What are the substances carried by blood and their functions?
Blood carries oxygen through out your body. Your lungs inhale oxygen and the blood cells carry the oxygen to your heart. Then the heart makes more blood cells to carry more oxygen to pump more blood.
How the respiratory system is link to the circulatory system?
the circulatory and respiratory system are linked because when the heart gets oxegyn from the lungs, the arteries in the left of right atrium of the heart take that blood and give it to all the other cells in your body, pick up carbon dioxide as they go along, and that what you breathe out, then when you breathe in, the same cycle repeats over again
How does your circulatory system fight diseases?
it depends if your body is strong or healthy it does but does not kill the diseases
Why do the blood in the arteries flow in the one direction?
Understand that your circularory system is like a highway that moves in circles and the blood has to flow in those "circles" to deliver it's cargo. Otherwise, things would be dropped off to the wrong customer.
How does an open system contrast with a closed system?
An open system allows for the exchange of matter and energy between the system and outside of the system. A closed system only allows the exchange of energy; not matter.
What type of bleeding is easiest to control?
Venous blood flow is easiest to control. Arterial blood flow is hardest to control because it is under pressure from the heart.
Does a snake have an open circulatory system?
no they dont. They have a closed circulatory system because they are so long.
What three things does the circulatory system deliver to body cells?
The circulatory system transport oxygen and respiratory material (food) to the billions of our body cells.
Hemorrhage: Bleeding or the abnormal flow of blood. The patient may have an internal hemorrhage that is invisible or an external hemorrhage that is visible on the outside of the body. Bleeding into the spleen or liver is internal hemorrhage. Bleeding from a cut on the face is an external hemorrhage. The term "hemorrhagic" comes from the Greek "haima," blood + rhegnumai," to break forth = a free and forceful escape of blood.
What is the site where oxygen enters the pulmonary blood?
Oxygen enters the blood in the alveoli of the lungs
What structures of the heart make it powerful pumping organ?
The whole heart is made of muscle to do the pumping
What do the main parts of the circulatory system do?
The main parts of the circulatory system are the heart, arteries and veins. Together, they work together to pump blood throughout the system, with the blood within, containing oxygen that is vital to the survival of an organism.
What nutrients does your circulatory need?
blood only carries our nutrients. nutrients are transported by blood.
What carries nutrients and oxygen through the blood?
A.blood
B.veins
C.arteries
D.lungs
The Answer is A
What year did William Harvey discover the circulatory system?
he discovered the circulation of blood been pumped around the body in 3 june 1657
How does poor nutrition effect the circulatory system?
It puts a strain on the heart because of all the extra miles of blood vessels it has to pump through.
What flows between the respiratory and circulatory system of the body?
oxygen is absorbed and carbon dioxide is released in lungs.so these gases are exchanged between circulatory and respiratory system.
What does the septum do in the circulatory system?
The septum is a partition which divides the heart into left and right. The right side gets all the impure blood from the body and this is pumped out to the lungs where it gets oxygenated or purified. This blood then returns to the left side of the heart and is then pumped out to supply the tissues. The septum therefore separates the deoxygenated blood from the oxygenated blood
go to doctor. that aint normal qurl.
What are the main organs in for the circulatory system?
Here's a little bit of physiology courtesy of kidshealth.org/teen/your_body/body_basics/heart.html:
The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body. It usually beats from 60 to 100 times per minute, but can go much faster when it needs to. It beats about 100,000 times a day, more than 30 million times per year, and about 2.5 billion times in a 70-year lifetime.
The heart gets messages from the body that tell it when to pump more or less blood depending on a person's needs. When we're sleeping, it pumps just enough to provide for the lower amounts of oxygen needed by our bodies at rest. When we're exercising or frightened, the heart pumps faster to get more oxygen to our bodies.
The heart has four chambers that are enclosed by thick, muscular walls. It lies between the lungs and just to the left of the middle of the chest cavity. The bottom part of the heart is divided into two chambers called the right and left ventricles, which pump blood out of the heart. A wall called the interventricular septumdivides the ventricles.
The upper part of the heart is made up of the other two chambers of the heart, called the right and left atria(pronounced: ay-tree-uh). The right and left atria receive the blood entering the heart. A wall called the interatrial(pronounced: in-tur-ay-tree-ul)septum divides the atria, and they're separated from the ventricles by the atrioventricular (pronounced: ay-tree-oh-ven-trik-yoo-lur) valves. The tricuspid valve separates the right atrium from the right ventricle, and the mitral (pronounced: my-trul) valve separates the left atrium and the left ventricle.
Two other heart valves separate the ventricles and the large blood vessels that carry blood leaving the heart. These valves are called the pulmonic valve, which separates the right ventricle from the pulmonary artery leading to the lungs, and the aortic valve, which separates the left ventricle from the aorta, the body's largest blood vessel.
