Introduction to Anatomy & Physiology (Part 3)

Anatomical Planes:
- Frontal Plane: Divides the body into anterior and posterior sections.
- Midsagittal Plane: Divides the body into equal left and right halves.
- Sagittal Plane: Divides the body into left and right sections (not necessarily equal).
- Transverse Plane: Divides the body into superior and inferior sections.
Anatomical Position: The standard position for describing body parts.

Body Organization and Systems

Atomism: Atom → Molecule → Organelle → Cell → Organ → Organ System → Organism
Levels of Organization: Cells, tissues, organs, organ systems.
Human Organism → Organ System → Organs → Tissues
Major Systems (Functions):
- Integumentary: Protection, temperature regulation, water retention, sensation.
- Skeletal: Protection of body organs, support, movement, blood formation.
- Muscular: Movement, posture, heat production.
- Lymphatic: Fluid balance, immune cell production, defense against disease.
- Respiratory: Absorption of oxygen, discharge of carbon dioxide, acid-base balance, speech.
- Urinary: Excretion of wastes, regulation of blood volume and pressure, control of fluid, electrolytes, and acid-base balance.
- Nervous: Control, regulation, and coordination of other systems, sensation, memory.
- Endocrine: Hormone production, control and regulation of other systems.
- Circulatory: Circulation of oxygen, nutrients, wastes, hormones, electrolytes, immune cells, and antibodies, fluid, electrolyte, and acid-base balance.
- Digestive: Breakdown and absorption of nutrients, elimination of wastes.
- Reproductive (Female): Production of eggs, site of fertilization, fetal development, birth, lactation, sex hormone secretion.
- Reproductive (Male): Production and delivery of sperm, secretion of sex hormones.

Body Planes and Organization

Anatomical Position: The standard reference position when describing human anatomy.
Regions: Head, neck, torso/trunk, upper limb, and lower limb (More detailed regions of the body can be learned later).
Directional terms: Superior, inferior, anterior, posterior, medial, lateral, proximal, distal, superficial, and deep.
Body Cavities and Quadrants: A cavity is a hollow space within the body, and the body is further divided into various regions such as quadrants. (More detailed information about body quadrants and cavities will be covered later.)

Homeostasis(Chapter 2 Part 3)

Homeostasis: The dynamic equilibrium of the internal environment in the body.
Homeostatic Regulation (Involves):
- Receptor: Receives information about changes in the environment.
- Control Center: Receives and processes information from the receptor.
- Effector: Responds to signals from the control center. This response can oppose or enhance the stimulus to maintain a stable internal environment.
