The anatomy of a dog

Today I am going to draw the anatomy of a dog and learn about what each part of its body does.

Here is my image:


Larynx

A dogs Larynx is its voice box which allows it to speak. When a dog becomes quite old there is a chance it mite get Laryngeal Paralysis a disease that some older dogs get when their larynx does not open and close when the dog breathes like it should normally do this makes the dog stressed when its hot because it breaths more rapidly but it can't.

Esophagus

The esophagus is a tube that connects the stomach to the mouth. The esophagus is located right in the chest and throat. The walls of the esophagus are made of muscles that move in wave like movements to push food into the stomach. When the dog has finished eating and there is no food in the esophagus the walls of the esophagus will collapse on each other to close it.

Stomach

The stomach is basically a little sack inside the dog that gets passed food by the esophagus. Inside the dogs stomach is many folds these folds are called gastric folds. The gastric folds help the stomach grind and digest food. once the food is eaten most of it leaves within 12 hours.

Small intestine

The small intestine is a tube like tunnel that connects the stomach to the large intestine. Despite its name the small intestine is actually bigger than than the large intestine. The small intestine is about two and a half times the size of your dog, For example if you have a dog that is about 24 centimetres its small intestine will be about 60 cm.

Large intestine

The large intestine basically just connects the small intestine to the anus. In a 40 pound dog the large intestine would be about 15 cm long. even though the large intestine is smaller than the small intestine it is actually thicker in diameter.

Trachea

The trachea (windpipe) is a big hollow tube that helps to let the air flow to and from the lungs. The trachea is located in the throat it joins the lungs and larynx together.


Kidney

The kidneys in a dog do exactly the same work as a humans kidneys by filtering the blood and collecting the body waste which will then be passed down to the bladder which when full will send note to the brain telling the dog that it needs a wee.

Spleen

The spleen helps by fighting of infections and removing aged and non working red blood cells from circulation.

Rectum

The rectum is a place to store the feces (poo) before it leaves the body.

Liver

The liver is an important organ for your dog it helps with digestion and blood clotting, it also removes toxins from the system.

Lungs

when a dog breathes in its lungs will collect all the air but will only breath out the part it doesn't need. The part the dog doesn't need is called carbon dioxide, the dog will breathe out the carbon dioxide and keep the part it needs, oxygen.

Heart

The heart has to sides one that collects blood from circulation and pumps it to the lungs while the other side does the opposite by collecting blood from the lungs and pumping it around the dogs body.

Spinal column

A dog's spinal column is their backbone. A dog's spinal column is a large group of bones that protects the spinal cord which houses all of the important nerves in a dogs back.
