Which of the following best describes the way in which epithelial tissues are characterized?
answer
By the shape of the cells at the apical surface and the arrangement of the nuclei
question
Match each of the types of epithelial tissue at the left to the correct following functions at the right.
answer
1)simple squamous:thin layer of cells that allows the fast diffusion of substances.
2) stratified squamous: Many layers of cells stacked on top of one another, providing a significant amount of protection of abrasion.
3) simple cuboidal: allows for rapid diffusion but also produces secretions.
4) Stratified cuboidal: produces secretions while preventing damage to the underlying layers.
5) simple columnar: cells are the most active in secretion and absorption.
question
Organizing Connective Tissue
Drag and drop each of the following types of connective tissue proper so that it matches with the correct classification.
Defining the Function of Connective Tissue
Match each of the following connective tissue types with the correct phrase/description.
answer
1) loose connective tissue: surrounds the human eye in order to protect and cushion it.
2) Dense connective tissue: attaches muscle to bone and has the ability to to resist tension to the ability due to thick collagen fibers.
3) Bone: has organic and inorganic substances in the extracellular matrix.
4) Blood: Fluid medium used for the transport of gases and nutrients.
5) Cartilage: ground substance is able to hold fluid and is resistant to compression.
question
Differentiating Between Epithelial Tissue and Connective Tissue
Sort each of the following phrases into the appropriate bin - the two bins represent the two categories of tissues: epithelial and connective.
answer
Epithelial Tissue: Apical surface that faces an open space, straitified columnar, can aid diffusion and protection, tightly packed cells held together by cell-to-cell adhesion molecules, can aid in absorption and secretion.
Connective tissue: Dense irregular, binds and protects, stores nutrients and transports, can have large amount of collagen
