The lymphatic vessels are thin-walled valvular structures, composed of lymphangions, which carry the lymph from the tissues, via the lymph nodes, to the bloodstream. For this reason, they are analogous to veins and venules.
The lymphatic network is present throughout the body with the exception of the central nervous system and non-vascularized tissues.
It is separated in two circuits: one for the upper right quarter of the body, and one for the rest.
The lymphatic channels join together to form lymphatic vessels more and more voluminous.
Finally, The lymph is drained by two large collectors:
* The right lymphatic canal
* The thoracic duct.
All lymphatics thus end up in the upper vena cava system by two separate circuits.
False unlike the outer core the inner core is made out of mostly solid because it contains iron
<h3><u>Expansion of energy in active transport:</u></h3>
- Active transport is a transport process that involves movement of molecules between regions through a membrane against the concentration gradient.
- It is homeostatic process which means it’s a biological process in which functions of the body are regulated to achieve internal balance.
- Active transport uses metabolic energy ATP to transport molecules across a membrane.
- Generally, metal ions are transported across cell membrane by active transport.
- Metal ions are transported with the help of ion pumps and are distributed through the body.
Answer;
Nasolacrimal duct
The runny nose you get when you cry is a result of your tears draining into the nasolacrimal duct.
Explanation;
The nasolacrimal duct is the duct that carries tears from the lacrimal sac of the eye into the nasal cavity.
Tears normally drain through small openings in the corners pf the upper and lower eyelids called puncta and then enters the nose through the nasolacrimal duct.
The puncta and the nasolacrimal duct are part of the nasolacrimal drainage system.
