The Immune System

The Immune System

The  immune system is the system that protects the body from  biological germs and viruses.                                           

 In order for your immune system to function properly, it needs to sense a big selection of agents, known as white blood cells to  parasites and fight the different bacteria and viruses in our body.

 The Mucus Membranes

The Mucus Membranes are used to make the mucus in your nose. And the mucus that the mucus membranes make is used to protect your body from Viruses and microbes. How it 

Works are that when microbes or viruses entre from your nose, they get stuck in the mucus and the mucus in a short time hardens.

Tonsils

The Tonsils help the immune system by stopping germs to continue into the esophagus. Inside the Tonsils, there is a lot of white blood cells and antibodies to kill the germs.

Lymphatic Vessels

The Lymphatic Vessels are a really important part of the immune system. The Lymphatic Vessels bring lymph fluid who contains antibodies and white blood cells to the part of the body where they need them.

Lymph Nodes

 The lymph nodes are used to filter Harmful Bacteria and cancerous cells. And it helps your body with infections. Finally, it has a big role in cancer diagnosis and treatment.

Thymus 

The Thymus is used to make T cells. does T cells are used to produce white blood cells.

Skin

The Skin is used to stop bacteria and viruses and to stop infections from happening. And the skin has substances that are used to fight germs.

Spleen

The Spleen plays multiple roles in the human body. It acts as a germ filter for red blood cells. Our Platelets and White Blood Cells are stored in the Spleen. And the Spleen helps fight certain types of bacteria. 

Bone Marrow

The Bone Marrow is used to make red and white blood cells, platelets, and Lymphocytes.

In some species and humans there are two important subsystems which are the flowing;innate immune system and  adaptive immune system How the innate immune system works; this subsystem works and protects your body from viruses before it spreads and infects your body.

The immune system works with the circulatory system.

It works closely with this system to transport needs to the lymphatic system.

Analogy:

The immune system is like a security camera in a bank that catches a robber

. catches Viruses and germs

. catches robbers like the immune system catches diseases .

The Excretory System

Excretory System

Body System Function:

The Excretory System removes solid, liquid and, gaseous waste.

Body System (major) Organs: 

Kidneys:
The body has two shaped-like beans that filter blood from the urine.

Large Intestine:
It holds the material that can’t be digested. It absorbs the remaining water trapped in the food waste.The remaining part comes out of the body called feces.

Liver:
Located on top of the stomach, it makes a bile (a greenish-brown fluid),

stored in the gallbladder. The Bile breaks up fat molecules in the
small intestine which goes down to the large intestine.

Skin: It is the body's largest organ, this organ removes liquid.The top
layer of skin contains millions of sweat glands.These sweat glands release wastes in the form of sweat,

excess water, and urea (a protein). 

Interaction with Other Systems:

The excretory system has a close partnership with both circulatory
and endocrine systems.The blood circulates through the body
and passes through one of the two kidneys. Urea, uric acid, and water
and removed from the blood. Most of the water is put back in the system.

The excretory system also has a close connection with the digestive
system. It collects undigested solid.The excretory filters to compound from the
bloodstream then it collects from the urine. They control the amount of the body's
water. 

The excretory system has another connection with the respiratory
and urinary system. The lungs in the respiration removes waste products such
as carbon dioxide. 

The excretory system has a connection with the muscular and
nervous system. It has an interaction between our muscles and our nervous
system. Our endocrine works closely with our brains and our central
nervous system to control our creation of specific hormones and enzymes. 



Analogy

Analogy Explanation
The water filter system is a good analogy for the excretory system. It is a good example because both the systems jobs are to remove waste and purify.

Circulatory System

circulatory system!!!!!
credited by VSRao

Body System Function:

The Circulatory system is an organ system  that gives blood to circulate and transport nutrients, oxygen,
carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and
help in fighting diseases.

Body System Organs:

There are 3 main organs. The first one is the heart. The function of the heart is to pump blood around the
body via and giving supplying oxygen and nutrients to the tissues and removing carbon dioxide and
other wastes. The second one is the lungs main role in the circulatory system is to bring in air from your
surroundings and pass oxygen into the bloodstream. From there, it circulates to the rest of the body.
Arteries carry oxygen and rich blood from the heart through the body. Veins carry oxygen and poor
blood back to the heart.

Interaction with other Systems:

the circulatory system works closely with other systems in our bodies.
It supplies oxygen and nutrients to our bodies by working with the respiratory system.
At the same time, the circulatory system helps carry waste and carbon dioxide out of the body.
It also works with the digestive system to get nutrients distributed through your body.
While the digestive system collects and removes undigested solids, the excretory system filters compounds
from the bloodstream and collects them in urine.

Analogy Explanation:

The circulatory system is like a highway. The human body is the city.
The veins and arteries are the roads where things are transported.
The trucks are like blood being carried into and out of the city and cars are
like the oxygen and nutrients transported across the system.

The Skeletal System

  

The skeletal system works forms a strong structure for the body, gives the body its shape, protects the inside organs, and makes red blood cells.

The skeletal system is comprised of:

Bones: their purpose is to protect and support the function of other organs in the body. Bones store minerals and provide blood protection while producing red and white blood cells.

Cartilage: A connective tissue located throughout the body. Cartilage supports the structure of many body parts and functions like the bones, ribs, ears and nose.

Tendons: Provide the connection between muscle and bone. Tendons work with the muscles to allow movement, since they can withstand pressure and tension.

Ligaments: Connect bones to other bones. They provide stability to joints during rest and active movement.

Joints: Made up of bones, tendons and ligaments, they allow for a vast range of movement.

Pivot: Found at the top of the spine, it allows your head to move from side to side

Hinge: This type of joint can open and close like a door. The elbow is an example of a hinge joint.

Gliding joints:This type of joint has two bone plates that glide against one another. Gliding joints can be found in the ankles and wrists.

Ball-and-socket joints: Found in the shoulder and hips, this type of joint allows forward motion, backward motion and circular rotation.

The skeletal system does not work alone. It interacts with the muscular system. Muscles connect to the skeleton and contract and relax to move the skeleton. Ligaments and bones working together make the process of movement happen smoothly. The bones in the skeleton also work with the circulatory system. The marrow inside the bones produces the red and white blood cells that are needed to ward against disease and provide oxygen and remove waste from all the cells in the body.

Analogy

The Skeletal System is like the frame of a house because a house frame:

• provides a strong structure, 
• forms its shape, and 
• protects the insides of the house.

The bones are like the wooden beams because they provide the structure. The ligaments are like the nails that connect the beams to one another. Hinge joints are found in doors, while gliding joints are found in the sliding doors of a house.

Structure and Function

The main function of the spine is to provide support for the body and head, withstand impact and protect the spinal cord. The vertebrae are uniquely shaped to perform these functions.
1. It is made of hard compact bone tissue, which protects the spine. However, they needed to have a hole in the middle so that the spinal cord can pass through.
2. It is made of several smaller bones (vertebrae). This allows the spine to flex making it possible for us to bend over, while also providing some room to cushion the impact when we jump. If it was one long bony column, it would probably dig into our brain every time we played jump rope.
3. The different vertebrae  have unique shapes depending on where they are located, which allows different muscles and ligaments to be attached to them. This provides a way for each section (or vertebrae) to interact with the muscular system giving mechanical support so that we can remain upright.
