Study Notes
Animal Form and Function
- Anatomy is the biological form of an organism.
- Physiology is the biological function(s) an organism performs.
- Form and function are closely related.
- Size and shape affect how an animal interacts with its environment.
- The black-tailed jackrabbit lives in hot climates.
Diverse Forms, Common Challenges
- Black-tailed and white-tailed jackrabbits are closely related animals.
- Jackrabbits' size and shape affect their survival in different climates.
- The black-tailed jackrabbit inhabits hot climates.
Divergent and Convergent Evolution
- Divergent evolution occurs when two species diverge from a common ancestor.
- Convergent evolution leads to unrelated species developing similar structures with the same function.
- An example of convergent evolution includes birds, bats, and butterflies.
Exchange with the Environment
- Nutrients, waste products, and gases must pass through cell membranes.
- Exchange rate is proportional to a cell's surface area.
- The amount of exchange material is proportional to a cell's volume.
- Surface area increases faster than volume as an animal grows.
- Single-celled organisms in water have sufficient surface area for exchange.
- Multicellular organisms with thin body walls (e.g., a hydra) facilitate diffusion of materials.
- Larger, complex bodies enable animals to maintain stable internal environments.
Tissues
- Animals are composed of cells organized into tissues.
- Tissues consist of structurally and functionally similar cells and their intercellular material.
- Histology is the study of tissue types and functions.
Tissue Classification
- Tissues can be categorized based on their origin (ectodermal, endodermal, mesodermal).
- Tissues can also be classified based on cell composition (epithelial, endothelial, connective).
- Tissues can also be categorized based on organ systems (e.g., nervous tissue).
Epithelial Tissue
- This tissue covers the body's exterior and lines organs and cavities.
- Epithelial cells are closely joined.
- Epithelial cells can be cuboidal, columnar, or squamous.
- The arrangement of epithelial cells can be simple (single layer), stratified (multiple layers), or pseudostratified (a single layer with varying cell lengths).
Connective Tissue
- This tissue binds and supports other tissues.
- The matrix of connective tissue contains fibers in a liquid, jelly-like, or solid form.
- Types of connective tissue include loose connective tissue, fibrous connective tissue, adipose tissue, blood, bone, and cartilage.
- Blood is composed of blood cells and cell fragments in plasma.
- Bone forms the skeleton.
Muscle Tissue
- Responsible for body movement.
- Muscle cells contain actin and myosin filaments.
- Types of muscle tissue include skeletal (voluntary), smooth (involuntary), and cardiac (heart contraction).
Nervous Tissue
- Receives, processes, and transmits information (responds to stimuli).
- Nervous tissue contains neurons (nerve cells) and glial cells (support).
- Neurons transmit nerve impulses.
- Glial cells support nerve cells.
Organ Systems in Mammals
- Endocrine system coordinates body functions through hormones.
- Nervous system coordinates body functions through electrical signals.
- Musculoskeletal system supports and moves the body.
- Cardiovascular system transports substances throughout the body.
- Respiratory system facilitates gas exchange.
- Urinary system filters blood and eliminates wastes.
- Gastrointestinal system breaks down and absorbs nutrients.
- Reproductive system produces offspring.
- Immune system protects against pathogens.
- Integumentary system protects the body.
