What is the internal system of interconnected tubes and vessels called in some terrestrial plants?
any plant tissue with water conducting cells which cause the hardening of plants.These cells are also involved in transporting other solutes from one part of the plant to another. for example the xylem which conducts water and ions and the phloem which conducts sugars .
Referring to a state of insufficient vascular volume in the heart?
Hypovolemia
Why do the spores of vascular plants have such a thick wall?
The wind enhances spore dispersal thereby enabling vascular plants to spread and reproduce in new habitats. The thick wall confers integrity, and the spore can survive harsh environmental conditions during propagation.
What is air embolisms?
You get the air embolism, when there is air in the vascular system. It may be accidental during intravenous fluid administration. You get the air embolism, when you come out of the deep sea very rapidly.
Do vegetables contain starch or fiber?
lemon, lime, and pretty much healthy thing that grow from trees.
What is the first phase of hemostasis in which vasoconstriction occurs?
Vascular phase
Does calcium has any role in vasoconstriction?
Yes it does, as a matter of fact calcium plays a huge role in muscle contraction, as so in the smooth vascular muscle.
Does adh cause vasoconstriction?
ADH does not exactly cause the vasoconstriction but increases the peripheral vascular resistancewhich results increases of arterial blood pressure
What chemical produces vascular spasms?
serotonin
Is Vasodilation is a widening of the lumen due to smooth muscle contraction?
No.Vasodilatation, ie, widening of vascular lumen is caused due to vascular smooth muscles' relaxation.While, vasoconstriction, ie, decrease in diameter of the lumen is caused due to smooth muscle contraction.
What is vascular inflammation?
immediate and brief vasoconstriction of the blood vessels in the injured area; they quickly dilate; redness, warmthyes it does if you want you can go to a local pharmacy or drug store and look at ibuprofen and it says anti inflamatory
Why is the diastolic pressure always above zero?
The diastolic pressure is the pressure inside the arteries while the heart is at rest. The vascular walls maintain this pressure thru vasoconstriction. Zero blood pressure is not conducive to life.
What does a vascular plant need to have to be a vascular plant?
Vascular plants have lignified tissues that are used to get water, minerals, and other products through the plant. Lignin is a chemical compound that is found in the cell walls of plants.
What is a vascular effect of histamine released from mast cells?
vasodialation
What are plants that have tube like structures for water and nutrients to travel up and down from roots to leaves?
Plants that have tubes are called vascular plants.
What is the medical term meaning around a vessel?
vascular- pertaining to vesselsarterial- pertaining to arteriesvenous- pertaining to veinsVery simple...it is "vaso". As in vasodialation or vasoconstriction.
Hoe does SVR affect blood pressure?
The resistance offered by the peripheral circulation is known as the systemic vascular resistance (SVR). Vasoconstriction (i.e., decrease in blood vessel diameter) increases SVR, whereas vasodilation (increase in diameter) decreases SVR. this constriction and dialation decreases or increases the volume in which the vessles can potensially hold. the blood pressure is subsequantly altered as more or less vascular space is provided.
