Answer 21

Clinical Chemistry- study of analytes that is present in the samples
Hematology- assessment of a cellular element to identify diseases
Blood banking/Immunohematology- transfusion medicine, checking of compatibility and safety of donors blood with the recipient
Microbiology- study of bacterias, viruses, fungi and parasites
Clinical Immunology and Serology- Infectious diseases diagnosis by detection of Antibodies in serum and other bodily fluids

Question 22

GROSS ANATOMY

Question 26

4 Basic tissue types of the body

Answer 26

MUSCLE TISSUE- for contraction, formed by myogenesis (cardiac muscle, skeletal muscle, smooth muscle) NERVOUS TISSUE- aka neural tissues, CNS (brain and spinal cord) and PNS (peripheral nerves), mainly composed of neurons (receiving and transmitting of nerve impulses), neuroglial cells (helps in assist in propagation of nerve impulses and provide nutrients to neurons) CONNECTIVE TISSUE- 3 main components of CT fibers, ground substances , cells. General connective tissue (Loose connective tissue highest in ground substances, Irregular dense connective tissue, Regular dense connective tissue) Special connective tissue (cartilage, bone, blood, lymph and hematopoetic tissue). CT developed from the mesoderm EPITHELIAL TISSUE- lines outer surfaces, Classes of ET (Squamous- flat and scale like cells that is wider than their height, usually lining the mouth, esophagus and blood vessels) (Cuboidal- square in appeareance/cubed shape, for secretion and excretion purposes, mainly found in kidney, salivary glands and pancreas) (Columnar- elongated, mainly for absorption, secretion and excretion mainly found in the respiratory system)

Question 27

LAYERS OF THE EPITHELIAL TISSUE

Answer 27

Simple- one layer Stratified- two or more layers Pseudostratified- false layering (one layer only but looks like it has a multiple layer)

Question 28

Type of muscle tissue for voluntary response

Answer 28

Skeletal Muscle

Question 29

What type of epithelial muscle lines the trachea?

Answer 29

Ciliated pseudostratified columnar epithelium
