The nasal cavity is divided into two parts-the right and left nasal cavities, separated by a thin bony wall called septum. It is involved in the sense of smell, as small receptors located in the mucous membrane of the nasal cavity are responsible for detecting different odors.

Overall, the nasal cavity is a crucial part of the respiratory system and plays an important role in protecting the body from inhaled irritants, facilitating the sense of smell. Hence, the correct option is A.

which type of muscle tissue is the only one that can respond to voluntary nervous stimulation in most people?

Answers

The type of muscle tissue that can respond to voluntary nervous stimulation is skeletal muscle. This type of muscle is the most common of the three types of muscle (skeletal, cardiac, and smooth muscle) in the body.

Skeletal muscles are a voluntary type of muscle attached to bones of the skeleton by tendons.

These muscles (skeletal muscles) are voluntary because they are activated in response to information received from the somatic nervous system.

Skeletal muscles comprise approximately 30-40% of the total body mass.

the red blood cell goes into the kidney trunk and other lower limbs delivering oxygenated blood around the body. They typically last for 120

days before they die.

The blood enters the heart from left atrium. It leaves through the mitral valve into the left ventricle of the heart. The left ventricle then pumps blood through the aortic valve and into the aorta that feeds the rest of the body through a system of blood vessels.

What is function of lungs?

The lungs allow us to breathe and they carry oxygen into body (called  inhalation) and pass carbon dioxide out called exhalation.

Kidney remove toxins and waste, and excess water from the bloodstream, which is carried out of the body in the form of urine. They helped to produce hormones to form red blood cells, and they turn vitamin D into its active form in the body.
