Which joint did you choose as our most important joint?

 Why did you choose that joint?

What things would be difficult to do without that joint?

What movement can be done without the use of joints? (Example: blinking your eyes) 

 

The joint that I thought was most important was the jaw joint.  It is known as the temporomandibular joint.  I chose this joint because it allows movement of the mouth.  The bones that make up this joint also hold the teeth.  The teeth let us chew up the food that will give our body energy.  This joint also controls the opening and closing of our mouth to allow us to swallow liquids.  If we were not able to close our mouth the water would drain out and our bodies would become dehydrated.  Eventually without being able to eat and drink we would dehydrate and die.

The movement of the tongue is not controlled by a joint.  It is a voluntary muscle that is controlled by wanting it to.  It serves a purpose with swallowing to push the food towards the back of our throat to go down into the digestive system. 

• What three basic things do our bodies need in order survive? food, water, sleep, and energy.                     

     The three basic thing our body needs to survive are water to stay hydrated , food so that the body would not starve , energy to be active and helps the body work.

• If we exert ourselves, what are three (or more) signs that our bodies are in distress?

     When I exert myself I notice that I am huffing and puffing because I need more air to fill my lungs from the energy being used. I, also noticed that my body got hot and I started to sweat.  This is because my body is letting out water and helping me to cool down.  My heart rate increased when I exerted myself.  This was to be sure that there was enough blood to my arms and legs for the exercise that I was doing.  I noticed that I got thirsty because I was sweating and needed to put the water back in my body. 

• What can we do to make these signs go away ?
  

      To make the signs go away it is a good idea to take breaks during the activity and drink plenty of water.  Taking breaks will give me time to catch my breath and cool down.  I noticed this when I was doing  jumping jacks and stopped to sit for a minute to take a drink of water.  When I started back at jumping jacks I felt better.  
  

   1. What was the hardest part of this activity?  Doing the video because we were messing it up a lot and we did it 1 times before getting it right. But when we did it the second time it was way better and we felt a little better.
   
   2. Which organs do you think you put in the right places?

• Brain
• Eyes
  
• Heart
• Lungs
  
• Esophagus
• Gallbladder 
  
• Bladder
• Skin
• Large intestine
• Small intestine
• Kidneys
  
• Liver
• Stomach  because I learned about it in 3 grade for a mouth.
  

      
   Which organs do you think are probably in the wrong place?

• Trachea
• Pharynx
• Larynx
• Diaphragm
•  Pancreas
  
• Spleen\ \   because they do not make a lot of scene in though spots.
  

 Do we have cells similar to the aliens you created?  How or why not?

 

I believe that aliens and humans may have similar cells.  This is because it takes cells to make organs and the aliens have eyes, ears, and a mouth just like I do. They would need cells to make this possible.

 Humans (and probably aliens) have cells that have special functions.  What are some of these cells and what organs and systems are they a part of?  Give at least three examples and be specific.  (Example: Osteoclasts are cells that make up spongy bone inside of many of our bones.  This is part of the skeletal system.)

An example of a cell in humans and probably aliens is the immune cell.  These cells have special functions and are part of the immune system.  These cells are stored in the thymus, spleen, and bone marrow.  These are called the lymphoid organs.  Lymph nodes may store leukocytes as these are clumps of lymphoid tissue.  An example is white blood cells or leukocytes.  These cells work to fight infection and get rid of diseases. 

Another type of cell in humans and probably aliens is red blood cells. These cells also have special functions and are part of the cardiovascular system.  These cells are produced in the marrow of the bones and gather oxygen from our lungs to give to the rest of the body.  While they are supplying oxygen to our body they pick up waste to bring back for us to get rid of.  Red blood cells are pumped from the heart through our vessels to all parts of the body. 

The last example of cells in humans and probably in aliens are the muscle cell.  These cells make up the muscular system.  They are in all types of muscles from smooth, to cardiac, and skeletal.  The muscle cells are divided by which type of muscle they make up to determine what they do.  Skeletal muscle cells make up the skeletal muscles which help the body to carry out voluntary movements.  This would allow the alien and me to move and swim.  The cardiac muscle cells make up the heart which pumps the blood to the body so that we can have the oxygen or other nutrients to survive. While I am not sure if my alien has blood he would need nutrients to survive and some sort of carrier for oxygen to survive on earth.  Lastly are the smooth muscle cells which make up the tissues of the digestive system to allow our body to absorb and process food and eliminate waste.
