The purpose of this assignment is to dissect the anatomy of a frog. This deepens our understanding of the different parts of a frog working to keep it alive, using it as a comparison to our own anatomy.

Tympanum

The tympanum is the external ear drum on the side of a frogs head. The tympanum is responsible for a frog's sense of hearing.

Gullet

The gullet is where a frog's swallowed food enters. This is the entrance to a frogs digestive system.

Glottis

The glottis is the entrance to a frog's respiratory system, where air empties into the lungs. The glottis is aso where the vocal chords are located, used by the frog to croak.

Eustachian tube

The Eustachian tube is a tube that connects the eardrum to the inside of the jaw. The Eustachian tube is used to balance pressure in the inner ear, while the frog is submerged.

Frog Jumping vs human Jumping

When a human jumps, they jump perpendicular to the ground. This is because the force the legs exert is directly perpendicular to the ground, causing the human to move in the same direction. In contrast, the frog jumps at an angle, as it's legs propel at an angle to the ground.

Heart Chambers

The chambers are sectioned off areas located in the heart, working in tandem to pump blood in and out of the body. A frogs heart has three chambers: two atriums and one ventricle.

Bilateral Symmetry

Bilateral Symmetry is the symmetry across a singular line, where one side of the line is a reflection of the other side.

Lungs

The lungs are the main component of the repiratory system, responsible for extractign oxygen from air. A frog's lungs are noticeably underdeveloped compared to a humans, as they can also breathe through their skin.

Cloaca

The cloaca is the opening at the end of a frog. The cloaca is used to expel feces, urine and eggs.

External Reproduction

External Reproduction is the process of developing offspring outside of the animal. External Reproduction is done by frogs in the form of eggs, where the embryo is developed inside the egg.

Sexual Dimorphism

Sexual dimorphism are distinct differences between the two sexes of the same species, which are not directly involved in sexual reproduction. In frogs, both the male and female differ on their forelimbs, where males have nuptial pads.

Digestive System

The Digestive System is the system responsible for breaking down and extracting nutrients from food consumed. In a frog, the digestive system is consisted of the mouth, pharynx, esophagus, stomach, small intestine, large intestine and cloaca.

Circulatory System

The Circulatory System is responsible for circulating blood across the entire body, which delivers oxygen and other nutrients to places that need it. In a frog, the circulatory system is consisted of the heart and blood vessels (veins, arteries and capillaries).

Respiratory System

The Respiratory System is the system responsible for taking air in, and extracting oxygen from it, while expelling. any other waste products in the air. In a frog, the respiratory system is consisted of the mouth (including the surface), lungs and skin.

Excretory system

The Excretory System is the system responsible for getting waste out of the body. In a frog, the excretory system consists of the kidneys, ureters, bladder and cloaca.

Skeletal System

The skeletal system is the system responsible for maintaining the structure of the body. In a frog, the skeletal system are all the bones in it (important ones include the skull and spinal cord).

Nervous System

The Nervous system is the system responsible for sending signals and information to tell the body what to do, done via electrical pulses. The nervous system consists of the brain, spinal cord and other nerves around the body.

Muscular System

The muscular system is the system responsible for movement of the body and it's joints. In a frog, the muscular consists of muscles, tendons and ligaments.

Reproductive System

The reproductive system is the system responsible for the sexual reproduction in organisms. In a frog, the reproductive system consists of testes, vasa efferentia, urinogenital ducts and the cloaca in males, and a pair of ovaries and oviducts in females.
