Nervous System
In the Gray Wolf Nervous System and in the Human Respiratory system, they both have a spinal cord, a brain, and a cerebellum. (All performing the same action to help control the activity of muscles and to handle reflexes and information of the brain. There are not any major differences between the nervous system of the Gray Wolf and the human.
Circulatory System
In both circulatory systems, there are blood vessels and arteries. The blood vessels in both organisms take blood to the heart while the arteries take blood away from the heart. There is also a heart that can circulate all the blood throughout the body. In both organisms, the heart has the job of pumping all the blood in the body to the places that it needs to go, whether the lungs to get oxygenated or to cells in the body to drop off the oxygen that they got from the lungs. There are not any major differences between the circulatory system of the wolf and the circulatory system of the human.
Respiratory System
In both respiratory systems, there is a set of lungs, a diaphragm, trachea, and a nose. All of these organs perform the same functions in both organisms. Both organisms get oxygen by breathing through the nose and then having the oxygen transferred by the trachea to the lungs. There are not any major differences between the respiratory system of the human and the respiratory system of the wolf.
Digestive System
In both digestive systems, an esophagus, liver, and stomach are present. All of the organs in both organisms perform the same functions. All the organs above help the organism digest the food that it takes in. However, in the human digestive system, the flat and semi-sharp teeth are adapted to the human's omnivorous diet while the wolf's digestive system involves sharp canine teeth that can cut through meat easier since it is a carnivore, not an omnivore like a human.
Excretory System
In both of the excretory systems, there is a set of kidneys, a bladder, a ureter, and a urethra. All of these organs provide the same functions in both systems. They help eliminate the waste that the cells in the body of each organism do not need and need to get rid of. There are not any major differences between the system between each organism.
Skeletal System
In both skeletal systems, a skull, femur, and a set of ribs is present. These bones have the job of protecting vital organs and providing shape to the body in both organisms. However, there is a clavicle in the human skeletal system while the Gray Wolf does no thane one. In the human, the clavicle has the job of letting the arm move away from the body.
Muscular System
In both muscular systems, there is a deltoid, latissimus dorsi, and a trapezius muscle present. These organs function the same and provide the same results in both organisms. However, in the human muscular system, the forelimbs can rotate due to its muscular set up while the wolf's forelimbs can't rotate due to the set up of its muscular system
