Study Notes
Anatomy and Physiology
- Anatomy is the study of the structure of living organisms and their parts, including where organs are located.
- Physiology is the study of how parts function and why they work the way they do.
- Anatomy and physiology are related; anatomy describes where the heart is, while physiology explains how it pumps blood.
Organization of the Human Body
- The human body is organized in levels: atoms, molecules, cells, tissues, organs, organ systems, and organism.
- Atoms: basic units of matter
- Molecules: atoms chemically combined
- Cells: basic units of life
- Tissues: similar cells working together for a specific task.
- Organs: groups of tissues that perform a specific function (like the heart)
- Organ system: a group of organs functioning together (like the circulatory system)
- Organism: the entire body functioning as a whole
Homeostasis
- Homeostasis is a process that maintains stable internal conditions despite changes occurring outside the body (e.g., temperature, blood pressure).
- Example: The human body maintains a stable internal temperature of around 37°C, even when external temperatures change.
Negative Feedback
- Negative feedback is a process that keeps the body stable by fixing imbalances and bringing things back to normal.
- Example: If body temperature rises, sweating occurs to cool the body. If body temperature falls, shivering generates heat.
Positive Feedback
- Positive feedback makes a change in the body stronger and faster and pushes the process further in the same direction.
- Example: Childbirth - contractions of the uterus, release of oxytocin, stronger contractions until the baby is born.
Body Systems
- Systems work together to maintain homeostasis.
- Nervous system: Rapid communication between body parts.
Terminology of Position and Direction
- Anatomical position: Body erect, facing forward, arms at sides, palms forward.
-
Directional terms:
- Anterior/Ventral: front of the body
- Posterior/Dorsal: back of the body
- Superior/Cranial: toward the top
- Inferior/Caudal: toward the bottom
- Medial: toward the midline of the body
- Lateral: away from the midline
- Proximal: closer to the trunk
- Distal: farther from the trunk
Curiosities
- By old age, enough saliva will have been produced to fill more than one swimming pool.
- Humans lose more than 50 kg of dead skin cells during their lifetime.
