B. When his heart struggle to work with the life giving blood slowed along with the oxygen, glucose and essentials ions it carried to pump the heart, each cell continues working and rapidly using it ATP supply, so when the carbon dioxide level cells rise inside the cell the PH drops and the mitochondria no longer has enough oxygen to make ATP energy which allows the cells to begin to die. The cells become leaky, sodium slowly…
When carbon dioxide (CO2) mixes with water in the blood stream, carbonic acid is formed. This carbonic acid can then dissociate into the _______ ion and the _______ ion.…

The solution of salts inside the cell are hypertonic in comparison to that of the blood stream so therefore the salts move through the semipermeable membrane of the cell to the less concentrated blood stream.…
Every cell is selectively permeable to different molecules. This type of selectively is caused by a semi-permeable membrane, which allows the movement of certain molecules across it. Water exchange can be measured in two ways: RBC osmotic permeability is measured, and diffusional water permeability is measured (Benga and Borza 1995). Diffusion is the movement of high concentration to low concentration. The diffusion of water across a permeable membrane is called osmosis. Water concentration in red blood cells can cause three different situations: hypertonic solution, isotonic solution, and a hypotonic solution. A hypertonic solution is when there is a higher concentration of salts dissolved outside the cell and pure water inside the cell, the water rushes out of the cell to try to dilute the salt solution causing the cell to shrivel up. An isotonic solution is where the water has achieved equilibrium with concentrations inside and outside of the cell, so there is no alteration of the cell. A hypotonic solution is where there is a higher concentration of salt dissolved inside the cell and a higher concentration of water outside the cell, so the water rushes into the cell trying to dilute it causing swelling of the cell. If this takes place too rapidly, it will lead to the cell bursting. Knowing the isotonic solution of red blood cells is important in many ways such as filtration because the membranes flux causes the cell to become larger or smaller so if it is too large it can not be filtered through certain size capillaries (Tuvia 1992). Also, red blood cells can only operate in an isotonic state, in a hypotonic solution the cell bursts leaving no cell at all, but in a hypertonic solution the cell shrinks, which decreases the surface area and its viability to uptake oxygen leaving it ineffective for its purpose. To measure the size and amount of red blood cells in each concentration of solutions, a hemocytometer was used.…
When pH is low, hydrogen ion levels in the blood are high and also in the interstitial and peritubular fluid. Hydrogen ion competes with potassium ion for the sodium countercurrent exchanger in the tubules. As hydrogen ion secretion rises (which compensates for the…

Decides the development of CO2 and O2 amongst air and lungs, amongst lungs and blood, and amongst blood and body cells.Blood gets to be acidic when there is an expansion in CO2 content (this relationship will be portrayed further amid your class on blood-gas examination). Since hemoglobin can tie CO2 to its heme bunches and additionally oxygen, the two go after the heme restricting destinations and the intensify that is in higher focus will by and large win out. This is uplifting news for dynamic muscles amid activity…

The pH level in the blood is maintained by the kidneys and the lungs. The pH level on the blood should be at 7.4. In order for the kidneys and lungs to maintain this pH level it affects the buffers in the blood. The buffer is a substance that is resistant to the change in the body’s pH level. Basically the buffers can make an acid or base less potent and try and neutralize it so the body is not overly acidic or basic. When these buffers attach to the acidic molecule they act to reduce how strong that molecule is. When the buffers attach to the base molecules it does the same thing to try and lower the strength of the base. All in all the buffers work to keep both acids and bases at a neutral level.…
Once the red blood cell returns to the heart, it enters through the vana cava (vein) returning the deoxygenated blood from the upper part and the lower parts of the body to the heart. This large veins lead into the right atrium where the pumping heart forces the red blood cells through the tricuspid valve into the right ventricle. The valve stops blood from flowing backwards into the right atrium once it’s in the right ventricle they are then pumped through the pulmonary valve into the pulmonary artery and on to the lungs. The arteries carry blood away from the heart (always oxygenated apart from the pulmonary artery which goes from the heart to the lungs), they have thick, elasticated, muscular walls which allows them to expand (creating pulse) and to deal with the high blood pressure. Once the blood is delivered to the lungs via the capillaries (found in the muscles and lungs, microscopic – one cell thick blood vessels which are also very narrow to create very low blood pressure- adapted to maximise diffusion of gases) within the alveoli, an exchange of gases takes place between the gases inside the alveoli and the blood.Blood arriving in the alveoli has a higher carbon dioxide…
They play an integral role in the following functions: Organization/ Comprehension of language, Information Retrieval (Memory and Memory Formation), Senses of smell and sound, as well as processing of complex stimuli like faces and scenes, memory and understanding language. The primary auditory cortex is responsible for hearing and primary olfactory cortex is responsible for interpreting the sense of smell once it reaches the cortex via the olfactory bulbs.
