Arteries carry blood:
towards the heart
away from the heart
in the heart
What is the difference between the pulmonary vein and all the other veins of an adult?
It carries oxygen-poor blood, while the other veins carry oxygen-rich blood
It carries oxygen-rich blood, while the other veins carry oxygen-poor blood
It carries blood to the heart, while the other veins carry blood away from the hear
It carries blood away from the heart, while the other veins carry blood to the heart
Which of the following blood vessels contains blood with the highest concentration of dissolved oxygen?
aorta
femoral artery
subclavian artery
superior vena cava
How does the concentration of oxygen in the blood compare in the right ventricle and the left ventricle?
right ventricle has a low concentration of oxygen, left ventricle has a low concentration of oxygen
right ventricle has a low concentration of oxygen, left ventricle has a high concentration of oxygen
right ventricle has a high concentration of oxygen, left ventricle has a low concentration of oxygen
right ventricle has a high concentration of oxygen, left ventricle has a high concentration of oxygen
Which of the following arteries has the highest concentration of carbon dioxide?
aorta
carotid artery
pulmonary vein
mesenteric artery
What part of the body decreases the activity of the SA and AV nodes?
excretory system
respiratory system
sympathetic nervous system
parasympathetic nervous system
Skeletal muscle contractions account for the flow of blood in:
veins and arteries
arteries and capillaries
veins
arteries
Which of the following materials would be found in relatively high concentrations at the venous end of a capillary bed as compared to the arteriole end of a capillary bed?
glucose
oxygen
amino acids
carbon dioxide
The iliac vein:
carries blood away from the pelvic organs and lower abdomen
delivers blood from the aorta to the right subclavian artery
delivers nutrient rich blood from the intestines to the liver
delivers blood the the pelvis organs and lower abdomen
The superior vena cava:
carries blood from the heart
delivers blood to the cardiac muscles
receives blood from the upper extremities and head
delivers blood from the aorta to the right subclavian artery
Select the correct composition of blood:
55% plasma, <1% leukocytes, 45% erythrocytes
80% water, 4% neutrophils, 15% erythrocytes, 1% monocytes
45% plasma, <1% leukocytes, 55% erythrocytes
<1% plasma, <1% leukocytes, 99% erythrocytes
Anemia is the result of:
decreased production of red blood cells
loss of red blood cells from the body
the over-production of white blood cells
destruction of red blood cells within the body
How are white blood cells different than red blood cells?
They are smaller and carry more nutrients
They are larger and have a nucleus
There are more kinds of red blood cells
Select the correct process of blood clotting:
Blood Vessel is punctured -> platelets and damaged tissue cells release prothrombin activator, which initiates a cascade of enzymatic reactions -> fibrin threads form and trap red blood cells -> platelets congregate and form a plug
Blood Vessel is punctured -> fibrin threads form and trap red blood cells -> platelets congregate and form a plug -> platelets and damaged tissue cells release prothrombin activator, which initiates a cascade of enzymatic reactions
Blood Vessel is punctured -> platelets congregate and form a plug -> platelets and damaged tissue cells release prothrombin activator, which initiates a cascade of enzymatic reactions -> fibrin threads form and trap red blood cells
Blood cells are formed here:
Bone Marrow
Brain
Heart
Liver
The reason we always bleed when we are cut is because:
Our arteries are right under our skin
Even if the cut didn't hit a vein, blood will need to come towards it in order to clot the cut closed
We have capillaries all over our body
The cut just happens to cut a vein every time
The fetal circulatory system is exactly the same as adult circulatory system.
True
False
Select the functions of the lymphatic system:
Lymphatic nodes receive the fluids from vaccinations (like the covid vaccine) and mutate them often making us sick
Lymphatic capillaries absorb excess tissue fluid and return it to the bloodstream
Lymphatic capillaries absorb fats from the digestive tract and transport them to the bloodstream
Lymphoid organs held to defend the body against disease
We are all born with an innate immunity
True
False
Select the true statement:
T cells are produced in the thymus
B cells are produced in the thymus
Defence by T cells is called antibody-mediated immunity
There are two major types of B cells: helper and cytotoxic
