Study Notes
Organ and Organ System
- Multicellular animals have specialized groups of cells called tissues.
- Tissues work together to form organs.
- Organs work together to form organ systems which perform specific functions.
- The division of labor in organ systems allows for efficient and coordinated activities in the body.
Frogs
- Frogs are amphibians, belonging to the class Amphibia of the phylum Chordata.
- The common Indian frog species is Rana tigrina.
- Frogs are poikilotherms, meaning their body temperature changes with the environment.
- Frogs exhibit camouflage with protective coloration.
- Frogs enter aestivation during summer to escape heat and hibernation during winter to escape cold.
Animal Tissues
- Multicellular organisms have specialized cells that work together to perform specific functions.
- These groups of similar cells with intercellular substances are known as tissues.
- Four basic tissue types are found in complex animals: Epithelial, Connective, Muscular, and Neural.
Epithelial Tissue
- Epithelium is a tissue that covers the surface of the body, body cavities, ducts, and tubes.
- It provides a covering or a lining for different parts of the body and has a free surface.
- Cells are tightly packed with little intercellular matrix.
- Simple epithelium is a single cell layer that functions as a lining for body cavities.
- Compound epithelium is composed of two or more layers and provides protective functions.
- Simple epithelium is further categorized based on cell structure as:
-
Squamous epithelium:
- Single layer of flattened cells with irregular boundaries.
- Found in blood vessels and air sacs of lungs.
- Function: diffusion boundary.
-
Cuboidal epithelium:
- Single layer of cube-like cells.
- Found in ducts of glands and tubular parts of nephrons in kidneys.
- Function: secretion and absorption.
-
Columnar epithelium:
- Single layer of tall and slender cells with nuclei at the base.
- Found in the lining of stomach and intestine.
- Function: secretion and absorption.
-
Squamous epithelium:
-
Ciliated epithelium:
- Columnar or cuboidal cells with cilia on their free surface.
- Present on the inner surface of hollow organs like bronchioles and fallopian tubes.
- Function: to move particles or mucus in a specific direction.
