Risks. 1  Stroke. Both ET and EPT increase the risk of stroke. That risk goes away, however, soon after you stop taking hormones. 2  Blood clots. Risk increases if you take hormones by mouth. The risk may be lower if you use a transdermal estrogen, such as a patch, gel, or spray. 3  Uterine cancer.
A earthworm does not have a skeleton. It has bristles on each segment called setae that help the earthworm move. Earthworms have no limbs. The earthworm has two sets of muscles; one that makes it long and thin and one that makes it fat.t eats dirt, digesting the plant and animal matter in the dirt and then eliminates the rest. It has an esophagus for the food to go down, a crop to store the food in, a gizzard that grinds the food down, intestines for the food to pass through and take out nutrients and an anus for the food to come out.
Objectives: Describe the appearance of various organs found in the earthworm. Name the organs that make up various systems of the earthworm. Materials: Safety goggles, dissecting pins, gloves, forceps, lab apron, scissors, paper towel, scalpel, water, dissecting probe, preserved earthworm, hand lens, dissection tray.xcretory functions are carried on by nephridia, which are found in pairs in each body segment. They appear as tiny white fibers on the dorsal body wall. The earthworm has no gills or lungs. Gases are exchanged between the circulatory system and the environment through the moist skin.
