Segmented worms move by peristalsis. These are waves that flow through the body making the segmented worm turn and bend flexibly.
The circulatory system of a cow is similar to the one in other mammals. The main components are the heart, blood vessels and of course the blood among others.
The taxonomic grouping of arthropods is called a phylum. Among other traits, arthropods are characterized by joint appendages and segmented bodies covered by an exoskeleton made of chitin. They have an internal body cavity called a hemocoel and an open circulatory system.
The heart is the pump pushing the oxygenated blood through the body via the circulatory system and returns oxygen depleted blood to the lungs to be re-oxygenated. Simply put, the circulatory system provides the body and heart with, among other things, oxygen.
The general consensus among evolutionists is that fish evolved from segmented worms.
Respiration ! The process by which CO2 is exhaled from the lungs and is replaced by O2
Its main role is to transport oxygen and nourishing substances to the cells of the body, among other important tasks.
Ganymede is unique among solar system moons in that it possesses a significant magnetosphere. This is possibly due to convection within its liquid core.
Earth is the only planet known to have life on it.
Soya beans is the most unique among pulses because of the number of proteins that it contains.
The circulatory system transports food oxygen and waste from the rest.The digestive system breaks down food into nutrients and puts them in the blood. The lungs (respiratory system) take oxygen from the air and puts them in the blood, and takes carbon-dioxide from the blood and puts it in the air. The kidneys (excretory system) take the chemical waste out of the blood and excrete it as urine.So blood is the common factor here, and it is the veins, arteries, and the heart that circulates blood, nutrients ("food"), oxygen, and chemical waste throughout the body. The veins, arteries, and heart combined are the circulatory system.
Among other features, Arthropods have segmented bodies, an exoskeleton made from chitin, and joint appendages.
Nebraska's legislature is unique among all state legislatures in the nation because it has a single-house system. it is called unicameral.
