Circulatory System

The brain, the eyes, hearing, internal organs, skin, nearly everything in the body can be negatively affected by long term bouts of high blood pressure.

no, it's a brownish pink, and does not look like normal period blood.

cardiac muscles

A good and simple analogy for the circulatory system is a system of roads and towns.

The main blood vessels are the motorways; the capillaries can be compared to rural country lanes. The blood cells can be compared to vehicles: red blood cells to trucks and lorries (carrying oxygen and carbon dioxide), white blood cells are best compared to police cars (protecting us from harm!). Towns, cities, villages and buildings which are passed by the vehicles represent the body cells and organs that our red blood cells unload their oxygen or CO2.

This isn't a foolproof analogy, but it is a decent attempt at relating in layman's terms the function of the circulatory system.

the routine measurements that could be taken to monitor the functioning of asthma is peak flow measurement.

Blood is forced into the ventricles each time the atria contact.

*do you go to Smith Language Academy because we had the same question on our extra-credit. :-)

When muscles are used for exercise, they must be replenished with oxygen, nutrients, etc. They also produce waste products that need to be taken away from the cells. Blood is the transport system for all of these things, so the harder your muscles are worked, the quicker they burn through nutrients and produce waste, meaning that the blood must flow faster to provide all of this; the only way for blood to flow faster is for your heart to beat faster.

Resting muscle gets about 750 ml of blood out of your 5 liters of cardiac out put. During exercise the cardiac output may go up to 25 liters per minute. Out of these 25 liters of cardiac out put, your muscles get about 20 liters of blood to meet the metabolic requirements of oxygen and food material. The stroke volume of heart increases but then heart rate also increases from 72 per minute to up to 180 beats per minute.

Yes, but if you increase the speed of your breathing too much you can hyperventilate and / or pass out.

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

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.
