Fish
how do fish breath?
Through their gills
What is the only organ that they rely on to breath?
Their lungs
What is my heart structure?
3 chambers, 1 ventricle and 2 atriums
what do we rely on to breath
lungs
what is the cloaca used for?
It is used for both waste and reproductive
How many chambers do a fishes heart have?
Fish have two chambers. 1 ventricle 1 atrium
How many chambers does the heart have?
2 atrium and 1 ventricle
T or F - has a basic and short digestive system
True
What starts the digestive system
mouth by chewing up food
How many times does it take to make a complete cycle of oxygen?
2 inhales and 2 exhales making a total of 4 times to make complete cycle. 1 inhale 1 exhale 2 inhale 2 exhale
How do fish Oxygenate their blood?
Using small blood vessels within their gills to absorb the oxygen.
We have a muscle that pushes food to our stomach
An esophagus
What happens in the ventricle
blood collects and mixes with the rich oxygenated blood and poorly oxygenated blood.
what gas do we inhale and what gas do we exhale
we inhale oxygen and we exhale carbon dioxide
what are the ways I breath?
Using my lungs and 9 air sacs
T or F - fish digestion starts when they chew their food
FALSE
analogous or homologous - alligator legs to human arms
Homologous
What is the muscle that pushes food down to my stomach
my esophagus
What do the villi do in the small intestine
the absorb nutrients that then gets put into the blood system to be transported to the body for energy.
where do I hold my food before it gest digested
the Crop
When the blood is pumped through the heart is it oxygenated or poorly oxygenated?
The blood is poorly oxygenated when pumped through the heart.
Can we breathe through our skin underwater and why?
No, because we have thick scaly skin and we only have lungs to rely on.
I have these as a baby then I trade it off for an ability while also relying on another organ on land
Gills and trade gills for the ability to breathe through my skin under water while also using my lungs on land.
What is the heart structure and explain.
the heart structure is that there are 4 chambers 2 ventricles and 2 atriums that are separated by a wall. On one side is 1 atrium and 1 ventricle that holds poorly oxygenated blood. The other side has 1 atrium and 1 ventricle that holds rich oxygenated blood.
How do we use our stomach and what do we swallow to help break down our food? Where does our food go to for breakdown?
The stomach acts as a bridge between the crop and the gizzard. We swallow small stones that go to our gizzard to help break down our food.
