___ c The volume of blood that flows into the aorta with each heart beat is the stroke volume. Martha's stroke volume is 50 cm3 . The cardiac output is the amount of blood that flows into the aorta each minute. Calculate Martha's cardiac output in cm3 /min. Show your w

Answer and explanation:

For the cardiac output to be calculated, there are two variables needed: stroke volume and heart rate.

Stroke Volume x Heart Rate = Cardiac Output

A normal heart rate for a healthy person that is relaxing, should be between 60 and 100 beats per minute.

If we were to assume that Martha has an average heart rate of 80 beats per minute (bpm)...

50 cm3 x 80 beats per minute = 4000 cm3/min

This means that Martha's cardiac output is 4000 cm3 (4 liters) per minute. This is the amount of blood that is pumped by the heart into the aorta in a minute.

This is only an assumption since Martha's heart rate hasn't been given in the question. If her heart rate were to be 60 bpm, the cardiac output would then be 3000 cm3/min. With a heart rate of 100 bpm, the cardiac output should be 5000 cm3/min.

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:

myel/itis

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
