does anyone know how to make my voice deeper I'm ftm so I need help

Answers

gradually try speaking in a lower voice every day, but don’t do it for too long otherwise it will strain your vocal chords!! i’m sure there are videos out there as well :) <33

Hey I have a suggestion if you're still wondering!

So this method actually helped me a lot.

So start by tilting your head downward and by humming in your regular pitch. Then slowly raise your head while continuing to hum. And finally tilt your head back down. And now your voice is deeper than before you started the process.

This helps your vocal cords to become deeper. You can do this as many times you need until you're satisfied. But please be careful and don't do it too much. The first time I did it, I felt really proud. And the day after my throat hurt. I'd say that doing it only once actually lasts a couple hours!

Answers

2. Left atrium

3. Right ventricle

4. The pulmonary artery

5. Left ventricle.

Explanation:

The aorta is the main artery of the body that carries the oxygen-rich blood to all the body parts except the lungs from the left ventricle. It is divided into main coronary arteries or blood vessels.

The left atrium is one of the heart chambers, it is located in the upper part of the heart on the right side that receives the oxygenated blood from the lungs through the pulmonary vein.

The right ventricle is the chamber of the heart that pumps the deoxygenated blood to the pulmonary valve to MPA to the lungs to get oxygenated.

The pulmonary artery or the main PA (MPA) carries the oxygen-depleted blood from the right ventricle into the lungs, where blood becomes oxygenated.

The Left ventricle is the thickest muscle chamber of the heart responsible for the pumping oxygen-rich blood to the circulatory system and to the body through the aorta.
