What is the role of the heart in the circulatory system?
The heart produces hormones for digestion.
The heart filters toxins from the blood.
The heart's role is to pump blood, facilitating circulation of oxygen and nutrients.
The heart stores excess nutrients for later use.
Which blood vessels carry blood away from the heart?
Arteries
Capillaries
Veins
Venules
What is the primary function of the lungs?
The primary function of the lungs is gas exchange.
Regulating body temperature
Filtering dust from the air
Breathing in oxygen only
How do we breathe in air?
We breathe in air by inflating our cheeks and holding our breath.
We breathe in air by contracting the diaphragm and expanding the chest cavity, which creates a vacuum that pulls air into the lungs.
Air enters the lungs through the skin when we are outside.
We breathe in air by swallowing it directly into the stomach.
What part of the nervous system controls voluntary actions?
Autonomic nervous system
Central nervous system
Peripheral nervous system
Somatic nervous system
What is the basic unit of the nervous system?
Neuron
Axon
Dendrite
Synapse
Which system is responsible for movement in the body?
Skeletal system
Digestive system
Nervous system
Muscular system
What are muscles made of?
Muscles are made of fat cells and carbohydrates.
Muscles consist of only water and minerals.
Muscles are made of muscle fibers, proteins (actin and myosin), connective tissue, blood vessels, and nerves.
Muscles are composed of skin and hair.
What is the function of the small intestine?
The function of the small intestine is to digest food and absorb nutrients.
To store bile for fat digestion.
To produce insulin for blood sugar regulation.
To filter toxins from the blood.
What type of blood do veins carry?
Deoxygenated blood (except pulmonary veins which carry oxygenated blood)
Oxygenated blood
Nutrient-rich blood
Carbon dioxide-rich blood
What is the diaphragm's role in respiration?
The diaphragm helps in digestion by moving food through the esophagus.
The diaphragm's primary function is to support the spine during physical activity.
The diaphragm's role in respiration is to facilitate inhalation and exhalation by changing the volume of the thoracic cavity.
The diaphragm regulates blood pressure by controlling heart rate.

Heart
Lungs
What is the largest muscle in the human body?
gluteus maximus
trapezius
rectus femoris
biceps brachii
What is the function of red blood cells?
Regulate body temperature.
Fight infections and diseases.
Transport oxygen and carbon dioxide in the body.
Store nutrients in the body.
How does oxygen enter the bloodstream?
Oxygen is absorbed through the skin.
Oxygen enters the bloodstream via the stomach.
Oxygen is transported by red blood cells from the liver.
Oxygen enters the bloodstream through the alveoli in the lungs.
What is the role of the stomach in digestion?
The stomach is primarily responsible for producing bile.
The stomach absorbs nutrients directly into the bloodstream.
The stomach filters toxins from the food before digestion.
The stomach mixes food with gastric juices to break it down for nutrient absorption.
What type of muscle is found in the heart?
Cardiac muscle
Striated muscle
Skeletal muscle
Smooth muscle
What is the function of the spinal cord?
The spinal cord produces hormones for the body.
The spinal cord filters toxins from the blood.
The spinal cord transmits signals between the brain and the body, and coordinates reflexes and motor control.
The spinal cord is responsible for digestion and metabolism.
