26
Q

The left atrioventricular (AV) valve in the heart is also known as the:

A) pulmonary valve
B) aortic valve
C) mitral valve
D) tricuspid valve

A

C) mitral valve

The pulmonary and aortic valves are semilunar valves that are exit valves. AV valves are entrance valves and include the mitral (left) and tricuspid (right) valve.

A) superior vena cava 
B) aorta 
C) pulmonary artery

E) interior vena cava
A

C) pulmonary artery

The aorta and coronary arteries both carry oxygenated blood to supply the heart & body.The superior vena cava and inferior vena cava are veins, not arteries.

A) asthma 
B) emphysema 
C) croup 
D) pleurisy

D) sigmoid

30
Q

The membrane attached to the internal organs is the:

A) mucous membrane
B) visceral layer
C) parietal layer
D) epithelial layer

32
Q

The type of muscle responsible for producing peristalsis is:

A) cardiac 
B) skeletal 
C) smooth 
D) voluntary 
E) diaphragmatic
A

C) smooth

Smooth muscle is involuntary and is found in the walls of internal organs and passageways such as intestines, where peristalsis takes place.

33
Q

The sympathetic system of the autonomic nervous system is responsible for:

A) construction of the pupil of the eye
B) decrease in rate of heart beat
C) dilation of bronchi of the lungs
D) constriction of blood vessels to skeletal muscle
E) slowing the pulse
A

C) dilation of bronchi of the lungs

The sympathetic system is responsible for stimulating the body’s fight-or-flight response (stress). This response includes dilation of the bronchi.

The parasympathetic system returns the body to normal activity by constricting the pupil and the blood vessels and by decreasing the heart rate or slowing the pulse.

34
Q

The portion of the brain that aids in the coordination of voluntary muscle action is the:

A) cerebellum
B) thalamus
C) medulla oblongata
D) midbrain

A

A) cerebellum

The thalamus is responsible for relaying sensory impulses to the cerebral cortex of the brain. The medulla oblongata contains the respiratory center, the cardiac center, and the vasomotor center which regulates the contraction of smooth muscle in the blood vessel walls. The midbrain contains a relay center for certain eyes & ear reflexes.
