Study Notes

Animal Tissues and Systems

Muscular Tissue:
- Involuntary muscles like cardiac muscle in the heart.
- Skeletal muscles (not in notes) for voluntary movement.
- Smooth muscles found in internal organs (not detailed).
Skin (Dermis):
- Composed of muscle, nervous, and connective tissues.
- Protects from damage, insulates, and releases waste/heat.
- Made of epidermis and dermis layers.

Plant Tissues

4 Types of Plant Tissues:
- Meristematic Tissue: Unspecialized, capable of differentiation.
- Epidermal Tissue: Outer layer of leaves, thin and clear, with guard cells controlling stomata.
- Vascular Tissue: Transports water and nutrients.
  - Xylem: Transports water and minerals from roots to leaves.
  - Phloem: Transports sugars from leaves to other parts.
- Ground Tissue: Makes up most of the plant.
  - Found in roots (food and water storage).
  - Leaves (photosynthesis and gas exchange, in mesophyll).

Respiratory System

Organs: Nose, mouth, trachea, bronchi, lungs.
Trachea: Splits into bronchi, which branch into bronchioles, ending in alveoli (air sacs).
Alveoli: Tiny air sacs with thin walls for gas exchange with capillaries.
Epithelial Cells: Line trachea and bronchi, producing mucus and having cilia to trap particles.
Inspiration: Diaphragm contracts, rib cage expands, decreasing lung pressure causing air intake.
Expiration: Diaphragm and intercostal muscles relax, increasing lung pressure and expelling air.
Gas Exchange: Oxygen and carbon dioxide diffuse across thin alveolar and capillary walls.

Digestive System

Processes: Ingestion, digestion, absorption, egestion.
Esophagus: Muscular tube for swallowing, using peristalsis.
Stomach: Breaks down food with enzymes and acid.
Small Intestine: Primarily site of digestion; villi increase surface area for absorption.
Large Intestine: Absorbs water; egests indigestible materials.

Circulatory System

Components: Blood (cells, plasma), heart (4 chambers), blood vessels (arteries, veins, capillaries).
Heart Chambers:
- Atria: Receive blood from veins and pump it to ventricles.
- Ventricles: Pump blood to body (left) or lungs (right).
Blood Vessels:
- Arteries: Carry oxygenated blood away from the heart.
- Capillaries: Thin-walled vessels for exchange with cells.
- Veins: Carry deoxygenated blood back to the heart.
- Vena Cava: Major veins returning blood to the heart.
Heart Function: Pumps blood, keeping it flowing through body, lungs, and heart.
Blood Circulation: Deoxygenated blood -> heart -> lungs -> oxygenated blood -> heart -> body.
Circulatory support: Protective layer surrounds the heart (pericardium) and nervous/ connective tissue in heart to support its function, and blood vessels to supply the heart.
