Carbon Dioxide
Carbon dioxide (along with any dissolved gases) are transported through the blood to the lungs.
During respiration, oxygen enters the body through the respiratory system (nose/mouth) and travels down the trachea into the lungs. In the lungs, oxygen is taken up by red blood cells in the alveoli and transported through the bloodstream to body tissues where it is used for cellular respiration. Carbon dioxide, a waste product of cellular respiration, is then transported back to the lungs and exhaled.
The gaseous by-product of cellular respiration is carbon dioxide (CO2). It is produced during the breakdown of glucose in the mitochondria of cells and is released into the bloodstream to be transported to the lungs and exhaled from the body.
Oxygen is transported in the blood by binding to hemoglobin in red blood cells, while carbon dioxide is carried in the blood as bicarbonate ions dissolved in plasma. Oxygen is transported from the lungs to tissues for cellular respiration, while carbon dioxide is produced during cellular respiration and transported back to the lungs for exhalation. Oxygen is inhaled through the lungs, diffuses into the blood, and is delivered to tissues, whereas carbon dioxide is a waste product produced by cells and transported in the blood to the lungs for exhalation.
lungs
The lungs perform the following cellular respiratory processes - pulminory ventilation external respiration internal respiration
Carbon dioxide is the waste substance that is transported back to the lungs from the cells in the body. It is exhaled out as a waste product of cellular respiration.
Oxygen is transported by blood from the lungs to tissues primarily by binding to hemoglobin in red blood cells. Hemoglobin carries oxygen from the lungs to tissues where it is released for cellular respiration. Through this process, oxygen diffuses from high concentrations in the lungs to areas with lower concentrations in the body tissues.
The initial site for respiration is in the lungs, where oxygen is inhaled and carbon dioxide is exhaled. Oxygen enters the bloodstream through tiny air sacs called alveoli in the lungs, where it is then transported to cells throughout the body to support cellular respiration.
Breathing is connected to cellular respiration through the exchange of gases in the lungs. When we breathe in, oxygen is taken in and transported to the cells in the body. In the cells, oxygen is used in the process of cellular respiration to produce energy in the form of ATP. This process also produces carbon dioxide, which is then exhaled when we breathe out. So, breathing brings in oxygen needed for cellular respiration and removes the waste product, carbon dioxide.
No, cell respiration takes place on a cellular scale - within all cells.
Arterial blood contains the most oxygen in the body. It is transported from the lungs to various tissues and organs in the body, delivering oxygen for cellular respiration.
Oxygen is transported in the human body by binding to hemoglobin in red blood cells. Hemoglobin carries oxygen from the lungs to tissues in the body, where it is released for cells to use in cellular respiration. The carbon dioxide produced is then transported back to the lungs to be exhaled.
