what is the partial pressure of oxygen and carbon dioxide in the blood?

PCO2 = 35-45\nPO2 = 75-100

The lungs (respiratory system) take in air (using the oxygen and breathing out the carbon dioxide), the heart pumps the oxygen through our arteries (circulatory system)making our blood red.

Blood contains hemoglobin, which enables blood to be transported through the body. The hemoglobin molecule has four sites for oxygen to attach.  When all four positions are filled, the hemoglobin is fully (100%) saturated.\n\nFor a person breathing room air, at not far above sea level, acceptable normal ranges are from 95 to 100 percent.

The partial pressure of O2 at 10 000 feet altitude.   Well, the air pressure at sea level is about 100 kilopascals.   At 10 000 feet it's about 70 kilopascals.   About a fifth of the air is oxygen so the partial pressure of O2 up there is about 14 kilopascals.

The body's circulation has two parts, with the heart acting as a double pump. Blood from the right side pump is dark red (bluish) and low in oxygen. It travels along pulmonary arteries to the lungs where it receives fresh supplies of oxygen and becomes bright red. It flows along pulmonary veins back to the heart's left side pump.\n\n \n\n \n\n\nBlood leaves the left side of the heart and travels through arteries which gradually divide into capillaries. In the capillaries, food and oxygen are released to the body cells, and carbon dioxide and other waste products are returned to the bloodstream.The blood then travels in veins back to the right side of the heart, and the whole process begins again.

Water and Carbon dioxide. With the help of an enzyme called carbonic anhydrase.

Well, oxygen is used for respiration, and carbon dioxide is only used for photosynthesis. Respiration should occur throughout the day for survival (duh), and photosynthesis can only occur when sunlight is present. So, the ans should be (c)

Nitrogen and oxygen make up around 99% of the total atm pressure. Carbon dioxide, water and other inert gases make up the other 1%. There is a graph called the Oxygen-Hemoglobin dissociation curve, and temp. carbon dioxide and blood pH can shift this curve to the left or right...increase in CO2 the curve shifts right, decrease it shifts left. So in tissues the CO2 levels are higher so the Red Blood Cells pick up CO2 easily and in the lungs the CO2 levels are lower than in the blood and O2 is picked up, and of course there is the Cl shift that occurs. CO2 is a byproduct of cellular respiration...energy production in the mitochondria...this is a long question to answer, there is more to it but I hope this helps.

PO2 must drop below 60 mm Hg for stimulation of peripheral chemoreceptors. Up to a PO2 of 60 mm Hg, Hemoglobin is still substantially saturated with O2 and adequate amounts of O2 can be delivered to tissues and the brain. Also, when PO2 drops from 100 - 60, usually there is also increased PCO2 levels. So, ventilation is usually increased due to response of central and peripheral chemoreceptors to increasing PCO2 levels.

Simple one will be \nSunlight + Carbon dioxide (CO2) + Water (H2O)--> Glucose (C6H12O6) + Oxygen (O2).\nor \n6CO2 +12 H2O (light energy and chlorophyll) ---> C6H12O6 + 6O2\nRemember to use subscript whenever necessary.

Carbon dioxide is not weightless\nIn fact is has \n\n12g in carbon, and in oxygen it has 12, but as there is 2 carbon atoms there is 16g in oxygen\n\nSo 12+16*2 = 44g.\n\nHow do i know this? Look at the periodic table.

Partial pressure is a way of adding up pressures of gasses in Chemistry.\n\nUsing the Ideal Gas Law (PV = nRT), one can find the pressures of, say, three different containers.  Each of these pressures is called a partial pressure.\n\nTo find the theoretical total pressure (pretending that all 3 gasses in the 3 containers were mixed into one container, whose volume is identical to the three added up), you add up the partial pressures.\n\n(**  )<|\nDead Fish\nOllec, the Fish Slayer

it happens , the partial perassure of o2 is less in cells than in hemaglobin so it diffusses in to cells frm hemoglbin

oxygen is removed and replaced by co2

It depends on the pressure and temperature. 50 lbs. of O2 represent a fixed number of moles of CO2. From the ideal gas law PV=nRT. Cannot solve for volume V without knowing P and T.

Oxygen and CO2 have different densities. Oxygen (density of 1.429 g/L) is at the top of the room...CO2 ( 1.98 kg/m³ density) ,settles.
