Circulatory System

respiration

The pleurae cover each lung and line the inner surface of the thoracic cavity. The pleura that encloses the lung is called the visceral pleura. The pleura that lines the thoracic cavity is the parietal pleura.

The loss of the nucleus is all part of the red blood cell's adaptations for its function of carrying oxygen around the body. Each cell is packed with a protein called hemoglobin, which attracts oxygen very strongly when blood flows through the lungs, so can carry as much oxygen as possible.

Its other adaptation to its function is that it has a biconcave shape - this enables it to have a large surface area for picking up oxygen in the first place.

During their maturation in mammals, a red blood cells loses its nucleus, mitochondria and endoplasmic reticulum, which makes them inactive metabolically.

The pulmonary system is connected to the pulmonary system in two ways. First the circulatory system does the same for the pulmonary system as it does for every other part of the body -- it supplies food and oxygen and removes waste products and CO2. But, in addition the heart pumps blood through the lungs to remove CO2 and pick up oxygen.

I think it is Respiratory System...

Heart > artery > arteriole > capillary > venule > vein > heart

You could say veins, arteries, and capillaries, or heart, blood, and blood vessels, or pulmonary circulation, coronary circulation, and systemic circulation.

Right heart - lungs - left heart - arteries - capillaries - veins - (begin again).

Absorption is the process that allows food to move from the small intestine to the blood stream. Absorption is critical because it allows the nutrients to be used by cells throughout the body.

This has to do with acid-base homeostasis. Normal blood pH is 7,4.

- Alkalosis = pH >7,4

- Acidosis = pH <7,4

Then you have 2 types for each one, respiratory or metabolic.

- Respiratory alkalosis = CO2 <40mmHg

- Respiratory acidosis = CO2 >45mmHg

- Metabolic alkalosis = HCO3- >26mEq

- Metabolic acidosis = HCO3- <22mEq

If your breathing rate goes beyond 20 per minute (hyperventilation), CO2 goes down and pH goes up. Then your body compensates this by losing HCO3- in the urine, lowering the pH.

If your breathing rate slows down below 15 per minute (hypoventilation), CO2 goes up and pH goes down. Then you reabsorb more HCO3- in the kidneys, raising the pH.

If your kidneys start malfunctioning, your body can't excrete acid compounds and HCO3- gets consumed, then the pH goes down. Your breathing rate goes faster in order to excrete more CO2, raising the pH.

And in some cases the kidneys reabsorb more HCO3- than they should, and pH goes up. Then your breathing rate slows down, CO2 goes up and pH goes down.

In some cases, pH can vary due to other reasons, such as diabetes or diarrhea, which can produce acidosis, or severe vomiting, that produces alkalosis. These are classified as metabolic as well, but can be regulated both by the respiratory and the urinary system, though the latter is rather inefficient in these cases.

what is the role of the brain in the curculatory system

When you breathe in air it goes in your lungs and the oxygen diffuses into the blood stream via the capillaries. Then the oxygen is carried throughout your body as needed.

To ensure that blood cells have just the right required amount of water content for them to be healthy. If they contain too much water, then this will pass through the cell's semi-permeable membrane out into the plasma; if they have too little, then the same will happen in reverse.

The digestive system absorbs the glucose in the small intestine. Then the glucose is now in the blood stream. The respiratory system needs the glucose to make energy. The circulatory system gets the oxygen pumped into the body. And now there are glucose and oxygen in the bloodstream. Now the respiratory system, the glucose and the oxygen react with each other and there is now energy.

All of the chambers of the heart work to circulate blood throughout the body. Below is the process of how blood circulates thru the heart. Blood will come in from either the Superior or Inferior Vena Cava. This will put blood into the Right Atrium. Goes thru the bicuspid valve into the Right Ventrical. Thru the pulmonary(semi-lunar) Valve into the Pulmonary Vein to the lungs. The Pulmonary Artery brings the blood back and puts it into the Left Atrium. Flows thru the Tricuspid (Mitral) Valve into the Left Ventrical. Flows thru the Aortic Valve into the Aorta and to the rest of the body.

The circulatory system transports nutrients, gases, liquids, and heat around the body. It also circulates and carries these around the body.

The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's way of getting oxygen to the blood.

slacker!

It is basically how your body works

The major componets of the circulatory system....

are the Heart, the Blood, and the Blood Vessles.

These major componets are vital in the process to escort oxygen to your lungs, and to your billions of blood cells.

It helps the cell by making sure everything gets circulated throughout the cell.

the heart pumps blood and oxygen to the muscles so they work!

Atherosclerosis is the disease of MODERN life style. What you have to avoid is not to be overweight. (Muscles are allowed and not Fat.) ALL animal Fats are bad for health as they are saturated. You have to use vegetable oils, witch are polyunsaturated. And you should have a brisk exercise,(Like running.) witch will take your pulse to 160 to 180/ minute for about 5 to 10 minutes(Even twice a week, if you are lazy.) will maintain elasticity of blood vessels and forget all diseases of blood vessels.( Even if you are slightly overweight.)

well it is all connected so co2 gets around your body as you do exercise because your breathing much faster. lol
