Hello, today we are going to be presenting our living organisms. Our names are-Ethan W, Jese L, Mateo G, and Matteo B.

They don't have a skeletal system but they have a hydrostatic skeleton that is divided into segments which is a flexible skeleton filled with fluid. Each segment of the worm’s body contains muscles that work independently of every other segment

*The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm.

The first nonspecific barrier of earthworms is the skin covering their entire body. The skin consists of the epidermis and a thin cuticle, which contains mucopolysaccharides acting as an antimicrobial barrier.

longitudinal muscles that run the length of the body and circular muscles that form circular bands around the body. Worms also have something called a hydrostatic skeleton. A hydrostatic skeleton or hydroskeleton is a type of skeleton supported by hydrostatic fluid pressure,

The earthworms each have two male openings and two sperm receptacles, which take in the sperm from another mate. The earthworms have a pair of ovaries that produce eggs. Earthworms are hermaphrodites where each earthworm contains both male and female sex organs.

The earthworms skin serves as its respiratory organ, which is what explains their wet skin.

*Earthworms have a complex digestive system consisting of the mouth, pharynx, esophagus, crop, gizzard, and intestine. These organs work together to pass soil that the worm ingests through its body.

*worm produce sexually by mating with other worms

*they go through mitosis

*came from Asia and Europe

*One group, the Cycloneuralia, remained limbless: they gave rise to some modern worms like nematodes. The other, the Lobopodians, evolved legs.

They have a nervous system running along their body.The central nerve cords are connected to other nerves like the rungs of a ladder throughout the body. Two ganglial nervous tissues at the head function similar to a simple brain. The nervous system of an earthworm comprises of a ventral nerve cord and peripheral nerves

One major difference is that worms use their skin to breathe, humans use their lungs.

Worms breathe air in and carbon dioxide out, like us, but they don't have lungs.
