Answer:
pulmonary ventilation and external respiration
Explanation:
Respiration includes pulmonary ventilation, external respiration, and internal respiration. Pulmonary ventilation is also called breathing and is the process of flow of air into and out of the lungs. It includes the flow of air between the atmosphere and the alveoli of the lungs and is driven by alternating pressure differences created by contraction and relaxation of respiratory muscles.
External respiration is also called pulmonary respiration. It refers to the exchange of gases between the alveoli of the lungs and the blood in pulmonary capillaries. The exchange occurs through the respiratory membrane. External respiration males the capillary blood rich in O2. The capillary blood loses CO2 during the process.
Answer:

- intracellular space is absent
- Cells are oval, rounded or polygonal in shape.
Answer:
Explanation:
By maintaining amount of ions in the blood.
Countercurrent flow met the goals due to difference in concentration gradient.
Explanation:
Diffusion restored homeostasis during the dialysis treatment because during dialysis, the concentration of ion in the blood is maintained that leads to homeostasis.
Countercurrent flow met the goals because it flows in opposite direction while on the other hand, parallel flow did not meet the goals because it flows in the same direction. For example. the blood flows in one direction and the dialysate flows in the opposite direction. The countercurrent flow of the blood and dialysate increases the concentration gradient between the blood and dialysate. The increased gradient helps to remove more potassium, phosphorus and urea from the blood. If we used parallel flow so less concentration gradient of solutes is present and hence, less potassium, phosphorus and urea are removed from the blood
The main reason that attitudes are more often revealed in spoken rather than written language is because in writing, we can easily conceal our attitudes. The correct answer is D.
