases that are smaller than purines 
  22. chromosomes
    composed of chromatin
  23. Chromatin
    composed of double-stranded DNA
  24. DNA
    composed of nucleotides
  25. Nucleotides
    composed of 

    • - phosphate
    • - deoxiribose
    • - base 
  26. tRNA
    how ribosomes attract the coded amino acids
  27. Transduction
    process from sensory stimulus to nerve impulse
  28. Neurons
    nerve cells that are the structural and functional unit of the nervous system
  29. Central Nervous System (CNS)
    made up of the brain and the spinal cord

    responsible for majority of the body's interpretative activities as it receives data from the major sensory organs of the body 
  30. Peripheral Nervous System
    sysem that contains all other component structures

    (not the brain or spinal cord) 
  31. Afferent Neurons
    (sensory neurons)

    convey information (provided by sensory receptor cells) to the central nervous system
  32. Efferent Neurons
    (motor neurons)

    composed of 2 subsets (somatic and autonomic nervous system)

    usually glands or muscles
  33. Autonomic Nervous System
    part of efferent system that controls our subconcious activities, such as digestion

    divided into the sympathetic and parasympathetic divisions
  34. Somatic Nervous System
    portion of efferent system mainly composed of the cranial and spinal nerves and contros the voluntary activities of the body
