• Veins that are the only veins that carries oxygenated blood

• Arteries that are the only veins that carries unoxygenated blood

• Veins that Deliver deoxygenated blood to the heart

• Arteries that carry oxygenated blood away fro the heart

• Small blood vessels that connects arteries and veins?

• Pathway of blood to and from the heart?

• Carbon dioxide diffuses into the?

• Oxygen diffuses into?

• What part sends the strongest blood?

• Oxygenated Blood flow via _____?But, naay options,1. Into the brain2. Into the arms3. Into the torso and legs

• Respiratory system of the plant

• Structure of circulatory system

• Function of circulatory system?

• Two types of circulatory system?

• Blood bathes the organ directly in an open circulatory

• Blood is confined to vessels and is distinct from the interstitial fluid

• A fish heart has two main chambers

frog has three chambered heart?

Reptile have double circuit

Reptiles has _-_ chambered hearts?

• a cone-shaped, muscular organ located between the lungs behind the sternum

• is the outer membranous sac with lubricating fluid.

• Heart has how many chambers?

• a wall dividing the right and left sides.

• occur between the atria and ventricles.

• Examples.

• tricuspid located at openings of arteries

• prevents back flow of blood when ventricles empty.

• Example?

• Each heartbeat is called a

• the contraction of heart chambers (ventricles) and force blood into arteries

• the contraction of heart chambers (ventricles) and force blood into arteries

• are due to the closing of the atrioventricular valves, followed by the closing of the semilunar valves:

• heart begins systole; AV valves close

• heart begins diastole; SL valves close

initiates the heartbeat and causes the atria to contract on average every 0.85 seconds; located in the right atria.

• conveys the stimulus and initiates contraction of the ventricles; located in the right atria

• which circulates blood through the lungs (heart and lung)

• which circulates blood to the rest of the body (heart and body cells)

• Pulmunary circuit starts in?

• Systemic circuit starts in?

• Originate as lymph capillaries

– Drains right side of head & neck, right arm, right thoracic area– Empties into the right subclavian vein

– Drains the rest of the body– It serves the lower extremities, the abdomen, the left arm, and the

left side of both the head and the neck. – Empties into the left subclavian vein

• System that,• collects toxins in the body• the "garbage collector", sucking up

metabolic garbage, and toxins from the extracellular fluid of every organ.

• Once tissue fluid enters the lymphatic vessels

• is localized swelling caused by the accumulation of tissue fluid.

• transports disease-fighting white blood cells (lymphocytes) and circulates only as a result of muscle movement

• , bean-shaped swellings where lymph is filtered and any foreign matter is engulfed and removed.

• nodes are in the groin

• nodes are in the armpits.

• tonsils located on either side of the posterior oral cavity are most apt to be infected.

• Posterior-lateral walls of the oropharynx

• Posterior wall of nasopharynx

• Base of tongue

• Largest lymphatic organ

• is the site of origination for all types of blood cells, including the five types of white blood cells.

• marrow contains ______that are ever capable of dividing and producing cells that go on to differentiate into the various types of blood.

• Carry water and minerals from the roots to the leaves.

• Wood strength comes from a chemical called ____.

• After forming wood, they die and make long thin tubes called?

• carry glucose from the leaves to other parts of the plant.

• the central part of the root or stem containing the tissues derived from the procambium.

• main water conducting vessel; wider in diameter; more efficient due to of perforations; with few but larger pits;

• narrow in diameter; with smaller but numerous pits; less efficient due to absence of perforation; ends are tapered

• quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects such as capillary action (which is caused by surface tension)

• Water moves in the direction it does (root to leaf) because of the

• needed to to pull molecules away from the film of water coating air spaces within the spongy parenchyma of the leaf.

• Four important forces combine to transport water solutions from the roots, through the xylem elements, and into the leaves.

• involves the pulling of water up through the xylem of a plant utilizing the energy of evaporation and the tensile strength of water.

• is the attractive force between water molecules and other substances. Because both water and cellulose are polar molecules there is a strong attraction for water within the hollow capillaries of the xylem.

• is the attractive force between molecules of the same substance.

• can be thought of as a stress placed on an object by a pulling force.

• osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves.

• the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses.

• is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation. 

• Ions can cross the endodermal cell membranes passively by being "swept" into the stele with water

• Movement into xylem is blocked by special barrier called?

• Water and mineral normally can travel through the porous cell walls of the root cortex

• involves special openings between adjacent cell walls called?

• the best-supported theory to explain the movement of food through the phloem

• areas of the phloem with large pores.
