A tiny blood cell typically refers to a red blood cell, or erythrocyte, which is responsible for transporting oxygen from the lungs to the body's tissues and returning carbon dioxide for exhalation. These cells are characterized by their biconcave shape, which increases their surface area for gas exchange. Red blood cells lack a nucleus and organelles, allowing for more space to carry hemoglobin, the protein that binds oxygen. In addition to red blood cells, the bloodstream also contains white blood cells and platelets, each playing crucial roles in the immune response and blood clotting, respectively.

The smallest blood vessels are called capillaries.
White blood cells, red blood cells, and platelets.
The capillary is the only blood vessel where things can be exchanged because it is so thin (one cell thick). Capillaries have a single cell layer of squamous epithilium.
capillaries
These tiny air sacs are called alveoli. These alveoli are surrounded by capilaries tiny blood vessells. These capilaries have holes that are to small for blood cells to escape but are big enogh for oxygen molecules to pass in to the blood stream and attach to the haemoglobin in your blood.
A tiny organ in a cell is called an organelle.
No. They are called alveoli. Lymphocytes are a type of white blood cell.
Organelles are tiny cell sized organs. The substance that runs through these tiny cell sized organs are commonly called sub-units.
Why are nephrons surrounded by many tiny blood vessels
These tiny structures are called organelles.
This cell is a red blood cell, also known as an erythrocyte. Its small size and biconcave shape help to increase its surface area, allowing for efficient gas exchange of oxygen and carbon dioxide. This shape also enables the cell to deform easily as it passes through tiny capillaries without getting stuck.
There are three types of blood vessels; arteries, veins, and capillaries. Capillaries are tiny blood vessels.
