1. How do your eyes work? What is the difference between focal vision and peripheral vision?

Olin [163]

Answer:

1 When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photo receptors turn the light into electrical signals.

These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.Focal vision is involved in examining and recognizing objects related with the macular area of the retina whereas peripheral vision is vision resulting in stimulation of the retina outside the macula. An example of peripheral vision would be looking straight ahead while also being able to see on the side by the eye.

Explanation:

2The pituitary gland is enveloped by dura and sits within the sella turcica of the sphenoid bone. The sella turcica is a saddle-shaped depression that surrounds the inferior, anterior, and posterior aspects of the pituitary.When a pituitary tumor pushes the optic chiasm, it causes visual loss in both eyes. In addition to the optic nerve, which brings vision from the eye to the brain, there are also several other nerves near the pituitary gland that travel to the eyes and help them move normally.

Valves are like flaps or lids that are used to transport blood from the atria to the ventricles. They act as inlets and outlets of blood.

Explanation:

The atrioventricular valves are located Left and right that are in the middle of atria and ventricle on both sides of the heart while two semilunar valves separate the right and left ventricles from the pulmonary valve and aortic valve.

The Atrioventricular valves are the mitral valve and the tricuspid valve. Mitral valve is in the left side and tricuspid valve is in the right. they both are separated by the atrium and ventricle

The two semilunar valves are the pulmonary valve and aortic valve. the pulmonary valve is on the right side separated by the right ventricle and pulmonary artery. The aortic valve is on the left and is separated by the left ventricle and aorta.

Capecitabine has been prescribed for a client with breast cancer and the test that will be done periodically is Complete Blood Count.

<h3>What is complete blood count?</h3>

A complete blood count (CBC) is a blood test used to assess your general health and find a number of illnesses, such as leukemia, anemia, and infections.

A complete blood count test evaluates several elements and characteristics of your blood, such as:

A red blood cell carries oxygen.

Virus-fighting white blood cells

The oxygen-carrying protein in red blood cells is called hemoglobin.

Hematocrit, which is the ratio of red blood cells to plasma, the liquid component of your blood

The blood clotting factor platelets

A complete blood count that reveals abnormal increases or declines in cell counts may point to an underlying medical problem that necessitates additional testing.
