The Heart
The muscle of the heart is called the
myocardium
- the membranous sac surrounding the heart is called the pericardium
These are the part of the formed elements in the blood that function in blood clotting
Platelets/thrombocytes
- fragments of megakaryocytes formed in the red bone marrow
What antigen and what antibodies are present with type AB blood
A and B antigens
No antibodies
Internal respiration occurs here
gas exchange between the body cells and the capillaries
- diffusion (high to low) of O2 into the body cells from the capillaries, and CO2 into the capillaries from the body cells.
This is the term for lymphatic capillaries at the small intestine:
Lacteals
The diagnostic tool used for listening to the heart
stethoscope
The blood has two components; what are they and what are the percentages of each
Plasma - pale yellow, fluid portion of the blood 55%
Formed elements (erythrocytes, leukocytes, thrombocytes.
This blood type is the universal doner
Type O
No antigens are present on type O blood so it can't react with any of the antibodies present in the other blood types
If considering the Rh factor as well - type O negative
The majority of the lung consists of the
alveoli
-site of external respiration
The main function of lymph nodes
filter lymph
These vessels carry blood out of the heart
Arteries
Systemic arteries - carry O2 blood to the body
Pulmonary arteries - carry CO2 blood to the lungs
What part of the blood carries the majority of the CO2
Plasma - carries the waste product of cellular respiration to the lungs.
Type AB
Has AB antigens but no antibodies
If considering Rh factor - type AB+
This part of the respiratory system conditions the air
nasal cavity - warming, cleaning, and moisturizing
This organ of the lymphatic system filters blood
Spleen - removes pathogens, cancer cells, debris, and old RBC's.
This chamber of the heart pumps blood to the lungs
Right ventricle
These transport O2
Erythrocytes (red blood cells)
- biconcave & lacking a nucleus - allows for increased surface area and increased hemoglobin
- small and flexible so they can fit through tiny capillaries.
This causes hemolytic disease of newborns
Rh - mom and Rh+ baby
Mom produces antibodies to the baby's d-antigens, then they attack the baby's blood cells.
This part of the respiratory system has C-shaped cartilage
trachea
This organ of the lymphatic system is the site of T-lymphocyte maturation
Thymus
These allow the passage of blood between the chambers of the heart
Valves
Semi-lunar: Pulmonary and aortic valves
Atrioventricular: Tricuspid and bicuspid/mitral
This disorder is the result of decreased hemoglobin in the blood
Anemia
This the test that is performed to determine if blood types are compatible
Agglutination test
The respiratory centre is located here
medulla oblongata
This is where the formed elements of blood are formed and is considered an organ of the lymphatic system
Red bone marrow - T-lymphocytes mature here.
