Sinusoid (Noun)

The curve of y=sin x.

Nouns denoting two and three dimensional shapes.

The graph of y=sin x is a classic example of a sinusoid, oscillating smoothly between positive and negative values.
The sinusoid curve is often used to model periodic phenomena, such as sound waves or light waves.
By analyzing the sinusoid, we can identify key features such as amplitude, period, and phase shift.
The sinusoid has many real-world applications, including electrical engineering, signal processing, and medical imaging.
When graphed on a coordinate plane, the sinusoid forms a smooth, continuous curve with no sharp corners or discontinuities.

Tiny endothelium-lined passages for blood in the tissue of an organ.

Nouns denoting body parts.

The liver contains many sinusoids, tiny passages where oxygen and nutrients are exchanged with the liver cells.
In the liver, the sinusoids are surrounded by Kupffer cells, which play a role in immune function.
The sinusoids in the spleen act as a filter, removing old and damaged red blood cells from the circulation.
The bone marrow contains sinusoids that allow the exchange of oxygen, nutrients, and waste products between the blood and the bone cells.
In the lymphoid organs, the sinusoids provide a route for the passage of lymphocytes and other immune cells through the tissue.
