brain, spinal cord, and muscles
In what way does the nervous system function as a two-way communication system in the body?
It has two vital organs: the brain and the spinal cord.
It has a brain that consists of two hemispheres: the left and the right hemisphere.

How is the respiratory system linked to the circulatory system?
The blood is made up of plasma, platelet, red blood cells, and white blood cells.
The blood carries carbon dioxide from the lungs ready for circulation around the body.
The oxygenated blood passes through the veins in going to the lungs and finally to the different body parts.
The deoxygenated blood collects oxygen during the exchange of gases which happens in the capillaries of the alveoli found in the lungs.

The digestive system digests food to be carried out by the respiratory system to the circulatory system as it provides oxygen to the digestive system.
The digestive system carries nutrients to the circulatory system, while the circulatory system digests food for the digestive system as it provides oxygen.
The digestive system works in parallel with the excretory system in the urination process. Discuss how it happens.
Digestion provides food to the body.
Complete digestion happens in the small intestine.
The digestive system sends sensory information to the brain.
The excretory system filters compound from the bloodstream and collect them in urine.

Nose → Trachea → Bronchiole
Nose →Trachea → Alveoli →Lungs →Diaphragm
Nose →Pharynx →Trachea →Bronchiole →Alveoli (lungs)
Nose →Pharynx →Trachea → Diaphragm →Alveoli (lungs)
In what ways does the nervous system function as a two-way communication system in the body?
It has two vital organs: The brain and the spinal cord.
It has a brain that consists of two hemispheres: the left and the right hemisphere.
The spinal cord contains bodies of nerve cells where messages to the brain pass through.
The brain receives messages through sensory nerves and sends messages through motor nerves.
How does the integumentary system work with the nervous system?
Motor nerves receive stimuli from the brain.
The nervous system coordinates body activities.
The brain controls the sweat glands of the body.
Nerves cells interpret messages from the sense organ.

How does the circulatory system works together with the respiratory system?
I- The circulatory system works directly with the respiratory system to provide oxygen to the body
II- The circulatory and respiratory systems work together to sustain the body with oxygen and to remove carbon dioxide.
III- Circulatory system carries the message to the respiratory system as it provides oxygen to the circulatory system.
