Vascular

What is the major and minor portion of the circulatory system? Blood-vascular system: [blank_start]Major[blank_end] Lymphatic system: [blank_start]Minor[blank_end]

Which systems carry oxygen and nutritive material to the tissues?

The skin, lungs, liver, and kidneys are the organs of excretion

Arteries: Carries blood [blank_start]away from[blank_end] the heart Veins: Carries blood [blank_start]back toward[blank_end] the heart

[blank_start]Systemic circulation[blank_end]: Carries oxygenated blood to the organs and tissues [blank_start]Pulmonary circulation[blank_end]: Takes blood to the lungs for CO2 exchange and for the reoxygenation of blood

Through the thin walls of the [blank_start]capillaries[blank_end], the blood discharges CO2 and absorbs oxygen from the air contained in the [blank_start]alveoli[blank_end]. The [blank_start]oxygenated[blank_end] blood passes onward through the pulmonary veins for return to the heart.

Deoxygenated blood is transported by the pulmonary [blank_start]arteries[blank_end], and oxygenated blood is transported by the pulmonary [blank_start]veins[blank_end].

What is the muscular wall of the heart called?

What is the membrane that lines the interior of the heart called?

What is the thin membrane that covers the heart?

Because of the force required to drive blood through the extensive systemic vessels, the myocardium is about three times as thick on the [blank_start]left[blank_end] side (the [blank_start]arterial[blank_end] side) as on the [blank_start]right[blank_end] (the [blank_start]venous[blank_end] side).

The heart is enclosed in the single-walled pericardial sac.

The aorta trunk begins what type of circulation?

Coronary arteries supply blood to what?

The right and left common carotids are for what type of circulation?

The right and left vertebral arteries are for what type of circulation?

[blank_start]Internal carotids[blank_end] bifurcate into anterior and middle cerebral arteries [blank_start]Basilar[blank_end] bifurcates into right and left posterior cerebral arteries [blank_start]Vertebral arteries[blank_end] unite to form basilar artery
