Study Notes
Overview of Organ Systems
- Organ systems are essential to maintain homeostasis, allowing the body to function optimally despite changes in the environment.
- Organs are collections of tissues working together for a common function.
- Each organ system includes interrelated organs that perform collective functions critical to survival.
Homeostasis
- Homeostasis refers to the body’s ability to maintain stable internal conditions (e.g., temperature) despite external fluctuations.
- Normal body temperature ranges from 36.5 to 37.5 degrees Celsius.
Organ Systems and Their Components
-
Nervous System
- Central Nervous System: Includes the brain (Cerebrum and Cerebellum) and spinal cord.
- Peripheral Nervous System: Composed of nerve cells and connections branching from the spinal cord.
-
Respiratory System
- Key components include the trachea, bronchioles, alveoli, pharynx, larynx, and lungs.
-
Endocrine System
- Key glands include testes, thyroid gland, pancreas, adrenal glands, pituitary gland, ovaries, parathyroid glands, and thymus.
-
Urinary System
- Important organs consist of kidneys, bladder, ureters, and urethra.
-
Cardiovascular System
- Main components include arteries, veins (e.g., superior and inferior vena cava), capillaries, blood, and the heart.
Illustrative Example
- The collaboration of the respiratory and cardiovascular systems ensures the distribution of oxygenated blood throughout the body.
- Regulatory mechanisms, such as sweating in response to heat, exemplify homeostasis in action.
