How does the blood moves around the body?
The blood moves around the body mainly through the beating of the heart. There are two main pathways, one is the pulmonary circuit that brings blood that has more carbon dioxide (deoxygenated) to the lungs to pick up oxygen, and the other is the systemic circuit that brings blood that has more oxygen (oxygenated) to all the rest of the body tissues.
3 Explain the purposes of inductive and deductive reasoning in mathematics?
In mathematics, deductive reasoning is used in proofs of geometric theorems. Inductive reasoning is used to simplify expressions and solve equations.
Where in your circulatory system do you think your blood pressure is highest lowest?
In general blood pressure is lowest in the pulmonary system, meaning from the pulmonary trunk through the lungs and back to the heart. The systemic system has a higher blood pressure since it must flow to all parts of the body. That being said all veins also have a lower blood pressure as well, when compared to the arteries and arterioles.
Does the queen have blue blood?
According to history, only the direct elder descendants of the 'Blood Royal' are the recipients of blue blood and therefore Queen Elizabeth does NOT have blue blood. According to tradition those named King or Queen were deemed to be blue blooded, i.e. Jesus Christ the King.
The lub-DUB of the heartbeat is caused by the closing of two separate pairs of valves, in response to heart muscle contractions. Turbulent blood flow occurs as blood pushes against the valves.
The first sound is caused by the closing of atrioventricular valves (mitral valve, tricuspid valve) that separate the upper chambers (atria) and lower chambers (ventricles) of the heart, as blood enters the ventricles.
The second sound is caused by the closing of the semilunar valves at the exit of the ventricles (the right ventricle having pumped blood into the pulmonary artery and the left ventricle having pumped blood into the aorta).
There are other specific heart sounds that occur, usually as a result of problems with the function of the heart.
What does the renal system do?
Renal System includes the kidneys which filters toxins out of the bloodstream
------------------------------------------------------------------------------------------------------
The Renal System removes excess water from the blood and filters the blood, removing the waste products of cell metabolism and passing this out of the body along with the excess water. Thus the system keeps the blood clean and maintains blood plasma volume and osmotic potential.
How do excretory and circulatory systems work together?
The circulatory system moves the blood around the body. Some of this blood passes through the kidneys, liver, lungs, and skin. Each of these organs performs some waste removal function on the blood. The simple answer would be that the circulatory system provides the excretory system with the blood to be cleaned. One thing that has always bothered me about the excretory system is that there is no system provided to ensure that all blood is cleaned at some point. The body seems to rely on the fact that mixing all the blood up together and cleaning some of it will make all of it clean enough for re-use.
circulatory system transports blood to and fro the excretory system.
What is the structure of the circulatory system?
transport oxygen, nutrients, and wastes; fights infection; helps regulate body temperature
heart, veins, capillaries, arteries . what is the function of these
During the hemorrhage what happens to the heart with regard to the circulatory system?
Your hear rate increases because it is trying to pump out more blood.
What are the blood clotting factors plasma proteins and cells fragment called?
Injury causes damaged tissue cells to produce prothrombin activator. This, along with a clotting factor produced by the sticky platelets (cell fragments) at the damaged site, cause prothrombin + calcium to make thrombin (blood protein). All the while fibrinogen is stimulated to make fibrin (blood protein). The fibrin ensnares RBCs to form the clot with the platelets.
All factors have to be there for the clotting to occur. Lack of any of them causes bleeding disorders.
What are the vessels pertaining to the ileum and the colon?
The superior mesenteric artery supply the from the second part of duodenum to two third of the transverse colon. This include the entire small intestine. The inferior mesenteric artery supply the rest of the colon to upper part of the rectum.
Explain the close relationship between the respiratory system and the circulatory system?
The circulatory system and respiratory system are interlaced. The circulatory system much deliver nutrients to all the parts of the body. Every single part of the body needs oxygen, so the circulatory system takes the oxygen collected by the respiratory system and delivers it to the rest of the body.
Are thin people more at risk for heart attack?
Thin people are at less risk for a heart attack. The main cause of a heart attack is when a plug of fat lodges in an artery that nourishes the heart. Thin people have less fat. They usually have less fat (actually ldl cholesterol or triglicerides) than fat people.
What system transports food oxygen and waste from all others?
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.
How do blood and lymph improve the skin and muscle condition?
improved circulation keeps subdermal tissues healthy (vital nutrients), hydrated (proper tonicity), and supple (correct cell junctions).
Dextrocardia
Think of the words logically and with common sense. Circulatory: deals with circulation, think of it as the flowing of something: Energy, Blood.
Problems is self explanatory.
So circulatory problems are issues with circulation. Maybe not enough blood getting to your legs for example.
How do the respiratory and circulatory system work together to make a person breathe in and out?
They don't. The CNS, muscular, and skeletal systems do.
