How does blood move in the circulatory system of a land amphibian?
Frogs have a heart and blood vessels like all other vertebrates. The heart pumps deoxygenated blood from the body to the lungs, and then pumps oxygenated blood from the lungs to the body. However, frogs only have a three chambered heart, which permits oxygen rich and oxygen poor blood to mix. This is less effecient than the four chambered hearts of mammals and birds.
What is the circulation of a bivalves?
Bivalves have an open circulatory system, where blood is pumped by a heart into a hemocoel, bathes the tissues, and then is filtered through the gills for oxygen exchange before returning to the heart. This system is less efficient than closed circulatory systems found in some other animals.
Compare grasshoppers circulatory to that of a crayfish circulatory?
This idiot is wrong. Maybe if you paid attention in Ms. Roberts class you would know that grasshoppers have a closed ciculatory system and crayfish have an open with very dark blackish blood. They do not have purple or green blood.
Do arthropods have a open circulatory system?
Yes, most arthropods have an open circulatory system, which means that their blood, called hemolymph, directly bathes their tissues. This system is less efficient at transporting oxygen compared to closed circulatory systems found in vertebrates.
How does the circulatory system use ATP?
The circulatory system uses ATP to power the contraction of the heart muscle for pumping blood throughout the body. ATP is required for the maintenance of the ion gradients necessary for muscle contraction and relaxation in the heart. Additionally, ATP is used for the active transport of ions across cell membranes to regulate blood pressure and flow.
What kind of exercise improves the cardiovascular and respiratory system?
When you exercise you are using muscles of the circulatory system and respitory system, and when you use muscles, they get stronger. When muscles of a body system are stronger, the system improves.
What is the disadvantage of a closed circulatory system?
Advantage of open circulatory system: * requires less engergy for distribution * it need less need of oxygen * blood pressure remain low Disadvantages for open circulatory system: * not very effective, because fluid is pumbed under low pressure, so it corculates more slowly than in closed circulatory system Advantage of closed circulatory system * Operates much higher blood pressure * blood pumped under high pressure so it reaches destination quickly * immune response are much Stronger, helping body fight infection Disadvantage: * stronger heart is required, more energy to maintain * is complex but more powerful
What is made from the alveoli from the circulatory system?
to be honest i don't know and i could care less :)
How do earthworms benefit from a closed circulatory system?
Earthworms have a closed circulatory system, meaning that they contain blood in different blood vessels; the Arteries which are a form of blood vessels that carry blood away from the heart, the veins which are blood vessels that carry blood toward the heart, and the capillaries which are tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body, a animal is classified as a closed circulatory because all of these vessels are pumped via its heart beats which is then pushed throughout its body by contractions callled 'Peristalsis'
Which two systems carry oxygen from outside of your body to the cells of your body?
i don't really know and i could honesty care less! and by the way i wont to rap u in bed
How does the circulatory system connect to the nervous system?
AnswerThe nervous system sends a signal to the heart to make it beat. I also helps control not just the beat, but also the blood pressure as well. The part of the brain that controls the heart beat is the medulla oblongatta in the brain stem.
Mollusks like clams and snails have a simple heart that pumps through open-ended vessels?
Mollusks, a member of the crustacean family, have an open circulatory system meaning blood flows freely within their body cavity. However they still have a three chambered heart. The heart pumps blood through open-ended vessels and the blood simply flows back into the heart on it's own or through incidental muscular contractions of the mollusks body during feeding or moving.
