Which organ receives immature T cells, then raises them to maturity, the releases them? 32. What is found in the spleen, red bone marrow and lymph nodes that fight microbes- 33. What makes the lymph fluid move through the body?Explanation / Answer
8. Apex:From the base of the heart ,projects forward downward and to the left ending at the apex
9.From largest to smallest : 1) Arteries(Aorta (the largest artery, carries blood out of the heart)/veins(vena cava being largest)
2)Arterioles/venules
3)Capillaries
10.
Anatomy of the heart consits of 2 atria and 2 ventricle.Each side of the heart is dicided into uper chamber and lower chamber.The upper chambers on either side are called atria while lower are ventricle
walls of the atria are thinner with low blood pressure, while those of the ventricles are thicker with high blood pressure.
The atrium is a chamber in which blood enters the heart, as opposed to the ventricle, where it is pushed out of the organ.
Atrium have no inlet valves while the ventricles do
Atrium have milder and gentle contractions in comparison to ventricles
11.Pectinate muscles
12Varicose veins.are twisted,enlarged veins near the surface of theskin.This is caused due to pressure build up due to collection of blood in the lower legs.This collection of blood is caused by the inabilty of the one way valves of the veins in the lower leg to pump the blood up toward the heart .Factors that increase the risk for vericose veins are:
Age:causes wear and tear of valves that build up the veins.
Pregnency
Family History
Obesity
Standing /sitting for long duration.
13.Vasoconstriction is the narrowing (constriction) of blood vessels by small muscles in their walls. When blood vessels constrict, blood flow is slowed or blocked.This decreased blood flow leads to body heat retention or increased vascular resistance
14.Oxygen rich blood travels through the Arteries and Oxygen poor blood travels through the Veins. EXCEPT: Oxygen poor Blood traveling from the heart to the lungs goes through the Pulmonary Arteries and Oxygen rich blood going back to the heart from the lungs travels through the Pulmonary Veins
16.Serotonin,Epinephrine ,non epinephrine and angiotensin II act as vasocontrictors.
17.Polycythemic(due to Primary polycythemia)
18.Embolus
19. individual having blood type A can receive blood from blood types A (A+,A-)and O(O+,O-).
21.Haemoglobin is the oxygen carrier protien in the blood
22.Marked by the presence of granules in cytoplasm.Granulocytes are:
Eosinophils
Neutophils
Basophils
Mast cells
23.Blood proteins are synthesised in the liver except for gamma globulins which are synthesised fin the cells of reticulo-endothelial system
24.At sites of vascular injury, platelets adhere and aggregate on the exposed subendothelial matrix to form a platelet plug, which, iseals the vessel and limits blood loss.
So its the property of platelets to stick to each other that prevents blood loss
25.White blood cell growth factors are proteins that help the body produce white blood cells.They are also known as Colony simulating factors
26.For adults a count of more than 11,000 white blood cells(leukocytes) in a microliter of blood is considered a high white blood cell count which is indicative of infection.
27.Lymphocytes are the special blood cells which attack the foreign substances ,eother bu producing antoibodies(B cell) or recognising and attaching to them(T cell)
28.blood type O
29.Flat shape increases the cell’s surface area and facilitates contact with oxygen molecules. Due to its shape, the red blood cell can load up with far more oxygen molecules than it could if shaped like an ordinary cell, and is able to carry them more easily to the tissues where they are needed due unimpeded passage through the tiny capillaries because of the flattened structure.
30it is kidney-shaped capsule in the lymph vessels that are filled with B cells and T cells forming a part of lymphatic system
31.Thymus
32.Natural killer cells
33.The lymph is moved through the body in its own vessels
20.A and O
