Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will combine with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body. One function of the blood is to transport materials within plasma and hemoglobin around the body. Plasma contains hormones, nutrients and waste substances.
(With resistance) Air: with resistance, syringe A can still be pushed a little towards syringe B. this is because particles in air are spread out; there are room in between to particles. That is why when syringe A is pressed down, the particles compressed together tightly causing the syringe to move a little before the particles were impacted too tightly for the syringe to move Water: water particles are different from gas particles. Water has very little compressibility. Particles in water are much more compacted together, therefore giving no space for them to compress more. This is the reason why with resistance, syringe A will not move as the particles in water are as tightly compressed together as they can get.
(Essentials of Anatomy & Physiology, Chapter 15, 504-511) 2. Gas exchange within the lungs and body tissues is vital for life to exist. Briefly explain the gas exchange that occurs in the lung tissue and body tissue for oxygen and carbon dioxide. What is the driving force for this movement of gas (think concentration gradient)? Finally, how does carbon monoxide disrupt the process of oxygen transport?
Vegetable oil is hydrophobic and there for is not water soluble but alcohol on the other hand is completely soluble with vegetable oil. 3. We know from observing the vegetable oil and water together that the relative density of water is greater then the density of vegetable oil because the oil will always recede to the surface of water. 4. Emulsification agents allow for two unbendable liquids to be combined, the detergent hold properties that both substances can in return blend with leaving detergent dissolving in both the water as well as the alcohol unlike other substances we tried to
SCIE 207 Phase 1 Lab Report Michael Freeman SCIE207 3/29/15 Lee Ott SCIE 207 Phase 1 Lab Report I was observing the bubbles and came to a conclusion. It seems to me that the more heat that was put to the water the more oxygen it created. With more oxygen we will have more bubbles. When we decide to put more heat to the water the more the water wants to boil, in turn that will create more bubbles of oxygen. Because these processes cannot be observed by the naked eye, it is difficult for many individuals to conceptualize.
Electrons can now continue to move through PSII and the cytochrome b6 f complex, and oxygen is produced in the water-splitting reaction. 34. Bioenergetics of Photophosphorylation The steady-state concentrations of ATP, ADP, and Pi in isolated spinach chloroplasts under full illumination at pH 7.0 are 120.0, 6.0, and 700.0 mM, respectively. (a) What is the free-energy requirement for the synthesis of 1 mol of ATP under these conditions? (b) The energy for ATP synthesis is furnished by light-induced electron transfer in the chloroplasts.
If a tracheostomy bypasses the upper respiratory passages, how might the air entering the trachea differ from air normally passing through this tube? What problems might this cause for the patient? There is less mucus membrane exposure since the nose is being bypassed the air wont be filtered as well. There is no significant difference. 5.
As a person breathes in and out, the sacs become bigger and smaller to move air through the lungs. When these sacs are damaged they stretch making less air come in and out of the lungs. Inside of those alveoli's this is where the blood is exchanging carbon dioxide, for oxygen. When the sacs become larger they move less oxygen in the blood. Which causes short of breath.
Atelectasis affects the exchange of oxygen and carbon dioxide in your lungs, which can lead it to become a very severe problem if one develops it (Mayo Clinic Staff). Lack of deep breaths will result in decreased secretion of surfactant into alveoli in some areas. Decreased level of surfactant leads to collapse of the alveoli (atelectasis). When alveoli collapse, there is less surface area for diffusion of oxygen into the bloodstream. When enough alveoli are atelectatic, oxygen delivery will be reduced.
Erythrocytosis/Polycythemia A. What Is Erythrocytosis? Erythrocytosis is defined as an excess of erythrocytes, or red blood cells (RBCs). RBCs carry oxygen to the body. When RBC levels are low, the body’s tissues cannot obtain enough oxygen.
