Explanation
Involuntary muscles are not controlled by the central nervous system and are not under the control of the will. Involuntary muscles, also known as smooth muscles, are found in organs like the stomach, intestines, and blood vessels. They are controlled by the autonomic nervous system, which operates unconsciously and regulates bodily functions such as digestion, breathing, and heart rate. Therefore, the statement that involuntary muscles are controlled by the central nervous system and are under the control of the will is incorrect.

Explanation
The given statement is false. The left side of the heart actually deals with oxygenated blood. Oxygenated blood from the lungs enters the left atrium and then gets pumped into the left ventricle, which then pumps it out to the rest of the body. Deoxygenated blood, on the other hand, enters the right side of the heart.

Explanation
The external genitalia of a female are collectively known as the vulva. This includes the labia majora, labia minora, clitoris, vaginal opening, and urethral opening. The vulva is the visible part of the female reproductive system and plays a crucial role in sexual pleasure and childbirth. It is important to understand and recognize the correct terminology for the female external genitalia to ensure effective communication and understanding in medical, reproductive, and sexual health contexts.

Explanation
Having a basic knowledge of anatomy and physiology is important because it helps us understand how illnesses affect the human body. By understanding the normal structure and function of the body, we can better understand the changes that occur during illness and how they impact overall health. This knowledge allows healthcare professionals to accurately diagnose and treat illnesses, and also helps individuals make informed decisions about their own health and well-being. Therefore, the statement is true.

Explanation
The given answer is correct because the cerebrum, cerebellum, and brain stem are indeed three parts of the brain. The cerebrum is responsible for higher cognitive functions such as thinking, memory, and perception. The cerebellum plays a crucial role in coordinating movement, posture, and balance. The brain stem controls basic functions like breathing, heart rate, and consciousness. The other options, Dura mater and Pia mater, are actually layers of protective membranes surrounding the brain and not parts of the brain itself.

Explanation
The spine consists of 33 vertebrae, which allows for movement of the joints between the bones. Each vertebra is connected to the one above and below it, forming a flexible and strong structure that supports the body and protects the spinal cord. This large number of vertebrae provides the spine with the necessary flexibility and range of motion to perform various movements and activities.

Explanation
Light rays entering the eyeball do indeed pass through the cornea, aqueous humor, the lens, and the vitreous humor. The cornea is the transparent outer layer of the eye that helps to focus light onto the retina. The aqueous humor is a clear fluid that fills the space between the cornea and the lens, providing nutrients and maintaining the shape of the eye. The lens further focuses the light onto the retina, and the vitreous humor is a gel-like substance that fills the space between the lens and the retina, helping to maintain the shape of the eyeball. Therefore, the statement is true.

Explanation
The given statement is false. The respiratory system consists of air passages, such as the nose, mouth, trachea, bronchi, and lungs, but it does not include the heart. The heart is part of the circulatory system, which works in conjunction with the respiratory system to transport oxygen throughout the body.

Explanation
The kidneys are bean shaped and are embedded in a pad of fat which protects them. The given answer of 11cm suggests that the length of the kidneys is approximately 11 centimeters. This length is within a reasonable range for the size of kidneys in the human body.
