Details
What is a change or signal in the environment?
Stimulus
Name the type of digestion that occurs when food is physically being broken apart.
Mechanical Digestion
What are the two most common waste products?
water & urea
Which blood vessel has the highest pressure?
Artery
Describe how the systems are working together to carry out the process of cell respiration
The glucose is absorbed by the villi in the digestive system. The oxygen is taken in by the alveoli in the respiratory system. Carbon dioxide and water are removed by the alveoli in the respiratory system. ATP stays at the cells.
Name a type of chemical digestion
saliva in mouth, acid in stomach, pepsin in stomach
What is the role of the large intestine?
to absorb water
What two structures are the cite of exchange for filtration in the excretory system?
capillaries & nephrons
Which blood vessel is responsible for exchanging materials at the cells?
Capillary
What role are the capillaries involved with in the digestive system? Include what they are bringing in.
Role = absorption
Bringing in nutrients
Why is it crucial to have both chemical and mechanical digestion?
it makes the process of digestion more efficient
Which part of the blood helps to clot the blood?
platelets
Which nerves in the peripheral system control voluntary actions?
Somatic Nerves
The nervous system can be divided into two parts. Name them.
1) Central Nervous System
2) Peripheral Nervous System
Name a structure in the nervous system that has a lot of surface area that helps make a process more efficient.
Dendrites- make receiving information more efficient
Cerebrum- highly wrinkled allows for more neurons in brain to allow for faster receiving, interpreting, and responding of information
Describe how breathing works. (Two parts)
(1) Diaphragm moves (contracts/ relaxes) which causes (2) a change in pressure in the chest cavity
This lobe is in charge of personality, learning, remembering and other cognitive thought processes.
Frontal Lobe
This lobe is in charge of processing sensory information from your sense of touch
Parietal Lobe
What part of your blood is the liquid part that carries dissolved materials?
Plasma
Tell me how the structure of a structure in the circulatory system helps carry out its function
Arteries are built super thick to withstand the intense pressure near the heart.
Capillaries are super thin to allow for faster exchange of materials.
Veins have valves in them to keep low pressure blood from flowing backwards.
What is gas exchange?
O2 is diffuses from the alveoli to the capillaries and CO2 and H2O diffuse from the capillaries to the alveoli
How does the pathway of a reflex differ from the pathway of a typical nerve impulse?
The initial response in a reflex comes from the spinal cord
Describe the pathway of a typical nerve impulse. Use the words stimulus, receptors, sensory neuron, interneurons, spinal cord, brain, motor neurons, response
The receptors pick up a stimulus and send a nerve impulse on the sensory neuron to the interneuron in the spinal cord and brain. The brain interprets the information and determines a response. It sends the response back to the interneurons then to the motor neurons to carry out the response.
What does your temporal lobe process?
Auditory information
Describe how the circulatory, excretory, and nervous system help maintain homeostasis
The circulatory system fights disease. The excretory system keeps our bodies free from harmful levels of toxins/ waste. The nervous system responds appropriately to stimuli.
