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.
The base of the heart is its blank surface?
Is it's posterosuperior surface. Made up of the left atrium for the most part, and also a bit of the right atrium. The left ventricle makes up the apex.
Who was the person that discovered the circulatory system lungs?
What are the differences between the systemic and pulmonary circulatory systems?
the heart has two systems, the pulmonary and the systemic system.the pulmonary is responsible for getting carbonated blood (blue) to the lungs to get loaded with nutrients and oxygen (see cellular respiration) and to take oxygen rich blood back to the heart. While the systemic system is responsible for taking oxygenated blood (red) from the heart to the rest of the body to diffuse the ATP (ATP = oxygen + nutrients from food. ATP is energy.) Then the carbonated blood (carbonated) returns to the heart to be sent back to the lungs.(pulmonary system)
What are the main organs of the male reprodutive system?
The vas deferens, prostate, bulbourethral gland, and seminal vesicles are the internal organs of the male reproductive system.
What will happen if the Circulatory System was damaged?
Any time a person bleeds, it is because of some severed blood vessel, usually capillaries. In most cases this has no effect on the heart. The heart is at risk only when its own blood supply is affected.
What does circulatory system do for respiratory system?
When respiration takes place, oxygen needs to be transported to all the body and for the deoxygenated blood to be cleaned. The heart cleans that blood as well as transport/delivers the oxygen and the cleaned blood called oxygenated blood.
This is what circulatory system do for respiratory system.
What are 3 types of circulatory shock?
Types of Shock:
Septic, from systemic infection
Hypovolemic, from fluid loss. Diarrhea, Burns
Hemorrhagic, from rapid bleeding either trauma internal bleeding such as GI
Cardiogenic, from pump (heart, mechanical) failure. MI CHF
Diabetic, not enough insulin to convert fat or glycogen to sugar
Anaphylactic, allergic reaction to peanuts shellfish bee sting
Neurogenic, spinal or brain injury causes blood vessels to relax and blood to pool in lower extremities.
Reasons why the circulatory system is important?
Um, the cardiovascular system is important to EVERYBODY, regardless of age. Your cardiovascular system is your HEART. You need a heart to LIVE.
What does lymph absolute number mean It is 3.8?
The reference range for Lymph Absolute is 1.9-8.0 for x10e3/uL. So 3.6 should be within normal range.
How does the digestive system and the circulatory system work in conjunction during digestion?
First, with the help of digestive system the food is broken down into smaller pieces which we eat and nutrients are separated which are further transported with the help of blood circulatory system.
Where does most absorption of the end products of digestion into the circulatory system?
In the small intestine
What are the factors that affect hemoglobin's affinity for oxygen?
The primary factor that determines how much oxygen is actually bound to hemoglobin is the partial pressure of oxygen (pO2) in the hemoglobin solution.
Where must blood go to get a fresh supply of oxygen?
The alveoli, or air sacs, of the lungs. Blood is returned by veins to the vena cava, and to the right atrium of the heart. The blood is pumped by the heart's right ventricle to the lungs through the pulmonary arteries. The pulmonary veins return the oxygenated blood to the left atrium, where it is pumped by the left ventricle into the body's arteries through the expanded artery called the aorta.
What do your body's cells do with the oxygen they receive?
The oxygen diffuses into the Red Blood Cells (RBCs) in the lungs. The blood goes to the heart and is pumped to the rest of the body. When the blood reaches oxygen deprived tissues, the oxygen moves from the RBCs to the tissues.
What statement correctly describes an interaction of the respiratory and circulatory systems?
The most direct stament that links the two organ systems is simple. When breathing, the oxygen travels down your trachea and into your lungs where it reaches tiny sponge like cells (avioli) covered with very small veins. Once the oxygen recahes there, transfussion occurs where the oxygen goes into the bloodstream and is replaced by carbon dioxide, which you breathe out
Why do you need your circulatory system to keep tissues all over your body alive?
as this gives oxygen to your lungs as you need air to breathe!
Oxygen is transfered into the blood at alveoli. Oxygen travels along the pulmonary vein into the left ventricle of the heart. It then travels along the aorta to the body tissues, gathering impure blood (CO2) along the way. Travels back to the heart via the Vena Cava and all impure blood is emptied into the right atrium of the heart, before it travels back to the lungs via the pulmonary artery.
What is a circulatory system doctor called?
Doctors who deal with the circulatory system are called Cardiologists or Vascular Surgeons, depending on the condition.
What material does the circulatory system transport through out the body?
The heart, lungs, veins, and arteries. The heart pumps oxegen rich blood into the arteries through the aorta. These arteries travel through out your body. After the O2 has been exchanged in the tissue (muscles, skin) it is passed into the veins. The veins carry the oxegen poor blood to the pulmonary vein. The pulmonary vein carries this "used" blood to the lungs. When you inhale, oxegen is mixed into the blood again. When you exhale, the lungs push the rich blood into the heart through the pulmonary artery and the cycle begins again.
How does smoking affect your circulatory system?
Smoking harms the Cardiovascular system by reducing levels of high-density lipoproteins ("good" cholesterol"), and raising levels of triglycerides and low-density lipoproteins ("bad" cholesterol"). It also increases blood pressure and heart rate, while reducing the amount of oxygen available to the body. It makes the platelets in blood become sticky, promoting clotting, and permanently accelerates the rate at which fatty deposits are laid down in arteries.

JOINT STATEMENT ON THE RE-ASSESSMENT OF THE TOXICOLOGICAL TESTING OF TOBACCO PRODUCTS"
7 October, the COT meeting on 26 October and the COC meeting on 18
November 2004.
"5. The Committees commented that tobacco smoke was a highly complex chemical mixture and that the causative agents for smoke induced diseases (such as cardiovascular disease, cancer, effects on reproduction and on offspring) was unknown. The mechanisms by which tobacco induced adverse effects were not established. The best information related to tobacco smoke - induced lung cancer, but even in this instance a detailed mechanism was not available. The Committees therefore agreed that on the basis of current knowledge it would be very difficult to identify a toxicological testing strategy or a biomonitoring approach for use in volunteer studies with smokers where the end-points determined or biomarkers measured were predictive of the overall burden of tobacco-induced adverse disease."
In other words ... our first hand smoke theory is so lame we can't even design a bogus lab experiment to prove it. In fact ... we don't even know how tobacco does all of the magical things we claim it does.
The greatest threat to the second hand theory is the weakness of the first hand theory.
Why do larger organisms need a circulatory system and amoeba do not?
We are eukaryote which means are cells are more advanced than there's. And since we have more cells than a amoeba. Our cells carry oxygen to the brain and other organs in the body. A amoeba dose not have a brain. So it doesn't need a circulatory system.
Do butterflies have closed circulatory systems?
The butterfly's circulatory system consists of a long tubular heart and hemocoel (spaces between organsfor blood to move). The blood is pumped out to tissues through the hemocoel, but it simply seeps back through the tissue, and it doesn't carry oxygen, just nourishment. Air enters through pores called spiracles and moves through tubes through the body, with gas exchange occurring at the ends of those tubes (tracheae).
