Answer: digestive and excretory completes the sentence.
Answer: In order to compensate for the low partial pressure of oxygen at altitude, the human body undergoes a number of physiological changes. A vital component in this process is the increase in the concentration of circulating haemoglobin. The role of HIF‐1α, erythropoietin and red blood cells in this acclimatisation process is described, together with the fall in plasma volume that increases the concentration of haemoglobin in the early stages of hypoxic exposure.
Explanation:
Hypovolemic shock is caused by severe blood and fluid loss, such as from traumatic bodily injury, which makes the heart unable to pump enough blood to the body, or severe anemia where there is not enough blood to carry oxygen through the body.Hypovolemic shock is caused when there isn't enough blood in your blood vessels to carry oxygen to your organs. This can be caused by severe blood loss, for example, from injuries. Your blood delivers oxygen and vital nutrients to your organs
To give evidence supporting the writer's belief.
Great question. Cardiovascular endurance is how efficiently you heart, blood vessels, and lungs to supply oxygen rich blood to working muscles during physical activity (aerobic activity like walking, running, cycling or playing a sport) for a prolonged period of time or for more than 90 seconds.
