Q

Atrium

A

Each of the two upper cavities of the heart from which blood is passed to the ventricles. The right atrium receives deoxygenated blood from the veins of the body; the left atrium receives oxygenated blood from the pulmonary vein

Q

Tricuspid valve

A

Aka right atrioventricular valve, is on the right dorsal side of the mammalian heart. The function of the valve is to prevent back flow of blood into the right atrium

Mitral valve

A

Aka left atrioventricular valve, prevents the flow of blood from the ventricles back into the atria during ventricular contraction

Q

Sympathetic nervous system

A

The part of the autonomic nervous system consisting of nerves arising from ganglia near the middle part of the spinal cord, supplying internal organs, blood vessels, and glands, and balancing the action of the parasympathetic nervous system

Q

Parasympathetic nervous system

A

The part of the autonomic nervous system that counter balances the sympathetic nerves

16
Q

Bradycardia

A

Fewer than 60 heart beats per minutes

17
Q

Tachycardia

A

More than 100 heart beats per minute

18
Q

Electrocardiogram

A

A graphic representation of the electrical activity of the heart, which can be recorded at the surface of the body

19
Q

P-wave

A

Represents atrial depolarization, which causes atrial contraction. It is generated by the changes in the electrical potential of cardiac muscles

20
Q

T-wave

A

Is caused by electrical potential generated as the ventricles recover from the state of depolarization. It represents the repolarization (or recovery) of the ventricles

21
Q

QRS complex

A

The name for the combination of three graphical deflections see on an ECG. It corresponds to the depolarization of the right and left ventricles of the heart. Composed of Q, R, and S, waves respectively

22
Q

Depolarization

A

The reversal of the membrane electrical potential, whereby the normally negative potential inside the membrane becomes slightly more positive and the outside become slightly negative

23
Q

Repolarization

A

Electrical potential generated as the ventricles recover from the state of depolarization. Cause of at-wave.

24
Q

Arterial system

A

Arteries that carry blood away from the heart

25
Q

Venous system

A

Veins that return blood toward the heart

26
Q

Arteries

A

Connective muscular tube that rapidly transport blood pumped from the heart

27
Q

Arterioles

A

Small branches of the arteries that act as control vessels through which blood enters the capillaries. They have strong, muscular walls that are capable of closing the arteriole completely or allowing it to be dilated severalfold, thus vastly altering blood flow tit the capillaries in response to the needs of the tissues.

28
Q

Capillaries

A

Thin, permeable walls whose primary function is to exchange oxygen, fluid, nutrients, electrolytes, hormones, and other substances between the blood and interstitial fluid in the various tissues of the body

29
Q

Venules

A

Collectors of blood from the capillaries that gradually converge into progressively larger veins

30
Q

Veins

A

Connected muscular tubes which transport blood back to the heart

31
Q

Hemoglobin

A

An iron-protein molecule carried by the red blood cells. It transports oxygen. Also acts as an acid-base buffer, a regulator of hydrogen ion concentration, which is crucial to the rates of chemical reactions in cells

32
Q

Red blood cells

A

The major component of blood, contains large quantity of carbonic anhydrase, which catalyzes the reaction between carbon dioxide and water to facilitate carbon dioxide removal
