Study Notes
Organ Systems Overview
- The digestive system includes the oral cavity, esophagus, stomach, small and large intestines, and accessory organs, and breaks down food for nutrient absorption into the blood.
- The urinary/renal system includes the kidneys, ureters, urinary bladder, and urethra, and eliminates nitrogenous wastes, maintains acid-base balance, and regulates water and electrolytes.
- The reproductive system includes organs responsible for producing sex cells and supporting the development of a fetus during pregnancy.
- The cardiovascular system includes the heart and blood vessels, and transports materials in the body via blood pumped by the heart.
- The lymphatic system includes lymphatic vessels, lymph nodes, and lymphoid organs, and returns leaked fluids back to blood vessels, cleanses the blood, and is involved in immunity.
- The respiratory system includes the nasal passages, pharynx, larynx, trachea, bronchi, and lungs, and supplies blood with oxygen and removes carbon dioxide.
Body Cavities and Regions
- The body has two main cavities: the dorsal body cavity and the ventral body cavity.
- The dorsal body cavity includes the cranial cavity and the spinal cavity.
- The ventral body cavity includes the thoracic cavity, the abdominal cavity, and the pelvic cavity.
- The body can be divided into several regions, including the cephalic, occipital, acromial, cervical, brachial, olecranal, back, antebrachial, scapular, vertebral, lumbar, sacral, gluteal, digital, femoral, popliteal, sural, pedal, and calcaneal regions.
Anatomy and Physiology
- Anatomy is the study of the structure and organization of living things.
- Physiology is the study of the functions and processes that occur within living things.
- The levels of structural organization in the human body include the chemical, cellular, tissue, organ, and organ system levels.
- The necessary life functions include nutrition, metabolism, respiration, circulation, excretion, and reproduction.
- Homeostasis is the ability of the body to maintain a stable internal environment despite changes in the external environment.
- Feedback mechanisms help maintain homeostasis, and can be negative or positive.
Anatomical Position and Directional Terms
- The anatomical position is a standard body position that helps describe the location of body structures.
- Common directional terms include anterior, posterior, superior, inferior, medial, lateral, proximal, and distal.
- Body planes and sections include the median, frontal, and transverse planes.
- Regional terms are used to describe specific areas of the body.
