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.
There are three types of blood vessels; arteries, veins, and capillaries. Capillaries are tiny blood vessels.
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.
