Answer:
Those capillaries that have endothelial cells tightly attached have an increase in cell-to-cell junctions, such as desmosomal junctions that are poorly permeable to substances.
These capillaries generally function as conductors or collectors and not as permeabilizers like the pulmonary capillaries that are fenestrated and allow a high passage of substances and gases.
The capillaries are waterproof and prevent the passage of substances or fluids such as in the blood-brain barrier that is very selective
Explanation:
The blood-brain barrier is too selective since it is not favorable for the organism that many fluids, drugs, substances or chemical compounds enter the brain space.
This is the reason why the vessels are waterproof and why pharmacology was challenged to invent drugs that could cross this barrier since it was considered impossible.
An example is dopamine, which in parkynson's disease the levo group is added to dopamine, thus forming levodopamine as a product, this is the only way that the drug crosses the blood-brain barrier and can pass the impermeable barrier generated by capillaries with endothelial cells that are close to each other or closely linked
Hihi!
There are seven characteristics of living things: movement, breathing or respiration, excretion, growth, sensitivity, and reproduction! But sadly as for non-living things they lack most of these things. Their characteristics are that <span>they lack the </span>capability<span> for </span>growth<span>, </span>reproduction, respiration<span>, </span>metabolism<span>, and </span>movement<span>. They also cannot </span><span>respond to a stimuli and they also cannot</span><span> evolve and adapt to their environment. Isn't that kind of sad?

The plane(s) of the section that would allow me examine the internal anatomy of both lungs at the same time are as follows;
- Sagittal
- Coronal
- Transverse
<h3>What are body planes?</h3>
Body planes are imaginary geometric planes that are used to divide the body into pieces. They are used to analyze interior organs and systems during anatomical procedures.
We have the following body plane types:
- Any vertical plane that separates the body into anterior and posterior halves is referred to as a coronal plane.
- Any plane that separates the body into superior and inferior halves and is nearly perpendicular to the spine is referred to as a transverse plane.
- Any imaginary plane parallel to the median plane is referred to as the sagittal plane.
Based on the three types of plane sections we have, the plane(s) of the section that would allow me examine the internal anatomy of both lungs at the same time are as follows;
- Sagittal
- Coronal
- Transverse
