Endocrine System
What is the sugar our body uses to create energy during cellular respiration
glucose
This is another name of any foreign invader of a human's body
Receptors are all different from one another based on their ___________ shape they require with antigens they bind to
specific
Name an organ of the nervous system
brain/spinal cord
This is another phrase for Homeostasis
Dynamic Equilibrium
Where do humans get glucose from and for what process is it needed?
glucose we get from our food and it travels in our blood to allow for cellular respiration
These types of cells create antibodies to fight off pathogens
white blood cells
the chemical messenger in the nervous system that travels across the synapse of neurons that will find a specific receptor is known as....
a neurotransmitter
endocrine- not making enough insulin or too much
nervous- brain issues
Respiratory- not enough O2
Circulatory-blood not getting around body
muscular- cramps
This type of feedback bring you back to homeostasis.(ex: When your body when it is very warm it cools itself back down by sweating)
what is one likely reason that an individual might have a sustained spike in blood glucose levels
antibodies tag and destroy pathogens by attaching to what parts of the pathogens?
the antigens
Which substance may form in the human body due to invaders entering the blood?
antibodies
Why are fevers for long periods of time not healthy? What specifically happens inside of your body to cause you to possibly die(and things to not work...)
The shape specific molecules such as proteins, enzymes, antibodies, and other receptors can denature, causing them to not work
white blood cells are most closely associated with which two body systems?
circulatory and immune systems
What organ of the body will create insulin and what does this hormone do?
insulin is created in the pancreas and its job is to lower blood glucose levels when they get too high.
HIV/AIDS does not directly kill patients who contract the disease because...
Name three types of molecules that depend on a specific shape to function
hormones, neurotransmitters, proteins, enzymes, antibodies
What is inside of a influenza Vaccine?
a dead/weakened version of a influenza(the flu)
Name two body systems and explain how they work together to help maintain homeostasis in the body
Examples: 1.)Nervous systems tells the muscular system to move its muscles and allow for movement.
2.)The digestive system breaks down food and prepares for cellular respiration, while the excretory system gets rid of the wastes afterwards
3.)The nervous system tells respiratory system to take in oxygen in the lungs to allow respiration to occur during exercise.
Describe a negative feedback mechanism of insulin use in the human body after exercise AND after eating candy.
As exercise increases, blood sugar decreases and the body will inhibit insulin As blood sugar increases from eating candy, insulin secretion will increase.
HIV/AIDS attacks a person's immune system very quickly and scientists have known about the disease for many years. Scientists have yet to develop a working vaccine or cure that can be used for long periods of time for HIV or AIDS because the HIV/AIDS virus does this.
constantly mutates, so that the shape of the antigens on its surface change shape so that it cannot be tagged or identified by antibodies
Antihistamines are drugs that can inhibit the active site of histamine receptors in the human body. Histamine molecules trigger an allergic reaction by binding to histamine receptor. When Antihistamines are given to a patient, they do not get allergies. What about antihistamines makes this possible?
Antihistamine molecules have the same shape as histamine molecules, and they will block the histamine receptors to prevent the body from triggering the allergic reaction.
Name two parts of a neuron and give us their function
Axon- carries the electrical message
Dendrites-receive the message
Terminal branches- where the message is converted into a neurotransmitter
Nucleus- contains the genetic instructions
Neurotransmiter- Chemmical message that crosses the synapse(gap) between two neurons
What is an example of positive feedback?
Childbirth
