Blood Vessels & Lymphatic System
Question | Answer |
---|---|
The structures that carry blood from the heart to the organs of the body and then back to the heart again are called (MADE OF ENDOTHELIUM ) | Blood Vessels |
The space within the blood vessels is called its | Lumen |
Vessels with thin walls are | Veins |
Vessels with thick walls | Arteries |
5 types of vessels are | 1. Arteries 2. Arterioles 3. Capillaries 4. Venules 5. Veins |
Vessel that carries blood AWAY from the heart (regardless of weather it carries oxygenated blood or deoxygenated blood) | Arteries |
Artery walls are composed of _______ muscle and ______ fibers that allow for ________ of vessels and the carrying of a _____. | Smooth, elastic , extension, pulse |
small arteries that arise via branching of large arteries | Arterioles |
_____ ____ and ____ ____ are also in the walls of arterioles. Arterioles branch to form _____ | smooth muscles, elastic fibers , capillaries |
The connections between arterioles and venules. | capillaries ( bed) |
It is at the capillary level where _____ and _____ pass from the blood into the ______ and where carbon dioxide and _____ materials pass from the tissues into the _____. | oxygen, nutrients , tissues , waste , blood |
small veins formed by the junction of a number of capillaries. | venules |
a vessel formed by the junction of a number of venules. | vein |
Veins are said to be formed by _____ and carry blood back to the _____. | tributaries, heart |
In certain veins that carry blood against gravity contain ______ that allow for the flow of blood only in __ direction , towards the heart. | Valves(cusps) , one. |
Blood moves past the valves via ______ of surrounding muscles | contraction |
Flow of blood ? Away from heart---to the heart | Artery-->Arterioles--> Capilaries--> Venules--> Veins |
Fluid filtered out of the blood______ each day exceeds that reabsorbed . this excess fluid is returned to the blood via ________. | capillaries, Lymphocytes |
The capillaries that pick up this _______ fluid are called _______ Capillaries, and they differ from blood capillaries in that they are ___________ tubes that begin____. | Excess, Lymphatic , endothelial , BLINDLY |
Lymphatic capillaries open at both ends or not ? | Not |
Lymphatic Capillaries will conduct the excess fluid called ____ towards ____ | Lymph, Veins |
As the lymph move towards the vein a number of them will joint to form and ________ Lymphatic vessel | Afferent |
Lymphatic vessels consist of _______ layers that comprise blood vessels. | similar |
Lymphatic vessels contain folds termed _____, that allow for flow of ___ in one direction, towards ____ | valves, lymph, veins |
there is ___ % blood capillaries | 90% |
there is ___ % lymphatic capillaries | 10 % |
Afferent lymphatic vessels convey lymph to _____ _____ , which function to filtering lymph | Lymph Nodes |
each lymph node has a _____ and a ____, through which lymph will filter | Cortex, Medulla |
Leaving the lymph node will be several _______ lymphatic vessels that also contain ____ . | Efferent, valves |
Efferent lymphatic vessels will pass the lymph to the ____ system | venous |
2 IMPORTANT LYMPHATIC DUCTS are | Right Lymphatic duct , Thoracic Duct |
this duct drains the right half of head, neck, chest, and right upper limb. | Right Lymphatic duct |
the duct that drains the rest of the body | Thoracic Duct |

Superficial Lymphatic vessels | Superficial cervical nodes, Axillary nodes, Thoracic Duct |
Lymph nodes are present in what regions ? | Neck, Axilla, Inguinal region (groin) |
