Respiratory
What is the function of the lungs in the respiratory system?
To facilitate gas exchange between the blood and the environment.
What is the function of the heart in the cardiovascular system?
The heart pumps blood throughout the body through the arteries and capillaries.
What is the function of the brain in the nervous system?
The brain controls the sending of electrical impulses through the nerves to control all processes in the body.
What is the function of muscles in the body?
Muscles contract and expand, allowing for movement in the body.
What is the function of the bones in the body?
The bones provide structure for the body and protect internal organs.
Where in the lungs does gas exchange with the blood occur?
Gas exchange in the lungs occurs in the alveoli.
How does the cardiovascular system interact with the digestive system?
It absorbs nutrients from the digestive system and distributes them throughout the body.
How does the nervous system impact the endocrine system?
The nervous system sends signals to the glands in the endocrine system to produce hormones.
How do muscles interact with bones?
Muscles are connnected to bones by tendons, which are what allow the muscle to expand and contract.
How does the skeletal system interact with the cardiovascular system?
The bones produce white blood cells in the marrow, which is then transported to the blood to protect the body.
How does the respiratory system respond to the need for more oxygen signaled by the nervous system?
The respiratory system works faster, leading to rapid breathing.
How does the cardiovascular system interact with the excretory system?
The blood enters through the kidneys, where urea and excess water is filtered out.
How does the nervous system respond to external stimuli on the skin?
The nervous system has many types of receptors in the skin which send unique electrical signals to the brain when triggered.
How do muscles respond to increased blood flow?
The muscles produce more energy due to more nutrients and oxygen being recieved, and waste products (lactic acid/CO2) are removed
What occurs to the nervous system when a bone is fractured?
The impairment of function leads to pain receptors being triggered. This leads to intense pain being felt.
What is the valve which prevents food going down the esophagus from entering the trachea when food is being digested?
The epiglottis is the valve which prevents food from entering the trachea.
How do the pulmonary veins interact with the lungs and heart?
The pulmonary veins return oxygenated blood back to the heart from the lungs to be pumped throughout the rest of the body.
How does the nervous system interact with the excretory system?
The nervous system controls the rate of kidney filtration, is responsible for maintaining equilibrium of fluids in the blood, and signaling necessary movements for the excretion of urine.
When deprived of oxygen, what do the muscles signal to the brain, and what is the result?
The muscles produce lactic acid, signaling stress to the brain, which sends signals to cause exhaustion and increase heart rate.
How do the vertebrae interact with the nerves in the spinal cord?
The vertebrae protect the nerves in the spinal cord from damage.
How do the digestive system and the respiratory system interact with each other?
The digestive system provides cells with glucose while the respiratory system provides the cells with oxygen, and this allows for cellular respiration to occur.
How does the cardiovascular system interact with the endocrine system?
The cardiovascular system uses the blood to transport hormones throughout the body for specific purposes.
What are the two different types of nervous systems, and how do they differ in controlling the body?
The Central Nervous System and the Periphereal Nervous System are the two types of nervous systems. The CNS serves as a control center by which the PNS completes tasks dictated by it throughout the body.
How do muscles interact with the endocrine system?
How does the skeletal system impact the digestive system?
The skeletal system impacts the digestive system by allowing for mechanical digestion in the mouth.
