Answer:
Thoracic duct.
Explanation:
Thoracic duct is the larger of the two lymph ducts of the lymphatic system. It is also known as the left lymphatic duct, alimentary duct, chyliferous
The thoracic duct is the largest lymphatic vessel within the human body, and plays a key role in the lymphatic system. It is also called the left lymphatic duct or the alimentary duct. A large portion of the body's lymph is collected by this duct and then drained into the bloodstream near the brachiocephalic vein between the internal jugular and the left subclavian veins.
The typical length of this duct in an adult averages between 38 and 45cm, while the diameter is about 5 to 7 mm. It originates from the second lumbar vertebra level and goes to the neck's root. The duct arises from the combination of the left and right lumbar trunks and the intestinal trunk in the abdomen.
It transports up to four liters of lymphatic fluid each day. This process is primarily caused by the breathing action and is assisted by the smooth muscle of the duct.
Answer:
Explanation:
Electromagnetic waves all travel at the speed of light when in vacuum, and essentially this same speed in normal air. Since wave speed is product of frequency and wavelength, c = f λ and λ = c/f = (3.00 x 108 m/s) / (7.5 x 1014 Hz) = 4.00 x 10-7 m = 400 x 10-9 m = 400 nm.
Answer:
increasing pressure inside the lymph capillary
Explanation:
Lymph is a fluid like the blood which carry the White blood cells which can fight against the infection. The lymph flows in separate vessels called lymphatic vessels.
The lymphatic vessel is very thin-walled smooth muscle containing tube-like structure which allows the transport of lymph.
The lymph vessel like blood vessel contains the valves called mini valves which prevent the backward flow of the lymph.
When the pressure in the tiny lymph capillaries which supplies lymph to the organs increases, the mini valves closes to prevent backflow of lymph and is the mechanism of lymph flow.
Thus, the selected option is the correct answer.
How does salinity change with temperature ?
<h3> C. as water warms, it contracts and becomes less salty ✓ ...</h3>
- Increases in temperatures of surrounding entities like ice and an increase in precipitation adds fresh water into the sea, which lower salinity ...
