Study Notes

Systems of the Body

Nervous system: Manages rapid body responses, controls higher functions like consciousness, memory, and creativity. Primary component is the neuron. Responds to acute/immediate body challenges and is important for diseases like cerebral palsy, sport performance (movement control).
Endocrine system: Regulates long-term processes like metabolic activities and water/electrolyte balance using hormones.
Respiratory system: Obtains oxygen and eliminates carbon dioxide, regulates blood pH by adjusting carbon dioxide removal.
Circulatory system: Transports nutrients, oxygen, carbon dioxide, waste, electrolytes, and hormones throughout the body.
Integumentary system: Acts as a protective barrier, including sweat glands, and adjusts skin blood flow for temperature regulation.
Muscular system: Enables movement and generates heat through muscle contractions. Important for temperature regulation. Primary component is muscle fiber.
Skeletal system: Supports and protects body parts, stores calcium. Primary component is minerals and cells. Osteoporosis is a serious disease.
Immune system: Protects against foreign invaders and tumors, assists with tissue repair. Components are physical, mechanical, chemical, blood, and cellular factors.
Energy system: Provides energy for life processes through aerobic and anaerobic pathways, essential for all cells.
Digestive system: Extracts nutrients, water, and electrolytes from food and transfers them to the bloodstream. Eliminates undigested material. Primary component is the gastrointestinal tract. Factors like gastric emptying rate influence glucose absorption.
Urinary system: Regulates fluid volume, electrolyte composition, and blood pH, removes waste products. Primary component is the kidney. Hypertension can be affected by kidney function.
Reproductive system: Essential for species continuation, not necessary for homeostasis.

Nervous System

Primary functions: Control systems of the body, thought processes.
Primary component: Neuron
Responsiveness: Acute/immediate body challenges.
Considerations: Disease conditions (e.g., cerebral palsy), sport performance (e.g., controlling movement).

Nervous System details

Central Nervous System: Brain and spinal cord
Peripheral Nervous System: Sensory and Motor
Autonomic Nervous System: Parasympathetic and Sympathetic (Smooth muscle, Cardiac muscle, Glands)
Somatic Nervous system: Motor neurons (Skeletal muscle),

Muscular System

Primary functions: Movement, body position stabilization, organ contraction.
Primary component: Muscle fiber
Types of muscle: Skeletal, cardiac, smooth.

Skeletal System

Primary functions: Structural framework, protection of organs and tissues, lever system for movement, mineral storage.
Primary component: Minerals and cells.
Condition: Osteoporosis is a severe disease.

Cardiovascular System

Primary functions: Transports oxygen, nutrients, hormones, electrolytes, drugs. Removes waste products.
Primary component: Heart, blood vessels, blood.
Important note: Cardiovascular disease is a leading cause of death.
Atherosclerosis: Fatty buildup in artery walls, decreased blood flow, clot formation.

Pulmonary System

Primary functions: Moving air into and out of the lungs, regulating acid-base balance.
Primary component: Lung.
Important factor: Exhaling carbon dioxide regulates blood pH, essential during exercise.

Urinary System

Primary functions: Eliminating waste products, regulating fluid volume, electrolyte composition, and blood pH.
Primary component: Kidney.
Associated disease: Hypertension.

Digestive System

Primary functions: Nutrient and water transfer from food into the body.
Primary component: Gastrointestinal tract.
Important note: Gastric emptying rate affects glucose absorption during exercise (6-8% solution).

Endocrine System

Primary function: Regulates physiologic function and body systems by producing and releasing hormones from endocrine glands.
Primary components: Endocrine glands (e.g., pituitary, thyroid, parathyroid, adrenal, pancreas, testis, ovary).
Associated condition: Insulin resistance can lead to metabolic syndrome.

Immune System

Primary function: Regulates the body's susceptibility, severity of infections, and recovery from illness.
Primary components: Physical, mechanical, chemical, blood, and cellular factors.
Exercise relationship: Regular exercise can improve immune function and decrease the risk of certain diseases.

Energy System

Primary functions: Provides energy during rest and exercise.
Primary components: Enzymes and energy sources within cells.
Importance: Energy production is crucial for successful athletic performance of varying intensities and durations.
Energy systems (ATP-PC, Glycolysis, Oxidative): Different energy systems are utilized depending on duration and intensity of activity.
