Study Notes

Cell Structure and Function

Cells are the basic units of structure and function in organisms.
Some organisms, like bacteria and protists, are unicellular, meaning they are made entirely of one cell.

Epithelial Cells

Three different shapes of cells are encountered in the epithelium.

Types of Body Tissues

7 types of body tissues:
- Bone
- Cartilage
- Ligaments, tendons, and facial sheath
- Areola tissue
- Adipose (Fat) tissue
- Blood
- Nervous tissue

Organ Systems

10 organ systems in the human body:
1. Nervous System
- Collecting, transferring, and processing information with the brain, spinal cord, and nerves.
2. Reproductive System
- Consists of sex organs, including ovaries, fallopian tubes, uterus, vulva, vagina, testes, vas deferens, seminal vesicles, prostate, and penis.
3. Respiratory System
- Organs used for breathing, including the pharynx, larynx, trachea, bronchi, lungs, and diaphragm.
4. Skeletal System
- Provides structural support and protection with bones, cartilage, ligaments, and tendons.
