Different chemicals, or reagents, cause different things to happen to the heart. Voluntary muscles, which are those over which the frog has control, occur in pairs of flexors and extensors.
One end was attached to a Z pin, which was attached to the very end where the apex is because that is Just tissue. The electrodes were rearranged to once again represent lead l, and thread was tied around the narrow groove of the heart between the atria and ventricles.
The contents of the common bile duct flow into the small intestine, where most of the digestion and absorption of food into the bloodstream takes place. Connected to each kidney is a ureter, a tube through which urine passes into the urinary bladder, a sac that stores urine until it passes out of the body through the cloaca.
The ovaries produce eggs, or female sex cells, which move through oviducts into the uteri, then through the cloaca outside the body. Veins from different parts of the body enter the right and left atria.
Conduct the frog dissection in the lab. Student sketches of the frog are sometimes unrepresentative of what they observed and of poor quality.
It was removed in a rectangular shape, going across the abdomen and up the sides and then across the neck. If you know which of your students are skilled in using PowerPoint, place one in each group. It also caused the P waves to become very difficult to see, if they were even present at all.
Next, stimulus was applied to create the illusion of a heart blockage. From the esophagus, swallowed food moves into the stomach and then into the small intestine. Then, the set up was changed to represent lead II, which only changed the location of the positive pin to the left thigh instead of shoulder.
Then the muscle was removed in the same fashion, and the heart was visible.
Ensure that each group can obtain a digital camera.

The testes produce sperm, or male sex cells, which move through sperm ducts, tubes that carry sperm into the cloaca, from which the sperm move outside the body.Lab Report Review (Frog Lab) Bioengineering -- Systems Physiology I Lab Report Comments Lab II: Frog Heart Experiment BIOEN Spring Rob MacLeod, Brian Birchler, Cris Lapierre.

Keep in mind that 6 students have already been assessed using this rubric. Changing it will affect their evaluations. Obtain a preserved frog, rinse the frog in the sink, and place it in a dissecting tray. 2. Label the following dissecting terms on the diagram below: (2 Points) dorsal surface ventral surface anterior end.
