Study Notes
Levels of Organization
- Atoms combine to form molecules, which make up cells at the chemical and cellular levels.
- Tissues consist of similar types of cells and are organized into different types of tissues at the tissue level.
- Organs are formed from multiple tissue types and operate as part of organ systems.
- The organismal level encompasses all organ systems working together.
Organ Systems Overview
- Respiratory System:
- Maintains oxygen supply and carbon dioxide removal.
- Gaseous exchanges occur in the air sacs of the lungs.
- Digestive System:
- Includes mouth, esophagus, stomach, intestines, and accessory organs.
- Breaks down food, absorbs nutrients into the bloodstream, and eliminates waste material.
Necessary Life Functions
- Reproduction:
- Cellular level: Involves new cell production for growth and repair.
- Organismal level: Managed by the reproductive system.
- Growth:
- Results in increased cell or body size, regulated by hormones.
Survival Needs
- Nutrients:
- Essential for energy and cell structure; includes carbohydrates, proteins, lipids, vitamins, and minerals.
- Oxygen:
- Vital for chemical reactions, supplied by respiratory and cardiovascular systems.
- Water:
- Comprises 60-80% of body weight, vital for bodily functions and chemical reactions.
- Normal Body Temperature:
- Optimal at 37ºC (98.6ºF); deviations affect chemical reactions.
- Atmospheric Pressure:
- Necessary for effective gas exchange.
Language of Anatomy
- Specialized terminology clarifies position, direction, and structure to avoid misunderstandings.
- Anatomical Position:
- Standard position: Standing, arms at sides, palms facing forward.
Directional Terms
- Superior (cranial): Above or toward the head.
- Inferior (caudal): Below or toward the feet.
- Anterior (ventral): Front of the body.
- Posterior (dorsal): Back of the body.
- Medial: Toward the midline.
- Lateral: Away from the midline.
- Proximal: Closer to point of attachment or body trunk.
- Distal: Farther from point of attachment or body trunk.
- Superficial (external): Towards the body surface.
- Deep (internal): Away from the body surface.
Regional Terms
- Divides the body into anatomical landmarks for reference.
Body Cavities
- Two main cavities:
- Dorsal: Contains cranial (brain) and spinal (spinal cord) cavities, protected by skull and vertebrae.
- Ventral: Contains thoracic and abdominopelvic cavities, separated by the diaphragm.
Protection of Organs
- Body cavities provide varying degrees of protection to the organs contained within.
