|
Respiratory System |
-Helps you breathe by letting out CO2 and bringing in oxygen |
|
|
Cilia |
Nose hairs that trap dirt and dust |
|
|
Trachea |
Carries Oxygen to the bronchi |
|
|
Bronchi |
Two tubes that divide into the lungs |
|
|
Lungs |
Made up of tiny air sacs called alveoli |
|
|
Alveoli |
Small air sacs in the lungs that absorb oxygen and release carbon dioxide. Capillaries surround each sac and exchange the gases there. |
|
|
Excretory System |
-Eliminates undigested solids and liquids and any waste created by the respiratory system -Eliminates oil and sweat created by the dermis and epidermis. |
|
|
Urinary tract |
Eliminates liquid waste |
|
|
What makes urine samples so important to doctors? |
-It can show signs if dehydration based on the color -It can help them tell if you have certain infections and diseases -It can help them tell if a disease is improving in a patient |
|
|
Urea |
Ingredient in urine, waste product made from the synthesis of protein |
|
|

|
|
Anus |
Excretes waste such as urine and solid waste |
|
|
Bladder |
Where urine is stored before it is excreted by the anus |
|
|
Where is urine produced? |
The kidneys, where it is stored in the bladder, secreted to the urethra then excreted by the anus |
|
|
Nervous System |
System where neurons relay messages about the outside world to the brain. It is made up of the PNS and CNS. |
|
|
PNS |
Peripheral Nervous System All nerves that are not a part of the CNS |
|
|
CNS |
Central Nervous System Consists of the spinal cord and brain |
|
|
Sensory neurons |
Neurons that pick up information from stimuli outside the body and relay it to the interneurons |
|
|
Interneurons |
Neurons that travel from the sensory neurons to the brain and motor neurons |
|
|
Interneurons |
Neurons that travel from the sensory neurons to the brain and motor neurons |
|
|
Motor neurons |
Neurons that control movement |
|
|
Describe the path of neurons |
A sensory neuron would tell am interneuron about the stimulus, then the interneuron would relay the information to a motor neuron that could control movement |
|
|
Immune System |
System that fights off pathogens and helps the body maintain homeostasis |
|
|
Immune System |
System that fights off pathogens and helps the body maintain homeostasis |
|
|
T Cells |
Identify pathogens so other WBCs can help fight it |
|
|
Immune System |
System that fights off pathogens and helps the body maintain homeostasis |
|
|
T Cells |
Identify pathogens so other WBCs can help fight it |
|
|
B cells |
Provide an antigen that locks onto the pathogen, immobilizing it |
|
|
Phagocytes |
WBCs that fight the immobilized pathogen |
|
|
Explain how the WBCs react to a pathogen in the body |
First, T Cells identify the pathogen, and relay that information to B Cells that produce antigens that lock onto the pathogen. The Phagocytes then finish the job by eliminating the disease |
|
|
Antigens |
Produced by B Cells and they lock onto the pathogen and immobilize it. |
|
|
Antigens |
Produced by B Cells and they lock onto the pathogen and immobilize it. |
|
|
Antibodies |
Present if the disease has already been inside the body and makes the host immune to a particular disease |
|

|
|
Antibodies |
Present if the disease has already been inside the body and makes the host immune to a particular disease |
|
|
What do vaccines do? |
They inject a weakened or dead version of the disease into a body and provides it with the antibodies necessary to be immune to the disease |
