Anatomy stuff.....?

Question

I have a test tomorrow on these words....

can someone explain to me what they mean?

I have the book definition but I don't really get it. like a sentence with the work in it might help.

Hemodynamica

capillary

lumen

vasoconsturiction

vasodilation

hypertension

hypovolemic shock

systolic blood pressure

hypotension

orthostatic hypotension

occlusion

and...... thrombophlebitis

even if you just help me with a couple of them, that would really be appriciated(: thank you

Answer 1

Capillary: a small blood vessel.

Vasoconstriction: Artery constriction

Vasodilation: When arteries are fully expanded

Hypertension: excess cardiac blood pressure

systolic blood pressure: the pressure with which blood is leaving the heart.

Hypotension: low blood pressure

Answer 2

hemodynamic - dynamics of blood (movement of the blood)

capillary - place of oxygen, water, carbon dioxide, nutrient and waste exchange in the body (smallest vein)

lumen - the channel of a tubular structure ie. the blood flows through the lumen of the arteries and veins.

vasoconstriction - constriction of the vascular system (veins)

vasodilation - dialation of the vascular system (veins)

hypertension - high blood pressure

hypovolemic shock - shock caused by low fluid volume in the body

systolic blood pressure - the pressure that is exerted on the arteries when the heart contracts ie. the first number reported - a blood pressure of 120/80- the systolic is 120

hypotension - low blood pressure

orthostatic hypotension - low blood pressure when you change positions from laying to sitting to standing

occlusion - blockage

thrombophlebitis - clot in an inflammed vein
