The answer should be C, It diffuses from the alveoli into the blood.
Alveoli, also called the air sac, is the place where the oxygen we breathed in is exchanged with carbon dioxide that our body produces. Oxygen is passed into the blood in the capillaries through the process of diffusion, while carbon dioxide is diffused from the blood back to the alveoli, so that we can exhale the carbon dioxide after that.
Both a and b are not right because when we breathe in, the oxygen travels from the trachea to the bronchi, to the bronchiole, and to the alveoli, instead of directly into blood vessels like arteries, capillaries, or veins. d is also not right because the direction is wrong.
Therefore, your answer should be C.
The given diagram represents Metaphase and Anaphase on the left and right sides respectively, which occur during mitosis.
The diagram depicts two phases, i.e. Metaphase as well as Anaphase, which are observed during the process of mitosis. Mitosis can be defined as a type of cell division where a particular cell (parent cell) undergoes division in order to give rise to two new cells (daughter cells). These newly formed cells are genetically similar to the parent cell.
During Metaphase, the chromosomes appear to be arranged in the central region of the cell in a linear fashion. During Anaphase, the chromatids segregate from each other and progress towards opposite ends of the cell undergoing mitosis.

Answer:
Two ureters.
These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys. If urine backs up, or is allowed to stand still, a kidney infection can develop.
