Study Notes
Introduction to Lab Science, Chemistry, Organs, Systems, and Organization of the Body
- The material covers lab science, chemistry, organs, systems, and the anatomy and physiology of the human body.
- The information is based on Seeley's Anatomy and Physiology and Seeley's Anatomy and Physiology Laboratory Manual by Eric Wise.
- The presenter is Roland Oswald A. Banta, RMT, MD, a general physician and program head at the College of Medical Technology.
Introduction to Anatomy and Physiology
- Science is the study of physical phenomena with specific guidelines.
- Human body structure and function fall within scientific investigation.
- Human anatomy studies structure, while human physiology studies function.
Introduction to Anatomy and Physiology
- Scientific understanding often begins with a question.
- An example question is how the body digests food.
- Developing a testable proposal (hypothesis) to answer the question.
- Hypothesis testing is often performed through experiments.
Introduction to Anatomy and Physiology
- Much of science involves measuring and collecting data.
- Experimental data (facts) are collected and examined to support or reject hypotheses.
Introduction to Anatomy and Physiology
- Studying the human body requires understanding how body parts are oriented and presented in body regions.
- The lecture covers major organ systems.
- Directional terms are studied, alongside organizational levels ranging from subatomic to organism level.
- Also, the major body regions need to be described.
Levels of Organization
- The human body can be studied from various viewpoints.
- Gross anatomy (dissection) was an early method.
- Advancements in equipment led to deeper levels of understanding body organization.
- Modern imaging tools like MRI allow for studying structures without dissection.
Levels of Organization
- The images illustrate different organizational levels such as chemical, organelle, cell, tissue, organ, organ system, and organism.
Organ Systems
- Anatomy can be studied regionally (head, leg) or systematically (organ systems).
- Systemic anatomy studies organ systems like the skeletal or nervous systems.
- Studying different organ systems separately is important, but realizing their connections is also crucial.
Organ Systems
- Organ systems are interconnected.
- The failure of one system can affect others.
- An example is how a failing heart affects the lungs, intestines, and brain, leading potentially to death.
Organs of the Body
- The image provided illustrates the location of major organs within the body. Examples of organs include: Brain/Spinal cord, Lungs, Liver, Stomach, Spleen, Kidney, Small intestine, Large intestine, Urinary bladder.
The Reproductive System
- The reproductive system ensures species survival.
- Male and female reproductive organs work together and produce offspring.
- The main reproductive organs are ovaries, uterine tubes, uterus, vagina (female); testes, ductus deferens, seminal glands, and penis (male).
Male/Female Reproductive Systems
- The diagrams show the key organs of the male and female reproductive systems in different views.
- Descriptions are provided about each sex’s reproductive process and function.
The Lymphatic System
- The lymphatic system cleanses bodily fluid (returning it to the cardiovascular system) and protects against foreign entities.
- The lymphatic system is part of the immune system.
- This system includes lymph vessels and organs such as the thymus, spleen, and tonsils.
The Urinary System
- The urinary system eliminates waste products.
- It includes kidneys, ureters, urinary bladder, and urethra.
- This system regulates blood pH, water balance, and ion balance.
The Integumentary System
- The integumentary system is the body’s protective outer layer, primarily skin, also including hair, nails, sweat glands, and sebaceous glands.
- Its responsibilities include protection, temperature regulation, water retention, and vitamin D synthesis.
The Nervous System
- The human nervous system is complex, allowing for interactions and interpretation of the environment through the brain, spinal cord, and nerves.
- The nervous system plays key roles in detecting sensations, controlling movements, physiological processes, and intellectual functions.
The Digestive System
- The digestive system processes food.
- The mouth, salivary glands, esophagus, stomach, intestines, liver, and associated organs (gallbladder, pancreas) are part of this system.
- This system mechanically and chemically digests food, absorbs nutrients, and eliminates waste.
The Muscular System
- The muscular system facilitates bodily movements.
- This system includes individual muscles like biceps brachii and gluteus maximus muscles.
- Muscle contractions generate movement and maintain posture.
The Endocrine System
- The endocrine system generates hormones to control multiple bodily functions including metabolism, growth, reproduction, amongst other roles.
- Endocrine organs include hypothalamus, pituitary, thyroid, pancreas, and gonads.
The Respiratory System
- The respiratory system supplies oxygen and removes carbon dioxide.
- The nose, pharynx, larynx, trachea, and lungs form parts of the respiratory system.
- Maintaining blood pH and proper air flow are essential functions carried out by the respiratory system.
The Cardiovascular System
- The cardiovascular system is primarily a transport system.
- The heart and blood vessels deliver vital nutrients and remove waste products throughout the body.
- This system also plays a role in regulating temperature and immune responses.
The Skeletal System
- The skeletal system provides a framework for movement and protect internal organs in the body.
- The skeletal system consists of individual bones like the humerus and femur.
- These provide structural support, movement, blood cell production, and minerals/fat storage.
The Anatomical Position
- The anatomical position is a standardized reference point for describing human body structures.
- The body is upright, facing forward, arms and legs straight, palms forward.
Body Planes
- Sagittal, Median, Transverse (horizontal), and Frontal planes are ways to view the body from different perspectives for anatomical descriptions.
Major Body Cavities
- A cavity is an enclosed space within the body.
- The major body cavities are cranial, vertebral, thoracic, abdominal, and pelvic.
- These cavities house and protect vital organ systems.
Major Body Cavities
- Structures such as the heart, esophagus, and trachea are located within the mediastinum which lies within the thoracic cavity, which is above the abdominal cavity.
- The pleural cavities and the abdominal cavity contains organs such as the stomach and intestines.
- The pelvic cavity contains the lower intestines and reproductive structures within the female body.
Body Regions
- Body regions are specific areas of the human body for anatomical descriptions.
- Upper limb regions (arm, forearm, wrist, hand).
- Lower limb regions (thigh, lower leg, ankle, foot).
- Central region regions (head, neck, trunk).
Abdominal Regions/Quadrants
- The abdomen is divided into regions and quadrants for easier location of abdominal organs.
