The Difference Between Great White Shark and The Human Body

Respiratory system

The Great White Shark


Sharks can respire by pumping water over their gills by opening and closing their mouths. From the mouth, water enters the gill chambers and exits through the gill slits. Blood in the gill filaments absorbs oxygen from the incoming water.

In a seperate chamber beneath the gills, the heart pumps oxygen-depleted blood to capillary beds in the arches. Water is pumped into the mouth and out across the gills counter to the direction of blood flow. This exchange system greatly enhances the rate and efficiency of oxygen diffusion into the blood.

The Human Body

Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity.

The heart is a muscular organ that pumps blood throughout your blood vessels. it has

How Is It Similar:

They have a nose and a mouth


How Is It Different

sharks do not have a trachea, lungs, and a diaphragm for gas exchange. Instead of alveoli, the oxygen is absorbed by gills. Sharks also absorb oxygen from water rather than the air like humans do.

Digestive system

The Great White Shark

Sharks have U-shaped stomachs that use very strong acids and enzymes to dissolve most of what is eaten. The stomach produces an easily absorbed, soupy mush. Only this liquid mush enters the intestines because the pyloric valve (the valve between the stomach and the intestines) is small. Indigestible things, (like very large bones and non-nutritive items) are vomited.

The Human Body

The human body needs fuel to live. We eat food for fuel. But just getting the food into the body is only a small part of the process. The food must be broken down into chemicals that the body can use. This whole process is called digestion. Some of the organs involved in digestion are the mouth,esophagus, stomach, small and large intestines, gallbladder, Pancreas and liver. Follow the lizards to find out how the body uses the food we eat.

Has a Stomach same like humans.


How Is It Different

humans have an anus instead of a cloaca. Great white sharks have a u shaped


The Skeletal System

The Great White Shark

A sharks skeleton differs from that of other fish because it is composed entirely of cartilage. Cartilage is a strong and durable material but also light weight and flexible. the general movements of the shark in a variety of ways. For example, cartilage is lighter than bone and helps keep the shark from sinking (since a shark has no swim bladder for buoyancy like other fish) and allows the shark to turn in a tighter radius than other fish. Cartilage found in the jaws and backbones of sharks require more strength then the cartilage found in the fins.

The Human Body

Without your skeleton your body would collapse into a heap. Your skeleton is strong but light. Without bones you'd be just a puddle of skin and guts on the floor. Bones provide the structure for muscles to attach so that our bodies are able to move. Tendons are tough inelastic bands that hold attach muscle to bone.

How Is It Similar:

We both human and sharks have some sort of Skeleton to keep our body structure and not collapse.


How Is It Different

Great white sharks have a cartilage and human don't


The Waste System

The Great White Shark

Sharks get rid of body waste in two ways. Some waste products, such as carbon dioxide, are expelled through the gills. Other body waste is excreted through the digestive tract.

The Human Body

The waste removal system, or excretory system, is actually shared by several body systems. The main contributor to excretion is the gastrointestinal tract, GI tract. It is made mainly of epithelial tissue with a mucosal lining and it is in the shape of a tube. The last part of the tube is known as the colon, rectum, anal canal, and anus.

How Is It Similar:

Sharks and Human has the same common thing, the watse goes throught a tube and it comes out.


How Is It Different

The waste goes through diffrent stages between human and Great white sharks. The Great white sharks has another way of getting rid of body waste its from the gills.


The Reproductive System

The Great White Shark

Male: Claspers are rolls of cartilage that become stiffened with calcium in the adult. The presence or absence of these claspers make it very easy to differentiate males from females. Males also have paired testes, however the right one is always more developed than the left, which may be smaller or absent altogether.

Sharks are sexually dimorphic. That is, there are visual differences between males and females. Males, like the one seen in this picture, have pelvic claspers which are modified pelvic fins used for sperm delivery.

The testes are internal and are located in the anterior end of the body cavity within the epigonal organ. The urinary and reproductive tracts join together to form the urogenital sinus. From there the sperm is eventually released into the groove of the claspers and is then delivered to the female during copulation.



Female: Females do not have claspers. Instead they have a cloacal opening (as do the males) between the pelvic fins. The internal ovaries are found anteriorly in the body cavity and are paired, but as was the case with the male testes the left side is often reduced. Indeed, the left ovary often releases very few or no eggs.

The Human Body

Male: The main reproductive organs of the male body are the testes, which produce sperm and also male hormones, in the form of testosterone. The male reproductive system also includes the external genitals — the penis and the scrotum — and the internal structures, including the prostate gland, the vas deferentia (plural for the 2 vas deferens), the urethra, and the seminal vesicles.


Female: The ovaries are the main reproductive organs of a woman. The two ovaries, which are about the size and shape of almonds, produce female hormones (oestrogens and progesterone) and eggs (ova). All the other female reproductive organs are there to transport, nurture and otherwise meet the needs of the egg or developing fetus.
