the lymphatic system

the lymphatic system has many jobs. first it serves as a defense mechanisms because it filters out organisms that cause disease. It also produces certain white blood cells and generates antibodies. the lymphatic system distributs fluids and nutrients in the body. it also drains excess fluids and protein so that tissues do not swell up. here is a picture of the lymphatic system

Skeletal System (by Michael Collins)

There are 27 bones in each hand, with 8 in the wrist, 5 in the palm, and 14 in the fingers and the thumb. There are three bones in each finger, and 2 in the thumb. The distal phalanx, middle and the proximal phalanx are the bones that make up the fingers, although the thumb does not have a middle phalanx. While typing this, I believe I used all my finger-bones, although I might not have used my metacarpals, which are the bones that connect your fingers to your wrist.

Urinary System

      Your body makes chemical waste items that it can not use.  Then it goes to the bloodstream to then go to the kidneys. Then the kidneys sepraet the waste from the stuff your body needs. when your bladder becames too full sends a message to your brain. you feel the need to pee and start looking for a place to pee.

the SPLEEN

one of the most made fun of body parts in a human body, but it is the biggest of the lymphoid tissues is the spleen. It is just about the size of the heart and can hold up to .3 gallons of blood. The spleen is located on the left side of your body right behind the stomach. This organ has an important job to the digestive system . it produced white blood cells, filters blood and destroyed old red blood cells. here is a picture of the whole digestive tract and the spleen. the spleen is made out of a spongy material and it is hard to repair.
here is a picture of the spleen and its sections

The Lymphatic system is mostly used for filtering out bacterias and diseases. It also produces kinds of white blood cells. One of its other uses is to distribute fluids and nutrients through the body. It and the cardiovascular system are closly realated.

digestive system

the digestive system starts at your esophagus goes down to your stomach were the acids in you body brake down the food into smaler peices. Then enters your small intestine then the large intestine. After it goes through the stomach and the intestins it will go to your ascending colon wich goes to the descending colon were it is turned into poo. From there it goes to your rectum but not out then to the anal canal and then out the BUTT!!!. Were it is flushed down the toilet. There is a picture of the digestive system above.

Skeletal System

All joints represent some type of mechanical movement such as an elbow joint is like a door hinge. Some of the other joints are hand joints, hip joints, and spine joints. I think that 

the joints are not that simple but that is a good way of representing them.

The upper part of the skull is made up of eleven parts. They are the Anterior Fontanelle, the Bregma, the Sagital Structure, the Coronal Structure, the Frontal Bone, the Lambda, the Lambdoid Structure, the Occipital Bone, Parietal Bone, the Parietal Foramen, and the Posterior Fontanelle. I am surprised there are so many parts of the upper skull.

The three bones that make up the Knee are the Femur, the Fibia, the Patella (or Kneecap). I thought there was more bones than that in a Knee.
