Cell Organization !

SCIENCE

Giulia Bennett #3 5-C

The cell is the basic unit of life. It has groups of cells. The groups are: cells> tissues> organs> organ system> organism.

This is when a group of cells get together and form a groups with a different name. They are a much bigger organization.

CELLS CELLS There are many types of cells. I going to mention 2 types of cells, plant cells and animal cells . All living organisms on earth are divided in pieces called cells. There are smaller pieces to cell that include proteins and organelles . There are also larger pieces called tissues and system . Cells are small compartment that hold all of the biological equipment necessary to keep an organism alive and successful on earth. A main purpose of a cell is to be organized.

Tissues

be grouped into 4 different types . The animals have 4 tissue ssue is a cell comprising the central nervous system.

Organ An Organ is a group of one or more kinds of tissues that work together to perform the same function. There are many organs in your body but I ‘m only going to talk about three. An organ I'm going to talk about is the lung. 1.Did you know oxygen is needed by the body's cells, is absorbed in the lungs. The second organ I'm going to talk about is the heart. 2.The muscular heart energy giving blood to all parts of the body. The last organ I'm going to talk about is small intestine. 3.In the small intestine most of the nutrients from food are absorbed in here.

Organ System

The Organ Systems are composed of two or more different organs that work together to provide a common function. There are ten major Organ Systems in the human body. They are: The Skeletal System, Muscular System, Circulatory System, Nervous System, Respiratory System, Digestive System, Excretory System, Endocrine System, Reproductive System (male, female)and Lymphatic / Immune System.

Organisms One celled organisms do all life processes with one cell. One of the jobs they always do is Store food .They always need to grow and reproduce. Another single cell organisms is a diatom. They are classified as proteins is great food for fish , wails, and other water animals. They are single celled organisms all around you! There are classified as helpful and harmful. Ex: helpful are the bacteria's that are used to make cheese and yogurt, harmful: strep throat – diseases. They break down the remains of dead plants and animals , and they return material from dead organisms to the environment. In conclusion these are one celled organisms.

The Human Body The Human Body Systems Systems

The digestivesystem is one of the human body systems . There are a lot more like: Skeletal system, the muscular system , the circulatory systems, nervous system, respiratory system, excretory system, endocrine system, reproductive system, and lymphatic /immune system. Those are the systems in the human body that help your body in many ways.

Circulatory System • The circulatory system moves blood all over your body. Your heart some time help your circulatory system.

By: Farid 5-c

Heart The heart has 4 valves. A valve is like a door. When 2 valves are open 2 are closed then 2 open and 2 close and so on. The heart has chambers , they are: the left atrium ,the right atrium, the left ventricle, and the right ventricle. The heart pumps blood to the body by squeezing itself. The heart’s job is to pump blood to all of the parts of the body. It beats more than 72 times per minute. It is the organ that never tires until you die. In all of your life it could beat more

Veins and Arteries

Veins : veins function is to return poorly oxygenated blood to the heart. The thick outer layer of the vein is made of collagen , and the interior has epithelial cells called intima. Most veins have flaps called venous valves that prevent blood from flowing back. The precise location of veins is much more variable from person to person than the arteries. Arteries : arteries are blood vessels that carry blood away from the heart and gives oxygen to other parts of the body. Arteries have three layers a muscular middle layer, a tissue outer layer, and an inner smooth layer. The muscular middle layer helps the heart to pump blood.

The Respiratory System

SEBASTIAN TORRES 5-C

The respiratory system brings oxygen to the blood, and removes carbon dioxide from it. They are the central organs. The air goes through tubes called bronchi. Then they come into smaller tubes called alveoli. Alveoli is surrounded by capillaries. Oxygen passes from alveoli into blood and carbon dioxide from blood to alveoli. Air moves well because of changing of the chest. When you inhale the diaphragm goes down and when you exhale the diaphragm goes up and relaxes.

Inhale and Exhale By: Giuliana Di Bono -When you breathe in, your diaphragm is relaxed. -When you inhale, your diaphragm is pulling downward and with combined contraction. -When you breathe in, air goes into your mouth or nose. -The lungs fill up with air and send out air. -You breath in and out by the nose or mouth. -the blood picks up fresh oxygen from air you need and drops of carbon dioxide. -You get rid of carbon dioxide by breathing out or you exhale.

Digestive System

out of your body . Digestion is mixing food wit

Digestion Process

By: Naomi Frey 5c

The digestive system changes food so the body can use it. The digestive process begins in the mouth then teeth bite and chew the food in to small pieces and saliva makes the food softer. After that, you swallow the food and it goes into the esophagus. Food moves through the esophagus and into the stomach, the food becomes a thick paste. The stomach moves the food into the small intestine. Food slowly moves through the small intestine. Enzymes helps break the food into tiny parts. The food becomes a liquid. The body absorbs the parts of the food it needs. The food parts go into the blood. Blood carries the food parts to all the body. The body does not use some parts of the food. This waste matter moves into the large intestine. It pushes the waste out of the body. Food is your fuel. Your body gets energy from your food. Vitamins, proteins, and fats also give you nourishment.

Nervous System

Definition:Nervous system is the part of brain that controls your senses your thoughts involuntary and Your nervous system controls your voluntary actions. physical and mental activites.It is divided in three parts .One of them controls your heartbeats and your breathing. It controls your involuntary body parts. You cannot control this part of the nervous system. The second part controls your voluntary actions. It controls your voluntary actions .It controls thoughts and organizes activity. The last part controls your senses of smell, sight, sound, taste and touch.

THE BRAIN -the

By Hector Lorenzo 5C

brain controls your body. -it is soft, wet and wrinkled -made up of 10 billion nerve cells and 50 billion other cells -it coordinates most voluntary movement it monitors and regulate body process. -a lot of parts of the brain do different things. -humans brains are more complex than animal brains -the parts of the brain are: cerebellum, cerebrum, brain stem, pituitary gland , and hypothalamus -The brain floats in liquid -The brain receives all the messages of your body -Without your brain you couldn't do anything. -Your brain helps you do everything -The largest part of your brain is the cerebrum -The second largest section is the cerebellum -The tiniest section is the brain stem

Musculatory S ystem The musculatory system is important because it allows the skeleton of the body to move. The muscles also play other important role. Such as giving form to the body, regulating the body's temperature and controlling the blood flow of the body. There are three types of muscle tissue : cardiac, smooth and skeletal. Cardiac muscle is a muscle tissue that is used in the heart. The cardiac muscle tissue is very strong ant it contracts automatically under the influence of the heart itself without the control of the brain. -Smooth Muscle can be found in the walls of the blood vessels digestive passageways such as the esophagus and the small and large intestines. It functions by providing a series of wavelike contractions known as peristalsis . Smooth muscle contractions are regulated by the autonomic part of the nervous system meaning that contractions cannot be controlled by conscious thought. -Skeletal Muscle is the type that makes up all of the muscles attached to the skeleton and allow its movement. Skeletal muscles all have a origin and a insertion. Without the musculatory system we couldn’t do anything.

The Skeletal System The skeletal system gives your body shape, it protects the parts that are inside your body, and it helps you move and stand. It is made of bones and the bones are very hard. The hollow spaces make your bones very light and the skull bones protect your eyes, brain and your ears. The rib bones are very flat and it protects your heart lungs, and the stomach. The other thing is that the spine is an arrow of small bones in the back and it protects the spinal cord. The hand has a lot of little bones.

Connective Tissues(Tendons and Ligaments)

Connective Tissue

Ligament knee

and tendon of a

•Tendon : Strong band of connective tissues, that puts a muscle together with a bone. •Ligament :A tough band of tissues connecting bones, or supporting an organ or joint in place. • •Wiggle your fingers. See something moving, those are your tendons. They join a muscle with a bone, that is why we have our fingers put together to our palm. If we didn’t have tendons we could not move well, because they connect muscles to bones. Valeria 5-c •

The Endocrine System

The rush of energy you feel when you are frightened or excited is produced by the endocrine system. The endocrine system consist of glands. A gland is an organ that send a chemicals messengers called hormones to other parts of the body. Hormones affect activity of cells far from where they are produced. They diffuse into the blood and are carried from where they are needed. The body produces many types of hormones. Each one acts on a specific type of cell. Endocrine glands are located through the body. The thyroid gland which is located in the neck region controls the body metabolism, or how cells provide energy. The adrenal glands, which are located above each kidney are involved in the body’s reaction to dangerous or frightening situations, and the pancreas which are in the abdomen maintain blood sugar level.

Excretory

System The excretory system is responsible for ridding the body’s waste. It also recall that undigested food it is removed from the large intestine. It is called the excretory system because it takes over for the digestive system and flushes the waste from the digestive track. The excretory system plays a very important roll. Without it wastes it would quickly poison the body.

Keeping Healthy

•Healthy is a way of life. It helps us prevent germs, allergies, and getting sick. Washing hands is the most important resource of healthy. You contain millions of germs on your hand; you eat, touch, play, write and other things with your hands. There are many ways to get healthy; your stomach need proteins every day. So people eat many important foods like vegetables and fruits.

Diet and Exercise Keeping Healthy

oods that have vitamins gives cells the nutrients they need. Exercise keeps muscle reath deeper and your body works efficiently. Also refusing to smoke or take drugs
