Digestive
This "J-shaped" pouch stores, churns, and physically breaks down food
The Stomach
This structure is the main passageway that carries air from the nose and mouth to the lungs.
What is the trachea?
This tissue connects muscle to bone.
What is a tendon?
During intense exercise, muscles require more of this gas.
What is Oxygen?
Two students eat the same meal. One immediately exercises while the other rests. Explain how the digestive, respiratory, and muscular systems would function differently in each student.
The exercising student requires greater oxygen delivery and nutrient use by muscles, leading to increased respiration and energy production. The resting student has lower energy demands and slower nutrient utilization.
This enzyme in your saliva initiates the chemical breakdown of carbohydrates.
What is amylase?
This muscle contracts and moves downward during inhalation.
What is the diaphragm?
The primary function of muscles is to produce this.
What is movement?
This body system works closely with the respiratory system to transport oxygen.
What is the circulatory system?
A student has damage to the villi in their small intestine. Predict how this could affect their muscular system during exercise.
Reduced nutrient absorption would mean less glucose and other nutrients are available for muscle cells, leading to decreased energy production and earlier fatigue.
This enzyme requires the highly acidic environment of the stomach to break down proteins into smaller polypeptide chains.
what is pepsin
Oxygen enters the blood because its concentration is higher here than in the blood.
Where are the alveoli?
Name the three types of muscle tissue found in the human body.
What are skeletal, smooth, and cardiac muscles?
This digestive disorder is characterized by painful inflammation and ulcerations throughout the small and large intestines.
What is Crohn's disease?
A student runs a 5 km race after eating breakfast. Describe how the digestive, respiratory, and muscular systems work together.
The digestive system breaks down food and absorbs nutrients, the respiratory system supplies oxygen, and the muscles use both glucose and oxygen to produce energy for movement.
This fluid is produced by the liver, stored in the gallbladder, and emulsifies fats.
What is bile
These blood vessels surround alveoli and allow gas exchange.
What are capillaries?
This body system delivers oxygen and nutrients to muscles.
What is the circulatory system?
This movement decreases the angle of a joint.
What is flexion?
During intense exercise, muscle fatigue occurs. Explain how the digestive and respiratory systems help delay fatigue.
The digestive system provides nutrients for energy production, while the respiratory system delivers oxygen and removes carbon dioxide, helping muscles continue functioning efficiently.
The liver converts excess glucose into this complex carbohydrate for storage
What is glycogen?
Explain why air moves into the lungs during inhalation.
What is because lung pressure becomes lower than atmospheric pressure?
This connective tissue surrounds and protects an entire muscle.
What is fascia?
Explain how the respiratory and muscular systems work together during exercise.
What is the respiratory system supplies oxygen and removes carbon dioxide while muscles use oxygen to produce energy for movement?
Which system would have the greatest immediate impact on muscle function if it suddenly stopped working: digestive or respiratory? Explain.
The respiratory system would have the most immediate effect because muscles require a continuous oxygen supply. Digestive system disruptions would typically affect performance over a longer period.
