Circulatory System of Northern Leopard Frog
Image of how circulation works in the Northern Leopard Frog
Heart: The Northern Leopard Frog has a three chamber heart with two atria and a single ventricle
- The veins in the frog give deoxygenated blood to the atrium from a variety of organs in the frogs body
- The left atrium in the frog receives oxygenated blood from the frogs lungs and skin
- The both left and right atrium drain into the single ventricle
- Very little mixing between the deoxygenated blood and oxygenated blood occurs because the ventricle is divided into narrow chambers that reduce the mixing of the two bloods
- Oxygenated blood is brought to the head/brain from the left atrium the arteries in the head/brain are called the carotid arteries
- Deoxygenated blood from the right atrium is brought to the pulmocutaneous arteries (skin and lungs where they can obtain fresh oxygen)
- The only blood that has been mixed goes to the aortic arches, but this blood has enough oxygen to be used by the rest of the body
- Unlike other animals the Northern Leopard Frog get's its blood under full pressure
