Write the following:
Ascaris- Intestinal worm of pigs, horses, and humans, can be so numerous they can block the host’s intestine, female can produce 200,000 eggs per day
Hookworms
- mouth have cutting plates that clamp onto the intestinal wall of the host, feed on the blood of the host, may cause anemia in adults and slowed mental and physical development in children, enter the host through the bottom of the feet, 400 million people affected worldwide
Trichinella
-
live embedded in the host’s intestines, travel through the bloodstream to the muscles and form cysts, people get infected usually when they eat undercooked pork
Pinworms- most common roundworms, do not cause serious disease, live in the lower intestine, female lay eggs around the anus, eggs are picked up by the person’s hand and spread to whatever they touch
Filarial worms- live in the lymphatic system, causes fluid to accumulate in the limbs such as elephantiasis

#5. There bodies are flat so it puts them in direct contact with their environment, cells exchange gases through diffusion
#6. They have a gastrovascular cavity, Food enters the opening is digested and waste is eliminated through the same opening

Write the following:
A human is the primary host.
In the human’s intestines, proglottids
break off and are eliminated with the feces.
Eggs remain alive in the soil or grass for several months.
Grass is eaten by a cow, Eggs develop into larvae and go to cow’s bloodstream.
The larvae burrow into the cow’s muscles and form cysts.
We eat the undercooked beef and the cycle continues.

Adult flukes have both sexes. Eggs are fertilized by males in the primary host.
Fertilized eggs are excreted in feces or urine.
Fertilized eggs that land in fresh water develop into ciliated larvae that can swim.
The larvae enter a particular species of snail, where they reproduce asexually.
The young flukes leave the snail, climb up blades of grass and form cysts.
A grazing animal eats the grass and the cycle begins again.
