Health Science Theory Review

Respiratory, Hematology, CV, VS

The innermost, smooth lining of the heart is called this.

Endocardium

A blood vessel that carries blood away from the heart is a(n)

artery

The valve between the left atrium and left ventricle is called this.

bicuspid valve

The systolic phase of the cardiac cycle occurs when these chambers contract.

ventricles

The pericardium surrounds the heart and has ___ layers.

2

This blood type is known as the universal donor.

O-

Plasma serves this function.

transporting substances and providing volume

Type B blood makes antibodies against which type of blood?

Type A

This blood type is known as the universal recipient.

AB+

This formed element in the blood starts the blood clotting process.

Platelets

Electrical impulses in the heart terminate in these fibers that provide electricity to the ventricles.

Purkinje Fibers

Deoxygenated blood leaves the heart through these blood vessels.

pulmonary arteries

Electrical impulses start in the right atrium at this location.

SA node

The QRS complex in an EKG tracing contains this activity of the heart.

contraction of the vessels

The left atrium receives __________ blood from the ______________

oxygenated blood from the inferior/superior lungs/pulmonary veins

This flap of cartilage closes when you swallow to prevent food and water from traveling down your trachea.

epiglottis

C-shaped cartilage act to keep this portion of the airway from collapsing.

trachea

Oxygen exchange occurs at this terminal location of the respiratory system.

alveoli

Internal respiration occurs at this site in the body.

cellular level

Cilia perform this function in the respiratory system.

trapping pathogens and moving mucus

This number range represents a normal respiratory rate for an adult.

12-20

A pulse rate of 120 would be described in this way.

tachycardic

This is the phase of blood pressure when the heart is relaxing.

diastole

This number represents average normal blood pressure.

120/80

The most accurate temperature can be measured at this location.
