Q

What is the main job of the vascular system

A

To exchange materials between the blood and tissues, takes place in the capillaries. The arteries and veins are just as important by transporting blood between the capillaries and the heart

Q

What causes varicose vein

A

Sitting or standing in one place for long periods of time. Without contraction of the leg muscles blood tends to pool in the leg veins stretching their walls. When they become overly stretched the valves within them no longer close properly. These incompetent valves no longer prevent backflow of blood, leading to further pulling and further stretching of the walls of the veins.

When the blood pressure is in the Caval veins It approaches zero as it enters what area of the heart

A

Decreases

The right atrium

118
Q

What area of the heart creates pulmonary blood pressure

A

The right ventricle

119
Q

The result of pulmonary arterial pressure being low and even lower and pull Merry capillaries is important to prevent what

A

Filtration in pulmonary capillaries, which prevents tissue fluid from accumulating in the alveoli of the Lungs

120
Q

What is venous return

A

The amount of blood that returns to the heart by way of the veins

121
Q

Why is venous return important

A

Venous return is important because the heart can pump only the blood receives. If penis return decreases the cardiac muscle fibers will not be stretched, the force of ventricular systole will decrease in blood pressure will decrease

122
Q

What three mechanisms help promote venous return

A

Constriction of veins
The skeletal muscle pump
And the respiratory pump

123
Q

What does the smooth muscle in veins help to enable

What do the valves prevent

A

It enables them to constrict and force blood towards the heart
Backflow of blood

124
Q

What is the skeletal muscle pump especially effective for

A

The deep veins of the legs. These veins are surrounded by skeletal muscles that contract and relax
Contractions of the leg muscles squeeze the veins to force blood towards the heart

125
Q

What things does the respiratory pump affect

A

The veins that passed through the chest cavity

The pressure changes of inhalation and exhalation expand and compress the veins, and blood is return to the heart

126
Q

What is peripheral resistance

A

Resistance the vessels offer to the flow of blood.

127
Q

Why is it important to not exercise after you eat

A

There is not enough blood to completely supply oxygen to exercising muscles and an active digestive track at the same time.

*Example: after eating a large meal there is vasodilation in the digestive tract to supply more oxygenated blood for the digestive activities. To keep blood pressure within the normal range vasoconstriction must occur somewhere else in the body

128
Q

What does normal elasticity of the large arteries do for blood pressure

A

Lower systolic pressure raises diastolic pressure and maintains a normal pulse pressure

129
Q

What is pulse pressure

A

Pulse pressure is the difference between systolic and diastolic pressure the usual ratio of systolic to diastolic to post pressure is approximately 3:2:1.
Example: 120/80 blood pressure = 120:80:40, 40 would be the pulse pressure

130
Q

What determines that the Viscosity of the blood

A

Red blood cells, plasma proteins especially albumin

131
Q

What disorder causes too many Red blood cells

A

Polycythemia vera

132
Q

What will decrease blood viscosity and blood pressure

What occurs during this type of situation to maintain blood pressure as normal as possible

A 
Decreased number of red blood cells (as in anemia)
Decreased albumin (as in liver disease or kidney disease)

Vasoconstriction

133
Q

Up to what percentage of blood can a person survive a loss of

A

50% of the bodies total blood

134
Q

What hormone is secreted from the adrenal Medulla in stress situations

A

Norepinephrine and epinephrine

135
Q

What does norepinephrine stimulate

What does epinephrine cause

A

Vasoconstriction, which raises blood pressure

Epinephrine also causes vasoconstriction and increases heart rate and force of contraction which increased blood pressure

136
Q

What hormone is secreted by the posterior pituitary gland when the water content of the body decreases

A

Antidiuretic hormone (ADH)

137
Q

What does that antidiuretic hormone do

A

Increases the reabsorption of water by the kidneys to prevent further loss of water in urine and any further decrease in blood pressure

138
Q

What hormone from the adrenal cortex has a similar effect on blood as the antidiuretic hormone does

A

Aldosterone.

When blood pressure decreases secretion of aldosterone stimulates the reabsorption of Na+ ions by the kidneys. Waterfall sodium back to the blood which maintains blood volume to prevent further drop blood pressure

139
Q

What hormone is secreted by the atrium of the heart and functions in opposition to aldosterone

A

Atrial Natriuretic peptide (ANP)

Increases the excretion of Na+ ions and water by the kidneys, which decreased blood volume and lowers blood pressure

140
Q

When do precapillary sphincter’s dilate and constrict

A

They dilate and active tissues and construct and less active ones

141
Q

Why would arterioles constrict

A

To reduce blood flow to less active organs. This ensures that active organs will receive enough oxygen to function properly and blood pressure for the body will be maintained in normal limits

142
Q

What are the two mechanisms of systemic blood pressure

A

Intrinsic and nervous

143
Q

What does intrinsic mean

A

Within

144
Q

What is starlings law

A

When venous return increases, cardiac muscle fibers stretch, and the ventricles pump more forcefully

145
Q

What mechanism are the kidneys involved in

A

Renin angiotensin mechanism

146
Q

What do the kidney secrete one blood pressure decreases

A

Renin

147
Q

When renin is secreted a series of reactions occur and result in the formation of what

A

Angiotension II

148
Q

What does angiotension II cause

A

Vasoconstriction and stimulates secretion of aldosterone by the adrenal cortex which both increase blood pressure

149
Q

When a person has a blood level higher in sodium them potassium what does this cause

A

It will increase the muscle tone of the smooth muscle layer of blood vessels, which raises resting blood pressure

150
Q

What two mechanisms are directly involved in the regulation of blood pressure

A

The medulla and the autonomic nervous system

151
Q

What contains the vasomotor center

A

The medulla

152
Q

What does the vasomotor center consist of

A

A vasoconstrictor area and a vasodilator area

153
Q

Why do the veins of the legs deteriorate more so than other veins as we age

A

The walls of the veins in the legs have more pressure because blood is return to the heart against the force of gravity

154
Q

Vessels are active contributors to homeostasis

Arteries and veins help maintain blood pressure

Capillaries are sites for exchanges of materials between the blood and tissues

A

Just a summary of everything

155
Q

What is circulatory shock

A

Any condition in which cardiac output decreases to the extent that tissues are deprived of oxygen and waste products accumulate

156
Q

What are causes of circulatory shock

A

Cardiogenic shock
Hypovolemic shock
Anaphylactic shock
Septic shock

157
Q

What are the three stages of shock

A

Compensated shock
Progressive shock
Irreversible shock

158
Q

When does cardiogenic shock occur most often

A

After a severe myocardial infarction but also may result from ventricular fibrillation

159
Q

What is hypovolemic shock

A

The result of decreased blood volume due to hemorrhage

Other causes can be due to extreme sweating, extreme loss of water through kidneys (diuresis) or intestines(diarrhea)

160
Q

What is anaphylactic shock

A

Allergic reaction where histamine increase capillary permeability And vasodilation. Plasma is lost to tissue spaces which decreases blood volume blood pressure and cardiac output

161
Q

What is septic shock

A

The result of septicemia. Presence of bacteria in the blood

Inflammatory chemicals cause based dilation and loss of plasma into tissue spaces
