Answer:
If red blood cells are placed in a hypertonic solution, they will shrink because the water moves out of the cell through osmosis. When red blood cells are places in hypotonic solution they swell and rupture because the water moved in the cell through osmosis.
Explanation:
If red blood cells are placed in 1400mOsm of NaCl, the cell volume will be lost because the wayer in the cell moves out due to higher concentration of salt outside, they will shrink.
Similarly if the red blood cells are places in urea and NaCl the cell will again shrink.

one of the spleen's major jobs is filter the blood.
Explanation:
One of the spleen’s main jobs is to filter your blood. It affects the number of red blood cells that carry oxygen throughout your body, and the number of platelets, which are cells that help your blood to clot. It does this by breaking down and removing cells that are abnormal, old, or damaged.
The spleen also stores red blood cells, platelets, and infection-fighting white blood cells.
The spleen plays an important role in your immune system response. When it detects bacteria, viruses, or other germs in your blood, it produces white blood cells, called lymphocytes, to fight off these infections.
