10/31 Interdependence of Organisms-2

Image
Summary : I learned about symbiosis.  It is when organisms interact.  There are three kinds of symbiosis; parasitism, commensalism, and mutualism. Backward-Looking : I didn't know much about the topic before we started. All I knew was that symbiosis was when organisms interact. I didn't know that there are three kinds of symbiosis, parasitism, commensalism, and mutualism.  Parasitism-one organism benefits and one organism is harmed(Example- a dog with fleas). Commensalism- when one organism benefits and the other organism doesn't care(Example- a bird living in a tree). Mutualism- when both organisms benefit(Example-boxer crab and anemones). Inward-Looking : I liked the work this week.  I liked the virtual rainforest scavenger hunt because it was nice to see the different animals.  I enjoyed the symbiosis foldable as well.  It was nice to see how symbiosis applies to students.Parasitism- Two students working on a project, one does all the work and both get the same gr

I learned so much!!!

Nervous System

Wikipedia Function: The nervous system's main function is controlling everything you do, whether voluntary or involuntary. Organs: Brain- The brain is the control center for your entire body. It controls things such as memory, planning, and other voluntary actions. It can also control things like your heart rate and digestion. Spinal Cord- The spinal cord carries signals and information from the brain to other parts of your body. Nerves-Nerves allow signal and information to travel from the brain to the spinal cord and all around the body. Interactions: The nervous system is like the circulatory system, they both interact with every other system. Some can be quite obvious like the muscular system. When you want to move your brain transmits signals to create movement. The nervous system is also in charge of involuntary actions like your heart beating, the breaking down of food and more. The digestive system works with your nervous system when the food is broken down

Urinary System

Function: The function of the urinary system is to filter out urine or soluble waste from the body. Organs: Kidneys- The kidneys remove liquid waste, urine, from the bloodstream and keep a sturdy level of salts in the blood. Ureters- The ureters are thin tubes in which carry urine from the kidneys to the bladder. Bladder- The bladder stores urine until emptied through the urethra. Urethra- Urine passes through this tube to leave the body. Interactions: The urinary system works closely with the circulatory system. Blood that travels through your bloodstream goes to the kidneys which are a part of the urinary system. Uric acid and urea are taken from the blood to be emptied out. As well as that, the urinary system has a connection with the endocrine system. The endocrine system has control over the urinary system. The endocrine system can control things such as how much you urinate depending on how much water in circulating through your body and monitors fluids. The urinar

Skeletal System

skeletalsystem.organsofthebody.com Function: The Skeletal System allows your body to move, provides structure, produces blood in the bone marrow, and protects your organs. We need the skeletal system to hold up our bodies our else we would be piles of muscles and organs. Organs and Functions: Bones: make up your body and protect you vital organs. Joints-You have three types of joints      Hinge joint- This joint is formed at the ankle, knee, and elbow allowing the bones to extend and   flex.      Ball and Socket joint- This joint can be found in the hip and allows movement and rotation in more than one direction.      Pivot: allows the head to move side to side, in other words pivot.      Gliding Joints: allows bones to glide up, down, side, side, and diagonally. Cartilage: connective tissue found in the larynx. Tendons: attach muscles to bones. Ligaments: connect to bones to two pieces of cartilage together. Interactions With Other Systems: The skeletal syste

Muscular System

Haiku Deck Function: The function of the muscular system is to allow your body to move through your bones. Organs: Skeletal- This is voluntary and works in pairs As well as that, it is attached to your bones. Voluntary means you decide whether it moves or not. Cardiac- This is involuntary and found in the heart. Involuntary means it naturally occurs. Smooth- This is involuntary and found in the stomach, veins, small and large intestines, esophagus, and bladder. As said earlier involuntary means it happens without you having to tell it to. Interactions:  The muscular system interacts with the nervous system. This is because most of the time you move because you are in control. In other words, your brain, part of the nervous system can control muscle movement. There are some movements you cannot control, involuntary movements, such as the beating of your heart. Also, smooth muscles that aid the digestion process. The smooth muscles can be found in the circulatory system, t

Digestive System

Image: Wikimedia Commons Function: The digestive system breaks the food you eat into nutrients and compounds. This is then absorbed into the bloodstream. Unwanted materials, waste, continue out of your body through the anus. Organs: Mouth-It is where digestion begins. When you start chewing your food it mixes with saliva and starts the process of breaking down food. Esophagus-It transports food from the mouth to the stomach. Stomach-It holds the food and continues the process of breaking down food. The food that is now a form of liquid or paste goes to the small intestine. Small Intestine-It continues to break down the food. After absorbing all the nutrients the rest (waste) moves to the large intestine. Large Intestine- The waste goes through the large intestine in liquid form which then changes into a solid. The solid waste is stored there until it gets passed on to the rectum. Rectum- It receives solid waste and holds it. It's main job is to inform the person&#

Respiratory System

philschatz.com Function: The respiratory system provides oxygen and gets rid of carbon dioxide. The main function is to trade gasses with the environment, such as releasing carbon dioxide for oxygen. The true purpose is to receive oxygen for the body. Organs: Nose- The nose is the main gateway into the respiratory tract from the outer surface. This is the very first section of the system in which air passes through. Mouth-The mouth is another, but not as commonly used entrance into the respiratory tract. Most breathing takes place through the nose, but the mouth can replace its function if necessary. Pharynx- The pharynx is a tube located behind the esophagus and larynx. Air inhaled travels down the beginning of the tube. The air continues to go downward and it finally enters the larynx through the epiglottis. Larynx- The larynx is connected to the trachea leading the air closer to the lungs. It is also known as the voice box because it has another function: vocalization.
