Cardio and Hormones Flashcards

Flashcards for reviewing lecture notes on the heart and endocrine system.

Atria

Receiving chambers of the heart.

Ventricles

Discharging chambers of the heart that pump blood out.

Superior and inferior vena cava

Returning blood to the right atrium

Pulmonary veins

Return blood to the left atrium

Pulmonary trunk

Carries blood away from the right ventricle

Atrioventricular valves

Structures between the atria and the ventricles

Mitral valve

Another name for the bicuspid valve

Chordae tendineae

Tendon cords that prevent backflow in the heart

Papillary muscles

Cardiac muscle to which the chordae tendineae attach

Systole

Contraction phase of the cardiac cycle

Diastole

Relaxation phase of the cardiac cycle

SA node (sinoatrial node)

The heart's pacemaker

Volume is not changing

Isovolumetric contraction

Cardiac cycle

The signal coming again, start that cycle over. Atrio systole, pump the blood out of the atria, the remaining amount going into the ventricles, then they relax, ventricles start contracting, close the AV valves, and we keep going over and over and over pumping that blood out.

Edema

Swelling due to a backlog of blood at the capillaries

Pulmonary edema

Backlog in the lungs

Systemic edema

Backlog of blood at the capillaries

S1 (lub)

Closing of the AV valves

S2 (dub)

Closing of the semilunar valves

Cardiac output

Heart rate multiplied by stroke volume

Cardioaccelerator center

Part of the ANS increases the heart rate.

Vagus nerve

Parasympathetic fibers that slow the heart rate down

Parasympathetic division

autorhythmicity or automaticity influenced by

Pacemaker potential

That neurotransmitters that are coming from the sympathetic and the parasympathetic fibers. epinepherine and norepinepherine vs acetylcholine.

Using parasympathetic innervation release acetylcholine

Using Sympathetic innervation acetylcholine when those channels are open, what does potassium do? Out. K?

Bradycardia

Heart rate that is slower than normal

Tachycardia

Heart rate that is faster than normal

Stroke volume

Volume Equals End Diastolic Volume

Stroke volume amount

Is your end diastolic volume after you finished relaxation minus your end systolic volume

EDV

amount of blood coming back Into the ventricles

EDV amount of blood coming back

how much the blood flow through the peripheral tissues

Filling time

Amount that the ventricles are in diastole is

Myocardial stretching

Is it to affect the contractile cells

Contractility

Is how much the muscle stretch and it going to affect Contract

Afterload

the resistance or the tension that the ventricles have to overcome to eject any blood in the first place

Heart failure

the heart is unable to meet your demands of your peripheral tissues

The left ventricular failure

Pulmonary edema and swelling in the systemic tissues Because it's not able to keep up. While the left ventricle is still pumping the share out

Body temperature and exercise

sympathetic stimulation and increase heart rate, Decrease heart rate, you would decrease cardiac

Body Blood volume

Exercise we are increasing our end diastolic volume. As we increase end diastolic volume, we are going to increase our preload because we've got more stretching going on

Change that increase or decrease that venous return

blood volume that would lead to lower venous return That would end up with a lower EDV. As we decrease the EDV, we decrease the stroke volume

Diaphragm is such a cool shape

epicardium,The outermost layer

Myocardium

that cardiac muscle tissue. Before we see the histology of it, what Some intercalated disc striated

Endocardium

simple squamous epithelial tissue, K, for both simple squamous epithelial tissue

Four Chamber Heart

outside of the atria have you little dog ear like such called little pouch called auricles

What anterior part of Surface

In the anterior interventricular artery

Specific neurotransmitters are released postganglionic fibers

Stimulation or inhibition of activity depends on response of a the response.
