Study Notes
Digestive System
- Mechanical digestion occurs through the movement of food through the esophagus via peristalsis.
- The gallbladder plays a crucial role in emulsifying fats to aid in their digestion and absorption after consuming a meal high in fat content.
- The digestive system is pivotal for efficiently breaking down available food resources for nutrient absorption and energy production, ensuring sustenance and long-term survival.
Endocrine System
- The adrenal gland produces adrenaline, a hormone involved in the "fight or flight" response.
- When parathyroid hormone (PTH) is released, blood calcium levels increase.
- Testosterone is responsible for the development and maintenance of male secondary sexual characteristics.
- In females, estrogen is responsible for the development of secondary sexual characteristics, regulation of the menstrual cycle, and maintenance of pregnancy.
- Melatonin, produced by the pineal gland, plays a crucial role in regulating sleep-wake cycles.
- The anterior pituitary releases hormones in response to signals from the hypothalamus.
- The endocrine system is primarily responsible for regulating blood sugar levels, including the response to increased levels after a meal.
Muscular System
- Shivering to generate heat and maintain body temperature is primarily controlled by the muscular system through thermoregulation process.
Lymphatic System
- The lymphatic system is primarily responsible for the immune response, including the development of a fever in response to an infection.
Respiratory System
- The primary stimulus for increasing the rate and depth of breathing during exercise is the decreased blood carbon dioxide levels.
- During expiration, the diaphragm relaxes and moves superiorly, causing the volume of the thoracic cavity to decrease.
Excretory System
- Kidney failure impacts the excretory system by impairing the kidneys' ability to filter waste products from the bloodstream.
- Water aids in the elimination of metabolic wastes through urine, thus contributing to proper kidney function within the excretory system.
- The functions of the urinary system are regulation of blood pressure, blood pH, and removal of metabolic wastes from the body.
- The excretory system contributes to the maintenance of homeostasis in the body by removing metabolic wastes and toxins from the bloodstream.
Circulatory System
- The average adult human's resting heart rate typically falls within the range of 60-80 beats per minute.
- In a marathon race under scorching temperatures, the crucial aspect of the circulatory system is transporting oxygen to sustain muscle function.
Nervous System
- Neurons are categorized by sensory, motor, and interneuron based on their functions in transmitting signals within the nervous system.
- When a person experiences a sudden sensory perception of pain, the primary mediator of this sensory input is a neuron.
- Damage to the cerebellum would most likely result in impaired coordination and balance.
- The main function of the nervous system is the coordination of voluntary and involuntary actions.
- The nervous system is responsible for the rapid reflexive action of withdrawing the hand after touching a hot stove.
