Study Notes
Human Body Structures
- Carpal bones comprise the wrist.
- Pelvic bones consist of the fusion of ilium, ischium, and pubis.
- Patella is a specialized bone located anterior to the knee.
Central Nervous System Functionality
- Cerebellum coordinates bodily movements such as writing or sewing.
- The brain and spinal cord together form the central nervous system.
- Sensory nerves carry information from the body to the central nervous system.
Respiratory and Cardiac Physiology
- Cells generate large amounts of adenosine triphosphate (ATP) when functioning with adequate oxygen.
- The body's backup respiratory control system, responding to low blood oxygen levels, is known as hypoxic drive.
- A normal resting adult heart rate should not exceed 100 beats per minute; stroke volume ranges from 70 to 80 mL per heartbeat.
- Agonal respirations are ineffective and need assistance.
Blood Composition and Functions
- The spleen filters out worn-out blood cells, foreign substances, and bacteria.
- Capillaries are the site for the exchange of oxygen and nutrients for waste products at the cellular level.
- Aorta is the major artery supplying blood to all other arteries.
Anatomical and Physiological Concepts
- Signs of adequate adult breathing include 18 breaths per minute and bilateral clear breath sounds; a reduction in tidal volume is not a sign of adequacy.
- Diaphragm forms the inferior boundary of the thorax, separating it from the abdomen.
Health and Pathophysiology
- Pathophysiology examines functional changes in the body in response to disease.
- Accumulation of blood in the sac surrounding the heart leads to obstructive shock.
Additional Physiological Insights
- The brain stem coordinates all critical life functions.
- Myocardium refers to the muscle tissue of the heart.
- The skin performs various functions, excluding metabolic coordination.
