Study Notes

Animal Tissues

Animal tissues are similar to plant tissues, with different types of tissues performing different functions.
There are different kinds of tissues in animals to perform different functions, such as:
- Covering and protecting the body
- Helping in movement (performed by muscles and bones)
- Making connections between tissues
- Carrying information (responses)

Organ Systems

Different organ systems work together to carry out different functions, including: (No answers provided, but examples of organ systems include nervous, circulatory, respiratory, etc.)

Tissue Identification

To identify tissues, a microscope and specific procedures are necessary.
Procedures for observing epithelial tissue, blood, and muscle tissue are described, including the use of dilute HCl, forceps, and a microscope.

Epithelial Tissue

Epithelial tissue is present in the skin, lining of mouth, lining of blood vessels, lung alveoli, and kidney tubules.
The name "epithelial" comes from the Greek words "epi" meaning "outer" and "thelium" meaning "tissue".
Epithelial tissue cells are arranged in a continuous sheath, with no intercellular space.
This tissue provides protection to the inside and outside of the animal body.

Blood Tissue

Blood is a type of tissue that is composed of different cells and a fluid-like substance.
Blood cells are not all the same and are arranged in a specific way.

Muscle Tissue

Muscle tissue is composed of cells that are arranged in a specific way, with differences between skin cells and muscle cells.
Muscle tissue helps in movement.
