Circulatory System

if you mean the "respratory system" that is the cycle of breathing but if you are inquireing the "resperation system" im not really sure...

b. germinal centres

c. medullary cords

d. sinuses

name one quantity that must be known in order to determine the amount of heat associated with the body

One is your hart

The splanchnic circulation is a particular bloodflow. It moves through the regions of the stomach, small intestine, colon, pancreas, and spleen.

Vena cava>right atrium>right ventricle>pulmonary artery>pulmonary vein>left atrium>left ventricle>aorta

if we consider the formation of RBCs Erythropoietin, produced by the kidneys, signals RBC formation in the red bone marrow is required.

but if we consider the activation of rbc so haemoglobin is essential, in which haemoglobin consiats of single molecule so we can also say for the activation of rbc that:-

IRON------>HAEMOGLOBIN------>RBC

and RBC are produced as

BY KIDNEY------->ERTHROPROTEIN------>RBC

==new answer== There are many different ways of thinking that we need to become acquainted with and find the most productive use for. You have daily opportunity to see how these ways of thinking are reflected through other people in your experiences. Look to find a new quality in yourself each day to explore. Practice being who you want to become and your understanding of yourself will grow. Never compare yourself to another, since we are all unique, with different understandings and different experiences.

The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.

the system that circulates blood and lymph through the body, consisting of the

• heart
• blood vessels
• blood
• lymph
• lymphatic vessels and glands.

A four chambered heart establishes two distinctly separate circulatory pathways. Pulmonary circulation carries blood from the heart to the lungs and back. Systemic circulation carries blood from the heart to all other areas of the body and back. To have separation of these pathways by a second ventricle insures no mixing of oxygenated blood (from the lungs) with de-oxygenated blood (from all other parts of the body). Pumping blood to all parts of the body with a higher concentration of oxygen would enable tissue to produce more energy which could sustain a higher level of activity and allow warm blooded animals to evolve (birds and mammals).

Yes

Carbon dioxide- Breathing

Lactic Acid- Excersize burns off lactic acid. ( The reason your muscles cramp after you work out is due to a build up of lactic acid, it may be painful, but if you run more or stretch it gets rid of the spare lactic acid.

People who do a lot of exercise can have larger hearts because the heart muscle like any other muscle grows the more it is used. An enlarged heart can also be a sign that there is some other problem with the circulatory system, which means that the heart is having to work harder than normal to compensate, and the heart muscle will grow for the same reasons as when it works harder in exercise.

The cells of the heart are supplied with blood through the hearts own artery. The artery that supplies the heart blood is known as the coronary artery.

This system contains the heart, arteries, veins and capillaries.

Firstly Are u sensible enough to understand the answer of this question?

If yes then open ur Biology book and go through the respective chapters.

Then use your common sense to connect the dots.

ta dah! There you go now you the answer to your question.

p.s. If u are not in the possession of a biology book, jst use your younger siblings, better yet ask them this question. Surely they'll know d answer.

His major original contribution of great significance was his discovery of the blood's circulatory system, which was discovered again by modern science after a lapse of three centuries. He was the first to correctly describe the constitution of the lungs and gave a description of the bronchi and the interaction between the human body's vessels for air and blood. Also, he elaborated the function of the coronary arteries as feeding the cardiac muscle. Hope this helps.

SA = System Annoyance

The atria are a part of your heart which is in the circulatory system
